Product details
Overview
SST26VF016BT-104V/SM from Microchip Technology is a 16 Mbit Serial Quad I/O™ (SQI™) flash memory IC supporting 2.7–3.6 V operation, 104 MHz max clock frequency, 4 KByte uniform sector erase, and flexible software/hardware write protection. It serves as non-volatile program/data storage in microcontroller boot loaders and firmware update modules.
For engineers reviewing the SST26VF016BT-104V/SM datasheet, SST26VF016BT-104V/SM pinout, SST26VF016BT-104V/SM application, or SST26VF016BT-104V/SM equivalent, key selection criteria include SQI/x4 SPI interface compatibility, industrial temperature range (–40°C to +85°C), WDFN-8 (6 mm × 5 mm) package, 100,000 program/erase endurance, and OTP Security ID support.
Technical Context
The SST26VF016BT-104V/SM implements a six-wire, 4-bit multiplexed serial interface (SIO[3:0]) with full backward compatibility to standard SPI (Mode 0/3, x1/x2/x4). Its SuperFlash® split-gate CMOS technology enables single-supply 2.7–3.6 V operation and reduces total energy per erase/program cycle versus conventional flash.
It supports burst read modes (continuous, 8/16/32/64-byte wrap), write-suspend for concurrent block access, and dual protection layers: volatile lock-down (LBPR) and one-time-programmable non-volatile lock-down (nVWLDR) for individual 4–64 KByte blocks. The device ships with IOC=0 and WPEN=0 by default, enabling HOLD#/WP# pins in SPI mode.

Applications
| Boot Code Storage | Firmware Over-the-Air (OTA) Updates |
|---|---|
Use Scenario: Storing primary bootloader and application firmware image for ARM Cortex-M or RISC-V microcontrollers during cold start. IC Role / Device Role / Timing Role: Non-volatile code storage with fast linear burst read to feed instruction fetch pipeline. Use Value: 104 MHz SQI interface reduces boot time by ~3× vs. legacy SPI flash; 4 KByte sector granularity allows safe in-field bootloader patching. | Use Scenario: Hosting delta firmware patches in connected IoT gateways requiring secure, atomic update rollback. IC Role / Device Role / Timing Role: Dual-bank update storage with independent block protection to isolate active and staging firmware partitions. Use Value: Write-suspend enables immediate response to network interrupts during erase; OTP Security ID validates patch authenticity pre-execution. |
| Industrial HMI Configuration | Automotive Diagnostic Module |

IC Role / Device Role / Timing Role: Parameter block storage with read-lock capability to prevent unauthorized extraction of sensitive configuration. Use Value: Eight 8 KByte parameter blocks support multi-language UIs; read-lock returns 0x00 on access - cryptographically hides protected content. | Use Scenario: Storing UDS diagnostic routines and vehicle-specific DTC definitions in AEC-Q100 qualified engine control units. IC Role / Device Role / Timing Role: AEC-Q100 Grade 2 (–40°C to +105°C) non-volatile storage for safety-critical diagnostic assets. Use Value: 100,000-cycle endurance ensures 15+ years of reliable reprogramming over vehicle lifetime; deep power-down (DPD) mode cuts standby current to <1 µA. |
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 flash (x1 only); no SQI or quad I/O; 133 MHz max clock; lacks OTP Security ID and nVWLDR | Lower-cost SPI-only designs where bandwidth and advanced security are not required | Select when board layout uses standard SPI routing and firmware update security is handled externally |
| Cypress S25FL116K0XMFI001 | 16 Mbit FL-S family; supports octal DTR mode; includes hardware reset (RST#) pin; no OTP Security ID; different status register bit mapping | High-reliability industrial systems needing deterministic reset behavior and higher-density migration path | Select when future scalability to 32/64 Mbit FL-S devices is planned and external reset coordination is preferred |
Compared with SST26VF016BT-104V/SM, W25Q16JVSIM offers higher clock speed but sacrifices SQI bandwidth and integrated security; S25FL116K0XMFI001 adds octal DTR and reset pin at the cost of larger footprint and no factory-unique ID - making SST26VF016BT-104V/SM optimal for compact, secure, high-throughput embedded boot storage.

FAQ
What voltage range does the SST26VF016BT-104V/SM support for reliable operation?
The SST26VF016BT-104V/SM operates reliably across 2.7–3.6 V. At this full range, it achieves its rated 104 MHz maximum clock frequency. Operation down to 2.3 V is supported only for reduced-speed applications (max 80 MHz), but the SST26VF016BT-104V/SM is specified and tested for full functionality-including all erase, program, and protection features-within the 2.7–3.6 V window.
Does the SST26VF016BT-104V/SM support true quad I/O mode out of reset?
No. The SST26VF016BT-104V/SM powers up in standard SPI mode (x1) with SI/SO pins active. To enable quad I/O, the host must first issue the EQIO (0x38) command and set the IOC bit in the Configuration Register. Only then do SIO[3:0] become fully bidirectional for high-speed SQI transfers. This design ensures backward compatibility with legacy SPI controllers while enabling bandwidth scaling when needed.
How does the Security ID feature of the SST26VF016BT-104V/SM work in practice?
The SST26VF016BT-104V/SM provides a 2 KByte Security ID space: the first 64 bits are factory-programmed with a unique, unchangeable identifier; the remaining 2040 bytes are user-programmable. Once the LSID (Lockout Security ID) command is executed, the entire space becomes read-only. This enables secure device binding, license enforcement, or cryptographic key storage - all verified by reading the immutable factory ID before accepting user data.
Can the SST26VF016BT-104V/SM be used in automotive applications?
Yes. The SST26VF016BT-104V/SM is AEC-Q100 qualified (Grade 2: –40°C to +105°C), making it suitable for under-hood and cabin automotive applications including engine control units, body control modules, and ADAS diagnostic interfaces. Its 100,000-cycle endurance and >100-year data retention meet stringent automotive reliability requirements, and the WDFN-8 package supports automated optical inspection in high-volume manufacturing.
What is the purpose of the nVWLDR register in the SST26VF016BT-104V/SM?
The non-Volatile Write-Lock Lock-Down Register (nVWLDR) in the SST26VF016BT-104V/SM provides irreversible, one-time programmable protection for individual memory blocks. Writing '1' to any nVWLDR bit permanently disables future changes to the corresponding write-lock bit in the Block-Protection Register - even after power cycles. This is used to harden critical firmware sections (e.g., bootloader) against accidental or malicious modification in deployed systems.
