Product details
Overview
SST25PF080B-80-4C-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 from a single 2.3–3.6V supply, supports SPI Modes 0 and 3, delivers up to 80 MHz read speed (at 2.7–3.6V), features uniform 4 KByte sectors and 64 KByte overlay blocks, and is rated for commercial temperature range (0°C to +70°C).
For engineers reviewing the SST25PF080B-80-4C-SAE datasheet, SST25PF080B-80-4C-SAE pinout, SST25PF080B-80-4C-SAE application, or SST25PF080B-80-4C-SAE equivalent, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, confirmed alternatives, and supply-ready availability details - all grounded in Microchip's DS20005137B documentation.
Technical Context
The SST25PF080B-80-4C-SAE implements a four-wire SPI interface with dual-mode compatibility (Mode 0 and Mode 3), enabling seamless integration with standard microcontroller SPI peripherals. Its SuperFlash technology uses split-gate cells and thick-oxide tunneling injectors to achieve superior endurance (100,000 program/erase cycles) and data retention (>100 years).
It supports hardware- and software-based end-of-write detection: BUSY bit polling via Status Register (RDSR), or RY/BY# status output on SO during AAI programming (enabled by EBSY command). The device includes dedicated HOLD# and WP# pins for real-time serial transaction suspension and block-level write protection control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 8 Mbit (1 MByte) - sufficient for boot code, configuration tables, and firmware images in MCU-based edge devices. |
| Supply Voltage | 2.3–3.6V - compatible with modern 3.3V I/O domains and eliminates need for level shifters in most host designs. |
| Max Read Frequency | 80 MHz (2.7–3.6V) - enables fast XIP (execute-in-place) performance with sub-100 ns effective access time per byte. |
| Erase Granularity | Uniform 4 KByte sectors / 32 KByte & 64 KByte overlay blocks - allows precise firmware partitioning and OTA update management. |
| Write Endurance | 100,000 cycles (typical) - supports frequent field updates in industrial logging or calibration storage applications. |
| Data Retention | >100 years - ensures long-term reliability for sealed or maintenance-free deployments without refresh cycles. |
| Active Read Current | 10 mA (typical) - enables low-power operation in battery-backed or energy-harvesting systems during active reads. |
| Standby Current | 5 μA (typical) - minimizes quiescent power draw during system sleep modes without requiring full power-down sequencing. |
Pinout & Package
Package: 8-lead SOIC (200 mils), RoHS-compliant, surface-mountable with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CE# | Chip Enable | Active-low chip select; must remain low throughout command sequences; high-to-low transition initiates instruction acceptance. |
| SO | Serial Data Output | Provides read data or RY/BY# busy status during AAI mode; tri-stated when CE# is high or HOLD# is active. |
| WP# | Write Protect | Enables BPL bit lock-down; when low, prevents modification of BP2–BP0 and BPL bits unless BPL = 0. |
| VSS | Ground | Reference return path for all digital and analog circuitry; requires low-impedance connection to PCB ground plane. |
| VDD | Power Supply | 2.3–3.6V main supply; decoupling capacitor (0.1 μF ceramic) required within 5 mm of pin for stable high-speed operation. |
| HOLD# | Hold Control | Suspends ongoing SPI transfer without deselecting device; holds SCK low state and places SO in high-Z; resumes on rising edge aligned with next SCK low. |
| SCK | Serial Clock | Timing reference for all SPI transfers; data sampled on rising edge (SI), output shifted on falling edge (SO); supports Mode 0 (SCK idle low) and Mode 3 (SCK idle high). |
| SI | Serial Data Input | Receives opcodes, addresses, and data; MSB-first; latched on rising edge of SCK; must be stable before clock edge. |
Key Features
| Feature | Design Value |
|---|---|
| Auto Address Increment (AAI) Programming | Reduces total programming time by eliminating address retransmission for sequential word writes - critical for rapid firmware patching. |
| Hardware RY/BY# Status on SO Pin | Eliminates software polling overhead during AAI programming by driving busy/ready status directly on SO - improves deterministic timing in real-time systems. |
| Flexible Block Protection Scheme | Seven configurable protection levels (via BP2–BP0) allow selective locking of upper memory regions - secures bootloader while permitting application updates. |
| 256-bit Security ID with Lockout | Factory-programmed 64-bit ID + user-programmable 192-bit space, permanently lockable via Lockout SID command - enables secure device authentication and anti-cloning. |
| Uniform Erase Architecture | Consistent 4 KByte sector, 32 KByte, and 64 KByte block erase times (18 ms typ.) simplify wear-leveling algorithm design and reduce worst-case latency variance. |

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 |
|---|---|---|---|
| SST25VF080B | Direct successor; identical pinout, same density and voltage range, improved reliability specs, and extended lifecycle support (SST25PF080B is obsolete per Microchip). | Drop-in replacement for new designs; supports same SPI modes, AAI, and security ID features with enhanced endurance and retention. | Select SST25VF080B for all new designs - it supersedes SST25PF080B with no layout or firmware changes required. |
| AT25DF081A-SSH-T | 8 Mbit SPI flash from Microchip (formerly Atmel); 2.7–3.6V operation; max 85 MHz read; supports SFDP; lacks Security ID and AAI programming. | Better high-speed read performance but no hardware RY/BY# or auto-increment programming; different status register map and protection scheme. | Choose AT25DF081A-SSH-T only if SFDP compatibility or marginally higher clock rate is prioritized over security and programming efficiency. |
Compared with SST25VF080B, the SST25PF080B-80-4C-SAE offers identical functionality but lacks ongoing manufacturing support; compared with AT25DF081A-SSH-T, it provides stronger security (lockable Security ID) and faster sequential programming (AAI), at the cost of slightly lower max clock rate and no SFDP.

FAQ
Is SST25PF080B-80-4C-SAE still in active production?
No - Microchip officially lists SST25PF080B-80-4C-SAE as obsolete in DS20005137B. It has been superseded by SST25VF080B, which maintains full pin, function, and software compatibility. Aetrix Electronics maintains limited legacy stock for existing production continuity, but new designs should use SST25VF080B.
What does the "-80-4C-SAE" suffix indicate for SST25PF080B-80-4C-SAE?
The "-80" denotes maximum 80 MHz read speed at 2.7–3.6V; "4C" specifies commercial temperature range (0°C to +70°C); "SAE" indicates 8-lead SOIC package with 200-mil body width and lead finish compliant with RoHS and JEDEC standards.
Can SST25PF080B-80-4C-SAE be used in place of SST25VF080B?
Yes - SST25PF080B-80-4C-SAE is functionally and pin-compatible with SST25VF080B, but SST25VF080B offers improved specifications (e.g., higher endurance, longer retention) and active manufacturing support. SST25PF080B-80-4C-SAE may be substituted in legacy systems, but SST25VF080B is mandatory for new designs.
Does SST25PF080B-80-4C-SAE support Quad SPI or Dual SPI modes?
No - SST25PF080B-80-4C-SAE supports only standard four-wire SPI (single I/O) in Modes 0 and 3. It does not implement Dual Output, Dual Input, or Quad I/O protocols. For Quad SPI capability, consider Microchip's SST26VF016B or equivalent.
How is hardware end-of-write detection enabled on SST25PF080B-80-4C-SAE?
Hardware end-of-write detection is enabled by issuing the EBSY command (70H) before initiating AAI programming. This configures the SO pin to output RY/BY# status ('0' = busy, '1' = ready) during AAI operations. The DBSY command (80H) disables this mode. Both commands require prior WREN execution.
