Product details
Overview
SST26VF016B-104I/SN70SVAO from Microchip Technology is a 16 Mbit Serial Quad I/O™ (SQI™) flash memory IC operating at up to 104 MHz (2.7–3.6V), supporting x1/x2/x4 SPI and 4-bit SQI protocols, with uniform 4 KByte sectors, 100,000 write/erase 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/SN70SVAO datasheet, SST26VF016B-104I/SN70SVAO pinout, SST26VF016B-104I/SN70SVAO application, or SST26VF016B-104I/SN70SVAO equivalent, key selection criteria include quad-I/O throughput, sector-level write protection granularity, deep power-down current (15 µA), security ID OTP capability, and AEC-Q100 qualification for automotive use.
Technical Context
The SST26VF016B-104I/SN70SVAO implements a six-wire SQI interface (SCK, CE#, WP#, HOLD#, VDD, VSS, plus SIO[3:0] multiplexed I/O) enabling 4-bit data transfer per clock cycle, doubling bandwidth over standard SPI at identical frequency. Its SuperFlash® split-gate CMOS technology delivers faster erase (sector: 18 ms typ) and lower total energy per operation versus conventional NOR flash.
It supports dual operational modes: default SPI mode (Mode 0/3, SI/SO pins) and configurable SQI mode (SIO[3:0] multiplexed), with hardware write protection via WP# pin (when IOC=0 and WPEN=1) and flexible software block protection using a 48-bit Block-Protection Register and non-volatile lock-down bits.

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 W25Q16JVSIQ | 16 Mbit SPI-only (no SQI); 133 MHz max; 100K endurance; no Security ID OTP; SOIC-8 package only. | Lacks quad-I/O bandwidth and hardware-secured identity; suitable for cost-sensitive SPI-only designs without AEC-Q100 requirement. | Select when SQI speed and automotive qualification are unnecessary, and SOIC-8 footprint is preferred. |
| Cypress S25FL116K0XMFI011 | 16 Mbit SPI/QPI; 85 MHz max; 100K endurance; no OTP Security ID; supports QPI but not SQI; WSON-8 package. | Offers QPI mode for higher throughput than SPI but lacks SQI's pin-efficiency and Microchip's SuperFlash® erase speed (25 ms max vs. 18 ms typ). | Choose for legacy QPI-based platforms needing drop-in replacement where SQI-specific features are unused. |
Compared with W25Q16JVSIQ and S25FL116K0XMFI011, the SST26VF016B-104I/SN70SVAO uniquely combines AEC-Q100 qualification, SQI interface for minimal pin count, factory-programmed 64-bit Security ID, and fastest sector erase (18 ms typ), making it optimal for space-constrained, security-aware automotive and industrial firmware storage.

FAQ
What is the maximum clock frequency supported by SST26VF016B-104I/SN70SVAO?
The SST26VF016B-104I/SN70SVAO supports up to 104 MHz when operated within the 2.7–3.6V supply range, and up to 80 MHz at 2.3–3.6V. This frequency applies to both SPI and SQI modes, with SQI achieving four times the data throughput per clock cycle due to its 4-bit multiplexed I/O architecture. The "104" in the part number explicitly denotes this 104 MHz rating.
Does SST26VF016B-104I/SN70SVAO support AEC-Q100 qualification?
Yes, the SST26VF016B-104I/SN70SVAO is explicitly AEC-Q100 qualified for automotive applications, as confirmed in the official Microchip datasheet DS20005262F. This qualification covers stress testing for temperature cycling, humidity, and electrical robustness, validating its use in engine control units, ADAS modules, and other automotive subsystems requiring high reliability.
How does the Security ID feature work in SST26VF016B-104I/SN70SVAO?
The SST26VF016B-104I/SN70SVAO 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 one-time programmable and immutable; the user area can be written via PSID command and permanently locked with LSID. Once locked, no further writes are possible - a critical anti-cloning measure for firmware authentication.
What package type is used for SST26VF016B-104I/SN70SVAO?
The SST26VF016B-104I/SN70SVAO is packaged in an 8-contact WDFN (6 mm × 5 mm) with exposed pad, as specified in the Microchip datasheet DS20005262F. This compact, thermally enhanced package supports automated assembly and provides superior thermal performance compared to SOIC-8, while maintaining compatibility with standard reflow profiles.
Can SST26VF016B-104I/SN70SVAO operate in both SPI and SQI modes?
Yes, the SST26VF016B-104I/SN70SVAO powers up in SPI mode (default) supporting x1/x2/x4 protocols and Mode 0/3 clock polarity. It can be transitioned to SQI mode via the EQIO command, enabling 4-bit multiplexed I/O on SIO[3:0]. The IOC bit in the Configuration Register controls pin function mapping, and SQI mode disables HOLD# and WP# functionality - a deliberate architectural trade-off for bandwidth efficiency.
