Product details
Overview
SST25VF080B-80-4I-S2AE 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 industrial temperature range (–40°C to +85°C). It uses SuperFlash technology for enhanced reliability (100,000 program/erase cycles, >100 years data retention) and supports uniform 4 KByte sectors, 32 KByte and 64 KByte overlay blocks - deployed in firmware storage, boot code execution, and configuration data retention for embedded microcontrollers.
For engineers reviewing the SST25VF080B-80-4I-S2AE datasheet, SST25VF080B-80-4I-S2AE pinout, SST25VF080B-80-4I-S2AE application, or SST25VF080B-80-4I-S2AE equivalent, key selection considerations include its 80 MHz high-speed read mode (0BH command with dummy byte), Auto Address Increment (AAI) programming for accelerated multi-byte writes, hardware RY/BY# status output via SO during AAI, and flexible software/hardware write protection using WP# and HOLD# pins.
Technical Context
The SST25VF080B-80-4I-S2AE implements a four-wire SPI interface compliant with Mode 0 and Mode 3 protocols, supporting both standard Read (03H) and High-Speed Read (0BH) instructions. Its internal SuperFlash architecture features split-gate cells and thick-oxide tunneling injectors, enabling lower program/erase current and shorter timing versus conventional NOR flash.
It integrates a software-configurable status register with BUSY/WEL/BP/BPL/AAI bits and supports three end-of-write detection methods: software polling of BUSY, hardware RY/BY# output on SO (enabled via EBSY command), and fixed timing wait (TBP/TSE/TBE). The device requires WREN before any write operation and enforces block protection based on BP3–BP0 bits with lock-down control via BPL and WP#.
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 |
| Max Clock Frequency | 80 MHz for High-Speed Read (0BH), enabling ~10 MB/s sustained throughput |
| Supply Voltage | 2.7–3.6 V - single supply enables direct interfacing with 3.3 V logic without level shifters |
| Endurance & Retention | 100,000 program/erase cycles typical; >100 years data retention at 85°C |
| Active Read Current | 10 mA typical at 80 MHz - low power consumption supports battery-backed or energy-constrained systems |
| Standby Current | 5 µA typical - enables ultra-low-power sleep modes in always-on embedded devices |
| Erase Times | Chip-Erase: 35 ms typical; Sector/Block-Erase: 18 ms typical - faster than legacy SPI flash alternatives |

Pinout & Package
Package: 8-lead SOIC (200 mils), 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; high-to-low transition initiates instruction acceptance |
| SO | Serial Data Output | Outputs read data on falling SCK edge; reconfigurable as RY/BY# status pin during AAI when EBSY enabled |
| WP# | Write Protect | Enables/disables BPL bit lock-down; when low, prevents modification of BP3–BP0 unless BPL = 0 |
| VSS | Ground | Reference return path for all digital and analog circuitry; requires low-impedance PCB connection |
| VDD | Power Supply | 2.7–3.6 V supply input; decoupling capacitor (0.1 µF) required near pin for noise immunity |
| HOLD# | Hold Control | Suspends ongoing SPI transaction without deselecting device; allows host to service higher-priority interrupts |
| SCK | Serial Clock | Timing reference for SI/SO; rising edge latches input, falling edge drives output; supports Mode 0 (idle low) and Mode 3 (idle high) |
| SI | Serial Data Input | Accepts opcodes, addresses, and data MSB-first on rising SCK edge; high-impedance when CE# high |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash Technology | Split-gate cell + thick-oxide injector delivers 10× faster erase and lower program current vs. standard NOR flash |
| 80 MHz High-Speed Read | 0BH command with dummy byte achieves 10 MB/s throughput - critical for fast boot and real-time firmware loading |
| Auto Address Increment (AAI) | Two-byte per command programming eliminates address retransmission overhead, cutting full-array write time by ~40% |
| Hardware RY/BY# on SO | EBSY (70H) reconfigures SO as active-low busy indicator during AAI - removes software polling latency |
| Flexible Block Protection | BP3–BP0 bits enable selective protection of upper 1/16 to full array; BPL+WP# lock-down prevents accidental configuration change |
| HOLD# Pin Functionality | Pauses SPI communication mid-sequence without resetting internal state - preserves address pointer and command context |

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 clock, Quad SPI support, 3.3 V only, no HOLD# pin | Lacks HOLD# and hardware RY/BY#; requires software polling or external GPIO for busy detection | Choose for higher throughput where Quad SPI and faster clock offset absence of HOLD# |
| Cypress S25FL008A0XMFI00 | 8 Mbit, 66 MHz max clock, dual/quad SPI, 2.7–3.6 V, includes reset pin | Slower max read speed; supports dual/quad modes but lacks AAI programming acceleration | Prefer when system requires reset functionality or dual-IO compatibility, not AAI optimization |
Compared with SST25VF080B-80-4I-S2AE, W25Q80DVSSIG offers higher bandwidth but sacrifices HOLD# and hardware busy signaling, while S25FL008A0XMFI00 provides broader SPI mode flexibility at the cost of reduced AAI efficiency and lower 66 MHz read ceiling.

FAQ
What is the maximum operating frequency of SST25VF080B-80-4I-S2AE?
The SST25VF080B-80-4I-S2AE supports up to 80 MHz for High-Speed Read operations using the 0BH command with a dummy byte. This is confirmed in Table 14 of DS25045A and distinguishes it from the -50 variant (66 MHz). Standard Read (03H) operates up to 33 MHz. The 80 MHz rating applies only to High-Speed Read mode and requires proper signal integrity layout.
Does SST25VF080B-80-4I-S2AE support Auto Address Increment (AAI) programming?
Yes, SST25VF080B-80-4I-S2AE fully supports AAI programming using the ADH (1010 1101b) command. It enables sequential two-byte writes without retransmitting the address, reducing total programming time. AAI mode is indicated by the AAI bit (bit 6) in the status register and requires prior WREN execution. Hardware RY/BY# status on SO is available during AAI when enabled via EBSY (70H).
What package type is used in SST25VF080B-80-4I-S2AE?
SST25VF080B-80-4I-S2AE uses an 8-lead SOIC package with 200 mil body width (standard JEDEC MS-012), as specified in Figure 2 and Table 1 of DS25045A. The "S2AE" suffix explicitly denotes this SOIC-200 package variant. It is RoHS-compliant and compatible with standard surface-mount reflow profiles.
How does write protection work on SST25VF080B-80-4I-S2AE?
SST25VF080B-80-4I-S2AE implements dual-layer write protection: software-based via BP3–BP0 bits in the status register (configurable protection levels from upper 1/16 to full array), and hardware-enforced via the WP# pin controlling BPL bit lock-down. When WP# is low, BPL=1 prevents further changes to BP bits. Block protection is active only when WEL=1 and the target address falls within protected regions.
Is SST25VF080B-80-4I-S2AE suitable for industrial temperature applications?
Yes, SST25VF080B-80-4I-S2AE is rated for the industrial temperature range of –40°C to +85°C, as stated in the "Temperature Range" section of DS25045A. The "I" in the part number explicitly denotes industrial grade. It maintains full specification compliance-including 80 MHz read performance, 100,000 cycle endurance, and 5 µA standby current-across this full range.
