HMF4M32M8G

` Stresses greater than those listed under " Absolute Maximum Ratings" may cause permanent damage to the devic e. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operating section of this specification is not implied. Exposure to absolute maximum rating conditions for extende d periods may affect reliability.

The HMF4M32M8G is a high-speed flash read only memory (FROM) module containing 8,388,608 words organized in a x32bit configuration. The module consists of eight 2M x 8bit FROM mounted on a 72 -pin, double-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 HMF4M32M8G is similar to reading from 12.0V flash or EPROM devices.

Eight chip enable inputs, (/CE_UU1, /CE_UM1, /CE_LM1, /CE_LL1, /CE_UU2, /CE_UM2, /CE_LM2, CE_LL2) are use d to enable the module's 4 bytes independently. Outputs enable (/OE) and write enable (/WE) can set the memory input and
output.When FROM module is disable condition the module HMF4M32M8G is becoming power standby mode, system designer can get low - power design. All module components may be powered from a single +5V DC power supply and all inputs and outputs are
TTL-compatible.
