fm93c56a eeprom (the device) and is generated by a master that is controlling the device. a high level on this pin selects the device and a low level deselects the device. all serial communications with the device is enabled only when this pin is held high. however this pin cannot be permanently tied high, as a rising edge on this signal is required to reset the internal state-machine to accept a new cycle and a falling edge to initiate an internal programming after a write cycle. all activity on the sk, di and do pins are ignored while cs is held low. serial clock (sk) this is an input pin to the device and is generated by the master that is controlling the device. this is a clock signal that synchronizes the communication between a master and the device. all input informa- tion (di) to the device is latched on the rising edge of this clock input, while output data (do) from the device is driven from the rising edge of this clock input. this pin is gated by cs signal. serial input (di) this is an input pin to the device and is generated by the master that is controlling the device. the master transfers input informa- tion (start bit, opcode bits, array addresses and data) serially via this pin into the device. this input information is latched on the rising edge of the sck. this pin is gated by cs signal. serial output (do) this is an output pin from the device and is used to transfer output data via this pin to the controlling master. output data is serially shifted out on this pin from the rising edge of the sck. this pin is active only when the device is selected. organization (org) this is an input pin to the device and is used to select the format of data (16-bit or 8-bit). if this pin is tied high, 16-bit format is selected, while if it is tied low, 8-bit format is selected. depending on the format selected, fm93c56a requires 7-bit address field (for 16-bit data format) or 8-bit address field (for 8-bit data format). refer table 1 and table 2 for more details. this pin is internally pulled-up to v cc . hence leaving this pin unconnected would default to 16-bit data format. microwire interface a typical communication on the microwire bus is made through the cs, sk, di and do signals. to facilitate various operations on the memory array, a set of 7 instructions are implemented on fm93c56a. the format of each instruction is listed under table 1 (for 16-bit format) and table 2 (for 8-bit format). instruction each of the above 7 instructions is explained under individual instruction descriptions. start bit this is a 1-bit field and is the first bit that is clocked into the device when a microwire cycle starts. this bit has to be 1 for a valid cycle to begin. any number of preceding 0 can be clocked into the device before clocking a 1 . opcode this is a 2-bit field and should immediately follow the start bit. these two bits (along with 2 msb of address field) select a particular instruction to be executed. address field depending on the selected organization, this is a 8-bit or 9-bit field and should immediately follow the opcode bits. in fm93c56a, only the lsb 7 bits (or 8 bits) are used for address decoding during read, write and erase instructions. during all other instruc- tions, the msb 2 bits are used to decode instruction (along with opcode bits). data field depending on the selected organization, this is a 16-bit or 8-bit field and should immediately follow the address bits. only the write and wrall instructions require this field. msb bit (d15 or d7) is clocked first and lsb bit (d0) is clocked last (both during writes as well as reads). table 1. instruction set (16-bit organization) instruction start bit opcode field address field data field read 1 10 x a6 a5 a4 a3 a2 a1 a0 wen 1 00 1 1xxxxxx

2k-bit serial cmos eeprom (microwire tm synchronous bus) functional description a typical microwire cycle starts by first selecting the device (bringing the cs signal high). once the device is selected, a valid start bit ( 1 ) should be issued to properly recognize the cycle. following this, the 2-bit opcode of appropriate instruction should be issued. after the opcode bits, the 8-bit (or 9-bit) address information should be issued. for certain instructions, some of the bits of this field are don t care values (can be 0 or 1 ), but they should still be issued. following the address information, depend- ing on the instruction (write and wrall), 16-bit data (or 8-bit) is issued. otherwise, depending on the instruction (read), the device starts to drive the output data on the do line. other instructions perform certain control functions and do not deal with data bits. the microwire cycle ends when the cs signal is brought low. however during certain instructions, falling edge of the cs signal initiates an internal cycle (programming), and the device remains busy till the completion of the internal cycle. each of the 7 instructions is explained in detail in the following sections. 1) read (read) read instruction allows data to be read from a selected location in the memory array. input information (start bit, opcode and address) for this instruction should be issued as listed under table 1 or table 2. upon receiving a valid input information, decoding of the opcode and the address is made, followed by data transfer from the selected memory location into a 16-bit serial-out shift register. this 16-bit data (or 8-bit data) is then shifted out on the do pin. msb of the data (d15 or d8) is shifted out first and lsb (do) is shifted out last. a dummy-bit (logical 0) precedes this data output string. output data changes are initiated on the rising edge of the sk clock. after reading the 16-bit (or 8-bit) data, the cs signal can be brought low to end the read cycle. refer read cycle diagram . 2) write enable (wen) when v cc is applied to the part, it powers up in the write disable (wds) state. therefore, all programming operations must be preceded by a write enable (wen) instruction. once a write enable instruction is executed, programming remains enabled until a write disable (wds) instruction is executed or v cc is completely removed from the part. input information (start bit, opcode and address) for this wen instruction should be issued as listed under table 1 or table 2. the device becomes write- enabled at the end of this cycle when the cs signal is brought low. execution of a read instruction is independent of wen instruc- tion. refer write enable cycle diagram. 