Product details
Overview
SST26WF016BAT-104I/CS from Microchip Technology is a 1.8V, 16 Mbit Serial Quad I/O (SQI) flash memory IC designed for high-speed, low-power embedded storage in space-constrained applications. It delivers 104 MHz max clock frequency, 4 KByte uniform sector erase, 256-byte page programming, and operates across -40°C to +85°C industrial temperature range.
For engineers reviewing the SST26WF016BAT-104I/CS datasheet, SST26WF016BAT-104I/CS pinout, SST26WF016BAT-104I/CS application, or SST26WF016BAT-104I/CS equivalent, key selection criteria include SQI/x4 SPI interface compatibility, single 1.65–1.95V supply operation, hardware write protection (WP#), hold functionality, and factory-programmed 64-bit Security ID with user-programmable 2 KByte OTP area.
Technical Context
The SST26WF016BAT-104I/CS implements a six-wire, 4-bit multiplexed I/O interface supporting both Mode 0 and Mode 3 SPI timing, with backward-compatible x1/x2/x4 command structure. Its SuperFlash® split-gate CMOS technology enables 100,000 program/erase cycles and >100 years data retention.
It features dual configuration variants: SST26WF016B defaults with WP# and HOLD# enabled at power-up (IOC = 0), while SST26WF016BA defaults with them disabled (IOC = 1). This specific variant - SST26WF016BAT-104I/CS - uses the 8-contact WDFN (6 mm × 5 mm) package and supports write-suspend, deep power-down (2.5 μA), and flexible block protection including volatile lock-down and non-volatile one-time programmable (OTP) 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 W25Q16JVSNIQ | 16 Mbit, 1.7–2.0 V supply, 133 MHz max, standard SPI only (no SQI), no integrated Security ID | Lacks SQI interface and OTP security features; suitable where higher clock speed offsets missing quad I/O | Select when SQI is unnecessary and maximum SPI clock speed is prioritized over security and low-voltage operation |
| Cypress S25FL116K0XMFI011 | 16 Mbit, 2.7–3.6 V supply, 80 MHz max, supports QPI but not SQI, includes 64-bit UID but no user-programmable Security ID area | Requires 3.3V supply; incompatible with 1.8V systems; lacks user-configurable OTP security space | Choose only for legacy 3.3V designs requiring QPI compatibility and basic UID - not drop-in for SST26WF016BAT-104I/CS |
Compared with W25Q16JVSNIQ and S25FL116K0XMFI011, the SST26WF016BAT-104I/CS uniquely combines 1.8V operation, SQI interface, deep power-down, and user-programmable 2 KByte Security ID - making it optimal for next-generation ultra-low-power, secure, space-constrained embedded systems.

FAQ
What is the operating voltage range for the SST26WF016BAT-104I/CS?
The SST26WF016BAT-104I/CS operates from 1.65 V to 1.95 V - a tightly regulated 1.8 V nominal supply. This single-voltage design eliminates need for external level shifters when interfacing with 1.8 V microcontrollers or FPGAs, and ensures compatibility with modern low-power SoCs. Operation outside this range may cause unreliable read/write behavior or damage.
Does the SST26WF016BAT-104I/CS support both SPI and SQI protocols?
Yes, the SST26WF016BAT-104I/CS supports full backward-compatible SPI (x1/x2/x4) and high-speed Serial Quad I/O (SQI) modes. After power-on reset, it defaults to SPI mode; SQI mode is enabled by setting the IOC bit in the Configuration Register and issuing the EQIO command. The SQI interface uses SIO[3:0] for bidirectional 4-bit data transfer, quadrupling effective bandwidth at the same clock frequency.
How does the Security ID feature work in the SST26WF016BAT-104I/CS?
The SST26WF016BAT-104I/CS includes a 2 KByte Security ID (Sec ID) area comprising a factory-programmed 64-bit unique identifier and a user-programmable segment. Users can write custom data using the PSID command and permanently lock the entire Sec ID space using the LSID command. Once locked, no further writes are possible - enabling secure device authentication, firmware binding, and anti-cloning in production environments.
What package type is used for the SST26WF016BAT-104I/CS?
The SST26WF016BAT-104I/CS is packaged in an 8-contact WDFN (6 mm × 5 mm) with exposed pad, compliant with JEDEC MO-229 and RoHS standards. This compact, thermally enhanced package supports automated reflow assembly and provides superior thermal performance versus SOIC, making it ideal for dense, thermally constrained PCB layouts in portable and industrial equipment.
Can the SST26WF016BAT-104I/CS be used in automotive applications?
The SST26WF016BAT-104I/CS is rated for industrial temperature range (–40°C to +85°C) and meets RoHS requirements, but it is not AEC-Q100 qualified. While it may function in some automotive cabin or infotainment applications, Microchip does not certify it for under-hood or safety-critical ADAS use. For automotive-grade deployment, consult Microchip's AEC-Q100 qualified SST26VF016B or equivalent qualified variants.
