Product details
Overview
SST26VF016BAT-104I/SM from Microchip Technology is a 16 Mbit Serial Quad I/O (SQI) flash memory IC operating at 2.3–3.6 V, supporting 104 MHz SPI and 80 MHz SQI interfaces, with uniform 4 KByte sectors, 100,000 write cycles endurance, and industrial temperature range (–40°C to +85°C), deployed in embedded boot code storage and firmware update applications.
For engineers reviewing the SST26VF016BAT-104I/SM datasheet, SST26VF016BAT-104I/SM pinout, SST26VF016BAT-104I/SM application, or SST26VF016BAT-104I/SM equivalent, key selection considerations include quad-I/O burst read performance, flexible block protection granularity (8/32/64 KByte overlay blocks), hardware write-protection via WP# pin, Security ID OTP capability, and WDFN-8 package compatibility with space-constrained PCB layouts.
Technical Context
The SST26VF016BAT-104I/SM implements a six-wire SQI interface (SCK, CE#, WP#, HOLD#, VDD, VSS, plus SIO[3:0] multiplexed I/O) enabling 4-bit data transfers at up to 80 MHz, while retaining full command-set compatibility with legacy SPI (Mode 0/3, x1/x2/x4). Its SuperFlash® split-gate cell architecture delivers faster erase (18 ms sector, 35 ms chip) and lower active current (15 mA @ 104 MHz) versus conventional NOR flash.
It integrates dual protection layers: volatile Block-Protection Register (BPR) with per-block write/read lock control and non-volatile Write-Lock Lock-Down Register (nVWLDR) for permanent OTP-based block lockdown; plus hardware-level WP# and HOLD# pins functional only in SPI mode (IOC = 0), disabled in SQI mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
Package: 8-contact WDFN (6 mm × 5 mm), RoHS-compliant, moisture-sensitive level 3 (MSL3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CE# | Chip Enable | Active-low device select; must remain low throughout command sequence - enables multi-device daisy-chaining on shared SPI bus. |
| SIO[3:0] | Serial I/O (Quad) | Multiplexed bidirectional data lines for command/address/data in SQI mode; default SI/SO in SPI mode - eliminates separate input/output pins, reducing PCB routing complexity. |
| SCK | Serial Clock | Rising-edge latched input for commands/addresses; falling-edge shifted output for data - defines timing boundary for all serial transactions. |
| WP# | Write Protect | Hardware pin disabling writes to Block-Protection and Configuration registers when IOC=0 and WPEN=1 - provides tamper-resistant configuration lockdown independent of firmware state. |
| HOLD# | Hold Control | Pauses ongoing SPI reads without resetting internal state; inactive in SQI mode - allows host CPU to service higher-priority interrupts mid-transfer. |
| VDD | Power Supply | 2.3–3.6 V single supply - simplifies power design by eliminating auxiliary voltage rails required by older 5 V or 2.5 V flash parts. |
| VSS | Ground | Reference return path for all I/O and core logic - requires low-impedance connection to minimize noise coupling during high-speed bursts. |
Key Features
| Feature | Design Value |
|---|---|
| Serial Quad I/O (SQI) Interface | Four multiplexed I/O lines (SIO[3:0]) deliver 4× throughput vs. standard SPI at same clock frequency - cuts firmware load time by up to 75% without changing clock generator or layout. |
| Flexible Erase Architecture | Uniform 4 KByte sectors plus configurable 8/32/64 KByte overlay blocks - supports differential OTA updates where only changed partitions are rewritten, minimizing flash wear. |
| Write-Suspend Capability | WRSU/WRRE commands pause ongoing erase or program to service urgent reads - prevents real-time system stalls during background flash maintenance. |
| Two-Tier Protection Scheme | Volatile BPR + non-volatile nVWLDR with OTP lock-down bits - enables field-deployable security policies that survive power loss and resist runtime reconfiguration attacks. |
