HMN1288J
Non-Volatile SRAM MODULE 1Mbit (128K x 8-Bit),34Pin-JLCC, 5V Part No. HMN1288J
GENERAL DESCRIPTION
The HMN1288J Nonvolatile SRAM is a 1,048,576-bit static RAM organized as 131,072 bytes by 8 bits. The HMN1288J 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-oftolerance condition. When such a condition occurs, the lithium energy source is automatically switched on to sustain the memory until after Vcc returns valid and write protection is unconditionally enabled to prevent garbled data.
