HMF51232M4S
FLASH-ROM MODULE 2MByte (512K x 32-Bit)
Part No. HMF51232M4S
GENERAL DESCRIPTION
The HMF51232M4S 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 +5V DC power supply and all inputs and outputs are TTL-compatible.

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

Byte Programming Time
Chip Programming Time
Notes:
1.
Typical program and erase times assume the follwing conditions:25°,5.0Vcc,1,000,000cycles.
Additionally,programming typicals assume checkerboard pattern.
2.
3.
Under worst case conditions of 90°C, Vcc=4.5V(4.75V for-55), 1,000,000 cycles.
The typical chip programming time is considerably less than the maximum chip programming time listed, since most
bytes program faster than the maximum byte program time listed. If the maximum byte program time given is
exceeded, only then does the device set DQ5= 1. See the section os DQ5for further information.
4.
5.
In the pre-programming step of the Embedded Erase algorithm, all bytes are programmed to 00h before erasure.
System-level overhead is the time required to execute the four-bus-cycle command sequence for programming. See
Table 4 for further in formation on command definitions.
6.
The device has a guaranteed minimum erase and program cycle endurance of 1,000,000cycles.
