PRODUCT DESCRIPTION

The 25 series Serial Flash family features a four-wire, SPI compatible interface that allows for a low pin-count pack age which occupies less board space and ultimately lowers total system costs. The SST25VF040B devices are enhanced with improved operating frequency and even lower power consumption.

– Byte-Program Time: 7 μs (typical)

? Auto Address Increment (AAI) Programming

– Decrease total chip programming time over

Byte-Program operations

? End-of-Write Detection

– Software polling the BUSY bit in Status Register
