HMS2M32M16V/Z16V
SRAM MODULE 8Mbyte (2M x 32-Bit), 3.3V 72-Pin SIMM Design
Part No. HMS2M32M16V, HMS2M32Z16V
GENERAL DESCRIPTION
The HMS2M32M16V/Z16V is a high-speed static random access memory (SRAM) module containing 2,097,152 words
organized in a x32-bit configuration. The module consists of sixteen 1M x 4 SRAMs mounted on a 72-pin, double-sided, FR4printed circuit board.
PD0 to PD3 identify the module’s density allowing interchangeable use of alternate density, industry- standard modules. 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.
