HMS12864F8VL
SRAM MODULE 1MByte (128K x 64 bit), 120-Pin SMM, 3.3V
Part No. HMS12864F8VL
GENERAL DESCRIPTION
The HMS12864F8VL is a high-speed static random access memory (SRAM) module containing 131,072 words organized in
a x 64-bit configuration. The module consists of eight 128K x 8 SRAMs mounted on a 120-pin, both-sided, FR4-printed circuit
board.
Byte write enable inputs,(/WE0,/WE1,/WE2,/WE3,/WE4,/WE5,/WE6,/WE7) are used to enable the modules 8 bits
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 TTL-compatible.
