Product details
Overview
SST26VF016BT-104V/SN 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) with 4 KByte uniform sectors, 256-byte page programming, and integrated Security ID. It supports SPI x1/x2/x4 and SQI protocols in 8-lead SOIC (3.90 mm) package and is used for firmware storage in industrial microcontroller boot systems.
For engineers reviewing the SST26VF016BT-104V/SN datasheet, SST26VF016BT-104V/SN pinout, SST26VF016BT-104V/SN application, or SST26VF016BT-104V/SN equivalent, key selection criteria include quad-I/O burst read performance, individual block write protection with OTP lock-down, 100,000-cycle endurance, -40°C to +85°C industrial temperature rating, and AEC-Q100 qualification for automotive use.
Technical Context
This device implements Microchip's SuperFlash® technology with split-gate cells and thick-oxide tunneling injectors, enabling faster erase (18 ms sector, 35 ms chip) and lower active current (15 mA @ 104 MHz) than conventional NOR flash. Its dual-mode interface supports legacy SPI (Mode 0/3) and high-speed SQI with four multiplexed I/Os (SIO[3:0]), delivering up to 4× throughput at same clock frequency.
The internal architecture includes a 48-bit Block-Protection Register (BPR), non-volatile Write-Lock Lock-Down Register (nVWLDR), and 2 KByte Security ID space with factory-programmed 64-bit unique identifier. Protection logic enforces hardware WP#/HOLD# pin functions only in SPI mode, while SQI mode disables those pins and enables full quad I/O operation via EQIO command.

Pinout & Package
Package: 8-lead SOIC (3.90 mm width), RoHS-compliant, surface-mount.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CE# | Chip Enable | Active-low chip select; must remain low throughout command sequence to prevent premature termination |
| SO/SIO1 | Serial Output / Quad I/O 1 | Default SPI output pin; reconfigured as bidirectional SIO1 in SQI mode after EQIO command |
| WP#/SIO2 | Write Protect Input / Quad I/O 2 | Hardware write-protection enable in SPI mode; becomes SIO2 in SQI mode when IOC=1 |
| VSS | Ground | Reference return path for all digital and analog circuitry; requires low-impedance PCB connection |
| VDD | Power Supply | 2.3–3.6 V core supply; decoupling capacitor (0.1 µF) required near pin for noise suppression |
| HOLD#/SIO3 | Hold Input / Quad I/O 3 | Pauses ongoing SPI transfers without resetting state; disabled in SQI mode and repurposed as SIO3 |
| SCK | Serial Clock | Timing reference for all serial operations; rising edge latches input, falling edge shifts out data |

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, 100K endurance, same SOIC-8 package | Lacks quad I/O burst and Security ID; suitable where SPI bandwidth suffices and security is handled externally | Select when cost sensitivity outweighs need for SQI speed or embedded UID |
| Cypress S25FL116K0XMFI011 | 16 Mbit, 85 MHz max, supports XIP with prefetch buffer, no OTP Security ID, same SOIC-8 | Optimized for execute-in-place (XIP) with cache line fetch; lacks permanent lock-down and factory UID | Prefer for MCU code execution directly from flash where latency predictability matters more than security binding |
Compared with W25Q16JVSNIQ and S25FL116K0XMFI011, SST26VF016BT-104V/SN uniquely combines SQI bandwidth, on-chip Security ID with factory UID, and permanent block lock-down - making it optimal for secure, high-throughput firmware storage where tamper resistance and fast boot are design-critical.

FAQ
What is the maximum operating frequency of SST26VF016BT-104V/SN and under what voltage conditions?
The SST26VF016BT-104V/SN supports a maximum clock frequency of 104 MHz when operated within the 2.7–3.6 V supply range. At the wider 2.3–3.6 V range, the maximum frequency is reduced to 80 MHz. This voltage-dependent specification is defined in the official Microchip datasheet DS20005262F and applies to both SPI and SQI modes. The "104" in the part number explicitly denotes the 104 MHz rating at 2.7–3.6 V.
Does SST26VF016BT-104V/SN support true quad I/O operation, and how is it enabled?
Yes, SST26VF016BT-104V/SN supports true quad I/O (SQI) operation using all four SIO[3:0] pins for simultaneous bidirectional data transfer. It is enabled by first setting the IOC bit (bit 1) in the Configuration Register to '1', then issuing the Enable Quad I/O (EQIO, 0x38) command. Once configured, commands like SQOR (0x6B) and SQIOR (0xEB) become active. The device defaults to SPI mode at power-up for backward compatibility.
What package type does SST26VF016BT-104V/SN use, and is it RoHS compliant?
SST26VF016BT-104V/SN uses an 8-lead SOIC package with 3.90 mm body width, as confirmed by Microchip's official documentation and package drawings in DS20005262F. All variants of the SST26VF016B family, including SST26VF016BT-104V/SN, are RoHS compliant and meet lead-free soldering requirements per JEDEC J-STD-020.
How does the Security ID feature work in SST26VF016BT-104V/SN, and can it be modified?
The SST26VF016BT-104V/SN includes a 2 KByte Security ID (Sec ID) space divided into a factory-programmed 64-bit unique identifier (immutable) and a user-programmable area. Users can write to the user area via the Program Security ID (PSID, 0xA5) command and permanently lock the entire Sec ID space using the Lockout Security ID (LSID, 0x85) command. Once locked, no further writes-including erasure-are possible to either segment.
Is SST26VF016BT-104V/SN qualified for automotive applications, and what standard does it meet?
Yes, SST26VF016BT-104V/SN is AEC-Q100 qualified for automotive applications, as explicitly stated in the Microchip datasheet DS20005262F. It meets Grade 3 (-40°C to +85°C) and optional Grade 2 (-40°C to +105°C) temperature requirements, supporting use in engine control units, body electronics, and infotainment systems where reliability under thermal stress is mandatory.
