Product details
Overview
SST26VF016B-104V/SM from Microchip Technology is a 16 Mbit Serial Quad I/O™ (SQI™) flash memory IC designed for high-speed, low-power embedded code storage and data logging. It operates at 104 MHz (2.7–3.6 V), supports x1/x2/x4 SPI and SQI protocols, features uniform 4 KByte sectors, and delivers 100,000 program/erase cycles with >100-year data retention - deployed in automotive instrument clusters, industrial PLC firmware storage, and IoT edge node boot memory.
For engineers reviewing the SST26VF016B-104V/SM datasheet, SST26VF016B-104V/SM pinout, SST26VF016B-104V/SM application, or SST26VF016B-104V/SM equivalent, key selection considerations include its dual-mode interface (SPI/SQI), flexible block protection architecture, 8-contact WDFN package compatibility, and AEC-Q100 qualification for automotive use.
Technical Context
The SST26VF016B-104V/SM implements a six-wire, 4-bit multiplexed I/O interface (SIO[3:0]) supporting both Mode 0 and Mode 3 SPI timing, enabling up to 4× throughput versus standard SPI at identical clock rates. Its SuperFlash® split-gate cell technology enables single-supply operation (2.3–3.6 V), fast erase (18 ms sector, 35 ms chip), and page-program capability (256 bytes/page).
It integrates configurable hardware write protection (WP# pin + WPEN/IOC bits), software-controlled block locking (48-bit Block-Protection Register), non-volatile lock-down (nVWLDR), and a 2 KByte OTP Security ID with factory-programmed 64-bit unique identifier - all accessible via standardized command set including RDSR, WRSR, RBPR, WBPR, PSID, and LSID.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (2 MByte) organized as thirty 64 KByte blocks, two 32 KByte blocks, eight 8 KByte parameter blocks, and uniform 4 KByte sectors. |
| Max Clock Frequency | 104 MHz at 2.7–3.6 V supply; enables 416 MB/s effective quad-I/O read bandwidth in SQI mode. |
| Erase Performance | Sector/Block Erase: 18 ms typical; Chip Erase: 35 ms typical - reduces firmware update latency in field-deployed devices. |
| Endurance & Retention | 100,000 program/erase cycles minimum; >100 years data retention - suitable for infrequently updated but mission-critical configuration storage. |
| Supply Voltage Range | 2.3–3.6 V (full functionality); 2.7–3.6 V (104 MHz operation) - compatible with modern low-voltage microcontroller I/O domains. |
| Temperature Range | Industrial Plus: –40°C to +105°C - validated for under-hood automotive and high-ambient industrial environments. |
| AEC-Q100 Grade | Qualified per AEC-Q100 Rev G, Grade 3 - meets automotive reliability and stress-test requirements for functional safety systems. |
Pinout & Package
Package: 8-contact WDFN (6 mm × 5 mm), RoHS-compliant, moisture sensitivity level (MSL) 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CE# | Chip Enable | Active-low enable signal; must remain low throughout command sequence - controls device selection in multi-flash bus configurations. |
| SIO0–SIO3 | Quad I/O Data Lines | Multiplexed bidirectional serial data lines; configured for SQI mode via EQIO command - enable 4-bit parallel data transfer without additional pins. |
| SCK | Serial Clock | Input clock synchronized to rising edge for input latching and falling edge for output shifting - supports Mode 0 and Mode 3 timing for legacy SPI compatibility. |
| WP# | Hardware Write Protect | Active-low pin that, when enabled (WPEN=1, IOC=0), prevents writes to Block-Protection and Configuration registers - provides board-level security during manufacturing or field service. |
| HOLD# | Communication Hold | Pauses active SPI sequences without resetting internal state; only functional in SPI single/dual mode - allows host CPU to service higher-priority interrupts mid-transfer. |
| VDD | Power Supply | Primary 2.3–3.6 V supply rail; decoupling capacitor required near pin to suppress switching noise during high-frequency reads/writes. |
| VSS | Ground | Reference ground for all I/O and core logic; must be connected to low-impedance system ground plane to ensure signal integrity. |
Key Features
| Feature | Design Value |
|---|---|
