HANBit 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.
