Product details
Overview
SST25VF016B-75-4I-S2AF-T from Microchip Technology is a 16 Mbit SPI Serial Flash memory IC used for non-volatile code and data storage in embedded systems. It operates at 2.7–3.6 V, supports up to 80 MHz clock frequency, features uniform 4 KByte sectors and 32/64 KByte overlay blocks, and delivers 100,000 program/erase cycles with >100 years data retention - deployed in industrial microcontroller boot loaders and firmware update storage.
For engineers reviewing the SST25VF016B-75-4I-S2AF-T datasheet, SST25VF016B-75-4I-S2AF-T pinout, SST25VF016B-75-4I-S2AF-T application, or SST25VF016B-75-4I-S2AF-T equivalent, key selection criteria include SPI Mode 0/3 compatibility, industrial temperature range (−40°C to +85°C), SOIC-8 package footprint, hardware HOLD#/WP# control, and AAI programming efficiency for firmware field updates.
Technical Context
The SST25VF016B-75-4I-S2AF-T implements a four-wire SPI interface (SCK, SI, SO, CE#) with dual-mode timing support (Mode 0 and Mode 3), enabling interoperability with diverse host controllers. Its SuperFlash technology uses split-gate cells and thick-oxide tunneling to achieve faster erase times (18 ms sector-erase typical) and lower active current (10 mA typical) versus conventional flash.
It integrates dedicated control pins - HOLD# for pausing ongoing serial sequences without deselecting, and WP# for enabling status register lock-down - alongside software-managed block protection (BP3–BP0) and Auto Address Increment (AAI) for efficient multi-byte programming. End-of-write detection is supported via both BUSY-bit polling and hardware RY/BY# output on SO during AAI mode.
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 - enables granular firmware partitioning and secure OTA update staging. |
| Interface | SPI-compatible, 4-wire (SCK/SI/SO/CE#), supports Mode 0 and Mode 3 - ensures plug-and-play integration with ARM Cortex-M, PIC, and FPGA SPI masters. |
| Max Clock Frequency | 80 MHz (High-Speed Read) - reduces boot time and firmware load latency in real-time systems. |
| Supply Voltage | 2.7–3.6 V single supply - compatible with 3.3 V system rails without level-shifting. |
| Endurance & Retention | 100,000 program/erase cycles typical; >100 years data retention - suitable for infrequently updated but mission-critical configuration storage. |
| Operating Temperature | −40°C to +85°C (Industrial grade) - validated for deployment in automotive ECUs, industrial HMIs, and outdoor IoT gateways. |
| Active/Standby Current | 10 mA typical read current; 5 µA typical standby current - extends battery life in always-on edge devices. |
Pinout & Package
Package: 8-lead SOIC (200 mils), RoHS-compliant, surface-mountable with standard 1.27 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CE# | Chip Enable | Active-low device select; must remain low throughout command execution - enables multi-device SPI bus sharing with daisy-chained or decoded addressing. |
| SO | Serial Data Output | Tri-state output; shifts data on SCK falling edge; reconfigurable as RY/BY# during AAI programming - supports both standard read and hardware busy signaling without external logic. |
| WP# | Write Protect | Hardware enable for status register lock-down (BPL bit); when low, prevents BP3–BP0 modification unless BPL = 0 - provides tamper-resistant firmware protection. |
| HOLD# | Hold Control | Pauses ongoing SPI transaction without resetting internal state or requiring CE# toggle - preserves command context during interrupt servicing or bus arbitration. |
| SCK | Serial Clock | Timing reference; latches SI on rising edge, drives SO on falling edge - defines deterministic setup/hold timing for reliable high-speed communication. |
| SI | Serial Data Input | Command/address/data input path; MSB-first, synchronous to SCK rising edge - supports full instruction set including WRSR, AAI, and JEDEC-ID read. |
| VDD | Power Supply | 2.7–3.6 V core supply - eliminates need for separate voltage regulators in 3.3 V designs. |
| VSS | Ground | Reference return path - requires low-impedance PCB grounding to maintain signal integrity at 80 MHz. |
Key Features
| Feature | Design Value |