3) write (write) write instruction allows write operation to a specified location in the memory with a specified data. this instruction is valid only when device is write-enabled (refer wen instruction). input information (start bit, opcode, address and data) for this write instruction should be issued as listed under table 1 or table 2. after inputting the last bit of data (d0 bit), cs signal must be brought low before the next rising edge of the sk clock. this falling edge of the cs initiates the self-timed programming cycle. it takes t wp time (refer appropriate dc and ac electrical charac- teristics table) for the internal programming cycle to finish. during this time, the device remains busy and is not ready for another instruction. the status of the internal programming cycle can be polled at any time by bringing the cs signal high again, after t cs interval. when cs signal is high, the do pin indicates the ready/busy status of the chip. do = logical 0 indicates that the programming is still in progress. do = logical 1 indicates that the programming is finished and the device is ready for another instruction. it is not required to provide the sk clock during this status polling. while the device is busy, it is recommended that no new instruction be issued. refer write cycle diagram. it is also recommended to follow this instruction (after the device becomes ready) with a write disable (wds) instruction to safeguard data against corruption due to spurious noise, inadvert- ent writes etc. 4) write all (wrall) write all (wrall) instruction is similar to the write instruction except that wrall instruction will simultaneously program all memory locations with the data pattern specified in the instruction. this instruction is valid only when device is write-enabled (refer wen instruction). input information (start bit, opcode, address and data) for this wrall instruction should be issued as listed under table 1 or table 2. after inputting the last bit of data (d0 bit), cs signal must be brought low before the next rising edge of the sk clock. this falling edge of the cs initiates the self-timed programming cycle. it takes t wp time (refer appropriate dc and ac electrical charac- teristics table) for the internal programming cycle to finish. during this time, the device remains busy and is not ready for another instruction. status of the internal programming can be polled as described under write instruction description. while the device is busy, it is recommended that no new instruction be issued. refer write all cycle diagram. table 2. instruction set (8-bit organization) instruction

disable (wds) instruction disables all programming opera- tions and should follow all programming operations. executing this instruction after a valid write instruction would protect against accidental data disturb due to spurious noise, glitches, inadvert- ent writes etc. input information (start bit, opcode and address) for this wds instruction should be issued as listed under table 1 or table 2. the device becomes write-disabled at the end of this cycle when the cs signal is brought low. execution of a read instruction is independent of wds instruction. refer write disable cycle diagram. 6) erase (erase) the erase instruction will program all bits in the specified location to logical 1 state. input information (start bit, opcode and address) for this wds instruction should be issued as listed under table 1 or table 2. after inputting the last bit of data (a0 bit), cs signal must be brought low before the next rising edge of the sk clock. this falling edge of the cs initiates the self-timed programming cycle. it takes t wp time (refer appropriate dc and ac electrical characteristics table) for the internal programming cycle to finish. during this time, the device remains busy and is not ready for another instruction. status of the internal programming can be polled as described under write instruction description. while the device is busy, it is recommended that no new instruc- tion be issued. refer erase cycle diagram. 7) erase all (eral) the erase all instruction will program all locations to logical 1 state. input information (start bit, opcode and address) for this wds instruction should be issued as listed under table 1 or table 2. after inputting the last bit of data (a0 bit), cs signal must be brought low before the next rising edge of the sk clock. this falling edge of the cs initiates the self-timed programming cycle. it takes t wp time (refer appropriate dc and ac electrical characteristics table) for the internal programming cycle to finish. during this time, the device remains busy and is not ready for another instruction. status of the internal programming can be polled as described under write instruction description. while the device is busy, it is recommended that no new instruction be issued. refer erase all cycle diagram. note: the fairchild cmos eeproms do not require an erase or erase all instruction prior to the write or write all instruction, respectively. the erase and erase all instructions are included to maintain compatibility with earlier technology eeproms. clearing of ready/busy status when programming is in progress, the data-out pin will display the programming status as either busy (low) or ready (high) when cs is brought high (do output will be tri-stated when cs is low). to restate, during programming, the cs pin may be brought high and low any number of times to view the programming status without affecting the programming operation. once programming is completed (output in ready state), the output is cleared (returned to normal tri-state condition) by clocking in a start bit. after the start bit is clocked in, the output will return to a tri-stated condition. when clocked in, this start bit can be the first bit in a command string, or cs can be brought low again to reset all internal circuits. refer clearing ready status diagram. related document application
