The BQ4011 from Texas Instruments is a 262,144-bit nonvolatile static RAM, organized as 32,768 words by 8 bits. It provides reliable nonvolatility with unlimited write cycles, similar to conventional SRAM. The device features automatic write-protection during power-up and power-down cycles, ensuring data integrity.
Key specifications include a minimum data retention of 10 years in the absence of power and a maximum access time of 70 ns. It operates from a single 5V supply with a negative supply tolerance of -5% or -10% depending on the variant. The BQ4011 is designed for industry-standard 28-pin pinouts and is socket-compatible with standard SRAMs, EPROMs, and EEPROMs.
This nonvolatile SRAM is suitable for applications requiring data persistence without the write-cycle limitations of EEPROMs. Its integrated control circuitry and lithium energy source provide a robust solution for data storage in systems where power loss is a concern. The device is available in a 28-pin SOIC surface-mount package.