| Security ID with Factory OTP | 64-bit unique identifier pre-programmed at wafer test; 2 KByte user area programmable via PSID - provides cryptographic binding between hardware identity and firmware signature verification keys. |

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 W25Q16JVSIQ | 16 Mbit SPI-only (no SQI), 133 MHz max, 4 KByte sectors, no Security ID OTP, different status register bit mapping. | Lacks quad-I/O acceleration and hardware-secured identity - suitable only where SQI bandwidth and cryptographic binding are unnecessary. | Select if cost sensitivity outweighs performance/security needs and existing SPI controller lacks SQI support. |
| Cypress S25FL116K0XMFI011 | 16 Mbit SPI-only, 104 MHz, 4 KByte sectors, no OTP Security ID, supports QPI but not SQI protocol, different pinout (SOIC-8). | Missing SQI interface and factory-programmed ID - limits use in secure boot or high-throughput OTA contexts requiring native quad-burst efficiency. | Choose when migrating from legacy Spansion designs and board layout already accommodates SOIC-8 footprint. |
Compared with W25Q16JVSIQ and S25FL116K0XMFI011, the SST26VF016BAT-104I/SM delivers measurable advantages in boot latency (via SQI burst), field-upgrade resilience (via write-suspend), and hardware-rooted security (via OTP Security ID), making it optimal for next-generation certified embedded systems where performance, safety, and trust are co-prioritized.

FAQ
What is the maximum clock frequency supported by SST26VF016BAT-104I/SM in SQI mode?
The SST26VF016BAT-104I/SM supports up to 80 MHz in SQI mode when operated within the 2.3–3.6 V supply range. This is confirmed in the official Microchip datasheet DS20005262C, Section 1.0 Features. The 104 MHz rating applies only to standard SPI mode under 2.7–3.6 V conditions. SQI mode uses the same physical pins but quadruples effective throughput via 4-bit parallel data transfer per clock cycle.
Does SST26VF016BAT-104I/SM support hardware write protection using the WP# pin?
Yes, SST26VF016BAT-104I/SM supports hardware write protection via the WP# pin, but only when the IOC bit in the Configuration Register is set to '0' and the WPEN bit is set to '1'. In this configuration, pulling WP# low disables writes to the Block-Protection and Configuration registers. The WP# pin is disabled in SQI mode and functions exclusively in SPI single/dual-bit read modes, as specified in DS20005262C Section 4.2.
What package type is used for SST26VF016BAT-104I/SM, and what are its dimensions?
The SST26VF016BAT-104I/SM uses an 8-contact WDFN (WSON) package measuring 6 mm × 5 mm with exposed pad, per Microchip's official package drawing and DS20005262C Figure 2-2. This compact, lead-free RoHS-compliant package supports automated reflow assembly and offers improved thermal performance over SOIC-8 alternatives, making it ideal for space-constrained industrial and automotive PCBs.
Can SST26VF016BAT-104I/SM be used as a direct replacement for standard SPI flash devices?
Yes, SST26VF016BAT-104I/SM is fully command-set compatible with traditional SPI flash (e.g., 25-series), operating in SPI mode by default after power-on reset. It supports Mode 0/3, x1/x2/x4 protocols, and standard instructions like Read (03H), Page Program (02H), and Sector Erase (20H). No hardware changes are needed to migrate from legacy SPI flash, though enabling SQI requires issuing EQIO and setting IOC=1.
What is the purpose and capacity of the Security ID feature in SST26VF016BAT-104I/SM?
The Security ID in SST26VF016BAT-104I/SM is a dedicated 2 KByte area comprising a factory-programmed 64-bit unique identifier (immutable and unerasable) and a user-programmable segment. It supports PSID and LSID commands for writing and permanently locking the user portion. This feature enables hardware-rooted device authentication and secure boot chain binding, as documented in DS20005262C Section 4.3.
