Product details
Overview
SST26VF016-80-5I-QAE-T from Microchip Technology is a 16 Mbit Serial Quad I/O™ (SQI™) flash memory IC designed for high-speed, low-pin-count code storage in embedded systems. It operates at 2.7–3.6 V, supports 80 MHz clock frequency, delivers 320 Mbit/s sustained data rate in SQI mode, and features uniform 4 KByte sectors with 30 erasable blocks - used in boot code storage for portable GPS and Bluetooth headsets.
For engineers reviewing the SST26VF016-80-5I-QAE-T datasheet, SST26VF016-80-5I-QAE-T pinout, SST26VF016-80-5I-QAE-T application, or SST26VF016-80-5I-QAE-T equivalent, key selection criteria include SQI vs. SPI protocol compatibility, industrial temperature range (-40°C to +85°C), WSON-8 package footprint, 100,000 write/erase endurance, and security ID programmability.
Technical Context
The SST26VF016-80-5I-QAE-T implements a 4-bit multiplexed I/O serial interface using SIO[3:0] pins, supporting both Mode 0 and Mode 3 SPI-compatible timing while enabling quad-data-rate transfers. Its SuperFlash® technology uses split-gate cells and thick-oxide tunneling for enhanced reliability and lower energy per program/erase cycle.
It integrates a 256-byte page buffer, supports execute-in-place (XIP) with minimal latency, and provides flexible erase granularity: 4 KByte sectors, eight 8 KByte parameter blocks, two 32 KByte overlay blocks, and thirty 64 KByte overlay blocks - all configurable via software block protection and lock-down registers.

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 SPI-only (no native SQI); 133 MHz max clock; Quad Enable bit required to activate QPI mode | Lacks native SQI protocol - requires additional initialization and lacks Index Jump or Write-Suspend features | Choose when legacy SPI design reuse is prioritized over throughput and advanced command flexibility |
| Cypress S25FL116K0XMFI011 | 16 Mbit, 85 MHz, supports both SPI and QSPI; includes sector protection but no Security ID or Index Jump | No OTP Security ID or relative-addressing commands - limits secure boot and dynamic firmware patching capability | Prefer when QSPI timing compliance and Cypress ecosystem tooling outweigh need for Microchip-specific security and efficiency features |
Compared with W25Q16JVSIQ and S25FL116K0XMFI011, the SST26VF016-80-5I-QAE-T uniquely combines native SQI throughput, Index Jump addressing, and factory-programmed Security ID - making it optimal for compact, secure, real-time firmware storage where command efficiency and authentication are critical.

FAQ
What interface protocols does the SST26VF016-80-5I-QAE-T support?
The SST26VF016-80-5I-QAE-T supports both standard SPI (Mode 0/3) and native Serial Quad I/O™ (SQI™) protocols. At power-on reset, it defaults to SPI mode for JEDEC ID, Read, and High-Speed Read. The EQIO command (0x38) enables SQI mode, activating all four SIO pins for quad-data-rate transfers. Unlike SPI-only alternatives, SST26VF016-80-5I-QAE-T requires no external quad-enable bit setting - SQI is a dedicated, optimized bus state.
Does the SST26VF016-80-5I-QAE-T support execute-in-place (XIP) operation?
Yes, the SST26VF016-80-5I-QAE-T supports true execute-in-place functionality due to its 80 MHz SQI interface and low-latency command structure. With 320 Mbit/s sustained read bandwidth and continuous linear burst modes, it enables direct CPU instruction fetch from flash without shadowing to SRAM - reducing system memory cost and boot time. This capability is validated in GPS and Bluetooth headset reference designs using the SST26VF016-80-5I-QAE-T.
What is the memory organization of the SST26VF016-80-5I-QAE-T?
The SST26VF016-80-5I-QAE-T organizes its 16 Mbit array into thirty 64 KByte erasable overlay blocks, eight 8 KByte parameter blocks, two 32 KByte overlay blocks, and uniform 4 KByte sectors. This hierarchical layout allows fine-grained firmware updates (sector-level), secure parameter storage (8 KByte blocks), and large-image storage (64 KByte blocks). The SST26VF016-80-5I-QAE-T datasheet confirms exactly 30 blocks for this density, distinct from the 62-block SST26VF032 variant.
How does the Security ID feature work on the SST26VF016-80-5I-QAE-T?
The SST26VF016-80-5I-QAE-T includes a 256-bit Security ID: 64 bits factory-programmed with a unique identifier (read-only), and 192 bits user-programmable. Programming uses the Program SID command (0xA5), and locking uses Lockout SID (0x85), which sets the SEC bit permanently. Once locked, no further writes to the Security ID are possible - ensuring immutable device identity for secure boot and anti-cloning. This feature is exclusive to the SST26VF016-80-5I-QAE-T within its family and not emulated by pin-compatible alternatives.
What package type is used for the SST26VF016-80-5I-QAE-T?
The SST26VF016-80-5I-QAE-T uses an 8-contact WSON (6 mm × 5 mm) package, specified in the official Microchip datasheet DS-25017A. This leadless, surface-mount package offers superior thermal performance and board-area efficiency versus SOIC-8, with exposed pad for enhanced heat dissipation. Pin assignments match Figure 2 in the datasheet, and the "QAE" suffix explicitly denotes the WSON-8 variant - confirmed by Microchip's packaging nomenclature and distributor listings.
