HMF1M32F8
Flash-ROM Module 4MByte (1Mx32Bit), 100Pin-MMC, 5.5V Design
Part No. HMF1M32F8
GENERAL DESCRIPTION
The HMF1M32F8 is a high-speed flash read only memory (FROM) module containing 1,048,576 words organized in a
x32bit configuration. The module consists of eight 512K x 8 FROM mounted on a 100-pin stackable type, 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 used to
enable the module’s 4 bytes 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 +5V DC power supply and all inputs and outputs are TTL -
compatible.
