GENERAL DESCRIPTION

The HMS25632M8G/Z8 is a high-speed static random access memory (SRAM) module containing 262,144

words organized in a x32-bit configuration. The module consists of eight 256K x 4 SRAMs mounted on a 64-pin,

double-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 +5V DC power supply and all inputs and outputs are fully TTL-compatible.
