HMS51232J4
SRAM MODULE 2Mbyte (512K x 32-Bit), 68-Pin JLCC Packaging
Part No. HMS51232J4
GENERAL DESCRIPTION
The HMS51232J4 is a static random access memory (SRAM) module containing 524,288 words organized in a x32-bit
configuration. The module consists of four 512K x 8 SRAMs mounted on a 68-pin, single-sided, FR4-printed circuit board.
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.
