Product details
Overview
SST26VF016B-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), supporting x1/x2/x4 SPI and full SQI protocols, with uniform 4 KByte sectors, 100,000 write/erase cycles endurance, and industrial temperature range (–40°C to +85°C). It serves as non-volatile program/data storage in microcontroller boot loaders and firmware update modules.
For engineers reviewing the SST26VF016B-104I/MF datasheet, SST26VF016B-104I/MF pinout, SST26VF016B-104I/MF application, or SST26VF016B-104I/MF equivalent, key selection criteria include quad-I/O throughput, sector-level write protection granularity, Security ID OTP capability, and compatibility with both legacy SPI and high-speed SQI host controllers.
Technical Context
The SST26VF016B-104I/MF implements a six-wire, 4-bit multiplexed serial interface (SIO[3:0]) with configurable Mode 0/Mode 3 clock polarity, enabling true quad-data-rate transfers without increasing pin count. Its SuperFlash® split-gate cell architecture delivers faster erase (18 ms sector, 35 ms chip) and lower active current (15 mA @ 104 MHz) versus conventional NOR flash.
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) via EQIO command. Hardware write protection (WP#) and HOLD# are functional only in SPI single/dual modes-not in SQI-and require IOC bit = 0 in the Configuration register.

Package: 8-contact WDFN (6 mm × 5 mm), RoHS-compliant, moisture-sensitive level 3.
| Pin/Terminal | Circuit Role | Design Meaning |

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, 133 MHz max, 1.65–3.6 V supply, no SQI support-SPI-only with DTR capability; lacks Security ID and nVWLDR | Better suited for cost-sensitive consumer electronics where quad I/O is unnecessary and security features are omitted | Select W25Q16JW only if SQI bandwidth is not required and Security ID is unused; verify 1.65 V min supply compatibility with host system |
| Cypress S25FL116K | 16 Mbit, 104 MHz max, 2.7–3.6 V, supports XIP and DDR mode; includes 64-bit unique ID but no user-programmable Security ID space | Preferred for high-reliability aerospace applications requiring extended temperature screening and QML-Q qualification | Choose S25FL116K when radiation tolerance or MIL-PRF-38535 compliance is mandatory; note absence of OTP user-programmable security area |
Compared with SST26VF016B-104I/MF, W25Q16JW trades SQI performance and security for broader voltage range and lower cost, while S25FL116K emphasizes process reliability over flexible block protection and user-configurable security-making SST26VF016B-104I/MF optimal for automotive and industrial designs needing both speed and layered security.

FAQ
What is the maximum clock frequency supported by SST26VF016B-104I/MF?
The SST26VF016B-104I/MF supports up to 104 MHz when powered at 2.7–3.6 V, and up to 80 MHz at 2.3–3.6 V. This frequency applies to both SPI and SQI modes, though SQI achieves four times the data throughput due to its 4-bit I/O structure. The 104 MHz rating is validated for industrial temperature range (–40°C to +85°C); at extended temperature (125°C), the maximum frequency is limited to 80 MHz.
Does SST26VF016B-104I/MF support true quad-I/O mode out of the box?
No-SST26VF016B-104I/MF powers up in standard SPI mode (using SI/SO pins) and requires explicit configuration to enter SQI mode. The host must first set the IOC bit in the Configuration register to '1', then issue the EQIO (0x38) command. Only after this sequence do the SIO[3:0] pins become fully bidirectional for quad-data-rate operation.
How does the Security ID feature work in SST26VF016B-104I/MF?
The SST26VF016B-104I/MF includes a 2 KByte Security ID (Sec ID) space: the first 64 bits are factory-programmed and globally unique, while the remaining 2040 bytes are user-programmable. Access requires PSID (Program Security ID) and LSID (Lockout Security ID) commands. Once LSID is executed, the entire Sec ID space becomes permanently read-only-neither factory nor user portions can be altered or erased.
Can SST26VF016B-104I/MF be used in automotive applications?
Yes-SST26VF016B-104I/MF is AEC-Q100 qualified for automotive Grade 3 (–40°C to +85°C), making it suitable for engine control units, body control modules, and ADAS subsystems. Its 100,000-cycle endurance, 100-year data retention, and hardware write protection (WP#) support robust firmware storage requirements in safety-critical automotive environments.
What package options are available for SST26VF016B-104I/MF?
The SST26VF016B-104I/MF is offered in three RoHS-compliant packages: 8-contact WDFN (6 mm × 5 mm), 8-lead SOIJ (5.28 mm width), and 8-lead SOIC (3.90 mm width). The "/MF" suffix in the part number specifically denotes the 8-contact WDFN package. Pin assignments are identical across packages; only mechanical dimensions and thermal characteristics differ.
