AK61664Z 16,384 x 16 Bit CMOS/BiCMOS Static Random Access Memory ACCUTEK MICROCIRCUIT CORPORATION DESCRIPTION Front View The Accutek AK61664 SRAM Module consists of fast high performance SRAMs mounted on a low profile 40 pin ZIP PCB. The module utilizes two 28 pin 64K x 4 SRAMs in 300 mil SOJ packages and two decoupling capacitor chips mounted on each side of a printed circuit board. 40-Pin ZIP The SRAMs are interconnected on the module to have common I/O functions, single output enable functions and common chip select. The modules can be supplied in a variety of access time values from 8 nSEC to 45 nSEC in CMOS or BiCMOS technology. The Accutek module is designed for the lowest height off the board, consistent with the availability of commonly available SRAM SOJ package configurations. 1 40 FEATURES · 16,384 x 32 SRAM module in high density configuration · 40 pin ZIP format · Common I/O, single OE functions and common chip select CE Function · Low height 0.500 inch ZIP maximum · Fast Access Times range from 12 nSEC to 45 nSEC, CMOS or BiCMOS · TTL compatible inputs and outputs PIN NOMENCLATURE A0 - A15 Address Inputs WE Write Enable OE Output Enable CE Chip Select DQ1 - DQ16 Data In/Data Out Vcc 5v Supply Vss NC · Single 5 volt power supply - AK61664Z · Single 3.3 volt power supply - AK61664Z/3.3 · Operating temperature range in free air, 00C to 700C · Power (Typical) CMOS 3.2 Watt Active 1.2 Watt Standby PIN ASSIGNMENT FUNCTIONAL DIAGRAM PIN # SYMBOL PIN # SYMBOL 1 DQ16 21 A11 2 Vss 22 A4 3 DQ15 23 A10 4 DQ1 24 A5 5 DQ14 25 A9 6 DQ2 26 A6 7 DQ13 27 A8 Ground 8 DQ3 28 A7 No Connect 9 Vss 29 DQ12 10 DQ4 30 DQ5 11 A15 31 DQ11 12 A0 32 DQ6 13 A14 33 Vss 14 A1 34 DQ7 15 A13 35 DQ10 16 A2 36 DQ8 17 A12 37 DQ9 18 A3 38 OE 19 Vcc 39 CE 20 Vss 40 WE MODULE OPTIONS Leaded ZIP: AK61664Z Single In-Line Package BiCMOS 4.8 Watt Active 1.3 Watt Standby MECHANICAL DIMENSIONS ORDERING INFORMATION PART NUMBER CODING INTERPRETATION Position Inches 1 2 3 4 5 6 7 8 0.125 0.155 0.500 MAX 1 C L 0.120 0.130 2.100 MAX CLCL 0.050 TYP 0.100 TYP Product AK = Accutek Memory 2 Type 4 = Dynamic RAM 5 = CMOS Dynamic RAM 6 = Static RAM 3 Organization/Word Width 1 = by 1 16 = by 16 4 = by 4 32 = by 32 8 = by 8 36 = by 36 9 = by 9 4 Size/Bits Depth 64 = 64K 4096 = 4 MEG 256 = 256K 8192 = 8 MEG 1024 = 1 MEG 16384 = 16 MEG 5 Package Type G = Single In-Line Package (SIP) S = Single In-Line Module (SIM) D = Dual In-Line Package (DIP) W = .050 inch Pitch Edge Connect Z = Zig-Zag In-Line Package (ZIP) 6 Special Designation P = Page Mode N = Nibble Mode K = Static Column Mode W = Write Per Bit Mode V = Video Ram 7 Separator - = Commercial 00C to +700C M = Military Equivalent Screened (-550C to +1250C) I = Industrial Temperature Tested (-450C to +850C) X = Burned In 8 Speed (first two significant digits) DRAMS SRAMS 50 = 50 nS 8 = 8 nS 60 = 60 nS 12 = 12 nS 70 = 70 nS 15 = 15 nS 80 = 80 nS 20 = 20 nS The numbers and coding on this page do not include all variations available but are shown as examples of the most widely used variations.
