Product details
Overview
SST26WF016BT-104I/MF from Microchip Technology is a 1.8V, 16 Mbit Serial Quad I/O (SQI) flash memory IC with 104 MHz max clock frequency, 4 KByte uniform sector erase, 256-byte page programming, and industrial temperature range (–40°C to +85°C). It serves as non-volatile program/data storage in microcontroller boot loaders, FPGA configuration, and embedded firmware updates.
For engineers reviewing the SST26WF016BT-104I/MF datasheet, SST26WF016BT-104I/MF pinout, SST26WF016BT-104I/MF application, or SST26WF016BT-104I/MF equivalent, key selection criteria include SQI/x4 SPI interface support, 1.65–1.95 V single-supply operation, 100,000 write/erase endurance, deep power-down current (2.5 μA), and hardware write protection via WP# pin.
Technical Context
The SST26WF016BT-104I/MF implements a six-wire, 4-bit multiplexed I/O interface (SIO[3:0]) supporting both Mode 0 and Mode 3 SPI timing, enabling up to 4× data throughput versus standard SPI at identical clock rates. Its SuperFlash® split-gate cell architecture delivers faster erase (sector: 18 ms typ) and lower total energy per operation than conventional NOR flash.
It integrates dual protection layers: volatile Block-Protection Register (BPR) with lock-down capability and non-volatile Write-Lock Lock-Down Register (nVWLDR), plus OTP 2 KByte Security ID with factory-programmed 64-bit unique identifier. The device defaults to SPI mode at power-up and requires explicit EQIO command to enable SQI mode.

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 W25Q16JWIM (16 Mbit, 1.6–1.95 V) | Same density, voltage, and SOIC/WSON packages; supports octal DTR but no native SQI; 133 MHz max clock | Lacks SQI protocol and integrated Security ID; uses different command set and protection model | Choose for octal interface compatibility or where Winbond's XIP+DTR performance is prioritized over Microchip's SQI simplicity and security features |
| Cypress S25FL116K0XMFI00 (16 Mbit, 2.7–3.6 V) | Higher VDD (2.7–3.6 V); no 1.8 V support; supports QPI and DDR modes; 85 MHz max clock | Not voltage-compatible with 1.8 V systems; lacks OTP Security ID and nVWLDR-level permanent lock | Choose only in legacy 3.3 V designs requiring Cypress toolchain alignment; not suitable as drop-in replacement due to voltage and feature mismatch |
Compared with W25Q16JWIM and S25FL116K0XMFI00, the SST26WF016BT-104I/MF uniquely combines 1.8 V operation, native SQI interface, and hardware-enforced permanent block lock-down-making it optimal for space-constrained, secure, low-power embedded boot and configuration use cases.

FAQ
What interface protocols does the SST26WF016BT-104I/MF support?
The SST26WF016BT-104I/MF supports both Serial Quad I/O (SQI) and backward-compatible SPI protocols-including x1, x2, and x4 modes-and operates in SPI Mode 0 and Mode 3. It defaults to SPI mode at power-up and requires the EQIO command to enable SQI functionality. The SST26WF016BT-104I/MF uses multiplexed SIO[3:0] pins in SQI mode and separate SI/SO in SPI mode, ensuring interoperability with legacy controllers while enabling 4× bandwidth scaling.
Does the SST26WF016BT-104I/MF support hardware write protection?
Yes, the SST26WF016BT-104I/MF supports hardware write protection via the WP# pin, which functions in SPI single-bit and dual-bit read modes when the IOC bit is '0' and WPEN bit is '1'. The WP# pin protects only the Block-Protection and Configuration registers-not the main memory array. The SST26WF016BT-104I/MF also provides software-based protection via the Block-Protection Register and non-volatile lock-down (nVWLDR), offering layered security against accidental or malicious writes.
What is the purpose of the Security ID feature in the SST26WF016BT-104I/MF?
The SST26WF016BT-104I/MF includes a 2 KByte Security ID (Sec ID) space comprising a factory-programmed 64-bit unique identifier and a user-programmable segment. This feature enables device authentication, secure boot verification, and anti-cloning measures. The SST26WF016BT-104I/MF allows locking the entire Sec ID space using the LSID command, after which no further writes are possible-ensuring immutable device identity critical for IoT and industrial edge deployments.
How does the SST26WF016BT-104I/MF handle power-down modes?
The SST26WF016BT-104I/MF offers three low-power states: standby (10 μA typical), deep power-down (2.5 μA typical), and automatic power-down after command completion. Deep power-down is entered via DPD command and exited with RDPD, which also reads JEDEC ID. The SST26WF016BT-104I/MF maintains full register state across deep power-down, and its 1.65–1.95 V operating range ensures compatibility with battery-backed and energy-harvesting systems requiring ultra-low quiescent current.
Can the SST26WF016BT-104I/MF be used in place of standard SPI flash devices?
Yes, the SST26WF016BT-104I/MF is fully command-set compatible with traditional SPI flash (e.g., "25" series), supporting standard instructions like Read (03H), Fast Read (0BH), Page Program (02H), and Sector Erase (20H). It operates in SPI mode by default at power-up and requires no hardware changes to replace legacy SPI flash-though full SQI performance benefits require firmware updates to issue EQIO and use SIO[3:0] quad commands. The SST26WF016BT-104I/MF retains pin compatibility with common 8-pin SOIC/WDFN footprints.
