HMN1288D

Non-Volatile SRAM MODULE 1Mbit (128K x 8-Bit), 32Pin-DIP, 5V

Part No. HMN1288D

GENERAL DESCRIPTION

The HMN1288D Nonvolatile SRAM is a 1,048,576-bit static RAM organized as 131,072 bytes by 8 bits.

The HMN1288D has a self-contained lithium energy source provide reliable non-volatility coupled with the unlimited write

cycles of standard SRAM and integral control circuitry, which constantly monitors the single 5V, supply for an out-of-

tolerance condition. When such a condition occurs, the lithium energy source is automatically switched on to sustain the

memory until after V_CCreturns valid and write protection is unconditionally enabled to prevent garbled data. In addition the

SRAM is unconditionally write-protected to prevent an inadvertent write operation. At this time the integral energy source is

switched on to sustain the memory until after V_CCreturns valid.

The HMN1288D uses extremely low standby current CMOS SRAM’s, coupled with small lithium coin cells to provide non-

volatility without long write-cycle times and the write-cycle limitations associated with EEPROM.
