The SST26VF SQI product family (Microchip Technology) is an automotive-grade NOR Flash with wider voltage and a larger temperature range. Microchip claims to be the only vendor to offer an extended-voltage Serial Quad I/O Flash device in automotive temperature grades.

The SST26VF SQI product family (Microchip Technology) is an automotive-grade NOR Flash with wider voltage and a larger temperature range. Microchip claims to be the only vendor to offer an extended-voltage Serial Quad I/O Flash device in automotive temperature grades.

The family of products, in densities of 16-, 32- and 64- Mbits, operates at Automotive Grade 2 and 3 and extends the operating voltage from 2.7V down to 2.3V and temperature up to 105°C. SST’s proprietary, SuperFlash technology improves performance and reliability, and reduces power consumption for high-bandwidth, compact designs. The SST26VF family consumes 15 mA in typical high-speed operating conditions.

The robustness of the SuperFlash technology memory cell brings high endurance to rewrite cycling and excellent data retention with extremely low failure rate and good performance at high temperatures. All of these features are critical parameters to meet the vigorous requirements for automotive quality and reliability. The product also supports the long life cycle required by the automotive industry.
