ACCUTEK AK63232Z 32,768 x 32 Bit CMOS / BiCMOS Static Random Access Memory MICROCIRCUIT CORPORATION DESCRIPTION The Accutek AK63232Z SRAM Module consists of fast high performance SRAMs mounted on a low profile, 64 pin ZIP Board. The module utilizes four 28 pin 32K x 8 SRAMs in 300 mil SOJ packages and four decoupling capacitors mounted on the front side of a printed circuit board. Top View 64-Pin ZIP The SRAMs used have common I/O functions and single output enable functions. Also, four separate chip select (CE) connections are used to independently enable the four bytes. The modules can be supplied in a variety of access time values from 8 nSEC to 45 nSEC in CMOS or BiCMOS technology. 1 33 32 64 The Accutek module is designed to have a maximum seated height of 0.500 inch. The module conforms to JEDEC-standard sizes and pin-out configurations. This, along with use of two pins for module memory density identification, PD 0 and PD 1 , minimizes interchangeability and design considerations when changing from one module size to the other in customer applications. · Upward compatible with 64K x 32 (AK63264), 256K x 32 (AK632256), 512K x 32 (AK632512) and 1 Meg x 32 (AK6321024) FEATURES · Presence Detect, PD0 and PD1 for identifying module density · Fast Access Times range from 8 nSEC BiCMOS to 45 nSEC CMOS · 32,768 x 32 bit organization · JEDEC standard 64 pin ZIP format · TTL compatible inputs and outputs · Common I/O, single OE functions with four separate chip selects (CE) · Single 5 volt power supply - AK63232Z · Single 3.3 volt power supply - AK63232Z/3.3 · Low height, 0.500 inch maximum seated height PIN NOMENCLATURE · Operating temperature range in free air, 00C to 700C PIN ASSIGNMENT FUNCTIONAL DIAGRAM PIN # SYMBOL PIN # SYMBOL PIN # SYMBOL PIN # SYMBOL 1 Vss 17 A2 33 CE4 49 A4 Chip Enable 2 PD0 18 A9 34 CE3 50 A11 DQ1 - DQ32 Data In/Data Out 3 PD1 19 DQ13 35 NC 51 A5 OE Output Enable 4 DQ1 20 DQ5 36 NC 52 A12 PD0 - PD1 Presence Detect Vcc A0 - A14 Address Inputs CE1 - CE4 A0 - A14 15 AOA14 OE OE WE WE CE DQ9 21 DQ14 37 OE 53 Vcc 6 DQ2 22 DQ6 38 Vss 54 A13 Power Supply 7 DQ10 23 DQ15 39 DQ25 55 A6 OE Vss Ground 8 DQ3 24 DQ7 40 DQ17 56 DQ21 WE WE Write Enable Leaded ZIP: AK63232Z DQ1 DQ2 DQ3 DQ4 DQ5 DQ6 DQ7 DQ8 CE1 5 MODULE OPTIONS DQ1 DQ2 DQ3 DQ4 DQ5 DQ6 DQ7 DQ8 9 DQ11 25 DQ16 41 DQ26 57 DQ29 10 DQ4 26 DQ8 42 DQ18 58 DQ22 11 DQ12 27 Vss 43 DQ27 59 DQ30 12 Vcc 28 WE 44 DQ19 60 DQ23 13 A0 29 NC 45 DQ28 61 DQ31 14 A7 30 A14 46 DQ20 62 DQ24 15 A1 31 CE2 47 A3 63 DQ32 16 A8 32 CE1 48 A10 64 Vss AODQ1 A14 DQ2 DQ3 DQ4 DQ5 DQ6 DQ7 DQ8 DQ9 DQ10 DQ11 DQ12 DQ13 DQ14 DQ15 DQ16 CE CE2 AODQ1 A14 DQ2 DQ3 DQ4 DQ5 DQ6 DQ7 DQ8 OE WE DQ17 DQ18 DQ19 DQ20 DQ21 DQ22 DQ23 DQ24 CE CE3 AO- DQ1 A14 PD0 = Open PD1 = Open OE WE DQ2 DQ3 DQ4 DQ5 DQ6 DQ7 DQ8 CE CE4 DQ25 DQ26 DQ27 DQ28 DQ29 DQ30 DQ31 DQ32 MECHANICAL DIMENSIONS ORDERING INFORMATION PART NUMBER CODING INTERPRETATION Position 1 2 3 4 5 6 7 8 Top View ZIP Product 1 1 Inches 2 3 AK = Accutek Memory 4 Type 3 4 = Dynamic RAM 5 = CMOS Dynamic RAM 6 = Static RAM Organization/Word Width 4 1 = by 1 16 = by 16 4 = by 4 32 = by 32 8 = by 8 36 = by 36 9 = by 9 Size/Bits Depth 5 64 = 64K 256 = 256K 1024 = 1 MEG Package Type 6 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) Special Designation 7 P = Page Mode N = Nibble Mode K = Static Column Mode W = Write Per Bit Mode V = Video Ram Separator 6 59 60 61 62 63 64 0.500 MAX 4 MEG 8 MEG 16 MEG .100 x .100 ANGLE NOTCH 0.125 0.155 4096 = 8192 = 16384 = 1 C L 0.125 0.135 CLCL 32 0.050 TYP 3.590 3.610 33 0.100 TYP - = Commercial 00C to +700C M = Military Equivalent Screened (-550C to +1250C) I = Industrial Temperature Tested (-450C to +850C) X = Burned In 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 CL CL 8 5 2 64 0.100 TYP The numbers and coding on this page do not include all variations available but are shown as examples of the most widely used variations.
