Product details
Overview
SST26VF016-80-5I-S2AE-T 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 with 320 Mbit/s sustained read throughput, features uniform 4 KByte sectors and 64 KByte overlay blocks, and is qualified for industrial temperature range (−40°C to +85°C). It serves as XIP-capable boot memory in portable electronics such as GPS modules and Bluetooth headsets.
For engineers reviewing the SST26VF016-80-5I-S2AE-T datasheet, SST26VF016-80-5I-S2AE-T pinout, SST26VF016-80-5I-S2AE-T application, or SST26VF016-80-5I-S2AE-T equivalent, key selection considerations include its SQI/quad-I/O interface compatibility, 256-byte page programming capability, software write-protection granularity, and dual-package availability (SOIC-8 and WSON-8).
Technical Context
The SST26VF016-80-5I-S2AE-T implements a 4-bit multiplexed serial interface supporting both legacy SPI (Mode 0/3) and proprietary SQI protocol, enabling quad-data-rate transfers without increasing pin count. Its SuperFlash® technology uses split-gate cells and thick-oxide tunneling to deliver 100,000 program/erase cycles and >100 years data retention.
It integrates a programmable Block-Protection Register (48-bit for SST26VF016), OTP Security ID (64-bit factory + 192-bit user), and full command-set support including Write-Suspend, Index Jump, and burst modes (8/16/32/64-byte wrap-around), all accessible via CE#/SCK/SIO[3:0] control.

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 interface (no SQI); 133 MHz max clock; Quad Enable bit required to activate QPI mode | Lacks native SQI protocol and Index Jump commands; requires additional software abstraction for burst optimization | Choose when legacy SPI compatibility is prioritized over bandwidth density and advanced command efficiency |
| Cypress S25FL116K0XMFI011 | 16 Mbit HyperFlash-compatible interface; 104 MHz DDR clock; different command set and status register layout | Designed for high-speed execute-in-place in microcontroller-based systems; not pin-compatible with SST26VF016 | Prefer for ARM Cortex-M7/M33 platforms with HyperBus controllers requiring higher throughput than SQI offers |
Compared with SST26VF016-80-5I-S2AE-T, W25Q16JVSIQ provides broader SPI ecosystem support but lacks SQI's bandwidth efficiency and Index Jump flexibility, while S25FL116K0XMFI011 targets higher-performance XIP use cases with incompatible interface signaling and no direct pin or command mapping.

FAQ
What interface protocols does the SST26VF016-80-5I-S2AE-T support?
The SST26VF016-80-5I-S2AE-T supports both Serial Peripheral Interface (SPI) Mode 0 and Mode 3 for backward compatibility, and its native Serial Quad I/O™ (SQI™) protocol using multiplexed SIO[3:0]. After power-on reset, it defaults to SPI mode; the EQIO command (0x38) enables SQI operation. The SST26VF016-80-5I-S2AE-T achieves 320 Mbit/s sustained read throughput in SQI mode at 80 MHz, significantly exceeding standard SPI limits.
Does the SST26VF016-80-5I-S2AE-T support execute-in-place (XIP) operation?
Yes, the SST26VF016-80-5I-S2AE-T enables minimum-latency execute-in-place (XIP) capability due to its 80 MHz clock frequency and SQI interface, eliminating the need to shadow code into external SRAM. Its fast High-Speed Read (0xBH) command delivers deterministic access timing, making the SST26VF016-80-5I-S2AE-T suitable for real-time boot loaders and firmware execution directly from flash in portable electronics.
What is the memory organization of the SST26VF016-80-5I-S2AE-T?
The SST26VF016-80-5I-S2AE-T contains 16 Mbit (2 MByte) of flash memory organized into thirty 64 KByte uniform overlay blocks, eight 8 KByte parameter blocks (four top, four bottom), and two 32 KByte overlay blocks (one top, one bottom). All erasable units-including 4 KByte sectors-are supported. This structure allows flexible firmware partitioning, secure parameter storage, and field-upgrade-safe erase granularity.
How does the Write-Suspend feature work in the SST26VF016-80-5I-S2AE-T?
The SST26VF016-80-5I-S2AE-T supports Write-Suspend to pause an ongoing Program or Erase operation, allowing immediate access to another memory block or sector for time-critical reads. Issuing the B0H command suspends the operation, setting the WSP or WSE bit in the Status Register. The SST26VF016-80-5I-S2AE-T resumes via the 30H command. This is essential for real-time systems where background flash maintenance must not block foreground data access.
Is the SST26VF016-80-5I-S2AE-T available in multiple package options?
Yes, the SST26VF016-80-5I-S2AE-T is offered in two RoHS-compliant packages: 8-lead SOIC (200 mil) and 8-contact WSON (6 mm × 5 mm). Both share identical pinout and electrical specifications. The WSON variant is optimized for space-constrained portable designs like Bluetooth headsets and GPS modules, while the SOIC version facilitates prototyping and through-hole assembly in industrial control boards.
