HMF4M32M8G
FLASH-ROM MODULE 16MByte (4M x 32Bit), 72-Pin SIMM, 5V
Part No. HMF4M32M8G
GENERAL DESCRIPTION
The HMF4M32M8G is a high-speed flash read only memory (FROM) module containing 8,388,608 words organized in a
x32bit configuration. The module consists of eight 2M x 8bit FROM mounted on a 72 -pin, double-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.
Eight chip enable inputs, (/CE_UU1, /CE_UM1, /CE_LM1, /CE_LL1, /CE_UU2, /CE_UM2, /CE_LM2, CE_LL2) are use d to
www.DataSheet4U.ecnomable the module’s 4 bytes independently. Outputs 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 +5V DC power supply and all inputs and outputs are
TTL-compatible.
