Product details

Overview

SST25VF016B-75-4I-QAF-T from Microchip Technology is a 16 Mbit SPI serial flash memory IC with 2.7–3.6 V single-supply operation, 80 MHz max clock frequency, and SuperFlash® technology enabling 100,000 program/erase cycles and >100-year data retention. It serves as nonvolatile code/data storage in microcontroller boot loaders, firmware update buffers, and embedded configuration memory.

For engineers reviewing the SST25VF016B-75-4I-QAF-T datasheet, SST25VF016B-75-4I-QAF-T pinout, SST25VF016B-75-4I-QAF-T application, or SST25VF016B-75-4I-QAF-T equivalent, this page delivers verified electrical specs, SOIC-8 and WSON-8 package mapping, SPI Mode 0/3 compatibility, AAI programming support, and industrial-grade (-40°C to +85°C) operation for reliable embedded system integration.

Technical Context

The SST25VF016B-75-4I-QAF-T implements a four-wire SPI interface (SCK, SI, SO, CE#) with dual-mode clocking (SPI Mode 0 and Mode 3), supporting high-speed read at up to 80 MHz via the 0BH command with dummy cycle. Its internal SuperFlash® split-gate cell architecture enables fast erase-35 ms chip-erase, 18 ms sector/block-erase-and 7 µs byte-program time.

It integrates hardware and software write protection: HOLD# suspends ongoing SPI sequences without deselecting the device, WP# enables lock-down of block-protection bits (BP3–BP0, BPL), and the status register provides real-time BUSY/WEL/AAI state feedback. Auto Address Increment (AAI) mode allows sequential word programming without reissuing addresses, reducing firmware update latency.

Key Specifications

Pinout & Package

Package: 8-lead SOIC (200 mil), RoHS-compliant, surface-mountable with standard reflow profile.

Pin/Terminal	Circuit Role	Design Meaning
CE#	Chip Enable	Active-low device select; must remain low throughout command execution to prevent premature termination.
SO	Serial Data Output	Tri-state output; drives data on falling SCK edge; reconfigurable as RY/BY# during AAI programming for hardware busy detection.
WP#	Write Protect	Enables/disables lock-down of Block-Protection bits (BP3–BP0, BPL); low = BPL active, preventing further BP bit changes.
VSS	Ground	Reference return path for all I/O and core logic; requires low-impedance PCB connection to minimize noise coupling.
VDD	Power Supply	2.7–3.6 V supply input; decoupling capacitor (0.1 µF ceramic) required within 5 mm of pin for stable read/write margins.
HOLD#	Hold Control	Pauses SPI communication mid-sequence without resetting internal state; used for priority interrupt handling in real-time systems.
SCK	Serial Clock	Timing reference for SI/SO; rising edge latches input, falling edge outputs data; supports 0–80 MHz range with setup/hold compliance.
SI	Serial Data Input	Command/address/data input; MSB-first; sampled on rising SCK edge; tolerant of VIH/VIL levels per SPI spec.

Key Features

Feature	Design Value
SuperFlash® Technology	Split-gate cell + thick-oxide tunneling injector enables lower program current and shorter erase time vs. conventional flash, reducing total energy per operation.
Auto Address Increment (AAI)	Eliminates address retransmission overhead during multi-byte programming; cuts firmware update time by ~40% compared to byte-program mode.
Dual SPI Mode Support	Native compatibility with both Mode 0 (SCK idle low) and Mode 3 (SCK idle high), simplifying integration with legacy and new MCU platforms.
Flexible Erase Granularity	Uniform 4 KB sectors, 32 KB blocks, and 64 KB blocks allow precise firmware partitioning-e.g., separate bootloader, app, and config sections.
Hardware Busy Detection	SO pin repurposed as RY/BY# during AAI mode (via EBSY command), enabling interrupt-driven polling instead of software status register reads.

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 (x4 I/O), no HOLD# pin; 100k endurance, same voltage/temp range.	Lacks HOLD# and native dual SPI mode; requires Quad SPI host for full speed; better suited for bandwidth-constrained designs needing faster reads.	Select W25Q16JV-IQ only if host supports Quad SPI and HOLD# functionality is unnecessary; verify pinout and command set compatibility before layout reuse.
Macronix MX25L1606E-M2I-12G	16 Mbit, 80 MHz max clock, SPI Mode 0/3, includes HOLD# and WP#; 100k endurance, same voltage/temp; no AAI mode.	Missing AAI programming; relies on standard byte-program or page-program; slightly higher typical active current (15 mA vs. 10 mA).	Choose MX25L1606E-M2I-12G when AAI is not required and cost sensitivity outweighs minor power/performance trade-offs; pinout matches SOIC-8 variant.

Compared with SST25VF016B-75-4I-QAF-T, W25Q16JV-IQ offers higher bandwidth via Quad SPI but removes HOLD# and dual-mode flexibility, while MX25L1606E-M2I-12G retains pin compatibility and industrial temp rating but omits AAI-making SST25VF016B-75-4I-QAF-T optimal for real-time systems requiring deterministic suspend/resume and accelerated firmware writes.

FAQ

What is the maximum clock frequency supported by the SST25VF016B-75-4I-QAF-T?

The SST25VF016B-75-4I-QAF-T supports up to 80 MHz for high-speed read operations using the 0BH instruction with dummy cycle, and up to 25 MHz for standard read (03H). All write/erase commands also operate at 80 MHz, enabling fast firmware updates and configuration writes in time-critical embedded systems.

Does the SST25VF016B-75-4I-QAF-T support both SPI Mode 0 and Mode 3?

Yes, the SST25VF016B-75-4I-QAF-T explicitly supports both SPI Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1), as confirmed in the DS25044A datasheet. This dual-mode compatibility allows seamless integration with a wide range of microcontrollers-including legacy and newer silicon-without requiring hardware or firmware adaptation.

What is the purpose of the HOLD# pin on the SST25VF016B-75-4I-QAF-T?

The HOLD# pin on the SST25VF016B-75-4I-QAF-T temporarily 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 and pauses clock synchronization-enabling priority interrupt handling in real-time systems while preserving command context for resumption.

How does Auto Address Increment (AAI) programming improve efficiency in the SST25VF016B-75-4I-QAF-T?

AAI programming in the SST25VF016B-75-4I-QAF-T eliminates the need to retransmit the address for each subsequent word, reducing SPI bus traffic and total programming time. After issuing ADH + address + two data bytes, the next ADH command automatically advances to the next word address-cutting firmware update latency by ~40% versus standard byte-program mode.

What write protection mechanisms does the SST25VF016B-75-4I-QAF-T provide?

The SST25VF016B-75-4I-QAF-T provides three-tiered write protection: hardware via WP# (enabling BPL lock-down of BP bits), hardware via HOLD# (pausing writes), and software via BP3–BP0 bits in the status register-configurable to protect sectors, blocks, or the entire array. All mechanisms coexist and are validated for industrial use cases requiring tamper-resistant configuration storage.
