Product details
Overview
SST25PF020B-80-4C-SAE-T from Microchip Technology is a 2-Mbit SPI serial Flash memory IC operating at 2.3V–3.6V, supporting 80 MHz clock frequency (at 2.7V–3.6V), featuring uniform 4-Kbyte sectors and Auto Address Increment (AAI) programming. It delivers 100,000 write/erase cycles and >100 years data retention for embedded firmware storage in microcontroller-based systems.
For engineers reviewing the SST25PF020B-80-4C-SAE-T datasheet, SST25PF020B-80-4C-SAE-T pinout, SST25PF020B-80-4C-SAE-T application, or SST25PF020B-80-4C-SAE-T equivalent, key selection considerations include SPI Mode 0/3 compatibility, 8-lead SOIC/WSON/USON package options, sector/block erase flexibility, low 5 µA standby current, and hardware/software write protection with HOLD#/WP# pins.
Technical Context
The SST25PF020B-80-4C-SAE-T implements a four-wire SPI interface with dual-mode support (Mode 0 and Mode 3), using CE#, SCK, SI, and SO signals for command, address, and data transfer. Its SuperFlash® technology enables fast erase (18 ms sector, 35 ms chip) and byte program (7 µs) with single-supply operation.
It integrates dual software status registers: STATUS register (BUSY, WEL, BP0/BP1, BPL, AAI bits) and STATUS Register 1 (TSP/BSP) for granular memory protection. End-of-write detection is supported via BUSY bit polling or hardware RY/BY# output on SO during AAI mode when enabled by EBSY (70H) command.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 2 Mbit (262,144 bytes), organized as uniform 4-Kbyte sectors |
| Supply Voltage | 2.3V–3.6V - enables direct interfacing with 2.5V/3.3V logic without level shifters |
| Max Clock Frequency | 80 MHz at 2.7V–3.6V - supports high-throughput firmware updates and boot code loading |
| Erase Time (Sector) | 18 ms typical - reduces firmware field update latency compared to standard SPI Flash |
| Program Time (Byte) | 7 µs typical - accelerates small-packet configuration writes in real-time systems |
| Data Retention | >100 years - ensures long-term reliability in unattended industrial deployments |
| Endurance | 100,000 cycles typical - suitable for logging, parameter storage, and infrequent firmware patching |
| Standby Current | 5 µA typical - minimizes power budget impact in battery-backed or energy-sensitive applications |
Pinout & Package
Package: 8-Lead SOIC (150 mil), also available in 8-contact USON (3 mm × 2 mm) and WSON (6 mm × 5 mm). This entry corresponds to the -SAE-T variant, which uses the 8-Lead SOIC package.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CE# | Chip Enable | Active-low device select; must remain low throughout command sequence to prevent premature termination |
| SO | Serial Data Output | Outputs read data on falling SCK edge; reconfigurable as RY/BY# during AAI mode for hardware busy signaling |
| WP# | Write-Protect | Enables lock-down of Block Protection Lock (BPL) bit; controls software write protection granularity |
| VSS | Ground | Reference return path for all digital and analog circuitry; requires low-impedance PCB connection |
| VDD | Power Supply | 2.3V–3.6V supply input; decoupling capacitor (0.1 µF) recommended near pin |
| HOLD# | Hold Control | Suspends ongoing SPI transaction without deselecting device; preserves internal state and address pointer |
| SCK | Serial Clock | Timing reference for SI/SO; rising edge latches input, falling edge shifts out output (Mode 0/3 compatible) |
| SI | Serial Data Input | Accepts opcodes, addresses, and data; sampled on rising SCK edge per SPI protocol |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash® Technology | Enables lower program/erase current and shorter timing vs. conventional Flash, reducing total energy per operation |
| Auto Address Increment (AAI) | Eliminates repeated address transmission during multi-byte programming, cutting SPI bus overhead by ~50% for sequential writes |
| Dual Status Registers | STATUS register controls BP0/BP1/BPL; STATUS Register 1 adds independent Top/Bottom Sector Protection (TSP/BSP) for secure partitioning |
| Hardware Busy Signaling | SO pin repurposed as RY/BY# during AAI mode (via EBSY command), enabling interrupt-driven write completion detection |
| Flexible Erase Granularity | Supports 4-Kbyte sector, 32-Kbyte block, and 64-Kbyte block erase - optimizes wear leveling and firmware delta updates |
| HOLD# and WP# Pins | Allow runtime suspension of SPI sequences and hardware-enforced write lockdown, critical for fail-safe system recovery |

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 |
|---|---|---|---|
| AT25DF021A-SSH-T | 2 Mbit, 85 MHz max clock, 2.7V–3.6V supply, no AAI mode, different status register layout | Lacks Auto Address Increment and dual-status register; uses simpler BP0/BP1-only protection | Preferred where legacy SPI driver compatibility is prioritized over advanced programming efficiency |
| W25Q20EWUXIE | 2 Mbit, 104 MHz max clock, 1.65V–3.6V supply, Quad SPI support, AAI not supported | Supports QPI/DTR modes for higher bandwidth; wider voltage range but no HOLD#/WP#-enhanced safety features | Chosen when system requires quad-interface scalability or ultra-low-voltage operation below 2.3V |

FAQ
What is the maximum clock frequency supported by the SST25PF020B-80-4C-SAE-T?
The SST25PF020B-80-4C-SAE-T supports up to 80 MHz clock frequency when operating within the 2.7V–3.6V supply range. At lower voltages (2.3V–2.7V), the maximum clock frequency is reduced to 50 MHz. This dual-speed capability ensures compatibility with both high-performance and low-voltage system designs while maintaining reliable SPI communication integrity.
Does the SST25PF020B-80-4C-SAE-T support both SPI Mode 0 and Mode 3?
Yes, the SST25PF020B-80-4C-SAE-T explicitly supports both SPI Mode 0 (CPOL = 0, CPHA = 0) and Mode 3 (CPOL = 1, CPHA = 1), as confirmed in its official datasheet. This dual-mode compatibility allows seamless integration with diverse host microcontrollers - including those with fixed SPI polarity/phase settings - without requiring external signal conditioning or protocol translation.
How does the HOLD# pin function during active SPI communication in the SST25PF020B-80-4C-SAE-T?
The HOLD# pin in the SST25PF020B-80-4C-SAE-T suspends an ongoing SPI transaction without resetting internal state or address pointers. When asserted low (with CE# active), it places SO in high-impedance while allowing SI and SCK to remain idle. Communication resumes upon de-asserting HOLD# and maintaining CE# low, preserving command context - essential for time-critical interrupt handling in real-time embedded firmware.
What erase block sizes are available on the SST25PF020B-80-4C-SAE-T?
The SST25PF020B-80-4C-SAE-T supports three erase granularities: uniform 4-Kbyte sectors, 32-Kbyte overlay blocks, and 64-Kbyte overlay blocks. These options are selected via distinct opcodes (20H, 52H, D8H) and enable optimized wear leveling, partial firmware updates, and efficient memory management - unlike devices limited to single-block-size erase operations.
Is the SST25PF020B-80-4C-SAE-T RoHS compliant?
Yes, the SST25PF020B-80-4C-SAE-T is RoHS compliant, as explicitly stated in its official Microchip datasheet (DS20005135C). This compliance confirms that the device meets EU Directive 2011/65/EU requirements for restriction of hazardous substances, including lead, mercury, cadmium, hexavalent chromium, PBB, and PBDE, making it suitable for global commercial and industrial deployments.