| Serial Quad I/O (SQI) Interface | Enables 4× faster read throughput vs. standard SPI at same clock frequency using only 6 pins - reduces PCB layer count and routing complexity in space-constrained designs. |
| Flexible Block Protection | Software-configurable per-block write-lock (48-bit BPR) plus permanent non-volatile lock-down (nVWLDR) - secures bootloader, calibration data, and cryptographic keys against unauthorized modification. |
| Security ID with OTP Segment | 2 KByte dedicated area: 64-bit factory-unique ID + user-programmable region - supports device authentication, secure boot binding, and anti-cloning in certified automotive and industrial systems. |
| Write-Suspend Capability | Allows suspension of ongoing Program or Erase operations to service time-critical reads - eliminates firmware stalls during real-time data acquisition or control loops. |
| Deep Power-Down Mode | Reduces standby current to 1 µA (typical) - extends battery life in always-on sensor nodes and portable diagnostic tools. |

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 W25Q16JW | 16 Mbit, 133 MHz max, DTR support, no SQI mode; 1.65–3.6 V supply; lacks OTP Security ID and nVWLDR. | Better suited for cost-sensitive consumer electronics where ultra-fast dual-transfer-rate reads matter more than automotive-grade security. | Select W25Q16JW if SQI interface and AEC-Q100 qualification are unnecessary and higher clock speed is prioritized. |
| Cypress S25FL116K | 16 Mbit, 104 MHz max, supports XIP and wrap-around burst; no OTP Security ID; different block protection granularity (64 KByte only). | Optimized for execute-in-place (XIP) code execution in microcontrollers with QSPI peripherals - less emphasis on individual parameter block locking. | Choose S25FL116K when direct code execution from flash is required and advanced security features are secondary. |
Compared with W25Q16JW and S25FL116K, the SST26VF016B-104V/SM uniquely combines AEC-Q100 qualification, integrated OTP Security ID, and granular 4 KByte/8 KByte/32 KByte/64 KByte block protection - making it the only option among the three qualified for safety-critical automotive boot storage with cryptographic binding.

FAQ
What is the maximum operating frequency of the SST26VF016B-104V/SM?
The SST26VF016B-104V/SM 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. This rating applies to both SPI and SQI modes, with SQI delivering up to 416 MB/s effective read bandwidth due to 4-bit parallel data transfer. The "104" in the part number explicitly denotes this 104 MHz capability under nominal voltage conditions.
Does the SST26VF016B-104V/SM support both SPI and SQI interfaces?
Yes, the SST26VF016B-104V/SM supports full backward-compatible SPI operation (x1/x2/x4 modes, Mode 0/Mode 3) and native SQI protocol using SIO[3:0] pins. After power-on reset, it defaults to SPI mode; SQI mode is enabled via the EQIO command. The IOC bit in the Configuration register must be set to '1' before issuing SQI-specific commands like SQOR or SQIOR.
What package type is used for the SST26VF016B-104V/SM?
The SST26VF016B-104V/SM is packaged in an 8-contact WDFN (6 mm × 5 mm) with exposed pad, compliant with RoHS and MSL Level 3. This compact, thermally efficient package supports reflow soldering and is optimized for high-density PCB layouts in automotive and industrial modules where board space is constrained.
Is the SST26VF016B-104V/SM qualified for automotive applications?
Yes, the SST26VF016B-104V/SM is AEC-Q100 qualified (Grade 3: –40°C to +105°C), making it suitable for automotive applications including instrument clusters, body control modules, and ADAS subsystems. Its qualification covers stress testing for temperature cycling, humidity bias, and ESD - ensuring reliability in harsh vehicular environments.
How does the Security ID feature work in the SST26VF016B-104V/SM?
The SST26VF016B-104V/SM includes a 2 KByte Security ID area comprising a factory-programmed 64-bit unique identifier (read-only) and a user-programmable segment. Users can write to the latter via the PSID command and permanently lock it using LSID. Once locked, no further writes are possible - enabling secure device binding, anti-counterfeiting, and cryptographic key anchoring in safety-critical systems.
