If you are looking for an easy and inexpensive way to add more RAM to your automotive application, our serial SRAM devices are stand-alone volatile memory solutions that can help you create more compact designs while adding features to your current microcontroller (MCU). These 8-pin low-power, high-performance SRAM devices have unlimited endurance and zero write times, making them ideal for applications involving continuous data transfer, buffering, data logging, audio, video and other math- and data-intensive functions. They are available in densities from 64 Kbit up to 1 Mbit and support Serial Peripheral Interface (SPI), Serial Dual I/O Interface (SDI) and Serial Quad I/O™ (SQI™) bus modes. Our automotive-grade serial SRAM devices are AEC-Q100 qualified and ISO/TS16949 compliant to meet the rigorous quality, reliability and long product lifecycle requirements of automotive designers.

Serial SRAM in 2 Minutes

Key Benefits of Serial SRAM:


  • High-speed serial interface architecture
    • 1-, 2- and 4-bit SPI protocol
  • Low-pin-count interface as compared to traditional parallel SRAM interface
  • Low-cost RAM expansion without costly microcontroller upgrade
  • Low power consumption