|---|---|
| Auto Address Increment (AAI) Programming | Reduces total programming time by eliminating address retransmission between consecutive bytes - critical for fast field firmware patching. |
| Flexible Erase Architecture | Independent 4 KByte sector, 32 KByte, and 64 KByte block erase - allows selective update of bootloader, app, and config partitions without full chip erase. |
| Hardware End-of-Write Detection | SO pin outputs RY/BY# status during AAI mode (via EBSY/DBSY commands) - removes software polling overhead and improves deterministic timing in safety-critical systems. |
| Software Block Protection | Configurable BP3–BP0 bits protect up to entire memory array; BPL bit locks protection settings - enforces immutable bootloader regions in certified embedded applications. |
| Industrial Temperature Range | Validated operation from −40°C to +85°C - meets extended thermal requirements for motor drives, power inverters, and railway control units. |

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 W25Q16JVSSIQ | 16 Mbit, 104 MHz max clock, Quad SPI support, 1.65–1.95 V or 2.7–3.6 V dual supply options | Supports QSPI x4 mode for higher throughput; lacks HOLD# pin; different status register map and protection scheme | Preferred when system requires >80 MHz read bandwidth or quad I/O interface; not drop-in due to pinout and command set differences. |
| Micron MT25QL128ABA8ESF-0SIT | 128 Mbit density, 133 MHz max clock, 1.7–2.0 V or 2.7–3.6 V supply, built-in security features (OTP, volatile/non-volatile locks) | Higher density and advanced security; no AAI mode; different erase granularity (4 KB sectors only) | Selected for scalable designs needing future capacity headroom or cryptographic key storage; requires PCB redesign and firmware adaptation. |
Compared with SST25VF016B-75-4I-S2AF-T, W25Q16JVSSIQ offers higher speed and quad interface but sacrifices HOLD# functionality and requires command rework, while MT25QL128ABA8ESF-0SIT adds security and density at the cost of AAI efficiency and direct pin compatibility - making SST25VF016B-75-4I-S2AF-T optimal for cost-sensitive, industrial-grade SPI boot storage where simplicity and proven reliability are prioritized.

FAQ
What is the maximum operating frequency of the SST25VF016B-75-4I-S2AF-T?
The SST25VF016B-75-4I-S2AF-T supports up to 80 MHz for High-Speed Read operations using the 0BH command with dummy cycle, and up to 80 MHz for all write/erase instructions including Sector-Erase, Block-Erase, Chip-Erase, and AAI-Word-Program. The "75" in the part number denotes 75 ns access time, consistent with this 80 MHz capability.
Does the SST25VF016B-75-4I-S2AF-T support both SPI Mode 0 and Mode 3?
Yes, the SST25VF016B-75-4I-S2AF-T explicitly supports both SPI Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1), as confirmed in the DS25044A datasheet Section 5. This dual-mode compatibility ensures interoperability with a wide range of microcontrollers and FPGAs without requiring hardware modifications.
What package type is used for the SST25VF016B-75-4I-S2AF-T?
The SST25VF016B-75-4I-S2AF-T is packaged in an 8-lead SOIC (200 mils) with 1.27 mm lead pitch, as specified in the DS25044A datasheet Figure 2 and Package Options table. The "S2AF" suffix confirms the SOIC-8 industrial-grade variant.
How does the HOLD# pin function on the SST25VF016B-75-4I-S2AF-T?
The HOLD# pin on the SST25VF016B-75-4I-S2AF-T suspends an ongoing SPI transaction without deselecting the device or resetting internal state. When asserted low during active CE#, it places SO in high-impedance while preserving command context - enabling seamless interruption handling in real-time systems without reinitializing the serial sequence.
What is the purpose of Auto Address Increment (AAI) programming in the SST25VF016B-75-4I-S2AF-T?
AAI programming in the SST25VF016B-75-4I-S2AF-T allows sequential word programming without retransmitting the address for each word, reducing total programming time significantly. Initiated with command ADH, it accepts two data bytes per command and auto-increments the address - ideal for rapid firmware image writes where minimizing host CPU overhead is critical.
