Product details
Overview
SST25VF080B-80-4C-QAE-T from Microchip Technology is an 8 Mbit SPI serial flash memory IC with 80 MHz high-speed read capability, single 2.7–3.6 V supply operation, and SuperFlash® technology enabling 100,000 program/erase cycles. It supports uniform 4 KByte sectors and 32/64 KByte overlay blocks, and is used for firmware storage in embedded microcontroller boot loaders.
For engineers reviewing the SST25VF080B-80-4C-QAE-T datasheet, SST25VF080B-80-4C-QAE-T pinout, SST25VF080B-80-4C-QAE-T application, or SST25VF080B-80-4C-QAE-T equivalent, key selection considerations include its 80 MHz high-speed read timing, hardware/software end-of-write detection, AAI programming mode, and industrial temperature range (–40°C to +85°C) in a 8-contact WSON package.
Technical Context
The SST25VF080B-80-4C-QAE-T implements a four-wire SPI interface compliant with Mode 0 and Mode 3 protocols, using SCK, SI, SO, CE#, WP#, and HOLD# signals for command, address, and data transfer. Its internal SuperFlash® split-gate cell architecture enables faster erase times and lower energy per operation versus conventional flash.
It features dual end-of-write detection: software polling of the BUSY bit in the status register (bit 0), or hardware RY/BY# output on SO during Auto Address Increment (AAI) programming when enabled via EBSY (70H) command. Block protection is managed through BP3–BP0 bits and lock-down control via BPL bit and WP# pin.

| Uniform Erase Architecture | Independent 4 KByte sector, 32 KByte block, and 64 KByte block erase - enables granular firmware update without full chip erase |
| SuperFlash® Technology | Split-gate cell with thick-oxide tunneling injector delivers 35 ms chip-erase (typical) and 7 µs byte-program - improves system boot speed |
Applications
| Boot Code Storage | Firmware Update Storage |
|---|---|
|
Use Scenario: Storing primary bootloader and initial firmware image for ARM Cortex-M or RISC-V microcontrollers. IC Role / Device Role / Timing Role: Non-volatile code storage accessed during cold start; provides deterministic 80 MHz read latency for fast boot. Use Value: Enables sub-100 ms boot time due to high-speed read and wrap-around addressing, reducing system initialization delay. |
Use Scenario: Holding field-upgradable application firmware images in IoT edge nodes with OTA capability. IC Role / Device Role / Timing Role: Dual-bank storage partitioned via BP bits; one bank active while other receives update via AAI programming. Use Value: Supports atomic firmware swaps with zero downtime - sector/block erase preserves valid code during partial writes. |
| Configuration Parameter Storage | Secure Key Storage |
|
Use Scenario: Retaining calibration data, network credentials, and device-specific settings across power cycles in industrial sensors. IC Role / Device Role / Timing Role: Low-power non-volatile storage accessed infrequently; leverages 5 µA standby current for energy-sensitive deployments. Use Value: Eliminates need for external EEPROM or battery-backed SRAM - reduces BOM count and board area. |
Use Scenario: Storing cryptographic keys and secure boot certificates in medical or automotive control units requiring tamper resistance. IC Role / Device Role / Timing Role: Hardware write-protection (WP# + BPL) and software BP bits prevent unauthorized overwrite of protected regions. Use Value: Provides physical-layer protection against malicious firmware injection - keys remain immutable once locked down. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar SPI serial flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Winbond W25Q80DVSSIG | 8 Mbit, 104 MHz max read, quad-SPI capable, but lacks AAI programming and hardware RY/BY# on SO | Supports faster read but requires additional GPIO or polling for write completion; no native hold/resume during programming | Choose for higher bandwidth read-only use cases where AAI and hardware busy signaling are unnecessary |
| Micron MT25QL80ABB8E12-0SIT | 8 Mbit, 133 MHz read, supports DTR mode and SFDP, but requires 1.8 V or 3 V supply (not 2.7–3.6 V range) | Needs voltage translation in 3.3 V systems; offers JEDEC-standard configuration but higher complexity in legacy designs | Prefer when migrating to JEDEC-compliant platforms with SFDP-based auto-configuration and future-proofing requirements |
Compared with SST25VF080B-80-4C-QAE-T, W25Q80DVSSIG trades AAI and hardware RY/BY# for higher read speed and quad-I/O, while MT25QL80ABB8E12-0SIT adds SFDP and DTR at the cost of supply voltage compatibility and design simplicity.

FAQ
What is the operating temperature range for SST25VF080B-80-4C-QAE-T?
The SST25VF080B-80-4C-QAE-T is rated for industrial temperature operation from –40°C to +85°C. This range is confirmed in the DS25045A datasheet under "Temperature Range" and applies specifically to the -4C suffix variant. The device maintains full specification compliance-including 80 MHz read timing and 100,000-cycle endurance-across this entire range, making it suitable for deployment in harsh environments such as factory automation and outdoor telemetry equipment.
Does SST25VF080B-80-4C-QAE-T support quad-SPI or QPI interface modes?
No, SST25VF080B-80-4C-QAE-T does not support quad-SPI or QPI. It implements a standard four-wire SPI interface (SCK, SI, SO, CE#) compatible only with Mode 0 and Mode 3. Unlike later-generation serial flash devices, it lacks dedicated IO2/IO3 pins and corresponding instruction sets for quad I/O operation. All data transfers-including high-speed read (0BH), AAI programming (ADH), and status reads-are strictly single-bit in/out on SI and SO lines.
How is hardware end-of-write detection enabled on SST25VF080B-80-4C-QAE-T?
Hardware end-of-write detection on SST25VF080B-80-4C-QAE-T is enabled by issuing the EBSY command (70H) before initiating AAI programming. This reconfigures the SO pin to output real-time RY/BY# status ('0' = busy, '1' = ready) during AAI operations. CE# must remain low during status sampling. To disable, issue DBSY (80H) after completing AAI and before exiting the mode. This feature eliminates software polling overhead and is exclusive to AAI mode-not available during byte-program or erase operations.
What package type is used for SST25VF080B-80-4C-QAE-T?
SST25VF080B-80-4C-QAE-T uses an 8-contact WSON package measuring 6 mm × 5 mm with 0.5 mm pitch. The "QAE" suffix explicitly denotes this WSON variant, as confirmed in Microchip's ordering information tables and package drawings (DS25045A, Figure 2). It is distinct from SOIC (200/150 mil) and PDIP variants, and features exposed thermal pad for improved thermal dissipation in high-density layouts.
Can SST25VF080B-80-4C-QAE-T be used as a direct replacement for SST25VF080B-50-4C-QAE-T?
Yes, SST25VF080B-80-4C-QAE-T is functionally and pin-compatible with SST25VF080B-50-4C-QAE-T, differing only in maximum clock frequency (80 MHz vs. 50 MHz high-speed read) and associated AC timing parameters. All DC characteristics, pinout, instruction set, memory organization, and software features-including AAI, HOLD#, WP#, and status register behavior-are identical. No PCB or firmware changes are required to upgrade, though timing margins in high-frequency read paths should be verified.
