HMF6M32M6V
FLASH-ROM MODULE 24MByte (6M x 32-Bit) ,72pin-SIMM, 3.0V
Part No. HMF6M32M6V
GENERAL DESCRIPTION
The HMF6M32M6V is a high-speed flash read only memory (FROM) module containing 12,582,912 words organized in a
x32bit configuration. The module consists of six 2M x 16 FROM mounted on a 72-pin, both-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 address es 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.
