HMF8M8F4VS

FLASH-ROM MODULE 8MByte (8M x 8-Bit) , SMM 80Pin

Part No. HMF8M8F4VS

GENERAL DESCRIPTION

The HMF8M8F4VS is a high-speed flash read only memory (FROM) module containing 8,388,608 bytes organized in an x8bit

configuration. The module consists of four 2M x 8 FROM mounted on a 80-pin, SMM connector 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.

Output enable (/OE) and write enable (/WE) can set the memory input and output. The host system can detect a program or

erase operation is complete by observing the Ready Pin, or reading the DQ7(Data # Polling) and DQ6(Toggle) status bits.

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 +3V DC power supply and all inputs and outputs are LVTTL-

compatible.
