Product details
Overview
SST26WF016BAT-104I/MF from Microchip Technology is a 1.8V, 16 Mbit Serial Quad I/O (SQI) flash memory IC with 104 MHz max clock frequency, 4 KByte uniform sector erase, and 256-byte page programming. It operates within -40°C to +85°C industrial temperature range and supports both SPI and SQI protocols for embedded boot code and firmware storage in space-constrained MCU systems.
For engineers reviewing the SST26WF016BAT-104I/MF datasheet, SST26WF016BAT-104I/MF pinout, SST26WF016BAT-104I/MF application, or SST26WF016BAT-104I/MF equivalent, key selection criteria include single-supply 1.65–1.95 V operation, 100,000-cycle endurance, 100-year data retention, hardware write protection via WP# pin, and flexible block-level security ID programming.
Technical Context
The SST26WF016BAT-104I/MF implements Microchip's SuperFlash® technology with split-gate cells and thick-oxide tunneling, enabling faster erase (18 ms sector, 35 ms chip) and lower energy per operation versus conventional NOR flash. Its dual-mode interface supports legacy SPI (Mode 0/3) and high-speed SQI with four multiplexed I/Os (SIO[3:0]), delivering up to 4× throughput at same clock frequency.
It features a 48-bit Block-Protection Register with individual 8 KByte/32 KByte/64 KByte lock control, volatile Write-Protection Lock-Down (LBPR), and non-volatile nVWLDR for permanent block lockdown. The 2 KByte Security ID includes factory-programmed 64-bit unique ID and user-programmable area, locked via LSID command.

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 W25Q16JWIM (16 Mbit, 1.6–1.95 V) | Same density and voltage; supports octal DTR mode but lacks SQI interface and Security ID OTP | No factory-programmed unique ID; uses standard SFDP instead of proprietary SQI command set | Choose when octal interface or broader SFDP toolchain compatibility is prioritized over hardware security features |
| Cypress S25FL116K0XMFI011 (16 Mbit, 2.7–3.6 V) | Higher voltage range; supports XIP and 133 MHz DDR; no deep power-down or Security ID | Requires level-shifting for 1.8 V systems; lacks OTP ID and nVWLDR for permanent lockdown | Choose only if existing 3.3 V design requires drop-in replacement without voltage rail changes |
Compared with Winbond W25Q16JWIM and Cypress S25FL116K0XMFI011, the SST26WF016BAT-104I/MF uniquely combines 1.8 V operation, SQI throughput, and factory-programmed Security ID-making it optimal for secure, space-constrained, low-power embedded boot applications where identity binding and firmware integrity are mandatory.

FAQ
What is the operating voltage range of the SST26WF016BAT-104I/MF?
The SST26WF016BAT-104I/MF operates from 1.65 V to 1.95 V, optimized for 1.8 V systems. This single-supply range eliminates need for external level shifters when interfacing with modern low-voltage MCUs and SoCs. Operation outside this window may cause unreliable command execution or data corruption. The device draws only 15 mA typical during active read at 104 MHz, supporting energy-efficient designs.
Does the SST26WF016BAT-104I/MF support both SPI and SQI interfaces?
Yes, the SST26WF016BAT-104I/MF supports backward-compatible SPI (Mode 0 and Mode 3) and high-speed SQI protocols. After power-on reset, it defaults to SPI mode; the EQIO command enables SQI mode using SIO[3:0] pins. SQI delivers up to 4× data throughput versus SPI at identical clock frequency, making SST26WF016BAT-104I/MF ideal for bandwidth-intensive firmware loading.
How does hardware write protection work on the SST26WF016BAT-104I/MF?
Hardware write protection on the SST26WF016BAT-104I/MF is controlled by the WP# pin in conjunction with the WPEN bit in the Configuration Register. When WPEN = 1 and IOC = 0, pulling WP# low disables writes to the Block-Protection and Configuration Registers. The SST26WF016BAT-104I/MF ships with WPEN = 0 by default, so WP# is disabled at power-up unless explicitly enabled via WRSR.
What is the purpose of the Security ID feature in the SST26WF016BAT-104I/MF?
The SST26WF016BAT-104I/MF includes a 2 KByte Security ID (Sec ID) with a factory-programmed 64-bit unique identifier and user-programmable area. This enables device authentication and secure firmware binding. Once locked via the LSID command, the entire Sec ID space becomes read-only and cannot be erased or rewritten - a critical capability for anti-counterfeiting and cryptographic key storage in certified embedded systems.
Can the SST26WF016BAT-104I/MF suspend an ongoing erase or program operation?
Yes, the SST26WF016BAT-104I/MF supports write-suspend functionality via the WRSU command. This allows interruption of active sector/block/program operations to service time-critical reads from other memory regions. Status bits WSE and WSP in the Status Register indicate suspend state. Resuming uses WRRE. This capability ensures deterministic response times in real-time systems where SST26WF016BAT-104I/MF serves as primary firmware store.
