Product details
Overview
SST25VF080B-80-4C-S2AE-T 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 0BH command with dummy byte, delivers 10 mA typical active read current, and features uniform 4 KByte sectors with 100,000-cycle endurance - deployed in industrial control panels requiring reliable boot code retention.
For engineers reviewing the SST25VF080B-80-4C-S2AE-T datasheet, SST25VF080B-80-4C-S2AE-T pinout, SST25VF080B-80-4C-S2AE-T application, or SST25VF080B-80-4C-S2AE-T equivalent, key selection criteria include SPI Mode 0/3 compatibility, hardware RY/BY# status output during AAI programming, 8-lead SOIC (200 mil) package mapping, and software block-protection granularity down to 4 KByte sectors.
Technical Context
The SST25VF080B-80-4C-S2AE-T implements a four-wire SPI interface with CE#, SCK, SI, and SO lines, supporting both Mode 0 (SCK idle low) and Mode 3 (SCK idle high). Its SuperFlash technology uses split-gate cells and thick-oxide tunneling for enhanced reliability over conventional NOR flash.
It integrates a software-configurable status register with BUSY/WEL/BP3–BP0/AAI/BPL bits, enabling precise memory protection and Auto Address Increment (AAI) word-programming. Hardware end-of-write detection reconfigures SO as RY/BY# during AAI mode when enabled via EBSY (70H) command.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 8 Mbit (1 MByte), organized as 2048 × 4 KByte sectors - enables full firmware image storage for mid-tier microcontrollers. |
| Max Clock Frequency | 80 MHz for High-Speed Read (0BH + dummy byte) - reduces boot time by ~2.4× vs. standard 33 MHz Read (03H). |
| Supply Voltage | 2.7–3.6 V single supply - compatible with 3.3 V logic rails without level-shifting. |
| Erase Granularity | Uniform 4 KByte sectors, 32 KByte blocks, 64 KByte blocks - allows fine-grained firmware updates without full chip erase. |
| Endurance & Retention | 100,000 program/erase cycles; >100 years data retention - suitable for field-upgradable industrial devices with 10+ year service life. |
| Active Read Current | 10 mA typical at 80 MHz - enables low-power operation in battery-backed or energy-harvested edge nodes. |
| Standby Current | 5 µA typical - minimizes quiescent power in always-on monitoring systems. |
Pinout & Package
Package: 8-lead SOIC (200 mil), surface-mount, RoHS-compliant.
| 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 shared SCK/SI/SO. |
| SO | Serial Data Output | Drives read data on falling SCK edge; reconfigurable as RY/BY# during AAI mode - eliminates polling overhead in real-time firmware update paths. |
| WP# | Write Protect | Enables lock-down of Block-Protection bits (BP3–BP0) via BPL bit - prevents accidental firmware corruption during power transients. |
| HOLD# | Hold Control | Suspends ongoing SPI transfer without deselecting device - preserves clock phase alignment during interrupt-driven host CPU servicing. |
| SCK | Serial Clock | Timing reference for all SPI transfers; sampled on rising edge for input, drives output on falling edge - ensures deterministic timing across Mode 0/3. |
| SI | Serial Data Input | Accepts opcodes, addresses, and data MSB-first - supports standard SPI controller peripherals without custom firmware. |
| VDD | Power Supply | 2.7–3.6 V supply input - decoupling capacitor placement near this pin critical for stable high-frequency read performance. |
| VSS | Ground | Reference return path for all I/O and core logic - requires low-impedance connection to minimize noise coupling into SO signal. |
Key Features
| Feature | Design Value |
|---|---|
| Auto Address Increment (AAI) Programming | Reduces sequential byte-program time by eliminating per-byte address retransmission - cuts full-array programming latency by up to 40% vs. standard Byte-Program. |
| Hardware RY/BY# Status on SO | SO pin outputs real-time busy status during AAI mode after EBSY (70H) command - removes software polling loop, freeing CPU cycles for concurrent tasks. |
| Flexible Block Protection | Software-controlled BP3–BP0 bits protect memory regions from 1/16 (64 KByte) to full array (8 MBit) - enables secure bootloader + application partitioning. |
| SuperFlash Technology | Split-gate cell architecture with thick-oxide injector achieves <100 ms typical sector erase (vs. >500 ms in legacy NOR) - accelerates field firmware recovery. |
| SPI Mode 0 and Mode 3 Support | Interoperable with diverse host controllers (e.g., ARM Cortex-M, PIC, FPGA soft-SPI) without hardware modification - simplifies platform reuse. |
Applications

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 support, no HOLD#/WP# pins in SOIC-8 variant | Lacks hardware RY/BY# on SO; requires software polling or external GPIO monitoring | Select if higher throughput via Quad I/O is needed and AAI/hardware status not required. |
| Macronix MX25L8006EM1I-12G | 8 Mbit, 80 MHz max read, same pinout, but only supports SPI Mode 0 (not Mode 3) | Incompatible with hosts requiring Mode 3 timing; no AAI programming mode | Choose only for legacy designs already using Mode 0-only controllers and no AAI dependency. |
Compared with W25Q80DVSSIG and MX25L8006EM1I-12G, the SST25VF080B-80-4C-S2AE-T uniquely combines 80 MHz read, AAI programming, hardware RY/BY# on SO, and dual-mode SPI compatibility - making it optimal for real-time, interrupt-sensitive firmware update architectures.

The SST25VF080B-80-4C-S2AE-T supports up to 80 MHz for High-Speed Read operations using the 0BH command with a dummy byte. Standard Read (03H) operates up to 33 MHz. This 80 MHz capability is confirmed in Table 14 of the DS25045A datasheet and applies specifically to the "-80-" suffix variant like SST25VF080B-80-4C-S2AE-T.
Does SST25VF080B-80-4C-S2AE-T support both SPI Mode 0 and Mode 3?
Yes, SST25VF080B-80-4C-S2AE-T explicitly supports both SPI Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1), as stated in the "Device Operation" section (page 5) of the DS25045A datasheet. This dual-mode compatibility ensures interoperability with a broad range of host microcontrollers and FPGAs.

Hardware end-of-write detection on SST25VF080B-80-4C-S2AE-T reconfigures the SO pin as RY/BY# during Auto Address Increment (AAI) programming. After issuing the EBSY (70H) command, SO outputs '0' when busy and '1' when ready - eliminating software polling. This feature is documented in the "Hardware End-of-Write Detection" section (page 13) of DS25045A.
What package type is used for SST25VF080B-80-4C-S2AE-T?
