HMN28D - Non-Volatile SRAM

Description

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.

Features

  • w Access time : 70, 85, 120 and 150ns w High-density design : 2KByte Design w Battery internally isolated until power is applied w JEDEC standard 24-pin DIP Package w Low-power CMOS w Unlimited writes cycles w Data retention in the absence of VCC w 10-years minimum data retention in absence of power w Automatic write-protection during power-up/power-down cycles w Data is automatically protected during power loss w Conventional SRAM operation; unlimited write cycles PIN.

www.DataSheet4U.com HANBit HMN28D Non-Volatile SRAM MODULE 16Kbit (2K x 8-Bit), 24pin DIP, 5V Part No. HMN28D GENERAL DESCRIPTION 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 automatically switched on and writes protection is unconditionally enabled to prevent data corruption. The HMN28D devices can be used in place of existing 2K x 8 SRAM’s directly conforming to the popular byte wide 24-pin DIP standard.
