Microchip SST26LF064RT 64-Mbit Radiation Tolerant

The SST26LF064RT is a Radiation Tolerant Serial Quad I/O™ (SQI™) flash device using 4-bit multiplexed I/O serial interface to boost performance while maintaining the compact form factor of standard serial flash devices.

SST26LF064RT also support full command-set compatibility to traditional Serial Peripheral Interface (SPI) protocol. Operating at frequencies of 80 MHz, the SST26LF064RT enables minimum latency execute-in-place (XIP) capability without the need for code shadowing on an SRAM.

The device’s high performance and reliability make it the ideal choice for Space and Hirel applications. Further benefits are achieved with SST’s proprietary, high-performance CMOS SuperFlash® technology, which significantly improves performance and reliability, and lowers power consumption for high bandwidth, compact designs.

The SST26LF064RT default at power up is with WP# and HOLD pins enable and SIO2 and SIO3 pins disable allowing for SPI protocol operations without register configuration.
