SST25VF020B-80-4I-QAE

SST25VF系列 2Mb 256 Kx8 表面贴装 SPI 串行闪存-WSON-8

Product Description

The 25 series Serial Flash family features a four-wire, SPI-compatible interface that allows for a low pin-count package which occupies less board space and ultimately lowers total system costs. The SST25VF020B devices are enhanced with improved operating frequency and even lower power consumption. SST25VF020B SPI serial flash memories are manufactured with SST proprietary, high-performance CMOS SuperFlash technology. The split-gate cell design and thick-oxide tunneling injector attain better reliability and manufacturability compared with alternate approaches.
