HANBit HAN BIT HMS1M32M8G/Z8 SRAM MODULE 4Mbyte(1M x 32-Bit) Part No. HMS1M32M8G, HMS1M32Z8 GENERAL DESCRIPTION The HMS1M32M8G/Z8 is a high-speed static random access memory (SRAM) module containing 1,048,576 words organized in a x32-bit configuration. The module consists of eight 1M x 4 SRAMs mounted on a 72-pin, double-sided, FR4-printed circuit board. PD0 to PD3 identify the module’s density allowing interchangeable use of alternate density, industry- standard modules. Eight 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 +5V DC power supply and all inputs and outputs are fully TTL-compatible.
