HMF51232M4V
FLASH-ROM MODULE 2MByte (512K x 32-Bit)
Part No. HMF51232M4V
GENERAL DESCRIPTION
The HMF51232M4V 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_UU1, /CE_UM1, /CE_LM1, /CE_LL1) 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 +3V DC power supply and all inputs and outputs are TTL-compatible.

ERASE AND PROGRAMMING PERFORMANCE
PARAMETER
Sector Erase Time
Chip Erase Time
Byte Programming Time
Chip Programming Time
Notes:
1. Typical program and erase times assume the following conditions:25° C, 3.0V Vcc, 1,000,000 cycles. Additionally,
programming typicals assume checkerboard pattern.
2. Under worst case conditions of 90°C, Vcc=2.7V(3.0V for-55R), 1,000,000cycles.
3. The typical chip programming time is considerably less than the maximum chip programming time listed, since most
bytes program faster than the maximum program times listed.
4. In the pre-programming step of th Embedded Erase algorithm, all bytes are programmed to 00h before erasure.
5. System-level overhead is the time required to execute the two- or four-bus-cycle sequence for the program command.
See Table 4 for further information on command definitions.
6. The device has a minimum guaranteed erase and program cycle endurance of 1,000,000 cycles.
