PRODUCT DESCRIPTION
SST’s serial flash family features a four-wire, SPI-com patible interface that allows for a low pin-count package occupying less board space and ultimately lowering total system costs. SST25LF020A/040A SPI serial flash memories are manufactured with SST’s 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.

FEATURES:
• Single 3.0-3.6V Read and Write Operations
• Serial Interface Architecture
    – SPI Compatible: Mode 0 and Mode 3
• 33 MHz Max Clock Frequency
• Superior Reliability
    – Endurance: 100,000 Cycles (typical)
    – Greater than 100 years Data Retention
• Low Power Consumption:
    – Active Read Current: 7 mA (typical)
    – Standby Current: 8 µA (typical)
• Flexible Erase Capability
    – Uniform 4 KByte sectors
    – Uniform 32 KByte overlay blocks
