Product details
Overview
SST26VF016BT-104I/SN70SVAO 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 systems, firmware update modules, and embedded edge devices.
For engineers reviewing the SST26VF016BT-104I/SN70SVAO datasheet, SST26VF016BT-104I/SN70SVAO pinout, SST26VF016BT-104I/SN70SVAO application, or SST26VF016BT-104I/SN70SVAO equivalent, key selection considerations include SQI vs. SPI mode configuration, 4 KByte sector erase granularity, hardware write protection via WP# pin, Security ID OTP capability, and WDFN-8 (6 mm × 5 mm) package compatibility with high-density PCB layouts.
Technical Context
The SST26VF016BT-104I/SN70SVAO implements a six-wire, 4-bit multiplexed I/O interface (SIO[3:0]) enabling quad-data-rate transfers while maintaining backward compatibility with standard SPI Mode 0/3. 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 flexible protection schemes including individual block write-lock (via 48-bit Block-Protection Register), volatile lock-down (LBPR), and non-volatile write-lock lock-down (nVWLDR), plus factory-programmed 64-bit unique Security ID with user-programmable 2 KByte area. The device defaults to SPI mode at power-up and requires IOC bit setting to enable SQI functionality.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CE# | Chip Enable | Active-low chip select; must remain low throughout command sequence - enables multi-device SPI bus sharing |
| SIO0 (SI) | Serial Data Input | Default SPI input pin; latched on rising SCK edge - used for command/address/data input in x1 mode |
| SIO1 (SO) | Serial Data Output | Default SPI output pin; driven on falling SCK edge - provides status register, memory, or ID data in x1 mode |

Key Features
| Feature | Design Value |
|---|---|
| Serial Quad I/O™ (SQI™) Interface | Enables 4-bit multiplexed data transfer on SIO[3:0], quadrupling effective bandwidth over standard SPI at identical clock frequency - reduces firmware load time in resource-constrained hosts |

| Write-Suspend Capability | WRSU/WRRE instructions allow suspension of active Program or Erase operations to service higher-priority reads - ensures deterministic real-time response in multitasked systems |
Applications
| Industrial HMI Boot Storage | Automotive Telematics Firmware |
|---|---|
Use Scenario: Storing boot code and GUI assets for ARM Cortex-M7-based human-machine interface panels in factory automation cabinets. IC Role / Device Role / Timing Role: Primary nonvolatile code storage executing XIP-capable firmware during cold start; accessed via SPI at 80 MHz for fast UI initialization. Use Value: 104 MHz SQI mode reduces boot time by 65% vs. legacy SPI flash; 4 KByte sector granularity enables atomic OTA patch updates without erasing full image. | Use Scenario: Holding certified firmware images and cryptographic keys in AEC-Q100 qualified telematics control units (TCUs) for over-the-air (OTA) updates. IC Role / Device Role / Timing Role: Secure firmware repository with read-lock enabled on 8 KByte parameter blocks containing ECUs' VIN and calibration data. Use Value: Factory-programmed 64-bit Security ID binds firmware signature verification to hardware identity; nVWLDR prevents tampering with critical lock-down bits post-deployment. |
| Edge Gateway Configuration | Medical Sensor Calibration Storage |
Use Scenario: Persisting network credentials, sensor calibration coefficients, and device-specific settings in battery-powered LoRaWAN gateways deployed outdoors. IC Role / Device Role / Timing Role: Low-power configuration store accessed intermittently via SPI; deep power-down (DPD) mode draws only 15 µA standby current. Use Value: 15 µA typical standby current extends 10-year battery life; individual block write-protection isolates sensitive Wi-Fi PSKs from field-updatable telemetry parameters. | Use Scenario: Archiving factory-calibrated gain/offset values and medical device certification metadata in portable ultrasound transducers. IC Role / Device Role / Timing Role: Tamper-evident calibration vault using read-locked 8 KByte parameter blocks and permanent nVWLDR lock-down of BPR bits.

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 W25Q16JVSNIQ | 16 Mbit SPI flash, no SQI support; 133 MHz max (3.3 V), 100,000 endurance, same SOIC-8/WSON-8 packages | Lacks quad I/O interface and Security ID; uses standard SPI command set only | Select when SQI bandwidth or hardware-secured ID are not required and legacy SPI design reuse is prioritized |
| Cypress S25FL116K0XMFI011 | 16 Mbit FL-S family; supports octal DTR mode (not SQI); 100,000 endurance; -40°C to +85°C; WSON-8 | Higher pin-count octal interface; no OTP Security ID; different status/configuration register map | Select when migrating to higher-speed octal interface and Cypress's FL-S ecosystem toolchain is already in use |
Compared with SST26VF016BT-104I/SN70SVAO, W25Q16JVSNIQ offers higher SPI clock speed but no SQI acceleration or Security ID, while S25FL116K0XMFI011 provides octal DTR performance at cost of pin count and register incompatibility - SST26VF016BT-104I/SN70SVAO uniquely balances SQI bandwidth, integrated security, and drop-in WDFN-8 footprint.

FAQ
What is the maximum clock frequency supported by SST26VF016BT-104I/SN70SVAO?
The SST26VF016BT-104I/SN70SVAO supports up to 104 MHz when operated within the 2.7–3.6 V supply range, and up to 80 MHz at 2.3–3.6 V or under extended temperature conditions (–40°C to +125°C). This frequency applies to both SPI and SQI read operations, with SQI achieving four times the data throughput of standard SPI at the same clock rate due to its 4-bit multiplexed I/O architecture.
Does SST26VF016BT-104I/SN70SVAO support both SPI and SQI interfaces simultaneously?
No - the SST26VF016BT-104I/SN70SVAO defaults to standard SPI mode after power-on reset and requires explicit configuration (setting the IOC bit and issuing EQIO command) to enter SQI mode. Once in SQI mode, the device uses SIO[3:0] for bidirectional quad-data transfers; it cannot operate both protocols concurrently. Mode switching requires a reset or RSTQIO command to revert to SPI.
How is hardware write protection implemented on SST26VF016BT-104I/SN70SVAO?
Hardware write protection on SST26VF016BT-104I/SN70SVAO is controlled by the WP# pin in conjunction with the WPEN and IOC bits in the Configuration register. When IOC = 0 and WPEN = 1, driving WP# low disables writes to the Block-Protection and Configuration registers only. The factory default sets WPEN = 0, disabling WP# functionality until explicitly enabled - this prevents unintended lockout during system bring-up.
What is the purpose and structure of the Security ID feature in SST26VF016BT-104I/SN70SVAO?
The SST26VF016BT-104I/SN70SVAO includes a 2 KByte Security ID (Sec ID) space comprising a factory-programmed 64-bit unique identifier (read-only, unchangeable) and a user-programmable area. The Sec ID can be locked permanently using the LSID command, preventing further writes. This feature enables hardware-rooted device authentication, firmware binding, and secure provisioning in trusted execution environments.
Can SST26VF016BT-104I/SN70SVAO perform erase or program operations while servicing read requests?
Yes - the SST26VF016BT-104I/SN70SVAO supports Write-Suspend functionality. Using the WRSU command, an active Program or Erase operation can be suspended to allow immediate read access to other memory regions. The WRRE command resumes the suspended operation. This capability ensures deterministic latency for time-critical reads without aborting long-duration flash operations.
