Hanbit Electronics HMNP32MM

The HMNP32MM Nonvolatile SRAM is a 33,554,432-byte static RAM organized as 16,777,216 words by 16 bits. The HMNP32MM 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-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.

GENERAL DESCRIPTION

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 VCC returns valid. The HMNP32MM 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.
