HMF1M32M4V

Flash-ROM Module 4MByte (1Mx32Bit), 72Pin-SIMM, 3.3V Design

Part No. HMF1M32M4V

GENERAL DESCRIPTION

The HMF1M32M4V is a high-speed flash read only memory (FROM) module containing 2,097,152 words organized in a

x32bit configuration. The module consists of four 1M x 8bit FROM mounted on a 72-pin, single -sided, FR4-printed circuit

board.

Commands are written to the command register using standard microprocessor write timings.

cycles also internally latch addresses and data needed for the programming and erase operations. Reading data out of the

device is similar to reading from 12.0V flash or EPROM devices.

Four chip enable inputs, (/CE_1L, /CE_1H) are used to enable the module’s 8 bits independently. Output enable (/OE) and

write enable (/WE) can set the memory input and output.

When FROM module is disable condition the module is becoming power standby mode, system designer can get low -power

design. All module components may be powered from a single + 3.3V DC power supply and all inputs and outputs are TTL-

compatible.
