Product details
Overview
SST25VF080B-80-4I-S2AE-T from Microchip Technology is an 8 Mbit SPI serial flash memory IC with single-supply 2.7–3.6 V operation, 80 MHz high-speed read capability, uniform 4 KByte sector/32 KByte & 64 KByte block erase architecture, and industrial temperature range (–40°C to +85°C). It serves as nonvolatile program/data storage in microcontroller boot loaders, firmware update buffers, and embedded configuration memory.
For engineers reviewing the SST25VF080B-80-4I-S2AE-T datasheet, SST25VF080B-80-4I-S2AE-T pinout, SST25VF080B-80-4I-S2AE-T application, or SST25VF080B-80-4I-S2AE-T equivalent, key selection considerations include SPI Mode 0/3 compatibility, Auto Address Increment (AAI) programming support, hardware RY/BY# status via SO pin during AAI, 100,000-cycle endurance, and software/hardware write protection granularity.
Technical Context
The SST25VF080B-80-4I-S2AE-T implements a four-wire SPI interface (SCK, SI, SO, CE#) with dual-mode clock polarity support (Mode 0 and Mode 3), enabling interoperability with diverse host controllers. Its SuperFlash technology uses split-gate cells and thick-oxide tunneling for enhanced reliability over conventional NOR flash.
It supports three erase granularities-4 KByte sectors, 32 KByte blocks, and 64 KByte blocks-and features both byte-program and AAI-word-program modes. End-of-write detection is available via software polling of the BUSY bit or hardware-driven RY/BY# status on the SO pin when enabled by EBSY (70H) command.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPI serial flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Winbond W25Q80DVSSIG | 8 Mbit, 104 MHz max read, Quad SPI capable, no HOLD# pin, different status register layout | Lacks HOLD# and hardware RY/BY# on SO; supports QPI for higher throughput but requires host driver changes | Select if higher read bandwidth is prioritized and HOLD# functionality is not required in the system design |
| Micron MT25QL80ABB8E12-0SIT | 8 Mbit, 133 MHz max read, Octal DTR capable, different command set, requires VIO supply | Requires separate I/O voltage rail (1.7–2.0 V); incompatible status register and protection scheme; no AAI mode | Choose only when migrating to high-speed octal interface and full platform redesign is acceptable |
Compared with SST25VF080B-80-4I-S2AE-T, W25Q80DVSSIG offers faster read speed but removes HOLD# and hardware busy signaling, while MT25QL80ABB8E12-0SIT demands new power and software architecture - neither provides drop-in replacement capability without hardware or firmware revision.

FAQ
What is the maximum operating frequency of the SST25VF080B-80-4I-S2AE-T?
The SST25VF080B-80-4I-S2AE-T supports up to 80 MHz for High-Speed Read operations using the 0BH command. This rating applies specifically to the -80 suffix variant and is validated across the full industrial temperature range (–40°C to +85°C) and 2.7–3.6 V supply. Standard Read (03H) operates up to 33 MHz. The 80 MHz capability enables sub-13 ns per-byte read access, critical for fast boot and real-time firmware fetch scenarios.
Does the SST25VF080B-80-4I-S2AE-T support SPI Mode 3?
Yes, the SST25VF080B-80-4I-S2AE-T fully supports both SPI Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1). In Mode 3, the SCK signal idles high, and data is sampled on the rising edge of SCK for SI and shifted out on the falling edge for SO. This dual-mode compatibility ensures seamless integration with a wide range of microcontrollers and FPGAs without requiring hardware modifications to the SPI peripheral configuration.
How does hardware end-of-write detection work on the SST25VF080B-80-4I-S2AE-T?
Hardware end-of-write detection on the SST25VF080B-80-4I-S2AE-T is enabled by issuing the EBSY command (70H), which reconfigures the SO pin to output RY/BY# status during Auto Address Increment (AAI) programming. While active, SO drives '0' when busy and '1' when ready - eliminating software polling overhead. To exit this mode, the WRDI (04H) and DBSY (80H) commands must be issued in sequence. This feature is exclusive to AAI mode and not available during byte-program or erase operations.
What package type is used for the SST25VF080B-80-4I-S2AE-T?
The SST25VF080B-80-4I-S2AE-T uses an 8-lead SOIC package with 200 mil body width (standard JEDEC MS-012AC). It is RoHS-compliant, surface-mountable, and compatible with standard reflow soldering profiles. Pinout matches industry-standard SPI flash layouts, simplifying PCB layout reuse across designs. The S2AE-T suffix explicitly denotes this SOIC-200 package variant with industrial temperature grading.
Can the SST25VF080B-80-4I-S2AE-T be used in automotive applications?
The SST25VF080B-80-4I-S2AE-T is qualified for industrial temperature range (–40°C to +85°C) and meets AEC-Q100 stress testing requirements per Microchip's documentation for this family. While not officially AEC-Q100 certified as a standalone part, its electrical and thermal specifications align with many automotive body electronics applications - including gateway modules, lighting controllers, and HVAC interfaces - provided system-level qualification is completed per OEM requirements.
