Product details
Overview
SST25PF080B-80-4C-SAE-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 from a single 2.3–3.6V supply, supports 80 MHz read speed (at 2.7–3.6V), features uniform 4 KByte sectors and 64 KByte overlay blocks, and delivers 100,000 program/erase cycles with >100 years data retention - deployed in industrial control boot loaders and IoT sensor firmware images.
For engineers reviewing the SST25PF080B-80-4C-SAE-T datasheet, SST25PF080B-80-4C-SAE-T pinout, SST25PF080B-80-4C-SAE-T application, or SST25PF080B-80-4C-SAE-T equivalent, key selection criteria include SPI Mode 0/3 compatibility, hardware hold/resume capability via HOLD# pin, software block protection granularity (BP2–BP0), AAI programming efficiency, and RoHS-compliant 8-lead SOIC (200 mil) packaging.
Technical Context
The SST25PF080B-80-4C-SAE-T implements a four-wire SPI interface with dual-mode clock polarity support (Mode 0 and Mode 3), enabling interoperability with diverse microcontroller host interfaces. Its SuperFlash technology uses split-gate cells and thick-oxide tunneling injectors to achieve faster erase times (18 ms sector-erase typical) and lower active current (10 mA typical) versus conventional NOR flash.
It integrates dedicated control pins - HOLD# for pausing ongoing SPI sequences without CE# deassertion, and WP# for enabling status register lock-down - alongside dual end-of-write detection: software polling of BUSY bit and hardware RY/BY# output on SO during Auto Address Increment (AAI) programming.
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 granular firmware updates without full chip erase. |
| Supply Voltage | 2.3–3.6V single supply - compatible with 2.5V and 3.3V system rails; no external voltage translators required. |
| Max Read Speed | 80 MHz (2.7–3.6V); 50 MHz (2.3–2.7V) - supports high-throughput boot code fetch and configuration loading. |
| Erase Endurance | 100,000 cycles (typical) - sufficient for field firmware upgrades over 10+ years in industrial deployments. |
| Data Retention | >100 years (typical) - ensures long-term reliability in unpowered storage applications. |

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 - enables multi-device SPI bus sharing. |
| SO | Serial Data Output | Tri-state output; shifts data on SCK falling edge; reconfigurable as RY/BY# during AAI mode for hardware busy signaling. |
| WP# | Write Protect | Enables BPL bit lock-down in status register; when low, prevents modification of BP2–BP0 unless BPL=0 - critical for secure firmware write protection. |
| HOLD# | Hold Control | Pauses ongoing SPI transaction without resetting clock state; allows host to service higher-priority interrupts mid-sequence. |
| SCK | Serial Clock | Provides timing reference; samples SI on rising edge, drives SO on falling edge - supports both SPI Mode 0 (SCK idle low) and Mode 3 (SCK idle high). |
| SI | Serial Data Input | Accepts commands, addresses, and data MSB-first; latched on SCK rising edge - ensures deterministic setup/hold timing. |
| VDD | Power Supply | 2.3–3.6V input; powers internal logic and memory array - decoupling capacitor placement near this pin is mandatory for stable operation. |
| VSS | Ground | Reference return path; must be connected to system ground plane with low-impedance trace to minimize noise coupling into SPI signals. |
Key Features
| Feature | Design Value |
|---|---|
| Auto Address Increment (AAI) Programming | Reduces total programming time by eliminating address retransmission for sequential word writes - cuts firmware update duration by ~40% vs. byte-program mode. |
| Flexible Block Protection | Software-configurable BP2–BP0 bits protect memory regions from accidental overwrite - supports partial lockdown of bootloader, config, and application partitions. |
| Hardware End-of-Write Detection | SO pin outputs RY/BY# status during AAI mode (enabled via EBSY command) - eliminates CPU polling overhead and improves real-time responsiveness. |
| Security ID with Lockout | 256-bit factory-programmed + user-programmable segment; once locked via Lockout SID command, prevents further modification - enables device authentication and anti-cloning. |
| Uniform Erase Architecture | Coherent 4 KByte sector / 32 KByte / 64 KByte block granularity - simplifies partitioning logic in bootloader and avoids fragmentation across erase boundaries. |

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 | Successor device with identical pinout, density, and voltage range; improved ECC and enhanced security features per Microchip migration notice. | Supports same industrial and medical applications but adds stronger data integrity assurance for safety-critical firmware. | Select SST25VF080B for new designs requiring extended lifecycle support and enhanced reliability features. |
| W25Q80DVSSIG | 8 Mbit SPI flash from Winbond; supports quad I/O, 104 MHz DTR read, and deeper power-down modes (1 μA). | Better suited for high-speed code execution and ultra-low-power sleep scenarios where quad interface is available. | Choose W25Q80DVSSIG only if host MCU supports QPI and design requires sub-μA standby or faster random reads. |
Compared with SST25VF080B, the SST25PF080B-80-4C-SAE-T lacks ECC and newer security extensions but remains viable for legacy-compatible designs; versus W25Q80DVSSIG, it trades quad interface and lower standby current for simpler SPI-only implementation and proven field reliability in cost-sensitive industrial systems.

FAQ
What is the maximum clock frequency supported by SST25PF080B-80-4C-SAE-T during read operations?
The SST25PF080B-80-4C-SAE-T supports up to 80 MHz read speed when operating within the 2.7–3.6V supply range, and 50 MHz when supplied from 2.3–2.7V. This dual-frequency capability allows designers to optimize performance versus power consumption based on system rail constraints. The 80 MHz rating applies specifically to High-Speed Read (0BH) instruction with dummy cycle, not standard Read (03H).
Does SST25PF080B-80-4C-SAE-T support both SPI Mode 0 and Mode 3?
Yes, the SST25PF080B-80-4C-SAE-T explicitly supports both SPI Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1), as confirmed in Section 4.0 of the datasheet. This dual-mode compatibility ensures seamless integration with a wide range of microcontrollers, including those with fixed SPI polarity settings. The device samples SI on the rising edge and drives SO on the falling edge in both modes.
How does the HOLD# pin function in SST25PF080B-80-4C-SAE-T?
The HOLD# pin in SST25PF080B-80-4C-SAE-T suspends an ongoing SPI transaction without deselecting the device or resetting the clock sequence. When asserted low while CE# is active, it places SO in high-impedance state and pauses communication until HOLD# returns high. This allows the host MCU to service interrupts or manage other peripherals mid-command - a critical feature for real-time deterministic systems using the SST25PF080B-80-4C-SAE-T.
What erase block sizes are available on SST25PF080B-80-4C-SAE-T?
The SST25PF080B-80-4C-SAE-T supports three uniform erase granularities: 4 KByte sectors, 32 KByte overlay blocks, and 64 KByte overlay blocks. Sector-erase uses command 20H with A12 addressing; 32 KByte block-erase uses 52H with A15; 64 KByte block-erase uses D8H with A16. All erase operations require prior WREN and are subject to block protection bit (BP2–BP0) settings - a key design consideration for firmware partitioning in SST25PF080B-80-4C-SAE-T implementations.
Is SST25PF080B-80-4C-SAE-T still recommended for new designs?
No - Microchip explicitly marks SST25PF080B-80-4C-SAE-T as obsolete in the datasheet and recommends SST25VF080B as its direct successor. While SST25PF080B-80-4C-SAE-T remains available for legacy production and repair, new designs should adopt SST25VF080B for continued technical support, extended lifecycle availability, and access to enhanced features like improved ECC and updated security capabilities.
