25WF040B-40I/SN


The SST25WF040B is a member of the Serial Flash 25 Series family and features a four-wire SPI-compatible interface that allows for a low pin-count package which occupies less board space and ultimately lowers total system costs. SPI serial flash memory is manufactured with proprietary, high-performance CMOS SuperFlash technology. The split-gate cell design and thick-oxide tunnelling injector attain better reliability and manufacturability compared with alternate approaches.

• Single voltage read and write operations — 1.65 - 1.95 V
• Serial interface architecture — SPI compatible: Mode 0 and Mode 3
• High speed clock frequency up to 40 MHz
• Dual input/output support — fast-read dual-output instruction (3BH) — fast-read dual I/O instruction (BBH)
• Superior reliability — endurance: 100,000 cycles — data retention of more than 20 years
• Ultra-low power consumption — active read current: 4 mA (typically) — standby current: 10 μA (typically) — power-down mode standby current: 4 μA (typically)
• Flexible erase capability — uniform 4-kByte sectors — uniform 64-kByte overlay blocks
• Page program mode up to 256 bytes/page
• End-of-write detection with software polling the BUSY bit in status register
• Hold pin (HOLD#) to suspend a serial sequence without deselecting the device
• Software write protection — write protection through block protection bits in status register
• Temperature range: -40°C to +85°C
• Packages available — 8-lead SOIC (150 mils) — 8-contact USON (2 mm x 3 mm)
• All devices are RoHS-compliant
