Product details
Overview
SST25VF080B-80-4I-SAE from Microchip Technology is an 8 Mbit SPI serial flash memory IC designed for embedded firmware storage and code execution in resource-constrained systems. It operates at 2.7–3.6 V, supports 80 MHz high-speed read via SPI Mode 0/3, features uniform 4 KByte sectors and 64 KByte blocks, and delivers 100,000 program/erase cycles with >100-year data retention - deployed in industrial microcontroller boot loaders and IoT sensor node configuration storage.
For engineers reviewing the SST25VF080B-80-4I-SAE datasheet, SST25VF080B-80-4I-SAE pinout, SST25VF080B-80-4I-SAE application, or SST25VF080B-80-4I-SAE equivalent, key selection criteria include verified 80 MHz high-speed read timing, industrial temperature range (–40°C to +85°C), SOIC-8 (200 mil) package compatibility, and SuperFlash-based endurance under single-supply operation.
Technical Context
The SST25VF080B-80-4I-SAE implements a four-wire SPI interface with hardware-level HOLD# and WP# control lines, enabling non-disruptive suspend and selective block protection. Its SuperFlash technology uses split-gate cells and thick-oxide tunneling injectors to achieve faster erase times (18 ms sector-erase, 35 ms chip-erase) and lower active current (10 mA typical) versus conventional NOR flash.
It supports Auto Address Increment (AAI) word-programming to reduce sequential write overhead, and dual end-of-write detection - software polling of BUSY bit or hardware RY/BY# status output on SO pin during AAI mode - ensuring deterministic timing for real-time firmware updates.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 8 Mbit (1 MByte) organized as uniform 4 KByte sectors, 32 KByte and 64 KByte overlay blocks - enables fine-grained firmware partitioning and OTA update staging. |
| Max Clock Frequency | 80 MHz for High-Speed Read (0BH command with dummy byte) - sustains ≥80 MB/s effective throughput for XIP-capable MCUs. |
| Supply Voltage | 2.7–3.6 V single supply - compatible with 3.3 V logic domains without level-shifting; eliminates need for auxiliary voltage rails. |
| Endurance & Retention | 100,000 program/erase cycles typical; >100 years data retention at +85°C - validated for long-life industrial deployments with infrequent field updates. |
| Active/Standby Current | 10 mA typical active read current; 5 µA typical standby current - reduces average power in battery-backed or energy-harvested edge nodes. |
| Operating Temperature | –40°C to +85°C (Industrial grade) - qualified for use in automotive body control modules and factory automation controllers. |
| Erase/Program Speed | 18 ms typical sector/block-erase; 7 µs typical byte-program; 35 ms typical chip-erase - minimizes firmware update window and improves production programming throughput. |
Pinout & Package
Package: 8-lead SOIC (200 mil), RoHS-compliant, surface-mountable with standard reflow profile.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CE# | Chip Enable | Active-low device select; must remain low throughout command sequence - enables multi-device SPI daisy-chaining with independent addressing. |
| SO | Serial Data Output | Tri-state output for read data and AAI-mode RY/BY# status - allows hardware busy signaling without CPU polling overhead. |
| WP# | Write Protect | Hardware lock-down control for Block-Protection-Lock (BPL) bit - prevents accidental status register modification during field operation. |
| VSS | Ground | Reference return path for all I/O and core logic - requires low-impedance PCB connection to minimize noise coupling into SPI signals. |
| VDD | Power Supply | 2.7–3.6 V core and I/O supply - mandates local 100 nF ceramic decoupling within 5 mm of pin for stable high-frequency read operation. |
| HOLD# | Hold Control | Active-low suspend signal; pauses ongoing SPI transaction without resetting internal state - preserves address pointer during interrupt-driven MCU contexts. |
| SCK | Serial Clock | Input clock synchronized to SPI Mode 0 (CPOL=0, CPHA=0) or Mode 3 (CPOL=1, CPHA=1) - determines sampling edge for SI and SO timing alignment. |
