HMNP32MM
Non-Volatile SRAM MODULE 32Mbyte (8M x 32Bit), PCI interface, (SMM) 5V
Part No.
HMNP32MM
GENERAL DESCRIPTION
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 V
CC
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
CC
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.
