edi8f3232c 32kx32 sram module 1 edi8f3232c rev. 6 1/98 eco #9601 features pin configurations and block diagram 32kx32 static ram cmos, high speed module the edi8f3232c is a high speed megabit static ram module organized as 32kx32. this module is constructed from four 32kx8 static rams in soj packages on an epoxy laminate (fr4) board. four chip enables (e?-e3) are used to independently enable the four bytes. reading or writing can be executed on individual bytes or any combination of multiple bytes through proper use of selects. the edi8f3232c is offered in both 64 lead simm and 64 pin zip packages, which enables one megabit of memory to be placed in less than 1.2 square inches of board space. all inputs and outputs are ttl compatible and operate from a single 5v supply. fully asynchronous circuitry is used, requiring no clocks or refreshing for operation and providing equal access and cycle times for ease of use. a?-a14 w g e? e1 e2 e3 dq?-dq7 dq8-dq15 dq16-dq23 dq24-dq31 15 8 8 8 8 32kx32 bit cmos static random access memory ? access times 12, 15, 20, and 25ns ? individual byte selects ? output enable function ? fully static, no clocks ? ttl compatible i/o high density packaging ? 64 pin simm, no. 54 ? 64 pin zip, no. 57 ? jedec standard pinout ? common data inputs and outputs single +5v (10%) supply operation zip simm pin names pin names a0-a14 address inputs e?-e3 chip enable w write enable g output enable dq?-dq31 common data input/output vcc power (+5v10%) vss ground nc no connection vss pd2 dq8 dq9 dq10 dq11 a? a1 a2 dq12 dq13 dq14 dq15 vss nc e1 e3 nc g dq24 dq25 dq26 dq27 a3 a4 a5 vcc a6 dq28 dq29 dq30 dq31 pd1 dq? dq1 dq2 dq3 vcc a7 a8 a9 dq4 dq5 dq6 dq7 w a14 e? e2 nc vss dq16 dq17 dq18 dq19 a10 a11 a12 a13 dq20 dq21 dq22 dq23 vss 2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 32 34 36 38 40 42 44 46 48 50 52 54 56 58 60 62 64 1 3 5 7 9 11 13 15 17 19 21 23 25 27 29 31 33 35 37 39 41 43 45 47 49 51 53 55 57 59 61 63 electronic designs incorporated ? one research drive ? westborough, ma 01581usa ? 508-366-5151 ? fax 508-836-4850 ? electronic designs europe ltd. ? shelley house, the avenue ? lightwater, surrey gu18 5rf united kingdom ? 01276 472637 ? fax: 01276 473748 http://www.electronic-designs.com pd1=open pd2 = vss vss pd2 dq8 dq9 dq10 dq11 a? a1 a2 dq12 dq13 dq14 dq15 vss nc e1 e3 nc g dq24 dq25 dq26 dq27 a3 a4 a5 vcc a6 dq28 dq29 dq30 dq31 pd1 dq? dq1 dq2 dq3 vcc a7 a8 a9 dq4 dq5 dq6 dq7 w a14 e? e2 nc vss dq16 dq17 dq18 dq19 a10 a11 a12 a13 dq20 dq21 dq22 dq23 vss 2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 32 34 36 38 40 42 44 46 48 50 52 54 56 58 60 62 64 1 3 5 7 9 11 13 15 17 19 21 23 25 27 29 31 33 35 37 39 41 43 45 47 49 51 53 55 57 59 61 63
