HMNP16MM
Non-Volatile SRAM MODULE 16Mbyte (4,096K x 32Bit), PCI interface, (SMM) 5V
Part No. HMNP16MM
GENERAL DESCRIPTION
The HMNP16MM Nonvolatile SRAM is a 16,777,216-byte static RAM organized as 8,388,608 words by 16 bits.
The HMNP16MM 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.
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 HMNP16MM uses extremely low standby current CMOS SRAMs, coupled with small lithium coin cells to
provide non-volatility without long write-cycle times and the write-cycle limitations associated with EEPROM.
