Product details
Overview
SST26VF016BAT-104I/MF from Microchip Technology is a 16 Mbit Serial Quad I/O (SQI) flash memory IC operating at 2.3–3.6 V, supporting 104 MHz SPI and 80 MHz SQI read speeds, 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, firmware update buffers, and embedded configuration memory.
For engineers reviewing the SST26VF016BAT-104I/MF datasheet, SST26VF016BAT-104I/MF pinout, SST26VF016BAT-104I/MF application, or SST26VF016BAT-104I/MF equivalent, key selection considerations include quad-I/O burst performance, flexible block protection granularity (8/32/64 KByte overlay blocks), hardware write-protection via WP# pin, Security ID OTP capability, and WDFN-8 package compatibility with space-constrained PCB layouts.
Technical Context
The SST26VF016BAT-104I/MF implements a six-wire SQI interface (SCK, CE#, WP#, HOLD#, and SIO[3:0]) enabling 4-bit multiplexed data transfer, achieving up to 4× bandwidth over standard SPI at identical clock frequency. 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 (x1/x2/x4) after power-on reset, and configurable SQI mode via EQIO command. Mode 0 and Mode 3 clock polarity compatibility ensures interoperability with diverse host controllers, while write-suspend allows interleaved access across protected memory regions during long-duration erase/program operations.

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, 4 KByte sectors, no Security ID OTP | Lacks quad-I/O bandwidth and hardware-secured identity; requires external authentication layer | Select when SQI interface and factory UID are unnecessary and lowest-cost SPI flash suffices |
| Cypress S25FL116K0XMFI011 | 16 Mbit SPI flash with 104 MHz, 4 KByte sectors, no SQI mode, no OTP Security ID | Offers similar endurance/retention but no multiplexed I/O or secure identity features | Choose when legacy SPI compatibility is prioritized over bandwidth and security extensions |
Compared with W25Q16JVSIQ and S25FL116K0XMFI011, the SST26VF016BAT-104I/MF provides measurable advantages in system-level throughput (via SQI), firmware update resilience (via write-suspend), and root-of-trust establishment (via OTP Security ID), making it optimal for next-generation connected devices requiring both performance and security.

FAQ
What is the maximum operating frequency of the SST26VF016BAT-104I/MF under 3.3 V supply?
The SST26VF016BAT-104I/MF supports up to 104 MHz in SPI mode and up to 80 MHz in SQI mode when powered from 2.7–3.6 V. At 3.3 V, the device operates at its rated 104 MHz SPI speed and 80 MHz SQI speed. The 104 MHz rating applies only to SPI x1/x2/x4 reads; SQI mode uses the same clock but achieves higher effective throughput via 4-bit parallel data transfer on SIO[3:0].
Does the SST26VF016BAT-104I/MF support true pin-to-pin compatibility with standard SPI flash devices?
Yes, the SST26VF016BAT-104I/MF is pin-compatible with industry-standard 8-pin SOIC/SOIJ/WDFN SPI flash packages and maintains full command-set compatibility with traditional SPI protocols (x1/x2/x4). Its SIO[3:0] pins default to SI/SO/WP#/HOLD# functions after power-on reset, ensuring drop-in replacement in existing SPI designs without PCB changes.
How does the Security ID feature of the SST26VF016BAT-104I/MF function in practice?
The SST26VF016BAT-104I/MF integrates a 2 KByte Security ID area comprising a factory-programmed 64-bit unique identifier and a user-programmable segment. Users issue PSID commands to write to the user area and LSID to permanently lock both segments. Once locked, no further writes are possible - this enables secure device binding, anti-cloning, and cryptographic key anchoring in safety-critical systems.
Can the SST26VF016BAT-104I/MF be used in both SPI and SQI modes simultaneously?
No, the SST26VF016BAT-104I/MF operates exclusively in either SPI mode (default after power-on reset) or SQI mode (enabled via EQIO command). The IOC bit in the Configuration register selects between SPI pin mapping (WP#/HOLD# active) and SQI pin mapping (SIO2/SIO3 active). Simultaneous operation is not supported; mode switching requires explicit command sequencing and affects pin functionality.
What is the purpose of the Write-Suspend feature in the SST26VF016BAT-104I/MF?
The Write-Suspend feature in the SST26VF016BAT-104I/MF allows a host controller to temporarily halt an ongoing erase or program operation using the WRSU command, then access other unprotected memory regions. This enables real-time systems to maintain responsiveness during long-duration flash operations - for example, servicing sensor interrupts while a firmware block erase proceeds in the background.
