Product details
Overview
SST26VF016-80-5C-QAE from Microchip Technology is a 16 Mbit Serial Quad I/O™ (SQI™) flash memory IC designed for high-speed, low-pin-count embedded code storage and data logging. It operates at 2.7–3.6 V, supports 80 MHz clock frequency, delivers 320 Mbit/s sustained read throughput via 4-bit multiplexed I/O, and features 100,000 program/erase cycles with >100-year data retention. It is used in GPS modules, Bluetooth headsets, and optical disk drives requiring XIP-capable nonvolatile memory.
For engineers reviewing the SST26VF016-80-5C-QAE datasheet, SST26VF016-80-5C-QAE pinout, SST26VF016-80-5C-QAE application, or SST26VF016-80-5C-QAE equivalent, key selection considerations include SQI vs. SPI mode compatibility, 8-contact WSON (6 mm × 5 mm) package constraints, 4 KByte uniform sector erase granularity, security ID programmability, and industrial temperature range (-40°C to +85°C) compliance.
Technical Context
The SST26VF016-80-5C-QAE implements a 4-bit multiplexed serial interface (SIO[3:0]) supporting both legacy SPI (Mode 0/3, SI/SO) and high-performance SQI protocols, enabling quad-data-rate transfers without additional pins. Its SuperFlash® split-gate CMOS technology enables single-supply 2.7–3.6 V operation, fast 1 ms page-program time, and 18 ms block-erase time.
It integrates a 48-bit Block-Protection Register with per-block write-lock and parameter-block read-lock capability, plus a 256-bit Security ID (64-bit factory-unique + 192-bit user-programmable). The device supports index-jump addressing, burst wrap modes (8/16/32/64 Byte), and write-suspend/resume functionality across sectors and blocks.

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 W25Q16JVSIQ | 16 Mbit, 133 MHz QSPI, 4-byte address mode optional, no Index Jump or Security ID | Lacks hardware-based read-lock and relative addressing; requires external ECC for extended reliability | Preferred where maximum clock speed and QPI dual/quad mode are prioritized over security and low-latency jump operations |
| Cypress S25FL116K0XMFI011 | 16 Mbit, 104 MHz, HyperBus interface option, no SQI protocol, different status register layout | Requires HyperFlash-compatible controller; lacks SuperFlash endurance and 100-year retention guarantee | Selected when migrating from legacy HyperBus platforms or needing pin-compatible drop-in for Cypress-design ecosystems |
Compared with SST26VF016-80-5C-QAE, W25Q16JVSIQ offers higher clock speed but omits security ID and index-jump addressing, while S25FL116K0XMFI011 provides HyperBus compatibility at the expense of SQI-specific optimizations and lower endurance specification.

FAQ
What interface protocols does the SST26VF016-80-5C-QAE support?
The SST26VF016-80-5C-QAE supports both Serial Peripheral Interface (SPI) Mode 0 and Mode 3 for backward compatibility, and its native Serial Quad I/O™ (SQI™) protocol using SIO[3:0] for 4-bit multiplexed transfers. After power-on reset, it defaults to SPI mode; the EQIO command (0x38) enables SQI mode. The SST26VF016-80-5C-QAE achieves 80 MHz operation only in SQI mode, delivering up to 320 Mbit/s sustained read throughput.
Does the SST26VF016-80-5C-QAE support execute-in-place (XIP) operation?
Yes, the SST26VF016-80-5C-QAE supports true execute-in-place (XIP) operation due to its low-latency, high-speed 80 MHz SQI interface and uniform memory architecture. This allows a host processor to fetch instructions directly from flash without copying to RAM, reducing boot time and SRAM usage. The SST26VF016-80-5C-QAE's continuous burst read and index-jump addressing further optimize XIP performance in real-time embedded applications.
What is the memory organization of the SST26VF016-80-5C-QAE?
The SST26VF016-80-5C-QAE contains 16 Mbit (2 MByte) of flash memory organized into thirty 64 KByte uniform overlay blocks, eight 8 KByte parameter blocks, and two 32 KByte overlay blocks. It also supports uniform 4 KByte erasable sectors. This hierarchical structure enables flexible firmware partitioning - for example, dedicating top/bottom parameter blocks for calibration data and 64 KByte blocks for application images. The SST26VF016-80-5C-QAE's memory map is fixed and documented in Figure 3 of DS-25017A.
How does the Security ID feature work on the SST26VF016-80-5C-QAE?
The SST26VF016-80-5C-QAE includes a 256-bit Security ID (Sec ID) with a factory-programmed 64-bit unique identifier and a user-programmable 192-bit segment. The Sec ID is programmed via the Program SID command (0xA5) and locked permanently using the Lockout SID command (0x85), after which the SEC bit in the status register reads '1'. Once locked, neither segment can be altered. The SST26VF016-80-5C-QAE's Security ID supports device authentication, license binding, and secure boot verification in regulated systems.
What package type is used for the SST26VF016-80-5C-QAE?
The SST26VF016-80-5C-QAE is packaged in an 8-contact WSON (6 mm × 5 mm) body with exposed pad, compliant with JEDEC MO-229 and RoHS standards. This compact, surface-mount package offers thermal and electrical performance advantages over SOIC variants and is optimized for high-density PCB layouts. The pinout matches the 8-lead SOIC variant electrically but differs mechanically - the SST26VF016-80-5C-QAE's WSON footprint requires specific reflow profile and solder paste stencil design per Microchip's AN1203 guidelines.
