DS20005016C 11/14 EOL Data Sheet www.microchip.com Features • Single Voltage Read and Write Operations – 1.65-1.95V • Serial Interface Architecture – SPI Compatible: Mode 0 and Mode 3 • High Speed Clock Frequency – 40MHz • Superior Reliability – Endurance: 100,000 Cycles – Greater than 100 years Data Retention • Ultra-Low Power Consumption: – Active Read Current: 2 mA (typical @ 20MHz) – Standby Current: 2 µA (typical) • Flexible Erase Capability – Uniform 4 KByte sectors – Uniform 32 KByte overlay blocks – Uniform 64 KByte overlay blocks (2 Mbit and 4 Mbit only) • Fast Erase and Byte-Program: – Chip-Erase Time: 125 ms (typical) – Sector-/Block-Erase Time: 62ms (typical) – Byte-Program Time: 50 µS (typical) • Auto Address Increment (AAI) Programming – Decrease total chip programming time over Byte-Pro- gram operations • End-of-Write Detection – Software polling the BUSY bit in Status Register – Busy Status readout on SO pin • Reset Pin (RST#) or Programmable Hold Pin (HOLD#) option – Hardware Reset pin as default – Hold pin option to suspend a serial sequence 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 – Industrial: -40°C to +85°C • Packages Available – 8-lead SOIC (150 mils) – 8-contact WSON (5mm x 6mm) • All devices are RoHS compliant SST25WF512 / SST25WF010 / SST25WF020 / SST25WF040 are members of the Serial Flash 25 Series family and feature a four-wire, SPI-compatible interface that allows for a low pin-count package which occupies less board space and ulti- mately lowers total system costs. SPI serial flash memory is manufactured with SST proprietary, high performance CMOS SuperFlash technology. The split-gate cell design and thick-oxide tunneling injector attain better reliability and manufac- turability compared with alternate approaches.
