HMS4M16F16G

Stresses greater than those listed under " Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operating section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.

The HMS4M16F16G is a high-speed static random access memory (SRAM) module containing 4,194,304 words organized in a x16-bit configuration. The module consists of sixteen 1M x 4 SRAMs in TSOP package is mounted on a 80-pin, doublesided, FR4-printed circuit board. The HMS4M16F16 is a SMM(Stackable Memory Module) designed and is intended for mounting into two 40-pin connector sockets.

Two decoders are used to select chips and used to enable the module HMS4M16F16G'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 HMS4M16F16G 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.
