25VF512

A Microchip Technology Company 512 Kbit SPI Serial Flash SST25VF512 Data Sheet SST serial flash family features a four-wire, SPI-compatible interface that allows for a low pin-count package occupying less board space and ultimately lowering total system costs. SST25VF512 SPI serial flash memory is manufactured with SST's proprietary, high-performance CMOS SuperFlash technology. The splitgate cell design and thick-oxide tunneling injector attain better reliability and manufacturability compared with alternate approaches. Features Single 2.7-3.6V Read and Write Operations Serial Interface Architecture – SPI Compatible: Mode 0 and Mode 3 20 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 Fast Erase and Byte-Program: – Chip-Erase Time: 70 ms (typical) – Sector- or Block-Erase Time: 18 ms (typical) – Byte-Program Time: 14 µs (typical) Auto Address Increment (AAI) Programming – Decrease total chip programming time over Byte-Program operations End-of-Write Detection – Software Status 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 ...
