Product details
Overview
SST26VF016B-104I/SM from Microchip Technology is a 16 Mbit Serial Quad I/O™ (SQI™) flash memory IC operating at 104 MHz (2.7–3.6 V) or 80 MHz (2.3–3.6 V), supporting x1/x2/x4 SPI and full SQI protocols, with 4 KByte uniform 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 IoT edge nodes.
For engineers reviewing the SST26VF016B-104I/SM datasheet, SST26VF016B-104I/SM pinout, SST26VF016B-104I/SM application, or SST26VF016B-104I/SM equivalent, key selection considerations include quad-I/O throughput vs. legacy SPI compatibility, flexible block protection granularity (8/32/64 KByte overlay blocks), and hardware write-protection via WP# pin with lock-down capability.
Technical Context
The SST26VF016B-104I/SM implements a six-wire SQI interface (SCK, CE#, VDD, VSS, SIO[3:0]) enabling 4-bit multiplexed command/address/data transfer-quadrupling bandwidth over standard SPI at identical clock frequency. Its SuperFlash® split-gate cell architecture delivers faster erase (sector: 18 ms typ) and lower active current (15 mA @ 104 MHz) versus conventional NOR flash.
It supports dual operational modes: default SPI mode (SI/SO pins active) after power-on reset, and configurable SQI mode (SIO[3:0] bidirectional) enabled via EQIO command. Mode 0 and Mode 3 clock polarity compatibility ensures interoperability with diverse host controllers, while HOLD# and WP# pins provide hardware-level control for read suspension and register write protection.

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 | 16 Mbit, 133 MHz max, 1.65–3.6 V supply, no SQI support, only standard SPI/x4 Quad SPI | Lacks SQI protocol and HOLD#/WP# hardware control; uses different security register model | Select when maximum clock speed >104 MHz is required and SQI interface is unused. |
| Cypress S25FL116K | 16 Mbit, 104 MHz max, 2.7–3.6 V, supports QPI but no write-suspend or non-volatile lock-down | No suspend/resume functionality; lacks OTP Security ID and permanent block lock-down bits | Select for cost-sensitive designs where firmware update atomicity and device identity security are not required. |
Compared with W25Q16JW and S25FL116K, the SST26VF016B-104I/SM uniquely combines SQI bandwidth, hardware-assisted write-suspend, and one-time programmable security features-making it optimal for safety-critical or update-intensive embedded systems requiring both performance and tamper resistance.

FAQ
What is the maximum operating frequency of the SST26VF016B-104I/SM and under what voltage conditions?
The SST26VF016B-104I/SM achieves a maximum clock frequency of 104 MHz when operated within the 2.7–3.6 V supply range. At the extended 2.3–3.6 V range, its maximum frequency is 80 MHz. These ratings are specified across the full industrial temperature range (–40°C to +85°C), and the device maintains full command compatibility-including SQI and SPI modes-at both speeds. The SST26VF016B-104I/SM datasheet confirms these values in Section 1.0 "Features" and Table 5-1 "Device Operation Instructions."
Does the SST26VF016B-104I/SM support true quad-I/O (SQI) mode, and how is it enabled?
Yes, the SST26VF016B-104I/SM supports true Serial Quad I/O™ (SQI) mode using all four SIO[3:0] pins for bidirectional command, address, and data transfer. SQI mode is enabled by first setting the IOC bit (Bit 1) in the Configuration Register to '1', then issuing the EQIO (38H) command. After this sequence, SIO[0]–SIO[3] operate as multiplexed I/O lines-unlike default SPI mode where SI and SO are separate. This capability is documented in Sections 4.0 and 4.6.1 of the SST26VF016B-104I/SM datasheet.
How does the SST26VF016B-104I/SM implement hardware write protection, and what pins are involved?
The SST26VF016B-104I/SM implements hardware write protection using the WP# pin in conjunction with the WPEN bit (Bit 7) and IOC bit (Bit 1) in the Configuration Register. When IOC = 0 and WPEN = 1, driving WP# low disables writes to the Block-Protection and Configuration Registers. The SST26VF016B-104I/SM defaults to WPEN = 0 at power-up, so WP# is inactive unless explicitly enabled. This behavior is defined in Section 4.2 "Hardware Write Protection" and Table 4-1 of the SST26VF016B-104I/SM datasheet.
What memory protection mechanisms does the SST26VF016B-104I/SM offer beyond standard software write protection?
Beyond standard software block protection, the SST26VF016B-104I/SM provides three hardened protection layers: (1) volatile lock-down of the Block-Protection Register (LBPR command), (2) non-volatile one-time programmable lock-down (nVWLDR register, E8H command), and (3) OTP Security ID lock (LSID command). Once programmed, nVWLDR bits permanently fix corresponding block write-lock states-even across power cycles. These features are detailed in Sections 4.1.2, 4.1.3, and 4.3 of the SST26VF016B-104I/SM datasheet.
Is the SST26VF016B-104I/SM AEC-Q100 qualified, and what temperature grades are available?
Yes, the SST26VF016B-104I/SM is explicitly AEC-Q100 qualified for automotive applications. It is offered in Industrial (–40°C to +85°C), Industrial Plus (–40°C to +105°C), and Extended (–40°C to +125°C) temperature grades. The "I" suffix in SST26VF016B-104I/SM denotes the Industrial grade. All variants meet AEC-Q100 stress test requirements, including HTOL, TCT, and ESD testing-confirmed in the "Features" section and Section 1.0 of the SST26VF016B-104I/SM datasheet.
