BQ4011YMA-200 Description

The BQ4011YMA-200 from Texas Instruments is a 256Kbit (32K x 8) Non-Volatile Static Random-Access Memory (NVSRAM) with a parallel memory interface, designed for applications requiring high-speed, non-volatile data storage. Housed in a 28-pin DIP (Dual In-line Package), this through-hole-mount IC operates within a 4.5V to 5.5V supply range and features a 200ns access time, ensuring rapid read/write operations. With an operating temperature range of 0°C to 70°C, it is suited for industrial and commercial environments. The device combines SRAM's speed with EEPROM's non-volatility, eliminating the need for external backup batteries.
