Product details
Overview
SST26VF016B-80E/SM from Microchip Technology is a 16 Mbit Serial Quad I/O™ (SQI™) flash memory IC operating at 2.3–3.6V, supporting 80 MHz max clock frequency, 4 KByte uniform sectors, and x1/x2/x4 SPI-compatible serial interface. It delivers high-speed code execution and firmware storage in space-constrained embedded controllers and automotive infotainment systems.
For engineers reviewing the SST26VF016B-80E/SM datasheet, SST26VF016B-80E/SM pinout, SST26VF016B-80E/SM application, or SST26VF016B-80E/SM equivalent, key selection criteria include SQI vs. SPI mode compatibility, 80 MHz timing at 2.3V supply, 4 KByte sector erase granularity, WDFN-8 package footprint, and hardware write protection via WP# pin with non-volatile lock-down capability.
Technical Context
The SST26VF016B-80E/SM implements a six-wire, 4-bit multiplexed I/O interface (SIO[3:0]) enabling quad-data-rate transfers while maintaining full command-set compatibility with legacy SPI protocols (Mode 0/3). Its SuperFlash® split-gate cell architecture enables 100,000 program/erase cycles and >100 years data retention.
It supports flexible protection schemes including individual 8/32/64 KByte block write-lock, read-lock for parameter blocks, volatile lock-down (LBPR), and non-volatile write-lock lock-down (nVWLDR). The device ships with IOC=0 and WPEN=0 by default, enabling HOLD#/WP# pins in SPI mode and disabling hardware write protection until configured.

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, 1.8V supply, 133 MHz max, DTR support, no SQI mode, different security ID implementation | Lacks AEC-Q100 qualification and SQI interface; better suited for low-voltage consumer IoT than automotive | Select only if 1.8V operation and DTR read mode are required; verify absence of SQI does not impact throughput budget. |
| Cypress S25FL116K | 16 Mbit, 2.7–3.6V, 80 MHz max, no SQI, no Security ID, simpler protection scheme (no nVWLDR) | Lower security assurance; lacks OTP ID and non-volatile lock-down - insufficient for regulated medical or automotive Tier-1 use | Acceptable for cost-sensitive industrial HMI where firmware authenticity is not mandated; avoid where traceability or anti-cloning is required. |
Compared with SST26VF016B-80E/SM, W25Q16JW offers higher speed but sacrifices automotive qualification and SQI efficiency, while S25FL116K reduces cost and complexity at the expense of security features and long-term data integrity guarantees essential for safety-critical firmware storage.

FAQ
What is the maximum clock frequency supported by SST26VF016B-80E/SM?
The SST26VF016B-80E/SM supports up to 80 MHz maximum clock frequency when operated within the 2.3–3.6V supply range. This rating applies across its full Industrial Plus temperature range (–40°C to +105°C) and is validated for both SPI and SQI modes. At 2.7–3.6V, the device can operate up to 104 MHz, but the -80E/SM suffix denotes the 80 MHz speed grade, ensuring guaranteed timing margins under worst-case voltage and temperature conditions.
Does SST26VF016B-80E/SM support Quad I/O mode out of reset?
No, SST26VF016B-80E/SM powers up in standard SPI mode (x1) with IOC=0. To enable Quad I/O mode, the host must first issue the EQIO (38H) command and set the IOC bit in the Configuration register. Only after this configuration does SIO[3:0] become fully bidirectional for quad-speed transfers. Failure to configure IOC before issuing SQI-specific commands (e.g., 6BH, EBH) results in undefined behavior.
How is hardware write protection implemented on SST26VF016B-80E/SM?
Hardware write protection on SST26VF016B-80E/SM is controlled by the WP# pin in conjunction with the WPEN bit (bit 7) and IOC bit (bit 1) in the Configuration register. WP# is active-low and only functional in SPI mode when IOC=0 and WPEN=1. When asserted, it prevents writes to the Block-Protection and Configuration registers - not the main memory array. The factory default is WPEN=0, so WP# is disabled at power-up unless explicitly enabled via WRSR.
What package type is used for SST26VF016B-80E/SM?
SST26VF016B-80E/SM uses an 8-contact WDFN (WSON) package measuring 6 mm × 5 mm with exposed pad. This RoHS-compliant, surface-mount package provides low thermal resistance and compact footprint ideal for automotive and portable industrial designs. Pin assignments match the standard SOIC-8 and SOIJ-8 footprints electrically but differ mechanically - PCB layout must follow Microchip's WDFN-8 land pattern (DS20005262F, Figure 2-2).
Can SST26VF016B-80E/SM be used in automotive applications?
Yes, SST26VF016B-80E/SM is AEC-Q100 qualified for Automotive Grade 2 (–40°C to +105°C), making it suitable for engine control units, infotainment systems, and ADAS modules. Its SuperFlash® technology ensures 100,000 program/erase cycles and >100 years data retention under automotive thermal and vibration stress profiles. The -80E/SM suffix confirms qualification to this standard - always verify the specific date code and lot traceability documentation for Tier-1 compliance requirements.
