HANBit HMS51232J4V HAN SRAM MODULE 2Mbyte (512Kx32Bit), 68-Pin JLCC Packaging,3.3V BIT Part No. HMS51232J4V GENERAL DESCRIPTION The HMS51232J4V 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, FR4printed 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 +3.3V DC power supply and all inputs and outputs are fully LVTTL-compatible..
