Product details
Overview
SST26VF016BA-104I/SM from Microchip Technology is a 16 Mbit Serial Quad I/O™ (SQI™) flash memory IC operating at 2.3–3.6V, supporting 104 MHz SPI and 80 MHz SQI read speeds, with uniform 4 KByte sectors, 100,000 program/erase cycles, and industrial temperature range (–40°C to +85°C). It serves as non-volatile code/data storage in microcontroller boot systems, firmware update buffers, and embedded IoT edge nodes.
For engineers reviewing the SST26VF016BA-104I/SM datasheet, SST26VF016BA-104I/SM pinout, SST26VF016BA-104I/SM application, or SST26VF016BA-104I/SM equivalent, key selection considerations include SQI vs. SPI mode compatibility, 8-lead SOIJ package footprint, write-suspend capability for real-time interrupt handling, and OTP Security ID integration for device authentication.
Technical Context
The SST26VF016BA-104I/SM implements a six-wire, 4-bit multiplexed I/O interface (SIO[3:0]) supporting both legacy SPI (Mode 0/3, x1/x2/x4) and high-speed SQI protocols. Its SuperFlash® split-gate cell architecture enables single-supply operation and reduces total energy per erase/program cycle versus conventional NOR flash.
It features dual protection layers: volatile Block-Protection Register (BPR) with lock-down enable (LBPR), and non-volatile Write-Lock Lock-Down Register (nVWLDR) for permanent block-level write disable. The Security ID includes factory-programmed 64-bit unique ID and user-programmable 2 KByte 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 W25Q16JVSIQ | 16 Mbit SPI-only (no SQI); 133 MHz max clock; lacks OTP Security ID and write-suspend | Suitable for cost-sensitive designs without security or real-time suspend requirements | Choose when SQI bandwidth and hardware-level security are not needed; verify SOIJ footprint compatibility |
| Cypress S25FL116K0XMFI011 | 16 Mbit SPI flash with 104 MHz rating; includes sector protection but no OTP ID or nVWLDR lockdown | Targeted at automotive infotainment boot storage where AEC-Q100 qualification is required | Select only if AEC-Q100 Grade 3 (–40°C to +125°C) compliance is mandatory; note different SOIC-8 pinout |
Compared with W25Q16JVSIQ and S25FL116K0XMFI011, the SST26VF016BA-104I/SM uniquely combines SQI bandwidth, write-suspend for deterministic latency, and OTP Security ID - making it optimal for secure, real-time embedded systems where firmware integrity and interrupt responsiveness are critical.

FAQ
What voltage range does the SST26VF016BA-104I/SM support for reliable operation?
The SST26VF016BA-104I/SM operates across 2.3–3.6V, with maximum 104 MHz performance guaranteed only at 2.7–3.6V. At the lower 2.3–2.7V range, clock speed is limited to 80 MHz. This dual-voltage capability allows direct integration into mixed-supply systems without level-shifting, and its SuperFlash® technology ensures consistent endurance and retention across the full range.
Does the SST26VF016BA-104I/SM support true quad I/O mode, and how is it enabled?
Yes, the SST26VF016BA-104I/SM supports true quad I/O (SQI) mode using all four SIO pins (SIO[3:0]) for simultaneous command/address/data transfer. It is enabled by issuing the EQIO (38H) command after setting the IOC bit in the Configuration Register to '1'. Unlike SPI mode, SQI mode disables HOLD# and WP# functions and requires no additional hardware configuration.
How does the write-suspend feature of the SST26VF016BA-104I/SM improve real-time system responsiveness?
The SST26VF016BA-104I/SM supports write-suspend (WRSU command) to pause an ongoing Program or Erase operation, allowing immediate access to other memory regions for time-critical reads or commands. This avoids blocking the host MCU for up to 35 ms during chip erase, enabling deterministic interrupt handling - a key advantage over standard SPI flash in safety-critical or real-time control loops.
What security mechanisms does the SST26VF016BA-104I/SM provide beyond basic write protection?
Beyond standard block-protection registers, the SST26VF016BA-104I/SM provides three hardened security layers: (1) One-Time Programmable (OTP) 2 KByte Security ID with factory 64-bit unique ID, (2) non-volatile Write-Lock Lock-Down Register (nVWLDR) for permanent block lockdown, and (3) LSID command to permanently lock the entire Security ID space. These features collectively prevent cloning, unauthorized firmware modification, and runtime tampering.
Is the SST26VF016BA-104I/SM pin-compatible with standard 8-lead SOIC or SOIJ SPI flash devices?
Yes, the SST26VF016BA-104I/SM in SOIJ package shares identical pinout, footprint, and signal mapping with industry-standard 8-lead SOIC/SOIJ SPI flash devices (e.g., pin 1 = CE#, pin 2 = SO/SIO1, pin 3 = WP#/SIO2, etc.). This enables drop-in replacement in existing layouts - though SQI functionality requires firmware updates to issue EQIO and use SIO[3:0] commands.
