SRAM MODULE 8Mbyte(4M x 16-Bit) 80-Pin SMM 5V
Part No.
HMS4M16F16G
HMS4M16F16G
GENERAL DESCRIPTION
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, double-
sided, 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’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.
