Image of Microchip Technology's SPI-Compatible Serial SRAM DevicesMicrochip’s serial SRAM family provides a way to easily and inexpensively add external RAM to almost any application. These serial devices use less power and fewer I/O connections than traditional parallel SRAM. Also, they allow designers to use a smaller microcontroller rather than moving to a larger microcontroller just to get more on-board RAM. SPI-compatible serial SRAM devices from Microchip are available in 64 and 256 Kbit options. These devices provide high-speed performance at low power making them ideal for embedded applications needing more RAM. The devices use fewer pins with fewer interface connections and smaller packages thus ensuring smaller designs and lower system costs.

Features
  • Low power CMOS technology: 4 µA max standby current
  • Standard 4-pin SPI interface: chip select, data in, data out, and clock
  • 8-bit status register controls operational modes: byte, page, and sequential
  • 32-byte page
  • High-speed SPI bus with 20 MHz maximum speed
  • Industrial temperatures range: -40°C to +85°C
  • Small, 8-lead SOIC, TSSOP, and PDIP packages
