HMS12832M4V

SRAM MODULE 512KByte (128K x 32-Bit) 3.3V, 64Pin-SIMM

Part No. HMS12832M4V

GENERAL DESCRIPTION

The HMS12832M4V is a high-speed static random access memory (SRAM) module containing 131,072 words organized in

a x32-bit configuration. The module consists of four 128K x 8 SRAMs mounted on a 64-pin, single-sided, FR4-printed circuit

board.

PD0 and PD1 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. 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 +3.3V DC power supply and all inputs and outputs are fully TTL-compatible.
