Product details
Overview
SST26VF016BA-104I/MF 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 read speeds, with uniform 4 KByte sectors, 100,000 program/erase cycles, and industrial temperature range (−40°C to +85°C). It serves as non-volatile code/data storage in microcontroller boot systems, firmware update buffers, and embedded configuration memory.
For engineers reviewing the SST26VF016BA-104I/MF datasheet, SST26VF016BA-104I/MF pinout, SST26VF016BA-104I/MF application, or SST26VF016BA-104I/MF equivalent, key selection considerations include quad-I/O burst performance, flexible block protection granularity (8/32/64 KByte overlay blocks), hardware write-protection via WP# pin, Security ID OTP capability, and WDFN-8 (6 mm × 5 mm) package compatibility with space-constrained PCB layouts.
Technical Context
The SST26VF016BA-104I/MF implements a six-wire SQI interface (SCK, CE#, WP#, HOLD#, and SIO[3:0]) enabling 4-bit multiplexed data transfer, delivering up to 4× bandwidth vs. standard SPI at identical clock frequency. Its SuperFlash® split-gate cell architecture achieves 18 ms sector erase (typ) and 256-byte page programming with software polling of BUSY bit for end-of-write detection.
It supports dual operational modes: default SPI mode (x1/x2/x4) after power-on reset, and configurable SQI mode activated via EQIO command. Mode 0 and Mode 3 clock polarity compatibility ensures interoperability with diverse host controllers, while the Configuration register (IOC, WPEN, BPNV bits) enables runtime reconfiguration of I/O functionality and hardware write-protection behavior.

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 chip select; must remain low throughout command sequence and data transfer - enables multi-device SPI/SQI bus sharing |
| SIO0 (SI) | Serial Data Input (SPI default) | Primary input for commands, addresses, and data in SPI mode; latched on rising SCK edge - used for all write operations and command issuance |
| SIO1 (SO) | Serial Data Output (SPI default) | Primary output for read data in SPI mode; shifted out on falling SCK edge - provides status, ID, and memory content reads |
| SIO2 (WP#) | Write Protect / Quad I/O | In SPI mode: hardware write-protection control (with WPEN/IOC bits); in SQI mode: bidirectional data line - enables secure factory programming lock-down |
| SIO3 (HOLD#) | Hold / Quad I/O | In SPI mode: pauses ongoing serial transaction without resetting state; in SQI mode: bidirectional data line - allows host CPU to service interrupts mid-transfer |
| SCK | Serial Clock | Master-generated timing signal; commands and inputs sampled on rising edge, outputs driven after falling edge - determines maximum interface speed and timing margin |
| VDD | Power Supply | 2.3–3.6 V core and I/O supply - powers internal logic, charge pumps, and I/O buffers; requires local decoupling per layout guidelines |
| VSS | Ground | Reference return path for all internal circuits and I/O signals - must be low-impedance and connected to system ground plane |

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 | Lacks quad-I/O bandwidth and hardware-secured identity; simpler protection model (no nVWLDR) | Choose when SQI performance and device authentication are unnecessary and cost sensitivity dominates. |
| Cypress S25FL116K0XMFI011 | 16 Mbit SPI-only, 85 MHz max, 4 KByte sectors, no OTP Security ID, supports QPI mode only via command set extension | No native SQI interface; QPI requires separate enable command and lacks SIO[3:0] pin multiplexing flexibility | Select when existing Cypress ecosystem integration exists and SQI pin efficiency is not required. |
Compared with SST26VF016BA-104I/MF, W25Q16JVSIQ offers higher SPI clock speed but omits SQI bandwidth scaling and OTP security features, while S25FL116K0XMFI011 provides QPI compatibility yet lacks the integrated hardware write-lock-down and factory-unique ID essential for secure boot implementations.

FAQ
What is the maximum clock frequency supported by SST26VF016BA-104I/MF in SQI mode?
The SST26VF016BA-104I/MF supports up to 80 MHz in SQI mode when operated within the 2.3–3.6 V supply range. This is specified in the official Microchip datasheet DS20005262C, where SQI timing parameters are explicitly defined for that voltage window. The 104 MHz rating applies only to SPI mode under 2.7–3.6 V conditions. Exceeding 80 MHz in SQI mode may result in timing violations and data corruption.
Does SST26VF016BA-104I/MF support both SPI and SQI protocols simultaneously?
No, SST26VF016BA-104I/MF does not operate in both SPI and SQI modes simultaneously. It defaults to SPI mode after power-on reset and transitions to SQI mode only upon receiving the EQIO command. The IOC bit in the Configuration register must be set to '1' to enable SIO[2:3] as bidirectional data lines. Once in SQI mode, standard SPI commands like 03H or 0BH are invalid unless the device is reset or RSTQIO is issued.
How is hardware write protection implemented on SST26VF016BA-104I/MF?
Hardware write protection on SST26VF016BA-104I/MF is implemented via the WP# pin (SIO2), but only when the WPEN bit is set to '1' and the IOC bit is '0' in the Configuration register. In this state, pulling WP# low disables writes to the Block-Protection and Configuration registers. The factory default has WPEN = '0', so WP# is disabled at power-up unless explicitly enabled via WRSR. This design prevents accidental lock-down during system initialization.
Can the Security ID area of SST26VF016BA-104I/MF be erased or rewritten after programming?
No, the Security ID area of SST26VF016BA-104I/MF cannot be erased or rewritten after programming. The factory-programmed 64-bit segment is permanently fixed. The user-programmable 2 KByte segment can be written once using the PSID command, and then permanently locked using the LSID command. Once LSID executes, the SEC bit in the Status register becomes '1' and remains '1' for the device's lifetime - no power cycle or command resets it.
What package type does SST26VF016BA-104I/MF use, and is it pin-compatible with other variants in the SST26VF016B family?
SST26VF016BA-104I/MF uses an 8-contact WDFN package (6 mm × 5 mm). It shares identical pinout and electrical characteristics with other SST26VF016B variants in WDFN-8, SOIC-8, and SOIJ-8 packages per Microchip's pin assignment diagrams (Figures 2-1 to 2-3). However, mechanical footprint and thermal characteristics differ across packages - direct PCB substitution requires layout verification for solder joint reliability and thermal dissipation.
