HMNP16MM

The HMNP16MM Nonvolatile SRAM is a 16,777,216-byte static RAM organized as 8,388,608 words by 16 bits. The P16MM has a self-contained lithium energy source provide reliable non-volatility coupled with the unlimited write cycles of dard SRAM and integral control circuitry which constantly monitors the single 5V supply for an out-of-tolerance condition. hen such a condition occurs, the lithium energy source is automatically switched on to sustain the memory until after V _CC s 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 egral energy source is switched on to sustain the memory until after V _CC returns valid. The HMNP16MM 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.