| SI | Serial Data Input | Command, address, and data input line latched on rising SCK edge - supports standard SPI master peripherals without custom protocol translation. |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash Technology | Split-gate cell architecture with thick-oxide tunneling injector - achieves 3× faster erase and 50% lower program current vs. standard NOR flash, reducing total energy per operation. |
| 80 MHz High-Speed Read | 0BH command with 1-byte dummy cycle - delivers sustained 80 MB/s read bandwidth for XIP execution in Cortex-M4/M7 applications. |
| Auto Address Increment (AAI) | ADH command with 2-byte data per cycle - cuts sequential programming time by 60% vs. byte-program mode when writing full firmware images. |
| Flexible Block Protection | BP3–BP0 bits + BPL lock-down - enables hardware-enforced write protection of bootloader, calibration tables, or security keys without software intervention. |
| Hardware End-of-Write Detection | EBSY (70H) command reconfigures SO pin as RY/BY# - eliminates polling loops and guarantees deterministic AAI completion timing for hard real-time systems. |

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 support, 2.7–3.6 V, SOIC-8 - adds QPI mode and faster clock but lacks AAI programming. | Preferred where higher throughput or quad I/O is required; not drop-in for legacy AAI-dependent firmware. | Select if migrating to QSPI-enabled MCU platforms; verify absence of AAI usage in existing codebase. |
| Macronix MX25L8006EM1I-12G | 8 Mbit, 80 MHz max read, standard SPI only, 2.7–3.6 V, SOIC-8 - matches clock spec but uses conventional NOR cell; 10,000-cycle endurance. | Suitable for cost-sensitive consumer applications with shorter lifecycle; insufficient for industrial firmware update frequency. | Choose only for non-critical, short-deployment products; avoid where >50,000 field updates are expected. |
Compared with W25Q80DVSSIG and MX25L8006EM1I-12G, the SST25VF080B-80-4I-SAE uniquely balances 80 MHz performance with SuperFlash endurance and AAI acceleration - making it optimal for industrial firmware storage where update reliability outweighs raw bandwidth.

FAQ
What is the maximum clock frequency supported by SST25VF080B-80-4I-SAE for high-speed read operations?
The SST25VF080B-80-4I-SAE supports up to 80 MHz for High-Speed Read operations using the 0BH command with a dummy byte. This specification applies exclusively to variants designated with "-80" in the part number, such as SST25VF080B-80-4I-SAE, and is validated across the full industrial temperature range (–40°C to +85°C).
Does SST25VF080B-80-4I-SAE support both SPI Mode 0 and Mode 3?
Yes, SST25VF080B-80-4I-SAE is fully compatible with SPI Mode 0 (CPOL = 0, CPHA = 0) and Mode 3 (CPOL = 1, CPHA = 1). The device samples SI on the rising edge and drives SO on the falling edge of SCK in both modes, allowing seamless integration with diverse MCU SPI peripherals without protocol translation.
How does the HOLD# pin function during active SPI communication in SST25VF080B-80-4I-SAE?
In SST25VF080B-80-4I-SAE, the HOLD# pin suspends ongoing SPI transactions without deselecting the device or resetting internal state. When asserted low while CE# is active, it places SO in high-impedance and freezes the address pointer - enabling MCU interrupt handling without losing context or requiring re-initialization of the command sequence.
What write protection mechanisms are implemented in SST25VF080B-80-4I-SAE?
SST25VF080B-80-4I-SAE provides dual-layer write protection: hardware-based via the WP# pin (enabling BPL lock-down of status register bits) and software-based via BP3–BP0 bits in the status register. Together, they allow selective, persistent protection of memory regions - including bootloader sections - against accidental or malicious overwrite.
Is SST25VF080B-80-4I-SAE compatible with the same PCB footprint as SST25VF080B-50-4I-SAE?
Yes, SST25VF080B-80-4I-SAE shares identical mechanical dimensions and pinout with SST25VF080B-50-4I-SAE - both use the 8-lead SOIC (200 mil) package. The "-80" suffix denotes higher-speed characterization, not physical differentiation; no PCB layout change is required for migration between these speed grades.
