Product details
Overview
SST26VF016B-104V/SN from Microchip Technology is a 16 Mbit Serial Quad I/O™ (SQI™) flash memory IC operating at 2.7–3.6 V with 104 MHz max clock frequency, supporting x1/x2/x4 SPI and full SQI protocols, and featuring uniform 4 KByte sectors, 100,000 write/erase endurance, and industrial temperature range (–40°C to +85°C). It serves as nonvolatile code/data storage in microcontroller boot loaders and firmware update modules.
For engineers reviewing the SST26VF016B-104V/SN datasheet, SST26VF016B-104V/SN pinout, SST26VF016B-104V/SN application, or SST26VF016B-104V/SN equivalent, key selection considerations include SQI vs. SPI mode configuration, sector/block protection granularity, Security ID OTP capability, and WDFN-8 (6 mm × 5 mm) package compatibility with high-density PCB layouts.
Technical Context
The SST26VF016B-104V/SN implements a six-wire, 4-bit multiplexed I/O interface (SIO[3:0]) enabling quad-data-rate transfers while maintaining full command-set compatibility with legacy SPI devices. Its SuperFlash® split-gate cell architecture delivers faster erase (sector: 18 ms typ) and lower active current (15 mA @ 104 MHz) versus conventional NOR flash.
It supports dual bus modes - Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1) - with SCK sampling on rising edge for input and output shifting on falling edge. Hardware protection uses WP# and HOLD# pins, active only in SPI single/dual mode, while SQI mode disables those pins and enables full quad I/O operation via EQIO 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 W25Q16JVSIM | 16 Mbit, 133 MHz max, standard SPI-only (no SQI), 4 KByte sectors, 100K endurance | Lacks quad I/O and Security ID; simpler protection model (no nVWLDR or OTP Sec ID) | Choose when SQI bandwidth and cryptographic identity features are unnecessary and cost sensitivity is high. |
| Cypress S25FL116K0XMFI011 | 16 Mbit, 104 MHz, supports both SPI and QPI modes, 4 KByte sectors, 100K endurance, no OTP Security ID | QPI mode offers quad-speed but lacks dedicated Security ID OTP area and flexible overlay block structure | Prefer when migrating from legacy Cypress platforms; avoid if device authentication or parameter-block isolation is required. |
Compared with W25Q16JVSIM and S25FL116K0XMFI011, the SST26VF016B-104V/SN uniquely combines SQI protocol efficiency, factory-programmed 64-bit Security ID, and granular non-volatile block lock-down - making it optimal for secure, high-throughput embedded boot and update architectures.

FAQ
What voltage range does the SST26VF016B-104V/SN support for 104 MHz operation?
The SST26VF016B-104V/SN supports 104 MHz maximum clock frequency only within the 2.7–3.6 V supply range. Operation at 2.3–3.6 V reduces max frequency to 80 MHz. This voltage-frequency dependency is enforced by internal charge pump regulation and must be observed in layout and power design to ensure reliable SST26VF016B-104V/SN timing compliance.
Does the SST26VF016B-104V/SN support true pin-compatible replacement for standard SPI flash devices?
Yes - the SST26VF016B-104V/SN is pin-compatible with industry-standard 8-pin SOIC, SOIJ, and WDFN packages used by legacy SPI flash, including identical pin functions for CE#, SCK, SI, SO, WP#, HOLD#, VDD, and VSS in SPI mode. The SST26VF016B-104V/SN maintains backward compatibility without PCB changes when operated in default SPI mode.
How is the Security ID implemented in the SST26VF016B-104V/SN, and can it be reprogrammed?
The SST26VF016B-104V/SN includes a 2 KByte Security ID area: 64 bits are factory-programmed and immutable; the remainder is user-programmable. Once locked via LSID command, no further writes are possible. Neither segment supports erasure. This one-time programmability ensures cryptographic binding in the SST26VF016B-104V/SN for secure boot and device identity verification.
What is the purpose of the IOC bit in the SST26VF016B-104V/SN Configuration Register?
The IOC (I/O Configuration) bit in the SST26VF016B-104V/SN Configuration Register selects between SPI pin mapping (IOC=0, enabling WP# and HOLD#) and SQI pin mapping (IOC=1, repurposing SIO2/SIO3 for quad I/O). It must be set before issuing SQI-specific commands like SQOR or SQIOR. Default power-up state is IOC=0, ensuring safe SPI-mode initialization for the SST26VF016B-104V/SN.
Can the SST26VF016B-104V/SN perform simultaneous read and write operations?
No - the SST26VF016B-104B-104V/SN does not support true concurrent read/write. However, its Write-Suspend feature allows pausing an active erase or program operation to execute a read from another block/sector, then resuming the suspended operation. This pseudo-concurrency improves real-time responsiveness without hardware multi-bank architecture, a key capability of the SST26VF016B-104V/SN in interrupt-driven systems.
