Product details
Overview
SST26VF016BT-104V/MF from Microchip Technology is a 16 Mbit Serial Quad I/O (SQI) flash memory IC supporting dual-voltage operation (2.3–3.6 V), 104 MHz SPI read speed, 4 KByte uniform sector erase, and hardware/software write protection. It serves as nonvolatile code/data storage in microcontroller boot loaders and firmware update modules.
For engineers reviewing the SST26VF016BT-104V/MF datasheet, SST26VF016BT-104V/MF pinout, SST26VF016BT-104V/MF application, or SST26VF016BT-104V/MF equivalent, key selection criteria include SQI vs. SPI mode compatibility, 8-lead SOIC (3.90 mm) package footprint, industrial temperature range (–40°C to +85°C), and OTP Security ID integration for device authentication.
Technical Context
The SST26VF016BT-104V/MF implements a six-wire, 4-bit multiplexed I/O interface (SIO[3:0]) with full backward compatibility to standard SPI (Mode 0/3, x1/x2/x4). Its SuperFlash® split-gate cell technology enables 100,000 program/erase cycles and >100 years data retention.
It supports flexible protection via a 48-bit Block-Protection Register, volatile lock-down (LBPR), and non-volatile write-lock lock-down (nVWLDR), plus a 2 KByte Security ID with factory-programmed 64-bit unique identifier and user-programmable area.

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, 4 KByte sectors, no Security ID | Lacks SQI interface and OTP security features; suitable where quad I/O bandwidth not required | Select when cost-sensitive designs prioritize SPI compatibility over SQI performance and security |
| Cypress S25FL116K0XMFI00 | 16 Mbit SPI flash, 85 MHz max, 4 KByte sectors, no SQI or Security ID, supports XIP | Offers execute-in-place capability but omits SQI interface, burst wrap, and security extensions | Choose for legacy SPI systems needing XIP support and proven qualification in automotive AEC-Q100 Grade 2 |
Compared with W25Q16JVSIM and S25FL116K0XMFI00, the SST26VF016BT-104V/MF delivers higher effective bandwidth via SQI, integrated Security ID for device identity, and finer-grained parameter block protection - making it optimal for secure, upgradable embedded systems requiring compact footprint and industrial temperature operation.

FAQ
What voltage range does the SST26VF016BT-104V/MF support?
The SST26VF016BT-104V/MF operates from a single supply of 2.3 V to 3.6 V. This dual-range support enables compatibility with both 2.5 V and 3.3 V system rails. At 2.7–3.6 V, it achieves its rated 104 MHz maximum clock frequency; at 2.3–3.6 V, the max frequency is 80 MHz. The device maintains full functionality-including SQI mode, write-suspend, and Security ID-across the entire voltage range.
Does the SST26VF016BT-104V/MF support Quad I/O mode out of reset?
No. The SST26VF016BT-104V/MF powers up in standard SPI mode (x1) with SI/SO pins active. To enable Quad I/O mode, the host must first set the IOC bit in the Configuration register (via WRCR), then issue the EQIO (38H) command. Only after this sequence do SIO[3:0] become active as bidirectional quad lines. Failure to configure IOC before EQIO results in undefined behavior.
How is hardware write protection implemented on the SST26VF016BT-104V/MF?
Hardware write protection on the SST26VF016BT-104V/MF uses the WP# pin in conjunction with the WPEN and IOC bits in the Configuration register. WP# is active-low and only functional in SPI single/dual-bit modes when IOC = 0 and WPEN = 1. When asserted, it prevents writes to the Block-Protection and Configuration registers-but not to the main memory array. The default power-up state has WPEN = 0, disabling WP# until explicitly enabled.
What is the purpose of the Security ID feature in the SST26VF016BT-104V/MF?
The SST26VF016BT-104V/MF includes a 2 KByte Security ID (Sec ID) space comprising a factory-programmed 64-bit unique identifier and a user-programmable area. This feature enables device-level authentication and firmware binding. Once locked via the LSID command, the entire Sec ID space becomes read-only. The factory ID cannot be altered or erased, providing a tamper-resistant root of trust for secure boot and anti-counterfeiting applications.
Can the SST26VF016BT-104V/MF be used in automotive applications?
Yes. The SST26VF016BT-104V/MF is AEC-Q100 qualified for automotive applications. Its industrial temperature grade (–40°C to +85°C) and robust reliability metrics-including 100,000 program/erase cycles and >100 years data retention-meet stringent automotive requirements. It is commonly deployed in telematics control units, instrument clusters, and ADAS subsystems for boot code and configuration storage.
