Product details
Overview
SST26WF016BA-104I/CS from Microchip Technology is a 1.8V, 16 Mbit Serial Quad I/O (SQI) flash memory IC designed for embedded firmware storage and code execution in space-constrained systems. It supports x1/x2/x4 SPI and SQI protocols, delivers 104 MHz max clock frequency, features uniform 4 KByte sectors, and operates across -40°C to +85°C industrial temperature range.
For engineers reviewing the SST26WF016BA-104I/CS datasheet, SST26WF016BA-104I/CS pinout, SST26WF016BA-104I/CS application, or SST26WF016BA-104I/CS equivalent, key selection considerations include its dual-mode interface compatibility (SPI/SQI), hardware write-protection disable-by-default configuration, deep power-down current of 2.5 μA, and factory OTP Security ID with 64-bit unique identifier.
Technical Context
The SST26WF016BA-104I/CS implements a six-wire, 4-bit multiplexed I/O interface supporting both Mode 0 and Mode 3 SPI timing, with SIO[3:0] pins configurable for quad I/O operation via EQIO command. Its SuperFlash® technology enables single-supply 1.65–1.95 V operation and achieves 18 ms typical sector erase time.
Unlike the SST26WF016B variant, the SST26WF016BA-104I/CS ships with IOC=1 at power-up-disabling WP# and HOLD# pins by default and enabling SIO2/SIO3 for quad mode-while retaining full command-set compatibility with legacy SPI flash devices and supporting burst reads with wrap-around in 8/16/32/64-byte increments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (2 MByte), organized as thirty 64 KByte blocks + two 32 KByte + eight 8 KByte parameter blocks |
| Interface Protocol | Supports SPI (x1/x2/x4) and SQI modes; IOC=1 at power-up enables SIO[3:0] quad I/O by default |
| Max Clock Frequency | 104 MHz - enables high-throughput read access up to 416 MB/s in quad mode |
| Supply Voltage | 1.65–1.95 V - single low-voltage rail simplifies power design for battery-powered or ultra-low-power systems |

Pinout & Package
Package: 8-contact WDFN (6 mm × 5 mm), RoHS-compliant, moisture-sensitive level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CE# | Chip Enable | Active-low selection signal; must remain low during full command sequence including address/data transfer |
| SIO0 (SI) | Serial Data Input | Primary input for commands, addresses, and data in SPI mode; multiplexed I/O in SQI mode |
| SIO1 (SO) | Serial Data Output | Primary output for read data in SPI mode; multiplexed I/O in SQI mode |
| SIO2 (WP#) | Write Protect / Quad I/O | Hardware write-protect input in SPI mode; functions as SIO2 in SQI mode (IOC=1 default) |
| SIO3 (HOLD#) | Hold / Quad I/O | Pauses serial communication in SPI mode; functions as SIO3 in SQI mode (IOC=1 default) |
| SCK | Serial Clock | Timing reference; data latched on rising edge (input), shifted out on falling edge (output) |
| VDD | Power Supply | 1.65–1.95 V supply rail; decoupling capacitor required per layout guidelines |
| VSS | Ground | Reference return path; requires low-impedance connection to system ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Quad I/O Interface (SQI) | Enables 4× throughput vs. standard SPI at same clock rate; reduces pin count and PCB routing complexity |
| Flexible Erase Architecture | Uniform 4 KByte sectors plus overlay blocks (8/32/64 KByte) allow granular firmware partitioning and OTA update management |
| Write-Suspend Capability | Allows interruption of active program/erase to service higher-priority read requests-critical for real-time boot loaders |
| Security ID with OTP | 2 KByte dedicated area: 64-bit factory-unique ID + user-programmable segment, lockable via LSID command |
| Hardware Write Protection Disable-by-Default | IOC=1 at power-up disables WP# and HOLD# pins, eliminating external pull-up requirements in new designs |

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 W25Q16JW-IQ | 16 Mbit, 1.7–2.0 V supply, 133 MHz max clock, no built-in Security ID, different pinout (SOIC/WSON only) | Lacks OTP Security ID and flexible overlay block structure; supports octal DTR but not SQI protocol | Select when higher clock speed is prioritized over security features and quad I/O interface simplicity |
| Cypress S25FL116K0XMFI001 | 16 Mbit, 2.7–3.6 V supply, 85 MHz max clock, no deep power-down mode, different command set | Requires higher voltage rail; lacks write-suspend and burst-wrap capabilities; no factory-unique ID | Select for legacy 3.3 V systems where voltage compatibility outweighs low-power and advanced feature requirements |

FAQ
What is the default I/O configuration of SST26WF016BA-104I/CS at power-up?
The SST26WF016BA-104I/CS powers up with IOC=1, disabling the WP# and HOLD# pins and enabling SIO2/SIO3 for quad I/O operation. This differs from the SST26WF016B variant, which defaults to IOC=0. The configuration register bit is non-volatile, so the setting persists across power cycles unless explicitly rewritten.
Does SST26WF016BA-104I/CS support execute-in-place (XIP) operation?
Yes, SST26WF016BA-104I/CS supports XIP via high-speed continuous linear burst reads and wrap-around burst modes (8/16/32/64 bytes). Its 104 MHz max clock and quad I/O capability enable efficient instruction fetch directly from flash, reducing reliance on external RAM for code execution in MCU-based systems.
How does the Security ID feature work in SST26WF016BA-104I/CS?
The SST26WF016BA-104I/CS includes a 2 KByte Security ID area: 64 bits factory-programmed with a unique identifier (read-only), plus a user-programmable segment. The LSID command permanently locks the entire area, preventing further writes. Once locked, the SEC bit in the status register remains '1' indefinitely, ensuring immutable device identity for secure boot chains.
What is the difference between SST26WF016BA-104I/CS and SST26WF016B-104I/CS?
The core difference lies in power-up configuration: SST26WF016BA-104I/CS defaults to IOC=1 (WP#/HOLD# disabled, SIO2/SIO3 enabled), while SST26WF016B-104I/CS defaults to IOC=0. Both share identical density, voltage, timing, and feature set-but SST26WF016BA-104I/CS simplifies new designs by eliminating external WP#/HOLD# pull-ups.
Can SST26WF016BA-104I/CS be used in place of standard SPI flash in existing designs?
Yes, SST26WF016BA-104I/CS maintains full command-set compatibility with traditional SPI flash (e.g., "25" series) and operates in SPI mode by default. Pin-compatible with 8-lead SOIC, WDFN, and XFBGA packages, it requires only firmware-level enablement of SQI mode (via EQIO command) to unlock quad-speed benefits-no PCB changes needed.
