Product details
Overview
SST26VF016BEUI-104I/SN from Microchip Technology is a 16 Mbit Serial Quad I/O™ (SQI™) flash memory IC with factory-programmed EUI-48™ and EUI-64™ identifiers, supporting 104 MHz read speed at 2.7–3.6 V and 80 MHz at 2.3–3.6 V, 4 KByte uniform sectors, and industrial temperature range (–40°C to +85°C), deployed in embedded boot code storage and firmware update systems.
For engineers reviewing the SST26VF016BEUI-104I/SN datasheet, SST26VF016BEUI-104I/SN pinout, SST26VF016BEUI-104I/SN application, or SST26VF016BEUI-104I/SN equivalent, key selection considerations include SQI vs. SPI mode compatibility, EUI-48/EUI-64 accessibility via SFDP, write-suspend capability for real-time firmware updates, and OTP Security ID programmability for device authentication.
Technical Context
The SST26VF016BEUI-104I/SN implements a six-wire, 4-bit multiplexed I/O interface (SIO[3:0]) supporting both legacy SPI (x1/x2) and high-speed SQI (x4) protocols, with Mode 0 and Mode 3 clock polarity support. Its SuperFlash® split-gate cell architecture enables 100,000 program/erase cycles and >100-year data retention.
It features dual protection layers: volatile Block-Protection Register (BPR) with per-block write/read lock control, and non-volatile Write-Lock Lock-Down register (nVWLDR) for permanent OTP block protection. The device ships with IOC=0 (HOLD#/WP# enabled) and WPEN=0 (hardware write protection disabled by default).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (2 MByte) organized as uniform 4 KByte sectors plus eight 8 KByte, two 32 KByte, and thirty 64 KByte overlay blocks. |
| Interface Protocol | Supports SPI x1/x2 and SQI x4 modes; initial power-on state is SPI mode; EQIO command enables quad I/O operation. |
| Max Clock Frequency | 104 MHz (2.7–3.6 V supply); 80 MHz (2.3–3.6 V supply); burst reads achieve up to 416 MB/s effective throughput in SQI mode. |
| Erase Performance | Sector/Block erase: 18 ms typical (25 ms max); chip erase: 35 ms typical (50 ms max); enables fast field firmware recovery. |
| Endurance & Retention | 100,000 program/erase cycles minimum; >100 years data retention at 85°C - suitable for long-lifecycle industrial deployments. |
| Power Consumption | 15 mA active read current @ 104 MHz; 15 µA standby current - reduces system-level power budget in always-on edge nodes. |
| Security Features | Factory-programmed EUI-48/EUI-64 in SFDP table; 2 KByte OTP Security ID space with user-programmable segment and LSID lockout. |
Pinout & Package
Package: 8-lead SOIC (3.90 mm width), RoHS-compliant, industrial temperature grade (–40°C to +85°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CE# | Chip Enable | Active-low enable signal; must remain low throughout command sequence; controls device selection on shared bus. |
| SIO0 (SI) | Serial Data Input (SPI default) | Primary input for commands, addresses, and data in SPI mode; latched on SCK rising edge. |
| SIO1 (SO) | Serial Data Output (SPI default) | Primary output for read data in SPI mode; shifted out on SCK falling edge. |
| SIO2 (WP#) | Write Protect / Quad I/O | In SPI mode: hardware write-protection pin (when WPEN=1 & IOC=0); in SQI mode: bidirectional data line. |
| VSS | Ground | Reference ground for all I/O and core logic; requires low-impedance connection to minimize noise coupling. |
| VDD | Power Supply | Single supply: 2.3–3.6 V; supports wide-input voltage tolerance for flexible system power rail design. |
| SIO3 (HOLD#) | Hold / Quad I/O | In SPI mode: pauses ongoing serial transfer without resetting clock state; must be tied high when unused. |
| SCK | Serial Clock | Master-generated clock; rising edge latches inputs, falling edge outputs data; defines timing for all serial operations. |
Key Features
| Feature | Design Value |
|---|---|
| Quad I/O Interface (SQI) | Four multiplexed I/O lines (SIO[3:0]) deliver 4× bandwidth vs. standard SPI at same clock frequency - reduces pin count and PCB routing complexity. |
