Product details
Overview
SST25PF020B-80-4C-SAE from Microchip Technology is a 2-Mbit SPI serial Flash memory IC designed for embedded firmware storage and code execution in space-constrained systems. It operates from 2.3V–3.6V, supports 80 MHz clock frequency (at ≥2.7V), delivers 10 mA typical active read current, and features uniform 4-Kbyte sectors with 100,000-cycle endurance - deployed in industrial control panels requiring reliable boot code retention.
For engineers reviewing the SST25PF020B-80-4C-SAE datasheet, SST25PF020B-80-4C-SAE pinout, SST25PF020B-80-4C-SAE application, or SST25PF020B-80-4C-SAE equivalent, key selection criteria include SPI Mode 0/3 compatibility, AAI programming support, HOLD#/WP# hardware protection, 8-lead SOIC package footprint, and commercial temperature range (0°C to +70°C) compliance.
Technical Context
The SST25PF020B-80-4C-SAE implements a four-wire SPI interface with dual-mode clocking (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) and lower total energy per operation versus conventional Flash.
Internal architecture includes dedicated I/O buffers, X/Y decoders, and a programmable STATUS register with BUSY/WEL/AAI/BP bits plus a separate STATUS Register 1 for top/bottom sector protection. Hardware end-of-write detection is supported via SO pin reconfiguration (EBSY/DBSY commands) during Auto Address Increment programming.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 2 Mbit (262,144 × 8-bit), organized as uniform 4-Kbyte sectors |
| Supply Voltage | 2.3V–3.6V - enables direct integration with 2.5V/3.3V logic domains without level-shifting |
| Max Clock Frequency | 80 MHz at 2.7V–3.6V - supports high-throughput firmware updates and XIP-capable boot loading |
| Endurance | 100,000 program/erase cycles - sufficient for field-upgradable firmware with infrequent rewrites |
| Data Retention | >100 years - ensures long-term reliability in unpowered storage applications |
| Active Read Current | 10 mA typical - minimizes power budget impact during active code fetch operations |
| Standby Current | 5 µA typical - critical for low-power sleep modes in battery-backed systems |
| Erase Granularity | 4-Kbyte sectors, 32-Kbyte blocks, 64-Kbyte blocks - enables fine-grained firmware partitioning and OTA update efficiency |
Pinout & Package
Package: 8-Lead SOIC (150 mils), also available in 8-contact USON (3 mm × 2 mm) and WSON (6 mm × 5 mm); this variant SST25PF020B-80-4C-SAE uses the standard SOIC package.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CE# | Chip Enable | Active-low device select - must remain low throughout command sequences; deassertion halts ongoing operations |
| SO | Serial Data Output | Outputs data on SCK falling edge; reconfigurable as RY/BY# status pin during AAI programming |
| WP# | Write Protect | Enables lock-down of STATUS register BP bits - prevents accidental firmware corruption when held low |
| 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 - bypass capacitor required near pin for stable read/write timing |
| HOLD# | Hold Control | Suspends SPI communication without resetting internal state - useful for interrupt-driven host systems |
| SCK | Serial Clock | Timing reference for SI/SO transfers; supports both Mode 0 (idle low) and Mode 3 (idle high) |
| SI | Serial Data Input | Accepts commands, addresses, and data on SCK rising edge - latched synchronously for robust noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Auto Address Increment (AAI) Programming | Reduces multi-byte programming time by eliminating repeated address transmission - improves firmware update throughput by ~40% vs. Byte Program mode |
| Hardware End-of-Write Detection | SO pin outputs real-time RY/BY# status during AAI - eliminates software polling overhead and simplifies host driver design |
| Dual SPI Mode Support (0 and 3) | Ensures compatibility with legacy and modern MCU SPI peripherals without hardware modification |

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 density, 85 MHz max clock, 2.7V–3.6V supply, supports SPI Mode 0 only | Lacks HOLD# pin and AAI programming; no hardware RY/BY# output on SO | Choose when higher clock speed is prioritized over suspend capability and advanced programming efficiency |
| W25Q20EWUXIE | 2-Mbit density, 104 MHz max clock, 1.7V–2.0V/2.7V–3.6V dual-voltage support, Quad SPI capable | Requires Quad SPI controller; lacks native HOLD# functionality; different STATUS register layout | Choose when system already uses Quad SPI infrastructure and ultra-low voltage operation is required |
Compared with AT25DF021A-SSH-T and W25Q20EWUXIE, the SST25PF020B-80-4C-SAE uniquely balances 80 MHz performance, hardware suspend (HOLD#), AAI acceleration, and dual-mode SPI compatibility - making it optimal for cost-sensitive industrial designs needing robust feature parity without Quad SPI complexity.

FAQ
What is the maximum clock frequency supported by the SST25PF020B-80-4C-SAE?
The SST25PF020B-80-4C-SAE supports up to 80 MHz when operating within the 2.7V–3.6V supply range, and 50 MHz at 2.3V–2.7V. This dual-speed capability allows designers to optimize performance versus power consumption based on system voltage rail constraints. The 80 MHz rating is validated per DS20005135C and applies specifically to the SST25PF020B-80-4C-SAE variant.
Does the SST25PF020B-80-4C-SAE support both SPI Mode 0 and Mode 3?
Yes, the SST25PF020B-80-4C-SAE 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 official datasheet. This dual-mode compatibility ensures interoperability with a broad range of microcontroller SPI peripherals without requiring hardware-level clock polarity or phase adjustments. The SST25PF020B-80-4C-SAE maintains full functionality in either mode.
How does the HOLD# pin function on the SST25PF020B-80-4C-SAE?
The HOLD# pin on the SST25PF020B-80-4C-SAE suspends ongoing SPI communication without resetting internal state or requiring CE# deassertion. When activated (HOLD# low while CE# is low and SCK is low), SO enters high-impedance and SI/SCK are ignored until HOLD# returns high. This enables deterministic interrupt handling in real-time systems. The behavior is fully documented for the SST25PF020B-80-4C-SAE in Figure 4-2 and Section 4.1.
What erase options are available on the SST25PF020B-80-4C-SAE?
The SST25PF020B-80-4C-SAE supports three erase granularities: uniform 4-Kbyte sectors (20H command), 32-Kbyte overlay blocks (52H), and 64-Kbyte overlay blocks (D8H), plus full-chip erase (60H/C7H). All erase operations are self-timed and verify automatically. Sector erase takes 18 ms typical; chip erase completes in 35 ms typical. These capabilities are intrinsic to the SST25PF020B-80-4C-SAE's memory architecture and verified in Table 5-1 and Section 5.7.
Is the SST25PF020B-80-4C-SAE RoHS compliant?
Yes, the SST25PF020B-80-4C-SAE is RoHS compliant, as stated in the "Features" section of DS20005135C. This compliance covers lead-free terminations and restricted substance limits per Directive 2011/65/EU. The SST25PF020B-80-4C-SAE meets JEDEC J-STD-020 moisture sensitivity level 3 and is qualified for commercial temperature operation (0°C to +70°C).
