2 Mbit SPI Serial Flash
A Microchip Technology Company
SST25VF020B
Data Sheet
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 ulti-
mately 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 com-
pared with alternate approaches.
Features

– Byte-Program Time: 7 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 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
