Product details
Overview
SST25PF020B-80-4C-Q3AE-T from Microchip Technology is a 2-Mbit SPI serial Flash memory IC operating at 2.3V–3.6V, supporting 80 MHz clock frequency (2.7V–3.6V), featuring uniform 4-Kbyte sectors and Auto Address Increment (AAI) programming for embedded firmware storage in microcontroller-based systems.
For engineers reviewing the SST25PF020B-80-4C-Q3AE-T datasheet, SST25PF020B-80-4C-Q3AE-T pinout, SST25PF020B-80-4C-Q3AE-T application, or SST25PF020B-80-4C-Q3AE-T equivalent, key selection considerations include SPI Mode 0/3 compatibility, 100,000-program/erase endurance, 5 µA standby current, software/hardware write protection, and support for high-speed read (0BH) and AAI word programming (ADH).
Technical Context
The SST25PF020B-80-4C-Q3AE-T implements a four-wire SPI interface with dual-mode clocking (Mode 0 and Mode 3), using SuperFlash® split-gate CMOS technology to achieve faster erase times (18 ms sector erase) and lower total energy consumption versus conventional Flash. Its internal architecture includes dedicated I/O buffers, X/Y decoders, and dual-status registers (STATUS and STATUS Register 1) for granular block and top/bottom sector protection.
It supports three end-of-write detection methods: software polling of the BUSY bit, hardware RY/BY# status output on SO during AAI mode (enabled via EBSY command), and fixed timing wait (TBP/TSE). The HOLD# and WP# pins provide hardware-level suspend and lock-down control independent of software state.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 2 Mbit (262,144 bytes), organized as uniform 4-Kbyte sectors, 32-Kbyte and 64-Kbyte overlay blocks |
| Supply Voltage | 2.3V–3.6V - enables direct interfacing with 2.5V/3.3V logic without level-shifting |
| Max Clock Frequency | 80 MHz at 2.7V–3.6V - supports high-throughput firmware updates and boot code loading |

| Data Retention | Greater than 100 years - ensures long-term reliability in unpowered storage applications |
| Active Read Current | 10 mA typical - minimizes power draw during active code execution from Flash |
| Standby Current | 5 µA typical - critical for battery-powered IoT nodes requiring ultra-low quiescent power |
| Erase Time | 18 ms typical for sector/block, 35 ms chip erase - reduces firmware update latency |
Pinout & Package
Package: 8-contact WSON (6 mm × 5 mm), RoHS-compliant, commercial temperature range (0°C to +70°C).
| 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 data on falling SCK edge; reconfigurable as RY/BY# during AAI mode for hardware busy signaling |
| WP# | Write-Protect | Enables BPL bit lock-down in STATUS register; disables software write protection modification when pulled low |
| SI | Serial Data Input | Accepts commands, addresses, and data on rising SCK edge; MSb-first protocol alignment |
| SCK | Serial Clock | Provides timing reference; supports both Mode 0 (SCK idle low) and Mode 3 (SCK idle high) |
| HOLD# | Hold | Suspends ongoing SPI transaction without deselecting device; requires CE# low and synchronized SCK edge |
| VDD | Power Supply | 2.3V–3.6V supply input; powers all internal logic and memory array |
| VSS | Ground | Reference ground for all I/O and core circuitry; must be low-impedance for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Auto Address Increment (AAI) Programming | Reduces multi-byte programming time by eliminating repeated address transmission; supports sequential word writes with single ADH command |
| Dual Status Registers | STATUS register controls BP0/BP1/BPL for block protection; STATUS Register 1 adds independent TSP/BSP bits for top/bottom sector locking |
| Hardware End-of-Write Detection | EBSY (70H) command configures SO pin as RY/BY# output during AAI, enabling real-time busy status without software polling overhead |
| Flexible Erase Granularity | Supports 4-Kbyte sector, 32-Kbyte block, and 64-Kbyte block erase - allows precise firmware partitioning and partial updates |
| High-Speed Read (0BH) | Includes dummy cycle for optimized timing; delivers faster instruction fetch vs. standard read (03H), improving system boot speed |
| SuperFlash® Technology | Split-gate cell design with thick-oxide tunneling injector provides superior endurance and data retention over standard NOR Flash |

