HANBit HMS25632J2 SRAM MODULE 1Mbyte (256K x 32-Bit), 5V, 68-Pin JLCC Design Part No. HMS25632J2 GENERAL DESCRIPTION The HMS25632J2 is a high-speed static random access memory (SRAM) module containing 262,144 words organized in a x32-bit configuration. The module consists of two 256K x 16 SRAMs mounted on a 68-pin, double-sided, FR4-printed circuit board. The HMS25632J2 uses 31 common input and output lines and has an output enable pin which operates faster than address access time at read cycle. Also it allows that lower and upper byte access by data byte control (/BS0~/BS3). 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.
