Product details
Overview
SST26VF016BT-104I/SM from Microchip Technology is a 16 Mbit Serial Quad I/O™ (SQI™) flash memory IC operating at up to 104 MHz (2.7–3.6 V), supporting x1/x2/x4 SPI and full SQI protocols, with 4 KByte uniform sectors, 100,000 program/erase cycles, and industrial temperature range (–40°C to +85°C). It serves as non-volatile code/data storage in microcontroller boot loaders and firmware update modules.
For engineers reviewing the SST26VF016BT-104I/SM datasheet, SST26VF016BT-104I/SM pinout, SST26VF016BT-104I/SM application, or SST26VF016BT-104I/SM equivalent, key selection considerations include quad-I/O burst read performance, flexible block protection architecture, hardware write-protection pin behavior, and compatibility with both legacy SPI and high-speed SQI host controllers.
Technical Context
The SST26VF016BT-104I/SM implements a six-wire SQI interface (SCK, CE#, WP#, HOLD#, VDD, VSS, and multiplexed SIO[3:0]) enabling 4-bit bidirectional data transfer, achieving up to 4× throughput versus standard SPI at identical clock frequency. Its SuperFlash® split-gate cell technology enables fast erase (18 ms sector, 35 ms chip) and low active current (15 mA @ 104 MHz).
It supports dual operational modes: default SPI mode (SI/SO pins active) and configurable SQI mode (SIO[3:0] multiplexed), selected via EQIO command and IOC bit. The device integrates a 48-bit Block-Protection Register, non-volatile Write-Lock Lock-Down register (nVWLDR), and 2 KByte OTP Security ID with factory-programmed 64-bit unique identifier.

Pinout & Package
Package: 8-contact WDFN (6 mm × 5 mm), RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Key Features
| Feature | Design Value |

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 W25Q16JWIM | 16 Mbit, 133 MHz Quad SPI, 1.65–3.6 V, no SQI mode, no Security ID OTP | Lacks SQI protocol and factory UID; suitable for cost-sensitive consumer designs without security requirements | Select when maximum clock speed (133 MHz) and ultra-low voltage (1.65 V) are prioritized over secure identity and SQI bandwidth |
| Cypress S25FL116K0XMFI001 | 16 Mbit, 104 MHz Quad SPI, 2.7–3.6 V, HyperBus option, no OTP Security ID | Offers HyperBus interface alternative but omits factory-programmed UID and nVWLDR lock-down | Choose for designs already using Cypress ecosystem tools or requiring HyperBus compatibility; not recommended for secure boot use cases |
Compared with SST26VF016BT-104I/SM, W25Q16JWIM trades SQI bandwidth and secure identity for wider voltage range and higher clock rate, while S25FL116K0XMFI001 substitutes HyperBus flexibility for missing OTP-based device authentication - making SST26VF016BT-104I/SM uniquely suited for secure, high-throughput embedded boot applications.

FAQ
What is the maximum clock frequency supported by SST26VF016BT-104I/SM?
The SST26VF016BT-104I/SM 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. This frequency applies to both SPI and SQI modes, with SQI delivering up to 416 MB/s theoretical throughput due to 4-bit parallel data transfer. The device is rated for industrial temperature (–40°C to +85°C) at these speeds.
Does SST26VF016BT-104I/SM support true Quad I/O mode out of reset?
No - SST26VF016BT-104I/SM powers up in standard SPI mode (SI/SO pins active). To enable Quad I/O mode, the host must first set the IOC bit in the Configuration Register and issue the EQIO (38H) command. Only then do SIO[3:0] become functional as multiplexed bidirectional lines. Failure to configure IOC before issuing SQI commands results in undefined behavior.
How does hardware write protection work on SST26VF016BT-104I/SM?
Hardware write protection on SST26VF016BT-104I/SM requires both WPEN=1 (non-volatile bit) and IOC=0 in the Configuration Register, plus WP# pulled low. When active, it prevents writes only to the Block-Protection and Configuration Registers - not to main memory. The lock-down function (LBPR) supersedes WP#, and once enabled, WP# has no effect until power-cycled.
Can SST26VF016BT-104I/SM be used in automotive applications?
Yes - SST26VF016BT-104I/SM is AEC-Q100 qualified for automotive applications and specified for Industrial temperature (–40°C to +85°C). Its SuperFlash® technology, 100,000-cycle endurance, and >100-year data retention meet stringent reliability requirements for engine control units, ADAS modules, and infotainment systems where firmware integrity is safety-critical.
What is the purpose of the Security ID feature in SST26VF016BT-104I/SM?
The Security ID in SST26VF016BT-104I/SM provides a 2 KByte OTP area containing a factory-programmed, unchangeable 64-bit unique identifier and a user-programmable segment. It supports secure boot binding, device authentication, and cryptographic key storage. Once locked via LSID command, the entire Security ID space becomes read-only and cannot be altered - ensuring persistent identity across product lifetime.
