GENERAL DESCRIPTION
The HMN1288D Nonvolatile SRAM is a 1,048,576-bit static RAM organized as 131,072 bytes by 8 bits.
The HMN1288D 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 HMN1288D 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.
