SST25PF020B 2-Mbit 2.3V-3.6V SPI Serial Flash Features Packages Single Voltage Read and Write Operations: 8-Lead SOIC (150 mils), 8-Contact USON (3 mm x 2 mm) and 8-Contact WSON - 2.3V-3.6V (6 mm x 5 mm) Serial Interface Architecture: - SPI Compatible: Mode 0 and Mode 3 Product Description High-Speed Clock Frequency: The 25 series Serial Flash family features a four-wire, - 80 MHz (2.7V-3.6V operation) SPI compatible interface that allows for a low pin-count - 50 MHz (2.3V-2.7V operation) package which occupies less board space and ulti- Superior Reliability: mately lowers total system costs. The SST25PF020B - Endurance: 100,000 cycles (typical) devices are enhanced with improved operating fre- - Greater than 100 years data retention quency and even lower power consumption. Low-Power Consumption: SST25PF020B SPI serial Flash memories are manu- - Active Read current: 10 mA (typical) factured with proprietary, high-performance CMOS - Standby current: 5 A (typical) SuperFlash technology. The split-gate cell design and thick-oxide tunneling injector attain better reliability and Flexible Erase Capability: manufacturability compared with alternate approaches. - Uniform 4-Kbyte sectors The SST25PF020B devices significantly improve per- - Uniform 32-Kbyte overlay blocks formance and reliability, while lowering power con- - Uniform 64-Kbyte overlay blocks sumption. The devices write (Program or Erase) with a Fast Erase and Byte Program: single power supply of 2.3V-3.6V for SST25PF020B. - Chip Erase time: 35 ms (typical) The total energy consumed is a function of the applied - Sector/Block Erase time: 18 ms (typical) voltage, current and time of application. Since for any given voltage range the SuperFlash technology uses - Byte Program time: 7 s (typical) less current to program and has a shorter erase time, Auto Address Increment (AAI) Programming: the total energy consumed during any erase or pro- - Decrease total chip programming time over gram operation is less than alternative Flash memory Byte Program operations technologies. End-of-Write Detection: See Figure 2-1 for pin assignments. - Software polling the BUSY bit in STATUS register - Busy Status readout on SO pin in AAI Mode Hold Pin (HOLD ): - Suspends a serial sequence to the memory without deselecting the device Write Protection (WP ): - Enables/Disables the Lock-Down function of the STATUS register Software Write Protection: - Write protection through Block Protection bits in STATUS register Temperature Range: - Commercial: 0C to +70C All devices are RoHS compliant 2012-2020 Microchip Technology Inc.