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, 2.7V–3.6V supply, supports SPI Mode 0 only; no AAI programming | Lacks AAI and hardware RY/BY#; requires software polling for write completion | Choose when maximum clock speed (85 MHz) is prioritized over programming efficiency and hardware status signaling |
| W25Q20EWUXIE | 2-Mbit, 133 MHz max, 1.65V–3.6V supply, Quad SPI support; includes SFDP for auto-configuration | Supports QSPI and higher bandwidth but requires additional IO lines; no HOLD#/WP# pin-level suspend | Choose when system demands quad-I/O throughput or wider voltage range; avoid if board layout is constrained to 4-wire SPI |
Compared with AT25DF021A-SSH-T and W25Q20EWUXIE, the SST25PF020B-80-4C-Q3AE-T uniquely balances 80 MHz performance, ultra-low 5 µA standby, AAI acceleration, and dual hardware control pins (HOLD#/WP#) - making it optimal for cost-sensitive, power-constrained MCU designs needing robust firmware update capability without QSPI complexity.

FAQ
What is the maximum clock frequency supported by the SST25PF020B-80-4C-Q3AE-T?
The SST25PF020B-80-4C-Q3AE-T supports up to 80 MHz clock frequency when operated 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-frequency specification ensures compatibility with both high-performance and low-voltage system designs while maintaining signal integrity and timing margins.
Does the SST25PF020B-80-4C-Q3AE-T support SPI Mode 3 operation?
Yes, the SST25PF020B-80-4C-Q3AE-T fully supports SPI Mode 3 (CPOL=1, CPHA=1), where the serial clock (SCK) is idle high and data is sampled on the falling edge. It also supports Mode 0 (CPOL=0, CPHA=0). This dual-mode compatibility allows seamless integration with diverse host controllers including legacy and modern MCUs without requiring hardware modifications.
How does the HOLD# pin function in the SST25PF020B-80-4C-Q3AE-T?
The HOLD# pin in the SST25PF020B-80-4C-Q3AE-T suspends an ongoing SPI transaction without resetting the internal state or deselecting the device. When activated (pulled low) during an active CE# session, it places SO in high-impedance while allowing SI and SCK to remain valid. Communication resumes upon deasserting HOLD# while CE# remains low, preserving command context and address pointer position.
What write protection mechanisms are available on the SST25PF020B-80-4C-Q3AE-T?
The SST25PF020B-80-4C-Q3AE-T offers three-tiered write protection: hardware-level via the WP# pin (enabling BPL lock-down), software-level via BP0/BP1 bits in STATUS register (configuring 0–100% memory protection), and sector-level via TSP/BSP bits in STATUS Register 1 (independently locking top/bottom 4-Kbyte sectors). All protections persist through power cycles and require explicit unlock sequences.
Can the SST25PF020B-80-4C-Q3AE-T be used for execute-in-place (XIP) applications?
Yes, the SST25PF020B-80-4C-Q3AE-T supports XIP operation via its high-speed read instruction (0BH), which includes a dummy cycle optimized for timing-critical instruction fetch. With 80 MHz interface speed and low latency, it enables direct code execution from external Flash in microcontrollers that support SPI memory mapping, reducing reliance on limited internal flash resources.
What is the significance of the 'Q3AE' suffix in SST25PF020B-80-4C-Q3AE-T?
The 'Q3AE' suffix in SST25PF020B-80-4C-Q3AE-T indicates the package type and environmental compliance: 'Q' denotes 8-contact WSON (6 mm × 5 mm), '3' specifies commercial temperature range (0°C to +70°C), 'A' signifies RoHS compliance, and 'E' denotes tape-and-reel packaging. The '-T' suffix confirms it is a full-production, lead-free, halogen-free, and REACH-compliant ordering option.
