Overview
SST25VF016B-50-4C-QAF from Microchip Technology is a 16 Mbit SPI serial flash memory IC with quad-wire interface, operating at up to 50 MHz clock frequency, 2.7–3.6 V single supply, and industrial temperature range (–40°C to +85°C). It delivers fast byte-program (7 µs typ), sector/block erase (18 ms typ), and chip-erase (35 ms typ) for firmware storage in microcontroller-based embedded systems.
For engineers reviewing the SST25VF016B-50-4C-QAF datasheet, SST25VF016B-50-4C-QAF pinout, SST25VF016B-50-4C-QAF application, or SST25VF016B-50-4C-QAF equivalent, this page provides verified electrical parameters, SOIC/WSON package mapping, AAI programming support, hardware/software end-of-write detection, and real-world use context for boot code, configuration data, and OTA update storage.
Technical Context
The SST25VF016B-50-4C-QAF implements a four-wire SPI-compatible interface supporting both Mode 0 and Mode 3 timing, with dedicated HOLD# and WP# control pins for suspend and write-lock functionality. Its SuperFlash technology enables high endurance (100,000 program/erase cycles) and >100-year data retention without requiring high-voltage programming.
It features dual end-of-write detection: software polling of BUSY bit in status register (bit 0), and hardware RY/BY# output on SO pin during Auto Address Increment (AAI) mode-enabled via EBSY (70H) command. Memory organization includes uniform 4 KByte sectors, 32 KByte overlay blocks, and 64 KByte overlay blocks, all erasable independently.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Winbond W25Q16JVSSIQ | 16 Mbit, 104 MHz max clock, Quad SPI (QPI) mode supported; no HOLD# pin; different status register map | Lacks HOLD# and hardware RY/BY# on SO; requires QPI-aware controller; higher speed but less SPI-mode compatibility | Choose for bandwidth-constrained designs needing >50 MHz throughput and QPI support; verify HOLD#/WP# signal mapping in existing layout |
| Cypress S25FL116K0XMFI011 | 16 Mbit, 85 MHz max clock, supports SFDP; different erase granularity (4 KB sectors only); no AAI programming | No Auto Address Increment; relies on standard Byte-Program or Page-Program; lacks hardware busy indication on SO | Prefer when standardized SFDP discovery is required or when AAI complexity is unnecessary; confirm absence of AAI does not impact update latency budget |

All timing specifications assume proper signal integrity, VDD ≥ 2.7 V, and ambient temperature within –40°C to +85°C.
Does SST25VF016B-50-4C-QAF support both SPI Mode 0 and Mode 3?
Yes, SST25VF016B-50-4C-QAF is fully compatible with SPI Mode 0 (CPOL = 0, CPHA = 0) and Mode 3 (CPOL = 1, CPHA = 1). The device samples SI on the rising edge and drives SO on the falling edge of SCK in both modes, enabling interoperability with diverse host controllers without protocol translation.
How does hardware end-of-write detection work on SST25VF016B-50-4C-QAF?
SST25VF016B-50-4C-QAF supports hardware RY/BY# output on the SO pin during AAI programming. After issuing EBSY (70H), SO reflects internal busy status: low = busy, high = ready. This eliminates software polling overhead and allows interrupt-driven completion handling-critical for real-time deterministic response in SST25VF016B-50-4C-QAF implementations.
What package options are available for SST25VF016B-50-4C-QAF?
The SST25VF016B-50-4C-QAF is offered in two RoHS-compliant packages: 8-lead SOIC (200 mil) and 8-contact WSON (6 mm × 5 mm). The QAF suffix explicitly denotes the 8-lead SOIC variant. Pin assignments, thermal characteristics, and solder reflow profiles differ between packages and must be selected per board layout and thermal requirements.
Can SST25VF016B-50-4C-QAF be used in automotive applications?
The SST25VF016B-50-4C-QAF is qualified for industrial temperature range (–40°C to +85°C) and meets AEC-Q100 stress test requirements per Microchip documentation. While not officially AEC-Q100 certified, its performance envelope and reliability metrics (100,000 cycles, >100-year retention) support Tier-2 automotive subsystems such as infotainment and body control modules where full qualification is not mandated.
