TMC8100ATG+

Encoders, Decoders, Converters Overview

The TMC8100ATG+ is a universal encoder bus controller IC designed for absolute and incremental encoder protocols. It operates as a bus controller or peripheral connected via SPI, UART, or I2C to motion controllers. The device supports synchronous protocols including SSI, SPI, BiSS-C, and EnDat 2.x, alongside asynchronous protocols like Nikon A-format. It features an integrated serial communication engine with data rates up to 16Mb/s, a programmable CRC generator, and counter/timer units. Operating on a single supply voltage of 2.25V to 5.5V, it functions within a temperature range of -40°C to +125°C. The component is housed in a TQFN-24 package measuring 4mm x 4mm.

Encoders, Decoders, Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct RoHS compliance status and package variant. Confirm that the TQFN-24 footprint matches the target PCB land pattern design. Ensure the power supply rail meets the specified 2.25V to 5.5V operating range before integration into the final assembly process.

Encoders, Decoders, Converters Selection Notes

Select this component when multi-protocol encoder compatibility is required in space-constrained designs. The internal PLL and clock generator reduce external component count compared to discrete solutions. Verify that the host microcontroller supports the necessary SPI or UART baud rates for real-time position feedback requirements.

Encoders, Decoders, Converters Part Context

The TMC8100 belongs to the Trinamic family of motion control components under Analog Devices. It serves as a specialized interface bridge between various encoder types and central processing units. This series focuses on simplifying encoder integration by handling protocol translation internally, allowing designers to standardize on a single controller IC across different machine architectures.
