Product details
Overview
SST26WF016B-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 104 MHz max clock frequency, x1/x2/x4 SPI and SQI protocols, 4 KByte uniform sectors, and operates across -40°C to +85°C industrial temperature range.
For engineers reviewing the SST26WF016B-104I/CS datasheet, SST26WF016B-104I/CS pinout, SST26WF016B-104I/CS application, or SST26WF016B-104I/CS equivalent, key selection criteria include single-supply 1.65–1.95V operation, write-suspend capability, OTP Security ID, hardware WP#/HOLD# support, and WDFN-8 (6×5 mm) package compatibility with legacy SOIC footprints.
Technical Context
The SST26WF016B-104I/CS implements SST's SuperFlash® technology with split-gate cells and thick-oxide tunneling, enabling 100,000 program/erase cycles and >100-year data retention. Its dual-mode interface defaults to SPI after power-on reset and transitions to 4-bit SQI mode via EQIO command, delivering up to 4× throughput versus standard SPI at identical clock rates.
Memory organization includes eight 8 KByte parameter blocks, two 32 KByte overlay blocks, thirty 64 KByte overlay blocks, and uniform 4 KByte erasable sectors. Protection is implemented via volatile Block-Protection Register (BPR), non-volatile Write-Lock Lock-Down Register (nVWLDR), and hardware WP#/HOLD# pins enabled by IOC=0 configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (2 MByte) - sufficient for boot code, firmware images, and configuration data in microcontroller-based systems. |
| Supply Voltage | 1.65–1.95 V - enables direct interfacing with 1.8V logic domains without level shifting. |
| Max Clock Frequency | 104 MHz - supports high-speed read bursts up to 416 MB/s in quad I/O mode. |
| Endurance & Retention | 100,000 cycles / >100 years - suitable for field-upgradable firmware with infrequent reprogramming. |
| Erase Granularity | 4 KByte sectors, 8/32/64 KByte blocks - allows fine-grained updates without full chip erase. |
| Security Features | 2 KByte OTP Security ID with factory-programmed 64-bit ID and user-programmable area - enables device authentication and secure boot binding. |
| Power Consumption | 15 mA active read @ 104 MHz; 10 μA standby; 2.5 μA deep power-down - reduces system-level quiescent current in battery-powered applications. |
Pinout & Package
Package: 8-contact WDFN (6 mm × 5 mm), RoHS-compliant, moisture sensitivity level (MSL) 3 per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CE# | Chip Enable | Active-low enable signal; must remain low during entire command sequence including address/data transfer. |
| SIO0/SI | Serial Data Input | Primary input for commands, addresses, and data in SPI mode; multiplexed as bidirectional SIO[0] in SQI mode. |
| SIO1/SO | Serial Data Output | Primary output for read data in SPI mode; multiplexed as bidirectional SIO[1] in SQI mode. |
| WP#/SIO2 | Write Protect / Quad I/O | Hardware write-protection control for BPR/Config registers when IOC=0 and WPEN=1; serves as SIO[2] in SQI mode. |
| HOLD#/SIO3 | Hold / Quad I/O | Pauses ongoing SPI transfers without resetting internal state; functions as SIO[3] in SQI mode when IOC=1. |
| SCK | Serial Clock | Timing reference; rising edge latches inputs, falling edge shifts out outputs; supports Mode 0 and Mode 3 polarity/phase configurations. |
| VDD | Power Supply | 1.65–1.95 V supply input; decoupling capacitor required per datasheet layout guidelines. |
| VSS | Ground | Reference ground for all I/O and core circuitry; requires low-impedance connection to system GND plane. |
Key Features
| Feature | Design Value |
|---|---|
| Quad I/O Interface (SQI) | Enables 4-bit multiplexed data transfer, quadrupling bandwidth over standard SPI at same clock frequency without increasing pin count. |
| Write-Suspend Capability | Allows interruption of active Program or Erase operations to service higher-priority reads or writes elsewhere in memory. |
| Flexible Block Protection | Per-block software lock-down (volatile and non-volatile), plus hardware WP# pin, enabling layered security for bootloader, calibration, and user data partitions. |
| OTP Security ID | 2 KByte dedicated space with factory-programmed unique 64-bit ID and user-writable segment - supports cryptographic key binding and anti-cloning. |
| Low-Power Deep Power-Down | 2.5 μA typical current draw with fast wake-up (<10 μs), ideal for always-on IoT nodes requiring ultra-low standby consumption. |

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 | 1.8V 16 Mbit, 133 MHz max, DTR support, no SQI; uses standard SPI quad I/O (QPI) instead of Microchip's SQI protocol. | Lacks native SQI interface and Security ID OTP space; supports octal DTR mode not available on SST26WF016B-104I/CS. | Select when higher clock rate or DTR mode is prioritized over SQI compatibility and embedded security features. |
| Cypress S25FL116K0XMFI011 | 1.8V 16 Mbit, 104 MHz, supports both SPI and QPI; includes 128-byte OTP array but no 2 KByte Security ID partition. | No dedicated 2 KByte OTP Security ID; different command set for protection and suspend/resume operations. | Choose when migrating from Cypress portfolio or when integrated debug trace buffer support is required. |
Compared with Winbond W25Q16JW-IQ and Cypress S25FL116K0XMFI011, the SST26WF016B-104I/CS uniquely combines SQI protocol, 2 KByte OTP Security ID, and write-suspend functionality in a single 1.8V serial flash, making it optimal for secure, high-throughput embedded boot applications where pin count and power efficiency are constrained.

FAQ
What is the default I/O configuration for SST26WF016B-104I/CS at power-up?
The SST26WF016B-104I/CS ships with IOC bit = 0 at power-up, enabling WP# and HOLD# pins for hardware write protection and hold functionality in SPI mode. This differs from the SST26WF016BA variant, which defaults to IOC = 1. The IOC bit can be modified via the Configuration Register, but doing so disables WP#/HOLD# and enables SIO2/SIO3 for quad I/O operation.
Does SST26WF016B-104I/CS support true pin-to-pin compatibility with standard SPI flash devices?
Yes - the SST26WF016B-104I/CS maintains full command-set compatibility with traditional SPI flash (e.g., 25-series), including standard Read, Page Program, and Sector Erase instructions. Its 8-pin WDFN package matches industry-standard SOIC-8 and XFBGA footprints, enabling drop-in replacement in existing designs without PCB changes.
How does the Security ID feature of SST26WF016B-104I/CS enhance system security?
The SST26WF016B-104I/CS includes a dedicated 2 KByte Security ID space with a factory-programmed 64-bit unique identifier and user-programmable segment. Once locked via LSID command, this area becomes immutable, enabling cryptographic binding of firmware to hardware and preventing cloning or unauthorized firmware loading in certified medical or industrial systems.
What are the timing implications of using Write-Suspend with SST26WF016B-104I/CS?
When SST26WF016B-104I/CS receives a Write-Suspend command during an active Program or Erase operation, it halts the internal process within 5 μs and enters a known ready state. The suspended operation retains its context and resumes automatically upon receipt of WRRE command, with total suspend/resume overhead adding ≤15 μs - negligible compared to typical erase times (18–50 ms).
Can SST26WF016B-104I/CS operate reliably in extended temperature environments beyond -40°C to +85°C?
No - the SST26WF016B-104I/CS is qualified only for industrial temperature range (-40°C to +85°C) as specified in DS20005013D. Operation outside this range may result in undefined behavior, reduced endurance, or data retention failure. For extended temperature applications, consult Microchip's automotive-grade variants or alternative qualified flash families.
