For engineers reviewing the SST26VF016-80-5C-S2AE datasheet, SST26VF016-80-5C-S2AE pinout, SST26VF016-80-5C-S2AE application, or SST26VF016-80-5C-S2AE equivalent, this page delivers verified electrical specs, SQI/SPI dual-mode timing behavior, industrial temperature support (−40°C to +85°C), and real-world use cases in portable electronics requiring fast, low-power nonvolatile storage.

Technical Context

The SST26VF016-80-5C-S2AE implements a 4-bit multiplexed serial interface with Mode 0/Mode 3 compatibility, enabling up to 320 Mbit/s sustained data rate via quad I/O transfers. Its SuperFlash® technology uses split-gate cells and thick-oxide tunneling for enhanced endurance and retention.

It supports flexible erase architecture: uniform 4 KByte sectors, four 8 KByte top/bottom parameter blocks, two 32 KByte overlay blocks, and thirty 64 KByte overlay blocks - totaling 16 Mbit (2,097,152 bytes) addressable memory. The device boots in SPI mode and transitions to SQI mode via EQIO command.

FAQ

What interface protocols does the SST26VF016-80-5C-S2AE support?

The SST26VF016-80-5C-S2AE supports both SPI (Mode 0/Mode 3) and Serial Quad I/O™ (SQI™) protocols. It powers up in SPI mode for backward compatibility and switches to SQI mode upon receiving the EQIO command (0x38). In SQI mode, SIO[3:0] operate as bidirectional quad data lines, enabling 320 Mbit/s sustained throughput at 80 MHz-four times faster than standard SPI at the same clock rate. The SST26VF016-80-5C-S2AE maintains full command set compatibility across both modes.

Does the SST26VF016-80-5C-S2AE support execute-in-place (XIP) operation?

Yes, the SST26VF016-80-5C-S2AE supports true execute-in-place (XIP) operation due to its 80 MHz high-speed read capability and low-latency SQI interface. With High-Speed Read (0xBH) and continuous burst modes-including wrap-around and Index Jump-the device delivers deterministic access timing without requiring code shadowing into external SRAM. This reduces system BOM cost and power consumption in portable applications like GPS units and Bluetooth headsets where the SST26VF016-80-5C-S2AE is commonly deployed.

What is the memory organization of the SST26VF016-80-5C-S2AE?

The SST26VF016-80-5C-S2AE organizes its 16 Mbit array into uniform 4 KByte erasable sectors plus specialized overlay blocks: four 8 KByte top parameter blocks, four 8 KByte bottom parameter blocks, two 32 KByte overlay blocks (one top, one bottom), and thirty 64 KByte overlay blocks. This structure totals 2,097,152 bytes and enables flexible firmware partitioning-such as isolating bootloader, application, and calibration data-while maintaining high endurance across all regions. The SST26VF016-80-5C-S2AE's block protection register allows independent locking of each region.

How does the Security ID feature work on the SST26VF016-80-5C-S2AE?

The SST26VF016-80-5C-S2AE includes a 256-bit One-Time Programmable (OTP) Security ID: 64 bits are factory-programmed with a unique identifier and cannot be altered; the remaining 192 bits are user-programmable for device-specific keys or certificates. Programming uses the Program SID (0xA5) command, and locking is performed via Lockout SID (0x85), which permanently disables further writes to the entire Security ID space. Once locked, the SEC bit in the status register reads '1', and the SST26VF016-80-5C-S2AE enforces read-lock behavior for protected blocks.

What are the power consumption characteristics of the SST26VF016-80-5C-S2AE?

The SST26VF016-80-5C-S2AE draws 12 mA typical active read current at 80 MHz and only 8 µA typical standby current-enabling extended battery life in portable applications. Its single 2.7–3.6 V supply simplifies power design, and SuperFlash® technology minimizes total energy per erase/program cycle through lower current draw and shorter erase times (e.g., 18 ms typical for 64 KByte block erase). These characteristics make the SST26VF016-80-5C-S2AE ideal for always-on IoT sensors and wearable devices where the SST26VF016-80-5C-S2AE operates across wide temperature ranges.
