Product details
Overview
SST25PF080B-80-4C-QAE-T from Microchip Technology is an 8 Mbit SPI serial flash memory IC with single-supply operation (2.3–3.6 V), 80 MHz max clock frequency at 2.7–3.6 V, 100,000 program/erase endurance cycles, and >100 years data retention. It serves as nonvolatile code/data storage in microcontroller-based embedded systems requiring compact, low-pin-count memory interfacing via SPI.
For engineers reviewing the SST25PF080B-80-4C-QAE-T datasheet, SST25PF080B-80-4C-QAE-T pinout, SST25PF080B-80-4C-QAE-T application, or SST25PF080B-80-4C-QAE-T equivalent, key selection considerations include its SOIC-8 (200 mil) package, hardware hold/write-protect pins, Auto Address Increment (AAI) programming mode, and compatibility with SPI Modes 0 and 3 in commercial temperature range (0°C to +70°C).
Technical Context
The SST25PF080B-80-4C-QAE-T implements a four-wire SPI interface with dedicated CE#, SCK, SI, SO, WP#, and HOLD# signals, 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 features dual end-of-write detection-software polling of BUSY bit (Status Register Bit 0) and hardware RY/BY# output on SO during AAI programming via EBSY/DBSY commands. Memory is organized into uniform 4 KByte sectors, 32 KByte overlay blocks, and 64 KByte overlay blocks, with block protection controlled by BP2–BP0 bits and lock-down enabled by BPL when WP# is low.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 8 Mbit (1 MByte), directly addressable up to 0xFFFFF; supports wrap-around reads. |
| Supply Voltage | 2.3–3.6 V; enables direct interfacing with 2.5 V and 3.3 V logic without level shifting. |
| Max Clock Frequency | 80 MHz at 2.7–3.6 V; enables high-throughput firmware updates and boot code loading. |
| Endurance | 100,000 program/erase cycles (typical); suitable for field-upgradable firmware with frequent reprogramming. |
| Data Retention | >100 years at +25°C; ensures long-term reliability in unpowered storage applications. |
| Erase Granularity | Uniform 4 KByte sectors, 32 KByte blocks, 64 KByte blocks; allows precise firmware partitioning and OTA update management. |
| Active Read Current | 10 mA (typical at 80 MHz); enables low-power operation in battery-backed or energy-constrained systems. |
| Standby Current | 5 μA (typical); minimizes quiescent power draw during system sleep modes. |
Pinout & Package
Package: 8-lead SOIC (200 mils), RoHS-compliant, surface-mount.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CE# | Chip Enable | Active-low device select; must remain low throughout command sequences; deassertion returns device to standby. |
| SO | Serial Data Output | Outputs read data on falling SCK edge; reconfigurable as RY/BY# status indicator during AAI programming. |
| WP# | Write Protect | Enables/disables BPL bit lock-down; when low, restricts modification of block protection bits unless BPL = 0. |
| VSS | Ground | Reference return path for all digital and analog circuitry; requires low-impedance PCB connection. |
| VDD | Power Supply | 2.3–3.6 V supply input; decoupling capacitor (0.1 μF) recommended near pin for noise suppression. |
| HOLD# | Hold Control | Suspends ongoing SPI transaction without resetting internal state; requires CE# active low and synchronized SCK edge. |
| SCK | Serial Clock | Timing reference for all SPI transfers; sampled on rising edge for inputs, drives outputs on falling edge. |
| SI | Serial Data Input | Accepts commands, addresses, and data; latched on rising SCK edge; high-impedance when not selected. |
Key Features
| Feature | Design Value |
|---|---|
| Auto Address Increment (AAI) Programming | Reduces total programming time by eliminating repeated address transmission for sequential word writes. |
| Hardware End-of-Write Detection | SO pin outputs real-time RY/BY# status during AAI mode (enabled via EBSY command), eliminating software polling overhead. |
| Flexible Block Protection | Configurable via Status Register BP2–BP0 bits to protect 1/16 to full array; lock-down enabled by WP# + BPL bit. |
