FLASH-ROM MODULE 16MByte (16M x 8-Bit) , SMM 80Pin
Part No. HMF16M8F8VS
GENERAL DESCRIPTION
The HMF16M8F8VS is a high-speed flash read only memory (FROM) module containing 16,777,216 bytes organized in
an x8bit configuration. The module consists of eight 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.
