Product details
Overview
SST26VF016B-104V/MF from Microchip Technology is a 16 Mbit Serial Quad I/O™ (SQI™) flash memory IC supporting 2.3–3.6 V single-supply operation, 104 MHz SPI read speed (2.7–3.6 V), and 4 KByte uniform sector erase. It delivers 100,000 program/erase cycles and >100 years data retention for embedded boot code and firmware storage in industrial controllers.
For engineers reviewing the SST26VF016B-104V/MF datasheet, SST26VF016B-104V/MF pinout, SST26VF016B-104V/MF application, or SST26VF016B-104V/MF equivalent, key selection criteria include SQI vs. SPI mode compatibility, 8-lead SOIJ package footprint, write-suspend capability for real-time multitasking, and OTP Security ID for device authentication.
Technical Context
The SST26VF016B-104V/MF implements a six-wire, 4-bit multiplexed I/O interface (SIO[3:0]) with full backward compatibility to standard SPI x1/x2/x4 protocols. Its SuperFlash® split-gate cell architecture enables faster erase (18 ms sector, 35 ms chip) and lower active current (15 mA @ 104 MHz) versus conventional NOR flash.
It supports dual-mode operation: SPI Mode 0/3 with dedicated SI/SO pins, and SQI mode with quad-data transfer using SIO[3:0], enabled via EQIO command and IOC bit configuration. Memory protection includes volatile lock-down (LBPR), non-volatile write-lock (nVWLDR), and hardware WP#/HOLD# control active only in SPI modes.

FAQ
What voltage range does the SST26VF016B-104V/MF support for reliable operation?
The SST26VF016B-104V/MF operates across two validated supply ranges: 2.7–3.6 V (enabling 104 MHz maximum clock speed) and 2.3–3.6 V (supporting up to 80 MHz). Both ranges guarantee full functionality including program, erase, and read operations. The device uses a single supply - no auxiliary voltages are required. This dual-range flexibility allows system designers to optimize power efficiency while maintaining performance headroom in battery-powered or wide-input industrial power supplies.
Does the SST26VF016B-104V/MF support true quad I/O mode, and how is it enabled?
Yes, the SST26VF016B-104V/MF supports true Serial Quad I/O™ (SQI) mode using all four SIO[3:0] pins for simultaneous bidirectional data transfer. To enable SQI, the host must first set the IOC bit (bit 1) in the Configuration Register via WRCR, then issue the EQIO (38H) command. Once configured, instructions like SQOR (6BH) and SQIOR (EBH) become active. In SQI mode, WP# and HOLD# functions are disabled - their pins repurpose as SIO2 and SIO3. This mode quadruples effective bandwidth versus standard SPI at identical clock frequencies.
How does the Security ID feature work in the SST26VF016B-104V/MF?
The SST26VF016B-104V/MF includes a dedicated 2 KByte Security ID (Sec ID) space comprising a factory-programmed 64-bit unique identifier (read-only, unchangeable) and a user-programmable segment. Users write to the latter via the PSID command and permanently lock the entire Sec ID space using LSID. Once locked, no further writes are possible - the SEC bit in the Status Register becomes permanently '1'. This provides tamper-resistant device identity for secure boot, licensing, or anti-counterfeiting without requiring external security ICs.
What package type is used for the SST26VF016B-104V/MF, and what are its mechanical dimensions?
The SST26VF016B-104V/MF is packaged in an 8-lead SOIJ (Small Outline Integrated Circuit, J-bend) with a 5.28 mm body width. Pin pitch is 1.27 mm, and total package length is 5.0 mm. This RoHS-compliant package features gull-wing leads suitable for standard reflow soldering and offers superior moisture resistance compared to SOIC variants. It is pin-compatible with other members of Microchip's SST26VFxxxB family in the same SOIJ outline, enabling drop-in replacement within the same density and speed grade.
Is the SST26VF016B-104V/MF qualified for automotive applications, and what standards does it meet?
Yes, the SST26VF016B-104V/MF is AEC-Q100 qualified for automotive applications (Grade 2: –40°C to +105°C). It meets stress test requirements for temperature cycling, humidity bias, ESD, and accelerated life testing per AEC-Q100 Rev G. This qualification ensures reliability in under-hood and infotainment systems where thermal stability, long-term data integrity, and immunity to electrical transients are mandatory. The device also complies with RoHS Directive 2011/65/EU and is halogen-free.