| Security ID (Sec ID) | 256-bit space: factory-programmed 64-bit unique ID + user-programmable 192-bit segment, lockable permanently via Lockout SID command. |
| High-Speed Read Support | 80 MHz read throughput (2.7–3.6 V) using High-Speed Read instruction (0BH) with dummy cycle, enabling fast boot execution. |
| Low-Power Standby | 5 μA typical current draw in standby; critical for always-on IoT nodes and battery-powered edge devices. |

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-80-4C-QAE-T | Direct successor; identical pinout, timing, and command set; improved manufacturing yield and extended lifecycle support. | Same use cases; preferred for new designs due to active status and guaranteed supply continuity. | Select SST25VF080B-80-4C-QAE-T for new designs; SST25PF080B-80-4C-QAE-T remains viable for legacy repair or obsolescence bridging. |
| AT25DF081A-SH-B | 8 Mbit SPI flash; supports 85 MHz max clock; lacks Security ID and AAI programming; different status register layout. | Requires redesign of protection and programming routines; no hardware RY/BY# on SO pin. | Choose only if AAI and Sec ID are unnecessary and higher clock speed justifies firmware adaptation effort. |
Compared with SST25VF080B-80-4C-QAE-T, the SST25PF080B-80-4C-QAE-T offers identical functionality but is marked obsolete; compared with AT25DF081A-SH-B, it provides superior security and programming efficiency at the cost of vendor-specific feature lock-in.

FAQ
What is the operating voltage range for the SST25PF080B-80-4C-QAE-T?
The SST25PF080B-80-4C-QAE-T operates from 2.3 V to 3.6 V. At 2.3–2.7 V, maximum clock frequency is 50 MHz; at 2.7–3.6 V, it supports up to 80 MHz. This single-supply range eliminates need for external voltage translation when interfacing with common 2.5 V or 3.3 V microcontrollers, and the SST25PF080B-80-4C-QAE-T maintains full functionality-including AAI programming and hardware RY/BY#-across the entire voltage window.
Does the SST25PF080B-80-4C-QAE-T support SPI Mode 3?
Yes, the SST25PF080B-80-4C-QAE-T fully supports both SPI Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1). In Mode 3, SCK idles high, and data is sampled on the rising edge of SCK for SI and shifted out on the falling edge for SO. The SST25PF080B-80-4C-QAE-T requires no configuration to operate in either mode-compatibility is inherent in its physical interface design and command protocol.
How does the HOLD# pin function on the SST25PF080B-80-4C-QAE-T?
The HOLD# pin on the SST25PF080B-80-4C-QAE-T suspends an active SPI transaction without deselecting the device or resetting internal state. It requires CE# to be held low and synchronizes with SCK's active-low state: HOLD# falling edge aligned with SCK low initiates hold; rising edge aligned with SCK low exits hold. During hold, SO enters high-impedance while SI and SCK may float. This behavior is defined in the SST25PF080B-80-4C-QAE-T datasheet and enables seamless bus arbitration in multi-master systems.
Can the SST25PF080B-80-4C-QAE-T be used for secure firmware storage?
Yes-the SST25PF080B-80-4C-QAE-T includes a 256-bit Security ID with factory-programmed 64-bit unique identifier and user-programmable 192-bit segment. The user portion can be programmed once via Program SID command and permanently locked with Lockout SID, preventing further writes. Combined with software block protection (BP2–BP0) and hardware WP#-enabled lock-down, the SST25PF080B-80-4C-QAE-T supports tamper-resistant firmware storage compliant with basic secure boot requirements.
Is the SST25PF080B-80-4C-QAE-T still recommended for new designs?
No-the SST25PF080B-80-4C-QAE-T is marked obsolete by Microchip, with SST25VF080B-80-4C-QAE-T as its direct, pin- and function-compatible replacement. While the SST25PF080B-80-4C-QAE-T remains available for legacy repair and continuity, new designs should adopt the SST25VF080B-80-4C-QAE-T to ensure long-term supply, technical support, and access to updated errata and application notes.
