HMS12864F8V
DESCRIPTION
The HMS12864F8V 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 four 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 module’s 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. acplished 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 ponents may be powered from a single +3.3V DC power supply and all inputs and outputs are fully TTL-patible.
