HMF8M16F8VS
FLASH-ROM MODULE 16MByte (8M x 16-Bit) , SMM 80Pin
Part No. HMF8M16F8VS
GENERAL DESCRIPTION
The HMF8M16F8VS is a high-speed flash read only memory (FROM) module containing 8,388,608 words organized in an
x16bit configuration. The module consists of eight 2M x 8 FROM mounted on a 80-pin, MMC 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.
