Product details
Overview
SST26VF016B-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 SST26VF016B-80E/MF datasheet, SST26VF016B-80E/MF pinout, SST26VF016B-80E/MF application, or SST26VF016B-80E/MF equivalent, key selection criteria include SQI vs. SPI mode compatibility, 80 MHz timing at 2.3–3.6 V, WDFN-8 package dimensions, sector erase granularity, and hardware write-protection via WP# pin.
Technical Context
The SST26VF016B-80E/MF implements a six-wire, 4-bit multiplexed I/O interface (SIO[3:0]) enabling quad-speed data transfer while maintaining full command-set compatibility with legacy SPI protocols (Mode 0/3). Its SuperFlash® split-gate cell architecture delivers 100,000 program/erase cycles and >100-year data retention.
It supports dual operational modes: default SPI mode (SI/SO pins) after power-on reset, and configurable SQI mode (SIO[3:0] multiplexed I/O) enabled via EQIO command. Write-suspend, deep power-down (DPD), and configurable hold functionality are implemented in hardware with dedicated HOLD# and WP# pins active only in SPI 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 W25Q16JW | 16 Mbit, 1.65–3.6 V supply, 133 MHz max (1.8 V), no SQI interface - uses standard QPI/DTR | Lacks SQI protocol and 2.3 V low-voltage support; requires different driver stack | Select if higher speed at 1.8 V is needed and SQI compatibility is not required |
| Cypress S25FL116K | 16 Mbit, 2.7–3.6 V only, 80 MHz max, no OTP Security ID or nVWLDR lock-down | No factory-unique ID or permanent block lock-down - insufficient for security-critical use cases | Select for cost-sensitive industrial applications where advanced security features are unnecessary |
Compared with Winbond W25Q16JW and Cypress S25FL116K, the SST26VF016B-80E/MF uniquely combines 2.3 V operation, SQI interface, OTP Security ID, and non-volatile block lock-down - making it the only option meeting full requirements for secure, low-voltage, high-throughput embedded firmware storage.

FAQ
What voltage range does the SST26VF016B-80E/MF support, and how does it affect maximum clock speed?
The SST26VF016B-80E/MF operates from 2.3 V to 3.6 V. At 2.3–3.6 V, its maximum clock frequency is 80 MHz; at 2.7–3.6 V, it supports up to 104 MHz. The SST26VF016B-80E/MF datasheet specifies that the 80 MHz rating applies across the full 2.3–3.6 V range, making it suitable for 2.5 V systems where higher-voltage variants cannot operate. This dual-voltage capability ensures design flexibility without sacrificing performance.
Does the SST26VF016B-80E/MF support both SPI and SQI interfaces, and how is mode switching handled?
Yes, the SST26VF016B-80E/MF powers up in SPI mode (using SI/SO pins) for backward compatibility and can be switched to SQI mode using the EQIO command. In SQI mode, SIO[3:0] become bidirectional, enabling quad-speed transfers. The IOC bit in the Configuration register must be set to '1' before issuing SQI-specific commands like SQOR or SQIOR. The SST26VF016B-80E/MF retains full SPI command-set compatibility regardless of mode, simplifying firmware migration.
What is the purpose of the Security ID feature in the SST26VF016B-80E/MF, and how is it protected?
The SST26VF016B-80E/MF includes a 2 KByte Security ID (Sec ID) space comprising a factory-programmed 64-bit unique identifier and a user-programmable area. The factory ID is immutable; the user area can be written once using PSID and permanently locked with LSID. Once locked, no further writes are possible - ensuring cryptographic key or device identity integrity. This Sec ID implementation is integral to the SST26VF016B-80E/MF's role in secure boot and anti-counterfeiting systems.
How does the SST26VF016B-80E/MF implement hardware write protection, and what pins are involved?
The SST26VF016B-80E/MF uses the WP# pin in conjunction with the WPEN bit (non-volatile) and IOC bit in the Configuration register. WP# is active-low and only functional in SPI mode when IOC = 0 and WPEN = 1. It protects only the Block-Protection and Configuration registers - not main memory - allowing firmware updates while preventing accidental register corruption. The SST26VF016B-80E/MF defaults to WPEN = 0 at power-up, disabling hardware protection until explicitly enabled.
What package options are available for the SST26VF016B-80E/MF, and which one corresponds to the -80E/MF suffix?
The SST26VF016B-80E/MF suffix denotes the 8-contact WDFN package (6 mm × 5 mm, 0.5 mm pitch). Other package options for the SST26VF016B family include 8-lead SOIJ (5.28 mm) and 8-lead SOIC (3.90 mm), but the -80E/MF variant is exclusively offered in WDFN. This compact, thermally efficient package supports high-density PCB layouts and meets JEDEC moisture sensitivity level 3 requirements.
