HMN1288DV

Non-Volatile SRAM Module 1Mbit (128K x 8-Bit), 32Pin-DIP, 3.3V

Part No. HMN1288DV

GENERAL DESCRIPTION

The HMN1288DV Nonvolatile SRAM is a 1,048,576-bit static RAM organized as 131,072 bytes by 8 bits.

The HMN1288DV 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 3.3V, 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 HMN1288DV 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.
