The device features fully static operation requiring no external clocks or timing strobes, with equal address access and cycle times. It requires a single 2.7 to 3.6V supply. This device has an automatic power-down feature, reducing the power consumption by over 99% when deselected. The M68AW128M is available in TFBGA48 (0.75 mm pitch) and in TSOP44 Type II packages. In addition to the standard version, the packages are also available in Lead-free version, in compliance with JEDEC Std J-STD-020B, the ST ECOPACK 7191395 Specification, and the RoHS (Restriction of Hazardous Substances) directive. All packages are compliant with Lead-free soldering processes. Figure 2. Logic Diagram VCC Table 1.

An Output Enable (G) signal provides a high speed tri-state control, allowing fast read/ write cycles to be achieved with the common I/O data bus. Operational modes are determined by device control inputs W, E, LB and UB as summarized in the Operating Modes table (see Table 2). Read Mode The M68AW128M is in the Read mode whenever Write Enable (W) is High with Output Enable (G) Low, and Chip Enable (E) is asserted. This provides access to data from eight or sixteen, depending on the status of the signal UB and LB, of the 2,097,152 locations in the static memory array, specified by the 17 address inputs. Valid data will be available at the eight or sixteen output pins within t AVQV after the last stable address, providing G is Low and E is Low. If Chip Enable or Output Enable access times are not met, data access will be measured from the limiting parameter (tELQV, tGLQV or t BLQV) rather than the address. Data out Table 2. Operating Modes Operation Deselected Deselected Lower Byte Read Lower Byte Write Output Disabled Upper Byte Read Upper Byte Write Word Read Word Write Note: 1. X = VIH or VIL. may be indeterminate at tELQX, tGLQX and tBLQX but data lines will always be valid at tAVQV. Write Mode The M68AW128M is in the Write mode whenever the W and E are Low. Either the Chip Enable input (E) or the Write Enable input (W) must be deasserted during Address transitions for subsequent write cycles. When E (W) is Low, and UB or LB is Low, write cycle begins on the W (E)'s falling edge. When E and W are Low, and UB = LB = High, write cycle begins on the first falling edge of UB or LB. Therefore, address setup time is referenced to Write Enable, Chip Enable or UB/LB as t AVWL, tAVEL and tAVBL respectively, and is determined by the latter occurring edge. The Write cycle can be terminated by the earlier rising edge of E, W or UB/LB. If the Output is enabled (E = Low, G = Low, LB or UB = Low), then W will return the outputs to high impedance within t WLQZ of its falling edge. Care must be taken to avoid bus contention in this type of operation. Data input must be valid for tDVWH before the rising edge of Write Enable, or for tDVEH before the rising edge of E, or for tDVBH before the E VIH X VIL VIL VIL VIL VIL VIL VIL W X X VIH VIL VIH VIH VIL VIH VIL G X X VIL X VIH VIL X VIL X LB X VIH VIL VIL X VIH VIH VIL VIL UB X VIH VIH VIH X VIL VIL VIL VIL DQ0-DQ7 Hi-Z Hi-Z Data Output Data Input Hi-Z Hi-Z Hi-Z Data Output Data Input DQ8-DQ15 Hi-Z Hi-Z Hi-Z Hi-Z Hi-Z Data Output Data Input Data Output Data Input Power Standby (ISB) Standby (ISB) Active (ICC) Active (ICC) Active (ICC) Active (ICC) Active (ICC) Active (ICC) Active (ICC) 8/22 M68AW128M MAXIMUM RATING Stressing the device above the rating listed in the Absolute Maximum Ratings table may cause permanent damage to the device.
