HMF51232M4D

Stresses greater than those listed under " Absolute Maximum Ratings" may cause permanent damage to the device. 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 extended periods may affect reliability.

The HMF51232M4D is a high-speed flash read only memory (FROM) module containing 524,288 words organized in a x32bit configuration. The module consists of four 512Kx 8 FROM mounted on a 72-pin, single-sided, FR4-printed circuit board. ommands 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 HMF51232M4D is similar to reading from 12.0V flash or EPROM devices.

Four chip enable inputs, (/CE_UU2, /CE_UM2, /CE_LM2, /CE_LL2) are used to enable the module's 4 bytes independently. Output enable (/OE) and write enable (/WE) can set the memory input and output. When FROM module is disable condition, the module HMF51232M4D is becoming power standby mode, system designer can get low-power design.

All module HMF51232M4D components may be powered from a single +5V DC power supply and all inputs and outputs are TTL-compatible.
