Product details
Overview
SST25VF016B-75-4I-S2AF from Microchip Technology is a 16 Mbit SPI Serial Flash memory IC designed for embedded firmware storage and code execution in resource-constrained systems. It operates from a single 2.7–3.6 V supply, supports up to 80 MHz clock frequency, delivers 100,000 program/erase cycles, and guarantees >100 years data retention - enabling reliable boot code and configuration storage in industrial controllers and IoT edge nodes.
For engineers reviewing the SST25VF016B-75-4I-S2AF datasheet, SST25VF016B-75-4I-S2AF pinout, SST25VF016B-75-4I-S2AF application, or SST25VF016B-75-4I-S2AF equivalent, key selection criteria include SPI Mode 0/3 compatibility, 4 KByte sector erase granularity, Auto Address Increment (AAI) programming efficiency, HOLD#/WP# hardware control support, and industrial temperature range (-40°C to +85°C) operation.
Technical Context
The SST25VF016B-75-4I-S2AF implements a four-wire SPI interface (SCK, SI, SO, CE#) with dual-mode clock polarity support (Mode 0 and Mode 3), enabling seamless integration with diverse microcontroller SPI peripherals. Its SuperFlash technology uses split-gate cells and thick-oxide tunneling injectors to achieve faster erase times and lower active current versus conventional NOR flash.
It features dedicated hardware control pins - HOLD# for pausing ongoing serial transfers without deselecting the device, and WP# for enabling status register lock-down - alongside software-controlled block protection (BP3–BP0) and end-of-write detection via BUSY bit polling or SO-driven RY/BY# output during AAI programming.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (2 MByte) organized as uniform 4 KByte sectors, 32 KByte and 64 KByte overlay blocks |
| Interface | SPI-compatible 4-wire serial interface (SCK, SI, SO, CE#); supports both Mode 0 and Mode 3 |
| Max Clock Frequency | 80 MHz for High-Speed Read and all Write/Erase operations - enables fast firmware loading and OTA updates |
| Supply Voltage | 2.7–3.6 V single supply - compatible with 3.3 V logic systems and simplifies power design |

| WP# | Write Protect | Enables/disables BPL bit lock-down; controls software block protection write access to status register |
| VSS | Ground | Reference return path for all I/O and core circuitry - requires low-impedance PCB connection |
| VDD | Power Supply | 2.7–3.6 V supply input - decoupling capacitor (0.1 µF) recommended near pin for noise immunity |
| HOLD# | Hold | Pauses ongoing SPI transfer without resetting internal state - allows host CPU to service interrupts mid-sequence |
| SCK | Serial Clock | Timing reference for all SPI transactions; sampled on rising edge for inputs, drives outputs on falling edge |
| SI | Serial Data Input | Accepts commands, addresses, and data on rising SCK edge - supports MSB-first 8-bit instruction framing |
Key Features
| Feature | Design Value |
|---|---|
| Auto Address Increment (AAI) Programming | Reduces total programming time by eliminating address retransmission between consecutive word writes - critical for fast firmware patching |
| Flexible Erase Architecture | Independent 4 KByte sector, 32 KByte block, and 64 KByte block erase options - enables precise update zones without full chip erase |
| Hardware End-of-Write Detection | SO pin outputs RY/BY# status during AAI mode (via EBSY/DBSY commands) - eliminates software polling overhead and improves real-time responsiveness |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPI serial flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Winbond W25Q16JV-IQ | 16 Mbit, 104 MHz max clock, Quad SPI support, no HOLD# pin, different status register layout | Lacks HOLD# and native AAI; requires software-managed address incrementing - increases host CPU load during bulk writes | Prefer when Quad SPI bandwidth is required and HOLD# functionality is not needed; verify BP bit mapping differs from SST25VF016B-75-4I-S2AF |
| Macronix MX25L1606E-M2I-12G | 16 Mbit, 80 MHz max clock, standard SPI only, identical pinout and HOLD#/WP# functions, but 50,000-cycle endurance | Lower endurance rating and no AAI programming - limits suitability for frequent field updates | Acceptable for static firmware storage where update frequency is low; not recommended for devices requiring >50,000 field updates |
Compared with Winbond W25Q16JV-IQ and Macronix MX25L1606E-M2I-12G, the SST25VF016B-75-4I-S2AF uniquely combines industrial temperature rating, HOLD# pin support, Auto Address Increment programming, and 100,000-cycle endurance - making it optimal for update-intensive, mission-critical embedded systems.

FAQ
What is the maximum operating frequency of the SST25VF016B-75-4I-S2AF?
The SST25VF016B-75-4I-S2AF supports up to 80 MHz for High-Speed Read, Sector-Erase, Block-Erase, Chip-Erase, Byte-Program, and AAI-Word-Program operations. This is confirmed in Table 5 of DS25044A, where all instructions list "80 MHz" under Maximum Frequency - enabling fast firmware reads and efficient field updates without compromising timing margins.
Does the SST25VF016B-75-4I-S2AF support both SPI Mode 0 and Mode 3?
Yes, the SST25VF016B-75-4I-S2AF explicitly supports both SPI Mode 0 (CPOL = 0, CPHA = 0) and Mode 3 (CPOL = 1, CPHA = 1), as stated in the "Features" section and detailed in Figure 3 of DS25044A. This dual-mode compatibility ensures interoperability with a wide range of microcontroller SPI peripherals without requiring hardware redesign.
What package type does the SST25VF016B-75-4I-S2AF use?
The SST25VF016B-75-4I-S2AF is packaged in an 8-lead SOIC (200 mils) - confirmed in the "Packages Available" feature list and Figure 2 of DS25044A. This surface-mount package offers proven manufacturability, thermal performance, and compatibility with standard reflow profiles used in industrial PCB assembly.
How does the HOLD# pin function on the SST25VF016B-75-4I-S2AF?
The HOLD# pin on the SST25VF016B-75-4I-S2AF suspends an ongoing SPI transaction without deselecting the device or resetting internal state. As described in Section 6 of DS25044A, HOLD# activation requires CE# to be low, and the device enters Hold mode when HOLD# falls coincident with SCK low - allowing host processors to service interrupts while preserving command context.
What is the endurance specification for the SST25VF016B-75-4I-S2AF?
The SST25VF016B-75-4I-S2AF guarantees 100,000 program/erase cycles (typical), as specified in the "Superior Reliability" feature list and reinforced in Section 7.1 of DS25044A. This endurance level supports frequent firmware updates in field-deployed equipment such as network routers and programmable logic controllers.
