HMF1M32M8S

HANBit HMF1M32M8S FLASH-ROM MODULE 4MByte (1M x 32-Bit), 72pin-SIMM, 5V Part No. HMF1M32M8S (Switching for write enable/disable) GENERAL DESCRIPTION The HMF1M32M8S is a high-speed flash read only memory (FROM) module containing 1,048,576 words organized in a x32bit configuration. The module consists of eight 512K x 8 FROM mounted on a 72 -pin, both-sided, FR4-printed circuit board.In order to write control, the HMF1M32M8S provides Write Enable and Write Disable selection by SMT switch. 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 www.DataSheet4U.com device 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 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 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 FEATURES w Access time: 70, 90 and 120ns wSwitching for write enable and disable. w High-density 4MByte design ...