| EUI-48/EUI-64 Identifier | Globally unique factory-programmed identifiers stored in SFDP table - enables zero-touch device provisioning and secure network onboarding. |
| Write-Suspend Capability | Allows suspension of active program/erase operations to service urgent read requests - critical for deterministic real-time firmware execution. |
| Flexible Block Protection | Per-block software write-lock (with OTP lock-down) and top/bottom parameter block read-lock - enforces secure boot partitioning and firmware integrity. |
| Security ID (SecID) | 2 KByte OTP area: 64-bit factory-unique ID + user-programmable segment, lockable via LSID command - supports cryptographic key binding and anti-cloning. |
Applications

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-only (no SQI), 133 MHz max, no factory EUI or OTP SecID, 10K-cycle endurance. | Lacks SQI bandwidth and hardware-secured identity; suitable only where SPI suffices and identity is managed externally. | Select when cost sensitivity outweighs need for quad I/O speed or embedded device identity. |
| Cypress S25FL116K0XMFI011 | 16 Mbit SPI/x2, 104 MHz, no EUI-48/EUI-64, no OTP SecID, 100K-cycle endurance, supports XIP but no write-suspend. | Missing EUI identifiers and suspend capability; offers XIP support not present in SST26VF016BEUI-104I/SN. | Choose when execute-in-place operation is required and identity/authentication is handled off-chip. |
Compared with W25Q16JVSNIQ and S25FL116K0XMFI011, the SST26VF016BEUI-104I/SN uniquely integrates factory-assigned EUI-48/EUI-64, OTP Security ID, and write-suspend - enabling secure, real-time firmware updates without external identity management or timing arbitration logic.

FAQ
What is the maximum operating frequency of the SST26VF016BEUI-104I/SN and under what voltage conditions?
The SST26VF016BEUI-104I/SN supports up to 104 MHz maximum clock frequency when powered at 2.7–3.6 V, and up to 80 MHz at 2.3–3.6 V. These frequencies apply to both SPI and SQI read operations, with SQI achieving up to 416 MB/s effective throughput due to 4-bit parallel data transfer. The device automatically adapts timing based on applied VDD.
Does the SST26VF016BEUI-104I/SN support both SPI and SQI interfaces, and how is mode switching performed?
Yes, the SST26VF016BEUI-104I/SN supports both SPI (x1/x2) and SQI (x4) modes. It powers up in SPI mode by default. To enable SQI mode, the host must first set the IOC bit (Bit 1 of Configuration Register) to '1', then issue the EQIO (38H) command. The IOC bit must be set before executing any SQI-specific instructions like SQOR or SQIOR.
How is the EUI-48 and EUI-64 identifier accessed in the SST26VF016BEUI-104I/SN?
The EUI-48 and EUI-64 identifiers in the SST26VF016BEUI-104I/SN are factory-programmed into the Serial Flash Discoverable Parameters (SFDP) table and accessed using the SFDP read instruction (5AH) with address 000000h. These identifiers are read-only, globally unique, and used for device identification in networked and secure boot applications.
What protection mechanisms does the SST26VF016BEUI-104I/SN provide against unauthorized writes?
The SST26VF016BEUI-104I/SN provides three-tiered write protection: (1) software-controlled Block-Protection Register (BPR) with per-block write/read lock; (2) volatile Lock-Down Block-Protection Register (LBPR) disabling further BPR changes until power cycle; and (3) non-volatile nVWLDR enabling permanent OTP lock-down of individual blocks. Hardware WP# pin support is also available when configured.
Is the SST26VF016BEUI-104I/SN qualified for automotive applications?
Yes, the SST26VF016BEUI-104I/SN is AEC-Q100 qualified for automotive applications. It operates across the industrial temperature range (–40°C to +85°C), meets automotive reliability standards, and is suitable for use in diagnostic modules, body control units, and infotainment subsystems where certified component qualification is required.
