SST 25VF040B :: SPI serial flash, 2.7 V, 4 Mbit, USON-8

Item-No.: SST 25VF040B
Category of goods: 1

SST 25VF040B

The 25 series Serial Flash family features a four-wire, SPI-compatible interface that allows for a low pin-count package that occupies less board space and ultimately lowers total system costs. SST25VF040B devices are enhanced with improved operating frequency for lower power consumption. SST25VF040B SPI serial Flash memories are manufactured with SST-proprietary, high-performance CMOS SuperFlash technology. The split-gate cell design and thick-oxide tunnelling injector attain better reliability and manufacturability compared to alternative approaches.

Serial interface architecture:
• SPI compatible: Mode 0 and Mode 3
• Supports 50-MHz SPI clock
Low power consumption:
• Active-read current: 10 mA (typical)
• Program and erase current: 30 mA (max)
• Standby current: 5 µA (typical)
Flexible erase capability:
• Uniform 4-kB sectors
• Uniform 32-kB and 64-kB overlay blocks
Fast erase and byte program:
• Chip-erase time: 35 ms (typical)
• Sector-/block-erase time: 18 ms (typical)
• Byte-program time: 7 µs (typical)
Address auto-increment (AAI) programming:
• Decrease total chip-programming time overbyte-program operations
