HMF4M32B8VS
FLASH-ROM MODULE 16MByte (4M x 32-Bit) ,72pin-SODIMM,
3.3V
Part No. HMF4M32B8VS
GENERAL DESCRIPTION
The HMF4M32B8VS is a high-speed flash read only memory (FROM) module containing 4,194,304 words organized in a
x32bit configuration. The module consists of eight 2M x 8 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 other flash or EPROM devices.
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 +3.0V DC power supply.
