SST25VF040B-50-4C-S2AF集成电路（IC）的存储器规格书PDF中文资料

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.

• Fast Erase and Byte-Program:

– Chip-Erase Time: 35 ms (typical)

– Sector-/Block-Erase Time: 18 ms (typical)

– 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
