Product details
Overview
SST26WF016BAT-104I/SN from Microchip Technology is a 1.8V, 16 Mbit Serial Quad I/O (SQI) flash memory IC with 104 MHz max clock frequency, 4 KByte uniform sector erase, and 256-byte page programming. It operates from 1.65–1.95 V, supports SPI Mode 0/3 and SQI protocols, and is rated for industrial temperature (−40°C to +85°C). It serves as non-volatile program/data storage in microcontroller boot loaders and firmware update modules.
For engineers reviewing the SST26WF016BAT-104I/SN datasheet, SST26WF016BAT-104I/SN pinout, SST26WF016BAT-104I/SN application, or SST26WF016BAT-104I/SN equivalent, key selection considerations include quad-I/O throughput vs. SPI compatibility, hardware write-protection pin behavior (WP#/HOLD# enabled by default), deep power-down current (2.5 μA), and factory-configured IOC bit state for SQI mode enablement.
Technical Context
The SST26WF016BAT-104I/SN implements Microchip's SuperFlash® technology with split-gate cells, enabling 100,000 program/erase cycles and >100-year data retention. Its six-wire SQI interface uses multiplexed SIO[3:0] pins for command/address/data transfer at up to 104 MHz, delivering quadruple bandwidth versus standard SPI at identical clock rates.
It features dual operational modes: default SPI mode (x1/x2/x4) after power-on reset, and configurable SQI mode via EQIO command. The device includes a 48-bit Block-Protection Register with per-block write/read lock control, volatile lock-down (LBPR), and one-time-programmable non-volatile lock-down (nVWLDR) for permanent protection of 8 KByte, 32 KByte, and 64 KByte blocks.

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 | 1.8 V, 16 Mbit, SPI-only (no SQI), 133 MHz max, 4 KByte sectors, 100K endurance | Lacks quad-I/O interface and SQI protocol; no HOLD#/WP# multiplexing or Security ID | Select when SQI bandwidth is unnecessary and legacy SPI-only host interface is used |
| Cypress S25FL116K0XMFI011 | 1.8 V, 16 Mbit, dual/quad SPI, 104 MHz, 4 KByte sectors, 100K endurance, no Security ID or nVWLDR | Supports QSPI but lacks OTP Security ID, non-volatile lock-down, and SQI-specific burst modes | Select when advanced security features are not required but QSPI timing compatibility is needed |
Compared with SST26WF016BAT-104I/SN, W25Q16JVSNIQ offers higher clock speed but no SQI or security features, while S25FL116K0XMFI011 provides QSPI compatibility yet omits factory-unique ID and permanent block lock-down-making SST26WF016BAT-104I/SN uniquely suited for secure, high-throughput embedded boot applications.

FAQ
What is the default I/O configuration for SST26WF016BAT-104I/SN at power-up?
The SST26WF016BAT-104I/SN ships with the IOC bit set to '0' by default, enabling WP# and HOLD# functionality in SPI mode. This matches the SST26WF016B variant (not SST26WF016BA), meaning both pins are active and functional upon initial power-on without configuration. The IOC bit must be set to '1' before issuing SQI-specific commands like SQOR or SQIOR.
Does SST26WF016BAT-104I/SN support true quad-I/O mode out of the box?
No-SST26WF016BAT-104I/SN powers up in standard SPI mode (x1/x2/x4) with SI/SO pins active. True quad-I/O (SQI) mode requires issuing the EQIO command and setting the IOC bit to '1'. Only then do SIO[3:0] become fully bidirectional for command/address/data transfer. The device does not auto-detect or default to SQI mode.
How does hardware write protection work on SST26WF016BAT-104I/SN?
Hardware write protection on SST26WF016BAT-104I/SN is controlled by the WP# pin in conjunction with the WPEN bit (non-volatile, factory-default '0') and IOC bit (default '0'). When WPEN = 1 and IOC = 0, asserting WP# low disables writes to the Block-Protection and Configuration registers only-not the main memory array. Memory programming remains possible unless software protection is also applied.
Can SST26WF016BAT-104I/SN perform simultaneous read and write operations?
No-SST26WF016BAT-104I/SN does not support concurrent read/write. However, it supports Write-Suspend: an active Program or Erase operation can be paused using the WRSU command, allowing immediate read access to other memory regions. The suspended operation resumes via WRRE, preserving full endurance and timing integrity.
What is the purpose of the Security ID feature in SST26WF016BAT-104I/SN?
The Security ID in SST26WF016BAT-104I/SN provides a 2 KByte dedicated space containing a factory-programmed 64-bit unique identifier and a user-programmable segment. Once locked via the LSID command, the entire Security ID space becomes read-only. This enables device authentication, secure boot binding, and anti-counterfeiting-critical for regulated medical and industrial deployments where traceability is mandatory.
