Product details
Overview
SST26VF016BT-104I/MF70SVAO from Microchip Technology is a 16 Mbit Serial Quad I/O™ (SQI™) flash memory IC operating at up to 104 MHz (2.7–3.6V), supporting x1/x2/x4 SPI and full SQI protocols, with uniform 4 KByte sectors, 100,000 program/erase cycles, and industrial temperature range (–40°C to +85°C). It serves as nonvolatile code/data storage in microcontroller boot loaders and firmware update systems.
For engineers reviewing the SST26VF016BT-104I/MF70SVAO datasheet, SST26VF016BT-104I/MF70SVAO pinout, SST26VF016BT-104I/MF70SVAO application, or SST26VF016BT-104I/MF70SVAO equivalent, key selection considerations include SQI vs. SPI mode configuration, hardware write-protection pin behavior (WP#), burst read capability, sector protection granularity, and deep power-down current (15 µA typical).
Technical Context
The SST26VF016BT-104I/MF70SVAO implements a six-wire, 4-bit multiplexed I/O interface (SIO[3:0]) compatible with both traditional SPI (Mode 0/3) and high-speed SQI protocols - enabling quadrupled data throughput at identical clock frequencies. Its SuperFlash® split-gate cell architecture delivers faster erase (sector: 18 ms typ) and lower total energy per operation versus conventional flash.
It features dual protection layers: volatile Block-Protection Register (BPR) with individual 8/32/64 KByte block lock control, and non-volatile Write-Lock Lock-Down register (nVWLDR) that permanently disables further changes to selected BPR bits. The Security ID includes 64-bit factory-unique OTP and 2 KByte user-programmable area.

Applications
| Boot Code Storage | Firmware Over-the-Air (OTA) Updates |
|---|---|
Use Scenario: Storing primary bootloader and initial firmware image for ARM Cortex-M or RISC-V microcontrollers during cold start. IC Role / Device Role / Timing Role: Nonvolatile code execution source; accessed via XIP-capable SPI/SQI controller with linear burst reads for fast instruction fetch. Use Value: 104 MHz SQI interface reduces boot time by ~3× vs. legacy SPI flash; 4 KByte sector granularity enables atomic bootloader updates without risking corruption. |
Use Scenario: Hosting delta patches and full firmware images downloaded wirelessly to IoT edge nodes with constrained memory. IC Role / Device Role / Timing Role: Field-updatable storage partition; leverages Write-Suspend to allow real-time sensor reads during background flash programming. Use Value: 18 ms sector erase and 256-byte page programming enable sub-second patch application; deep power-down (1 µA) extends battery life between updates. |
| Secure Device Identity | Industrial HMI Configuration Storage |
Use Scenario: Providing cryptographically verifiable device identity in automotive telematics or medical diagnostics equipment. IC Role / Device Role / Timing Role: Tamper-resistant identity anchor; Security ID locked via LSID after provisioning, preventing unauthorized reprogramming. Use Value: Factory-unique 64-bit OTP ID ensures unclonable device binding; user-programmable 2 KByte area stores cryptographic keys or calibration certificates. |
Use Scenario: Retaining display layouts, language packs, and calibration offsets across power cycles in factory HMIs and PLC operator panels. IC Role / Device Role / Timing Role: Parameter storage with robust write endurance; individual 8 KByte parameter block protection prevents accidental overwrite of critical settings. Use Value: 100,000-cycle endurance exceeds 10-year industrial deployment requirements; hardware WP# pin + BPR lock-down ensures settings survive ESD events and brownouts. |
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 W25Q16JVSNIQ | 16 Mbit SPI-only (no SQI); 133 MHz max; 100K cycles; same SOIC-8 package but different pinout (no SIO[2:3] multiplexing) | Lacks SQI bandwidth boost and write-suspend; requires separate HOLD#/WP# pins instead of multiplexed SIO | Select when SQI is unnecessary and legacy SPI compatibility is prioritized over speed and advanced protection features |
| Cypress S25FL116K0XMFI011 | 16 Mbit dual/quad SPI; 85 MHz max; 100K cycles; supports octal DTR mode; different status register layout and protection scheme | No non-volatile lock-down register; uses different command set (e.g., no EQIO/LSID); lacks Security ID OTP segment | Select when migrating from Cypress portfolio or requiring octal DTR for future scalability; verify protection and security flow alignment |
Compared with Winbond W25Q16JVSNIQ and Cypress S25FL116K0XMFI011, the SST26VF016BT-104I/MF70SVAO uniquely combines SQI bandwidth, two-tier write protection (volatile + non-volatile), and factory-unique Security ID - making it optimal for secure, high-throughput embedded boot and update architectures where pin count and firmware integrity are critical.

FAQ
What is the maximum clock frequency supported by SST26VF016BT-104I/MF70SVAO?
The SST26VF016BT-104I/MF70SVAO supports up to 104 MHz when operated at 2.7–3.6V supply voltage, and up to 80 MHz at 2.3–3.6V or under extended temperature conditions (–40°C to +125°C). This is confirmed in the "Features" section of DS20005262F, where "High Speed Clock Frequency" specifies these exact values per voltage range.
Does SST26VF016BT-104I/MF70SVAO support both SPI and SQI protocols?
Yes, the SST26VF016BT-104I/MF70SVAO supports both traditional SPI (x1/x2/x4 modes, Mode 0/3) and Serial Quad I/O™ (SQI) protocol. After power-on reset, it defaults to SPI mode; the EQIO command (38H) and IOC bit configuration enable SQI mode, using SIO[3:0] for 4-bit multiplexed I/O as documented in Section 4.0 and Table 5-1.
How is hardware write protection implemented on SST26VF016BT-104I/MF70SVAO?
Hardware write protection on the SST26VF016BT-104I/MF70SVAO uses the WP# pin (SIO2) in conjunction with the WPEN bit (non-volatile, default '0') and IOC bit (default '0') in the Configuration register. When WPEN = 1 and IOC = 0, pulling WP# low disables writes to the Block-Protection and Configuration registers - as defined in Table 4-1 and Section 4.2 of DS20005262F.
What is the purpose of the Security ID feature in SST26VF016BT-104I/MF70SVAO?
The Security ID in SST26VF016BT-104I/MF70SVAO provides a 2 KByte dedicated space comprising a factory-programmed 64-bit unique identifier and a user-programmable area. It supports device authentication and secure provisioning; once locked via the LSID command, no further writes are permitted - as specified in Section 4.3 and Table 5-1 of the official datasheet.
Can SST26VF016BT-104I/MF70SVAO suspend an ongoing erase or program operation?
Yes, the SST26VF016BT-104I/MF70SVAO supports Write-Suspend: issuing the WRSU command (B0H) pauses active Program or Erase operations, allowing immediate access to other memory regions. Status bits WSP and WSE in the Status register indicate suspension state, and WRRE (30H) resumes the suspended operation - per Sections 4.5.2–4.5.3 and Table 5-1.
