Product details
Overview
SST26VF016B-104I/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 industrial temperature range (–40°C to +85°C). It supports SPI x1/x2/x4 and SQI protocols in an 8-lead SOIC package and is used for firmware storage in microcontroller boot applications.
For engineers reviewing the SST26VF016B-104I/SN datasheet, SST26VF016B-104I/SN pinout, SST26VF016B-104I/SN application, or SST26VF016B-104I/SN equivalent, key selection criteria include quad-I/O throughput, sector-level write protection granularity, deep power-down current (15 µA), endurance (100,000 cycles), and AEC-Q100 qualification for automotive use.
Technical Context
The SST26VF016B-104I/SN implements a six-wire, 4-bit multiplexed I/O interface (SIO[3:0]) supporting both legacy SPI (Mode 0/3) and high-speed SQI protocols. Its SuperFlash® split-gate cell architecture enables faster erase (18 ms sector, 35 ms chip) and lower energy per operation versus conventional flash.
It integrates dual protection mechanisms: volatile Block-Protection Register (BPR) with 48-bit configuration and non-volatile Write-Lock Lock-Down Register (nVWLDR) with 40 bits, plus hardware WP# and HOLD# pins active only in SPI mode. The device ships with IOC=0 and WPEN=0 by default, enabling SPI compatibility out-of-box.

| VSS | Ground | Reference return path for all digital and analog circuitry; requires low-impedance PCB connection |
| VDD | Power Supply | 2.3–3.6 V supply input; decoupling capacitor (0.1 µF) required within 5 mm of pin |
| HOLD#/SIO3 | Hold Input / Quad I/O 3 | Pauses ongoing SPI transfers without resetting clock state; disabled in SQI mode; tied high if unused |
| SCK | Serial Clock | Master-generated timing signal; data latched on rising edge (input), shifted out on falling edge (output) |

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-only (no SQI), 133 MHz max, 4 KByte sectors, no Security ID or nVWLDR | Lacks quad-I/O speed boost and hardware security features; requires separate secure element for ID binding | Select when cost sensitivity outweighs throughput and security requirements; verify layout supports SOIC-8 footprint match |
| Cypress S25FL116K0XMFI011 | 16 Mbit, 85 MHz max, supports XIP but no SQI; includes 64-bit unique ID but no user-programmable Security ID space | Supports execute-in-place for code execution directly from flash; lacks flexible overlay block structure for firmware partitioning | Prefer for XIP-capable MCUs needing deterministic instruction fetch; confirm compatibility with SST26VF016B-104I/SN's 2.3–3.6 V range and SOIC-8 pinout |
Compared with W25Q16JVSIM and S25FL116K0XMFI011, the SST26VF016B-104I/SN delivers higher sustained read bandwidth via SQI, finer-grained firmware update control through overlay blocks, and integrated security provisioning via programmable 2 KByte Security ID - making it optimal for automotive and secure IoT boot applications where performance, partitioning, and identity binding are jointly critical.

FAQ
What is the maximum clock frequency supported by the SST26VF016B-104I/SN?
The SST26VF016B-104I/SN supports up to 104 MHz in 2.7–3.6 V operation and up to 80 MHz in 2.3–3.6 V operation. This applies to both high-speed SPI Read (0BH) and SQI Read Burst (0CH) commands. Frequency derating to 80 MHz is required for extended temperature (–40°C to +125°C) operation. The 104 MHz rating is validated per DS20005262F, page 1.
Does the SST26VF016B-104I/SN support Quad I/O mode out of the box?
No - the SST26VF016B-104I/SN powers up in standard SPI mode (IOC = 0). To enable Quad I/O, the host must first issue the EQIO command (38H) and set the IOC bit in the Configuration Register. Only then do SIO[3:0] become active as bidirectional quad lines. This ensures backward compatibility with legacy SPI controllers.
How does write protection work on the SST26VF016B-104I/SN?
The SST26VF016B-104I/SN implements three-tiered write protection: (1) hardware via WP# pin (when WPEN=1 and IOC=0), (2) software via 48-bit Block-Protection Register (BPR), and (3) permanent via 40-bit non-Volatile Write-Lock Lock-Down Register (nVWLDR). All protect against program/erase; BPR and nVWLDR also support read-lock for parameter blocks.
What is the purpose of the Security ID feature in the SST26VF016B-104I/SN?
The SST26VF016B-104I/SN includes a 2 KByte Security ID space comprising a factory-programmed 64-bit unique identifier and a user-programmable segment. It supports secure boot authentication via PSID/LSID commands. Once locked with LSID, the entire Security ID space becomes read-only - preventing tampering with cryptographic keys or device identity credentials.
Is the SST26VF016B-104I/SN AEC-Q100 qualified?
Yes - the SST26VF016B-104I/SN is explicitly stated as "Automotive AEC-Q100 Qualified" in the official Microchip datasheet (DS20005262F, page 1). This qualification covers temperature, reliability, and stress testing per AEC-Q100 Rev G, making it suitable for automotive electronic control units and ADAS subsystems.
