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, double-

sided, 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
