REV.02(August,2002) 1 GENERAL DESCRIPTION The HMF3M32M6VA is a high-speed flash read only memory (FROM) module containing 6,291,456 words organized in a x32bit configuration. The module consists of six 1M x 16 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.
