HMS1M32Z8S

HANBit HMS1M32M8S HAN BIT High-Speed SRAM MODULE 4Mbyte(1M x 32-Bit) Part No. HMS1M32M8S, HMS1M32Z8S GENERAL DESCRIPTION The HMS1M32M8S is a high-speed static random access memory (SRAM) module containing 1,048,576 words organized in a x32-bit configuration. The module consists of eight 512K x 8 SRAMs mounted on a 72-pin, doublesided, FR4-printed circuit board. The HMS1M32M8S also support low data retention voltage for battery back-up operations with low data retention current. Eight chip enable inputs, (/CE_UU1, /CE_UM1, /CE_LM1, /CE_LL1, /CE_UU2, /CE_UM2, /CE_LM2, /CE_LL2) 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. Reading is 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 +5V DC power supply and all inputs and outputs are fully TTL-compatible FEATURES Š Part identification - HMS1M32M8S : SIMM design - HMS1M32Z8S : ZIP design Pin-Compatible with the HMS1M32M8S Vss A3 A2 A1 A0 Vcc A11 /OE A10 Vcc /CE_LL2 /CE_LL1 DQ7 DQ0 DQ1 DQ2 DQ6 DQ5 DQ4 DQ3 A15 A17 /WE A13 Vcc DQ8 DQ9 DQ10 /CE_LM2 Vcc /CE_LM1 DQ15 DQ14 DQ13 DQ12 DQ11 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 PIN...
