GENERAL DESCRIPTION
The HMN2568D Nonvolatile SRAM is a 2,097,152-bit static RAM organized as 262,144 bytes by 8 bits. The HMN2568D 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-oftolerance 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 HMN2568D uses extremely low standby current CMOS SRAM’s, coupled with small lithium coin cells to provide nonvolatility without long write-cycle times and the write-cycle limitations associated with EEPROM.

♦ Industry-standard 32-pin 256K x 8 pinout
♦ Unlimited write cycles
♦ Data retention in the absence of VCC
♦ 10-years minimum data retention in absence of power
♦ Automatic write-protection during power-up/power-down cycles
♦ Data is automatically protected during power loss
♦ Conventional SRAM operation; unlimited write cycles
