Product details
Overview
SST26VF016BT-104V/SN70SVAO from Microchip Technology is a 16 Mbit Serial Quad I/O™ (SQI™) flash memory IC supporting 2.3–3.6 V single-supply operation, 104 MHz max clock frequency (at 2.7–3.6 V), uniform 4 KByte sector erase, and flexible block protection. It serves as non-volatile program/data storage in microcontroller boot loaders, FPGA configuration, and industrial firmware updates.
For engineers reviewing the SST26VF016BT-104V/SN70SVAO datasheet, SST26VF016BT-104V/SN70SVAO pinout, SST26VF016BT-104V/SN70SVAO application, or SST26VF016BT-104V/SN70SVAO equivalent, key selection criteria include SQI/x4 SPI interface compatibility, 100,000-cycle endurance, OTP Security ID, write-suspend capability, and AEC-Q100 qualification for automotive use.
Technical Context
The SST26VF016BT-104V/SN70SVAO implements a six-wire, 4-bit multiplexed I/O interface (SIO[3:0]) with full backward compatibility to standard SPI (Mode 0/3, x1/x2/x4). Its SuperFlash® split-gate cell architecture enables 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: legacy SPI mode (default at power-up) with separate SI/SO pins, and high-speed SQI mode enabled via EQIO command, where SIO[3:0] carry bidirectional command/address/data. Hardware protection uses WP# and HOLD# pins-active only in SPI mode-and software protection includes volatile lock-down (LBPR) and non-volatile write-lock lock-down (nVWLDR) registers.

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 SPI-only (no SQI), 133 MHz max, no OTP Security ID, no write-suspend, different block protection scheme | Lacks SQI bandwidth and security features; suitable for cost-sensitive non-automotive designs without firmware authentication needs | Select when SQI speed and Security ID are unnecessary and legacy SPI compatibility suffices |
| Cypress S25FL116K0XMFI011 | 16 Mbit, supports both SPI and Quad SPI (QPI), 104 MHz, no OTP ID, no write-suspend, different sector layout (uniform 4 KB only) | Offers QPI mode but lacks non-volatile lock-down and AEC-Q100 qualification; limited to industrial temp (–40°C to +85°C) | Choose for QPI-based systems needing pin-compatible migration from older Spansion parts, not for automotive or secure boot |
Compared with W25Q16JVSIM and S25FL116K0XMFI011, the SST26VF016BT-104V/SN70SVAO uniquely combines AEC-Q100 qualification, OTP Security ID with lockout, write-suspend, and true SQI interface-enabling faster, more secure, and automotive-grade firmware storage where reliability and authentication are critical.

FAQ
What voltage range does the SST26VF016BT-104V/SN70SVAO support for read and write operations?
The SST26VF016BT-104V/SN70SVAO supports single-supply operation from 2.3 V to 3.6 V for both read and write functions. At 2.7–3.6 V, it achieves maximum 104 MHz clock frequency; at 2.3–3.6 V, max frequency is 80 MHz. The device maintains full functionality-including program, erase, and protection features-across this entire voltage range, with no need for auxiliary supplies or level shifters.
Does the SST26VF016BT-104V/SN70SVAO support both SPI and SQI protocols, and how is mode switching handled?
Yes, the SST26VF016BT-104V/SN70SVAO supports both standard SPI (x1/x2/x4, Mode 0/3) and Serial Quad I/O™ (SQI) protocols. It powers up in SPI mode by default. To enter SQI mode, the host must first set the IOC bit (bit 1 of Configuration Register) to '1', then issue the EQIO command (38H). Once configured, SIO[3:0] operate as bidirectional quad I/O lines; reverting to SPI requires RSTQIO (FFH) or power cycle.
What is the purpose and behavior of the HOLD# pin on the SST26VF016BT-104V/SN70SVAO?
The HOLD# pin on the SST26VF016BT-104V/SN70SVAO temporarily suspends active SPI-mode serial communication without resetting internal state or clocking sequence. It is active only in SPI single/dual-bit read mode-not in SQI mode-and requires CE# to be low. When asserted (low), SO enters high-impedance while SI and SCK remain valid. Communication resumes when HOLD# returns high and CE# stays low. The pin is disabled if IOC=1.
How does the Security ID feature work on the SST26VF016BT-104V/SN70SVAO, and can it be reprogrammed?
The SST26VF016BT-104V/SN70SVAO includes a 2 KByte Security ID (Sec ID) space: 64 bits factory-programmed with a unique, unchangeable identifier, plus a user-programmable area. Users write to the latter via PSID command (A5H). Once LSID (85H) is executed, the entire Sec ID space becomes permanently read-only-neither factory nor user portions can be erased or rewritten. This provides immutable device authentication for secure boot and firmware validation.
Is the SST26VF016BT-104V/SN70SVAO qualified for automotive applications, and what does that entail?
Yes, the SST26VF016BT-104V/SN70SVAO is AEC-Q100 qualified (Grade 3: –40°C to +125°C), meaning it has undergone rigorous stress testing-including temperature cycling, HTOL, ESD, and mechanical shock-to ensure reliability in automotive environments. This qualification validates its suitability for engine control, ADAS, infotainment, and telematics systems where failure is not acceptable, and supports compliance with ISO 26262 functional safety requirements when used in appropriate system architectures.
