HMN328D

Non-Volatile SRAM MODULE 256Kbit (32K x 8-Bit),28Pin DIP, 5V

Part No. HMN328D

GENERAL DESCRIPTION

The HMN328D nonvolatile SRAM is a 262,144-bit static RAM organized as 32,768 bytes by 8 bits.

The HMN328D 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

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

returns valid.

The HMN328D 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.
