Product details
Overview
SST25WF080BT-40E/SN from Microchip Technology is an 8 Mbit, 1.65–1.95V SPI serial flash memory IC with dual I/O support, 40 MHz high-speed read capability, and AEC-Q100 qualification for automotive applications. It implements SuperFlash technology with uniform 4 KByte sectors and 64 KByte overlay blocks, enabling reliable firmware storage in space-constrained embedded systems.
For engineers reviewing the SST25WF080BT-40E/SN datasheet, SST25WF080BT-40E/SN pinout, SST25WF080BT-40E/SN application, or SST25WF080BT-40E/SN equivalent, key selection criteria include its industrial/extended temperature range (–40°C to +125°C), deep power-down current of 2 µA, software/hardware write protection, and Fast-Read Dual I/O (BBH) instruction support for bandwidth-critical boot code retrieval.
Technical Context
The SST25WF080BT-40E/SN uses a split-gate SuperFlash cell architecture with thick-oxide tunneling injector, delivering 100,000 program/erase cycles and >20 years data retention. Its SPI interface supports Mode 0 and Mode 3 timing, with dedicated HOLD# and WP# pins enabling suspend-on-demand and lock-down status register protection.
It implements four distinct read modes - standard Read (03H, 30 MHz), High-Speed Read (0BH, 40 MHz), Fast-Read Dual-Output (3BH), and Fast-Read Dual I/O (BBH) - all operating from a single 1.65–1.95V supply. Page programming occurs in 256-byte increments with 0.8 ms typical time, while sector, block, and chip erase times are 40 ms, 80 ms, and 500 ms respectively.

Pinout & Package
Package: 8-contact USON (2 mm × 3 mm, 0.5 mm pitch), RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CE# | Chip Enable | Active-low device select; must remain low during full command sequence including address/data transfer |

IC Role / Device Role / Timing Role: Secure, tamper-resistant firmware storage with deep power-down (2 µA) to maximize battery runtime between charges. Use Value: Single 1.8V supply simplifies power design; software block protection (BP0–BP2) isolates bootloader region from application updates. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar serial flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Winbond W25Q80DVSSIG | 8 Mbit, 1.65–1.95V, 104 MHz Quad SPI; no Dual I/O support; 3 mm × 4 mm SOIC-8 only | Lacks HOLD#/WP# pin-level control granularity; requires Quad SPI host interface | Select if higher read bandwidth (104 MHz) and quad interface are available; not drop-in compatible due to pin count and protocol differences |
| Cypress S25FL008K0XMFI010 | 8 Mbit, 2.7–3.6V supply; supports 80 MHz DDR read; 2 mm × 3 mm USON available but rated only to +85°C | Higher voltage requirement necessitates level-shifting; lacks AEC-Q100 qualification and extended temperature rating | Choose for industrial applications where 3.3V supply is standard and automotive qualification is unnecessary |
Compared with W25Q80DVSSIG and S25FL008K0XMFI010, the SST25WF080BT-40E/SN uniquely combines AEC-Q100 qualification, 1.8V operation, Dual I/O capability, and 2 mm × 3 mm USON packaging - making it the only option meeting all requirements for space-constrained, automotive-grade firmware storage.

FAQ
What is the maximum clock frequency supported by SST25WF080BT-40E/SN in High-Speed Read mode?
The SST25WF080BT-40E/SN supports up to 40 MHz in High-Speed Read mode (0BH instruction), which includes one dummy byte after the address. This is confirmed in the DS20005164E datasheet Section 5.2 and Table 5-1. The 40 MHz operation is valid across the full –40°C to +125°C temperature range and 1.65–1.95V supply, making SST25WF080BT-40E/SN suitable for high-performance automotive boot applications.
Does SST25WF080BT-40E/SN support both SPI Mode 0 and Mode 3?
Yes, SST25WF080BT-40E/SN explicitly supports both SPI Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1), as stated in the Features section and Section 4.0 of DS20005164E. In both modes, SI is sampled on the rising edge of SCK and SO is driven on the falling edge. The difference lies only in the idle state of SCK (low in Mode 0, high in Mode 3), allowing compatibility with diverse host controllers.
What package type is used for SST25WF080BT-40E/SN?
SST25WF080BT-40E/SN uses an 8-contact USON package measuring 2 mm × 3 mm with 0.5 mm pitch, as specified in the "Packages Available" feature list and Figure 2-1 of DS20005164E. This ultra-compact, near-chip-scale package provides significant PCB area savings versus the alternative 8-lead SOIC (150 mils) variant, while maintaining RoHS compliance and MSL3 handling requirements.
How does the HOLD# pin function during active SPI communication?
The HOLD# pin on SST25WF080BT-40E/SN suspends an ongoing SPI transaction without deselecting the device or resetting internal state. As defined in Section 4.0.1 and Figure 4-2 of DS20005164E, HOLD# must be asserted while SCK is low; SO enters high-impedance, while SI and SCK remain functional. Communication resumes upon de-assertion of HOLD# (rising edge) synchronized with SCK low - enabling deterministic pause/resume in real-time systems.
Is SST25WF080BT-40E/SN qualified for automotive applications?
Yes, SST25WF080BT-40E/SN is AEC-Q100 qualified, as explicitly stated in the Features section of DS20005164E. It is rated for the Extended temperature range of –40°C to +125°C and has undergone stress testing per AEC-Q100 Rev G requirements. This qualification covers the specific USON-packaged variant SST25WF080BT-40E/SN, confirming suitability for under-hood and dashboard-mounted automotive electronics.
