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-of-

tolerance 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. 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 HMN5128DV 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.
