www.DataSheet4U.com HANBit HMN5128DV Non-Volatile SRAM MODULE 4Mbit (512K x 8-Bit),32Pin-DIP, 3.3V Part No. HMN5128DV GENERAL DESCRIPTION The HMN5128DV Nonvolatile SRAM is a 4,194,304-bit static RAM organized as 524,288 bytes by 8 bits. The HMN5128DV 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 garbled data.
