com HANBit HMN5128JV Non-Volatile SRAM MODULE 4Mbit (512K x 8-Bit),34Pin-JLCC, 3.
3V Part No.
HMN5128JV GENERAL DESCRIPTION The HMN5128JV Nonvolatile SRAM is a 4,194,304-bit static RAM organized as 524,288 bytes by 8 bits.
The HMN5128JV 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-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 gar...
