HMF1M32M4GL
FLASH-ROM MODULE 4MByte (1M x 32-Bit),72pin-SIMM, 5V
Part No. HMF1M32M4GL
GENERAL DESCRIPTION
The HMF1M32M4GL is a high-speed flash read only memory (FROM) module containing 1,048,576 words organized in a
x32bit configuration. The module consists of four 1M x 8 FROM mounted on a 72 -pin, single-sided, FR4-printed circuit board.
The HMF1M32M4GL is entirely pin and command set compatible with JEDEC single-power-supply flash standard.
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
www.DataSheet4U.dceomvice 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 8bits 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 standb y 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.
