FLASH-ROM MODULE 8MByte (8M x 8-Bit) – SMM Packages
Part No. HMF8M8F4V,HMF8M8F4VT
GENERAL DESCRIPTION
The HMF8M8F4V is a high-speed flash read only memory (FROM) module containing 8,388,608 words organized in a x8bit
configuration. The module consists of four 2M x 8 FROM mounted on a 100-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.
Four chips enable inputs, /CS(/CS0, /CS1, /CS2, /CS3) are used to enable the module’s 4 chips independently. 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.
