GENERAL DESCRIPTION

The HMS1M32M8V 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 1M x 4 SRAMs mounted on a 72-pin, double-

sided, FR4-printed circuit board.

PD0 to PD3 identify the module’s density allowing interchangeable use of alternate density, industry- standard

modules. Eight 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 LVTTL-compatible.
