GENERAL DESCRIPTION
The HMS2M32M16G 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, FR4-printed 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.
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.
