Product details
Overview
SST26VF016BT-104I/MF from Microchip Technology is a 16 Mbit Serial Quad I/O (SQI) flash memory IC operating at up to 104 MHz (2.7–3.6 V), featuring uniform 4 KByte sectors, 256-byte page programming, and AEC-Q100 qualification for automotive use. It supports SPI x1/x2/x4 and SQI protocols in an 8-contact WDFN (6 mm × 5 mm) package and is deployed in engine control units, ADAS boot storage, and infotainment firmware retention.
For engineers reviewing the SST26VF016BT-104I/MF datasheet, SST26VF016BT-104I/MF pinout, SST26VF016BT-104I/MF application, or SST26VF016BT-104I/MF equivalent, key selection considerations include quad-I/O burst timing, industrial-plus temperature range (−40°C to +105°C), write-suspend capability, hardware write protection via WP# pin, and OTP Security ID with factory-programmed 64-bit identifier.
Technical Context
The SST26VF016BT-104I/MF implements a six-wire SQI interface (SCK, CE#, VDD, VSS, SIO[3:0]) with configurable I/O modes (SPI Mode 0/3, x1/x2/x4, and quad I/O), enabling up to 4× bandwidth over standard SPI at identical clock frequency. Its SuperFlash® split-gate cell architecture delivers 100,000 program/erase cycles and >100-year data retention.
It integrates dual protection layers: volatile Block-Protection Register (BPR) with per-block write/read lock control, and non-volatile Write-Lock Lock-Down Register (nVWLDR) that permanently fixes protection bits. The device defaults to SPI mode at power-up and requires explicit EQIO command to enable SQI operation.

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 W25Q16JVSIM | 16 Mbit SPI-only (no SQI), 133 MHz max, 8-lead SOIC package only, no OTP Security ID | Lacks quad I/O bandwidth and automotive qualification; suitable for cost-sensitive consumer electronics | Select when SQI performance and AEC-Q100 compliance are not required; verify SOIC footprint compatibility |
| Cypress S25FL116K0XMFI001 | 16 Mbit, 85 MHz max, supports XIP but no write-suspend or nVWLDR; -40°C to +85°C industrial grade only | Missing Industrial Plus temperature range and permanent block lock-down - limits use in under-hood environments | Choose only for non-automotive industrial designs where XIP execution is prioritized over protection granularity |
Compared with W25Q16JVSIM and S25FL116K0XMFI001, the SST26VF016BT-104I/MF uniquely combines AEC-Q100 qualification, SQI bandwidth, write-suspend, and OTP Security ID - making it the sole option for automotive boot storage demanding both speed and security at extended temperature.

FAQ
What is the maximum operating frequency of the SST26VF016BT-104I/MF and under what voltage conditions?
The SST26VF016BT-104I/MF achieves a maximum clock frequency of 104 MHz when operated within the 2.7–3.6 V supply range. At the wider 2.3–3.6 V range, its maximum frequency is 80 MHz. This specification is confirmed in the official Microchip datasheet DS20005262F, Section 1.0 Features, and applies to both SPI and SQI read operations. The SST26VF016BT-104I/MF maintains this performance across its full −40°C to +105°C industrial-plus temperature range.
Does the SST26VF016BT-104I/MF support true quad I/O mode, and how is it enabled?
Yes, the SST26VF016BT-104I/MF supports true quad I/O (SQI) mode using all four SIO[3:0] pins for simultaneous bidirectional data transfer. It is enabled by first setting the IOC bit (Bit 1) in the Configuration Register to '1', then issuing the Enable Quad I/O (EQIO, 0x38) command. The device powers up in SPI mode by default; SQI mode is not active until both steps are completed. This behavior is documented in DS20005262F, Sections 4.1 and 5.0.
What protection mechanisms does the SST26VF016BT-104I/MF provide against unauthorized writes?
The SST26VF016BT-104I/MF implements three layered protections: (1) software-controlled Block-Protection Register (BPR) with per-block write/read lock bits; (2) volatile Lock-Down Block-Protection Register (LBPR) command that disables further BPR changes until power cycle; and (3) non-volatile nVWLDR that permanently fixes write-lock bits. Additionally, the hardware WP# pin can disable writes to protection registers when configured. All are detailed in DS20005262F, Section 4.1.
Is the SST26VF016BT-104I/MF qualified for automotive applications, and what certification does it hold?
Yes, the SST26VF016BT-104I/MF is explicitly AEC-Q100 qualified for automotive applications, as stated in the "Features" section of DS20005262F. It meets Grade 2 (−40°C to +105°C) requirements and is rated for under-hood and safety-critical ECU use. This qualification is distinct from industrial-grade alternatives and confirms reliability under automotive thermal, vibration, and ESD stress conditions.
What is the purpose and structure of the Security ID feature in the SST26VF016BT-104I/MF?
The SST26VF016BT-104I/MF includes a 2 KByte Security ID (Sec ID) area comprising a factory-programmed 64-bit unique identifier (immutable) and a user-programmable segment. The Sec ID supports secure boot authentication and device binding. It is programmed via PSID command and locked permanently via LSID command - once locked, no further writes are possible. This functionality is defined in DS20005262F, Section 4.3.
