Flash-ROM Module 8MByte (2Mx32Bit), 72Pin-SIMM, 3.3V Design
Part No. HMF2M32M4VGL
GENERAL DESCRIPTION
The HMF2M32M4VGL 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 2M 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.
Register contents serve as input to an internal state-machine, which controls the erase and programming circuitry. Write
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, (/WE0, /WE1, /WE2, /WE3) 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.
