HMN28D Datasheet (Hanbit Electronics)

HMN28D, Non-Volatile SRAM

The HMN28D are 16,384-bit, fully static, nonvolatile SRAM’s organized as 2,048 bytes by 8 bits.

Each NVSRAM has a self-contained lithium energy source and control circuitry, which constantly monitors Vcc for an out-of-tolerance condition.

When such a condition occurs, the lithium energy source is au
