HMF8M32M8GL
FLASH-ROM MODULE 32MByte (8M x 32-Bit)
Part No. HMF8M32M8GL
GENERAL DESCRIPTION
The HMF8M32M8GL 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 4M 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 is
similar to reading from 12.0V flash or EPROM devices. This module is 2 bank organized, each bank containing 4Mx32bit, Bank
selection is selected by Bank-E0, Bank-E1 inputs. Byte write enable inputs, (/WE0, /WE1, /WE2, /WE3) are used to enable the
module’s 8bits 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.
