Product details

Overview

SST25PF080B-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 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 modules and IoT edge nodes.

For engineers reviewing the SST25PF080B-80-4C-S2AE-T datasheet, SST25PF080B-80-4C-S2AE-T pinout, SST25PF080B-80-4C-S2AE-T application, or SST25PF080B-80-4C-S2AE-T equivalent, key selection considerations include SPI Mode 0/3 compatibility, hardware HOLD#/WP# support for real-time command suspension and sector-level write protection, AAI programming efficiency, and RoHS-compliant 8-lead SOIC (200 mil) packaging.

Technical Context

The SST25PF080B-80-4C-S2AE-T implements a four-wire SPI interface with dual-mode clock polarity (Mode 0 and Mode 3), enabling interoperability with diverse host controllers. Its SuperFlash technology uses split-gate cells and thick-oxide tunneling injectors to achieve faster erase times (18 ms sector-erase, 35 ms chip-erase) and lower active current (10 mA typical) versus conventional NOR flash.

It integrates configurable hardware control pins (HOLD# for serial transaction suspension without CE# toggling, WP# for BPL bit enable/disable), software-managed block protection (BP2–BP0 bits), and dual end-of-write detection - via BUSY-bit polling or SO pin reconfiguration as RY/BY# 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/Program Endurance	100,000 cycles (typical) - sufficient for field-upgradable firmware with frequent patch cycles.
Data Retention	Greater than 100 years - ensures long-term reliability in unattended industrial deployments.
Active Read Current	10 mA (typical at 80 MHz) - minimizes power impact during active code execution from flash.
Standby Current	5 μA (typical) - enables ultra-low-power sleep modes in battery-backed 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 sequences; high-to-low transition initiates instruction acceptance.
SO	Serial Data Output	Outputs read data on falling SCK edge; reconfigurable as RY/BY# status indicator during AAI programming when EBSY command issued.
WP#	Write Protect	Enables/disables lock-down of Block-Protection-Lock (BPL) bit; controls whether BP2–BP0 bits are writable in status register.
VSS	Ground	Reference return path for all digital and analog circuitry; requires low-impedance PCB connection.
VDD	Power Supply	2.3–3.6V input; decoupling capacitor (0.1 μF) recommended within 5 mm of pin for noise immunity.
HOLD#	Hold Control	Suspends ongoing SPI sequence without deselecting device; allows host to service higher-priority interrupts while preserving internal state.
SCK	Serial Clock	Timing reference for SI/SO transfers; rising edge latches input, falling edge outputs data; supports Mode 0 (idle low) and Mode 3 (idle high).
SI	Serial Data Input	Accepts commands, addresses, and data MSB-first on rising SCK edge; high-impedance when CE# is high.

Key Features

Feature	Design Value
Auto Address Increment (AAI) Programming	Reduces multi-byte programming time by eliminating repeated address transmission - critical for fast firmware image writes.
Hardware End-of-Write Detection (EBSY/DBSY)	Reconfigures SO pin as RY/BY# during AAI mode, enabling interrupt-driven completion signaling instead of CPU-intensive BUSY polling.
Flexible Block Protection	Software-configurable BP2–BP0 bits protect 1/16 to full array; BPL bit (enabled by WP#) locks protection settings against accidental overwrite.
Security ID (Sec ID)	256-bit space: factory-programmed 64-bit unique ID + user-programmable 192-bit segment - supports secure boot authentication and device binding.
Uniform Erase Architecture	Independent 4 KByte sector, 32 KByte block, and 64 KByte block erase - allows precise wear leveling and partial firmware updates.

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-70-4C-S2AE-T	Successor part with identical pinout, same 8 Mbit density and SOIC-8 (200 mil) package, but rated for 70 MHz max read speed and updated process node.	Same industrial temperature range (0°C to +70°C); improved parametric consistency and extended product lifecycle.	Select SST25VF080B-70-4C-S2AE-T for new designs - it supersedes SST25PF080B-80-4C-S2AE-T per Microchip documentation and offers longer-term availability.
AT25DF081-SSH-T	8 Mbit SPI flash from Adesto (now Dialog Semiconductor); supports 85 MHz read, Quad SPI option, but lacks HOLD# pin and AAI programming.	Requires different driver stack due to absence of HOLD# and AAI; no hardware RY/BY# output on SO pin.	Use only if Quad SPI bandwidth is required and host controller supports alternate command set; not drop-in compatible due to missing HOLD# and differing status register layout.

Compared with SST25VF080B-70-4C-S2AE-T, the SST25PF080B-80-4C-S2AE-T offers marginally higher 80 MHz read speed but is obsolete; compared with AT25DF081-SSH-T, it provides superior real-time control via HOLD# and more efficient programming via AAI, at the cost of lower maximum frequency and no Quad SPI support.

FAQ

What is the operating voltage range for the SST25PF080B-80-4C-S2AE-T?

The SST25PF080B-80-4C-S2AE-T operates from a single supply of 2.3V to 3.6V. At 2.7–3.6V, it achieves its maximum 80 MHz read speed; at 2.3–2.7V, maximum read speed is reduced to 50 MHz. This wide voltage range allows direct interfacing with both 2.5V and 3.3V system rails without level-shifting circuitry.

Does the SST25PF080B-80-4C-S2AE-T support SPI Mode 0 and Mode 3?

Yes, the SST25PF080B-80-4C-S2AE-T fully supports both SPI Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1). In both modes, SI data is sampled on the rising edge of SCK, and SO data is driven on the falling edge. The difference lies only in the idle state of SCK - low in Mode 0, high in Mode 3 - ensuring compatibility with diverse host controllers.

How does the HOLD# pin function on the SST25PF080B-80-4C-S2AE-T?

The HOLD# pin on the SST25PF080B-80-4C-S2AE-T suspends an ongoing SPI transaction without deselecting the device or resetting internal state. When asserted low while CE# is active, it places SO in high-impedance and pauses clock synchronization. Communication resumes immediately upon deasserting HOLD#, allowing the host MCU to handle urgent interrupts without aborting flash operations.

What is the purpose of the Security ID feature in the SST25PF080B-80-4C-S2AE-T?

The SST25PF080B-80-4C-S2AE-T includes a 256-bit Security ID (Sec ID) with a factory-programmed 64-bit unique identifier and a user-programmable 192-bit segment. Once locked via the Lockout SID command, the entire Sec ID becomes read-only. This enables secure boot verification, device authentication, and anti-cloning measures in regulated applications like medical and industrial systems.

Is the SST25PF080B-80-4C-S2AE-T still recommended for new designs?

No - the SST25PF080B-80-4C-S2AE-T is marked obsolete by Microchip. The recommended replacement is the SST25VF080B-70-4C-S2AE-T, which shares identical pinout, package, and core functionality but offers improved process yield, extended lifecycle support, and documented long-term availability. Migration requires no PCB changes but may involve minor timing adjustments due to its 70 MHz rating.
