| HANBit HMS2M32M16V/Z16V SRAM MODULE 8Mbyte (2M x 32-Bit), 3.3V 72-Pin SIMM Design Part No. HMS2M32M16V, HMS2M32Z16V GENERAL DESCRIPTION The HMS2M32M16V/Z16V is a high-speed static random access memory (SRAM) module containing 2,097,152 words organized in a x32-bit configuration. The module consists of sixteen 1M x 4 SRAMs mounted on a 72-pin, double-sided, FR4printed circuit board. PD0 to PD3 identify the module's density allowing interchangeable use of alternate density, industry- standard modules. Four chip enable inputs, (/CE1, /CE2, /CE3 and /CE4) are used to enable the module's 4 bytes independently. Output enable (/OE) and write enable (/WE) can set the memory input and output. Data is written into the SRAM memory when write enable (/WE) and chip enable (/CE) inputs are both LOW. accomplished when /WE remains HIGH and /CE and output enable (/OE) are LOW. For reliability, this SRAM module is designed as multiple power and ground pin. All module components may be powered from a single +3.3V DC power supply and all inputs and outputs are fully LVTTL-compatible. Reading is FEATURES w Access times: 10, 12, 15, 17 and 20ns w High-density 8MByte design w High-reliability, high-speed design w Single + 3.3V 10% power supply w Easy memory expansion /CE and /OE functions w All inputs and outputs are LVTTL-compatible w Industry-standard pinout w FR4-PCB design w Low profile 72-pin w Part identification - HMS2M32M16V : SIMM Design, Gold Lead - HMS2M32Z16V: ZIP Design, Solder Pin Lead ( The both are pin-to-pin compatible) PIN 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 -10 -12 -15 -17 -20 M Z 16 17 18 19 20 21 22 23 24 SYMBOL Vcc NC Vss NC Vss NC Vss DQ0 DQ8 DQ1 DQ9 DQ2 DQ10 DQ3 DQ11 Vcc A0 A7 A1 A8 A2 A9 DQ12 DQ4 PIN ASSIGNMENT PIN 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 SYMBOL DQ13 DQ5 DQ14 DQ6 DQ15 DQ7 Vss /WE A15 A14 /CE2 /CE1 /CE4 /CE3 A17 A16 /OE Vss DQ24 DQ16 DQ25 DQ17 DQ26 DQ18 PIN 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 SYMBOL DQ27 DQ19 A3 A10 A4 A11 A5 A12 Vcc A13 A6 DQ20 DQ28 DQ21 DQ29 DQ22 DQ30 DQ23 DQ31 Vss A18 A19 NC Vcc OPTIONS w Timing 10ns access 12ns access 15ns access 17ns access 20ns access w Packages 72-pin SIMM 72-pin ZIP MARKING 72-PIN SIMM TOP VIEW URL: www.hbe.co.kr Rev. 1.0 (September / 2002) 1 HANBit Electronics Co.,Ltd.
