HMF51232M4D

HANBit HMF51232M4D FLASH-ROM MODULE 2MByte (512K x 32-Bit) Part No. HMF51232M4D GENERAL DESCRIPTION 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. 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 chip enable inputs, (/CE_UU2, /CE_UM2, /CE_LM2, /CE_LL2) are used to enable the module’s 4 bytes independently. www.DataSheet4U.com 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 +5V DC power supply and all inputs and outputs are TTL-compatible.
