Product details
Overview
SST26VF016BT-80E/MF from Microchip Technology is a 16 Mbit Serial Quad I/O (SQI) flash memory IC operating at 2.3–3.6 V, supporting 80 MHz max clock frequency, 4 KByte uniform sectors, and flexible block protection with OTP Security ID. It serves as non-volatile program/data storage in microcontroller boot loaders and firmware update systems.
For engineers reviewing the SST26VF016BT-80E/MF datasheet, SST26VF016BT-80E/MF pinout, SST26VF016BT-80E/MF application, or SST26VF016BT-80E/MF equivalent, key selection criteria include SQI vs. SPI mode compatibility, 80 MHz timing at 2.3–3.6 V, WDFN-8 (6×5 mm) package footprint, sector/block erase granularity, and hardware write-protection via WP# pin.
Technical Context
The SST26VF016BT-80E/MF implements a six-wire, 4-bit multiplexed I/O interface (SIO[3:0]) for SQI protocol operation, while maintaining full command-set compatibility with legacy SPI (Mode 0/3, x1/x2/x4). Its SuperFlash® split-gate cell architecture enables 100,000 program/erase cycles and >100 years data retention.
It supports dual operational modes: default SPI mode after power-on reset (SI/SO pins active), and configurable SQI mode (SIO[3:0] quad I/O) enabled via EQIO command. Write-suspend allows interleaved access to unprotected blocks during active erase/program operations, and the Status register provides real-time BUSY/WEL/WPLD monitoring.

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, 1.65–1.95 V / 2.7–3.6 V dual supply | Lacks SQI interface and write-suspend; supports lower voltage but no OTP Security ID | Select when SQI bandwidth is unnecessary and cost-sensitive SPI-only design suffices |
| Cypress S25FL116K0XMFI011 | 16 Mbit Quad SPI (QSPI), 104 MHz, 2.7–3.6 V, no OTP ID, different security register map | Supports QSPI commands but lacks nVWLDR and dedicated Security ID space | Choose for QSPI ecosystem alignment where Microchip-specific features are not required |
Compared with SST26VF016BT-80E/MF, W25Q16JVSNIQ offers higher SPI speed but no SQI or OTP ID; S25FL116K0XMFI011 delivers QSPI compatibility and similar timing but omits permanent block lock-down and factory-unique identification - making SST26VF016BT-80E/MF optimal for secure, high-throughput embedded boot and update architectures.

FAQ
What is the maximum clock frequency supported by SST26VF016BT-80E/MF?
The SST26VF016BT-80E/MF supports up to 80 MHz maximum clock frequency when operating within the 2.3–3.6 V supply range. This applies to both SPI and SQI protocols. At 2.7–3.6 V, it can reach 104 MHz, but the "-80E" suffix explicitly denotes the 80 MHz grade. The actual achievable frequency depends on signal integrity, PCB layout, and temperature - the 80 MHz rating guarantees timing compliance across the full Industrial Plus (-40°C to +105°C) range for SST26VF016BT-80E/MF.
Does SST26VF016BT-80E/MF support Quad I/O mode out of the box?
No, SST26VF016BT-80E/MF powers up in standard SPI mode with SI/SO pins active. Quad I/O mode must be explicitly enabled using the EQIO (38H) command, which configures SIO[3:0] for bidirectional 4-bit operation. The IOC bit in the Configuration register must also be set to '1' before issuing SQI-specific commands like SQOR (6BH) or SQIOR (EBH). Failure to configure IOC first will cause those commands to be ignored - this initialization sequence is mandatory for SST26VF016BT-80E/MF to operate in true SQI mode.
How does the Security ID feature work in SST26VF016BT-80E/MF?
The SST26VF016BT-80E/MF includes a 2 KByte Security ID (Sec ID) space comprising a factory-programmed 64-bit unique identifier (immutable) and a user-programmable area. Users write custom data via the PSID (A5H) command and permanently lock the entire Sec ID space using LSID (85H). Once locked, no further writes are possible - the SEC bit in the Status register becomes '1' and remains so indefinitely. This mechanism enables hardware-rooted device authentication and secure boot binding specific to each SST26VF016BT-80E/MF unit.
Can SST26VF016BT-80E/MF perform erase or program operations while servicing other memory regions?
Yes, SST26VF016BT-80E/MF supports write-suspend functionality. Using the WRSU (B0H) command, an active erase or program operation can be paused to allow immediate read or program access to any unprotected block or sector. The suspended operation resumes automatically upon issuing WRRE (30H). This capability is essential for real-time systems where firmware execution must continue uninterrupted - for example, while updating a secondary bank in SST26VF016BT-80E/MF during active system operation.
What package type is used for SST26VF016BT-80E/MF?
The SST26VF016BT-80E/MF uses an 8-contact WDFN (Wettable Flank Dual No-Lead) package measuring 6 mm × 5 mm. This RoHS-compliant, surface-mount package features exposed paddle thermal pad and wettable flanks for automated optical inspection (AOI) of solder joints. It is distinct from the SOIC and SOIJ variants of the SST26VF016B family - the "/MF" suffix specifically denotes the WDFN-8 package with Industrial Plus temperature rating (-40°C to +105°C) for SST26VF016BT-80E/MF.
