The latest developments in SENT protocol

Protocol is a digital communication standard designed specifically for point-to-point data transmission between sensors and ECU (Electronic Control Unit) in the field of automotive electronics

The full name is Single Edge Nibble Transmission protocol

The core specification is based on SAE J2716 (the latest version being SAE J2716-201604 released in 2016) and is one of the key technologies for digital transmission of sensors in modern automobiles

1. The application scope continues to expand

By 2025, the global market size of SENT protocol sensors will reach 2.3 billion US dollars, with an annual growth rate of 15%, and the growth rate in the fields of electric vehicles and autonomous driving will exceed 25%; Europe, North America, and China have become the three core markets of the SENT agreement, with China's penetration rate increasing from 32% in 2023 to 8% in 2025

2. Integration and innovation with other protocols

SENT over CAN FD: Achieving seamless integration of single point SENT sensors with CAN networks, which has been applied in the field of commercial vehicles

SENT+TSN: Combining time sensitive networks with SENT to solve synchronization problems in distributed control systems, particularly suitable for wire controlled steering and wire controlled braking

SENT SPC (Infineon Extended): Supports ECU to obtain sensor data on demand through main trigger pulse (MTP), reducing bus load by 30%

The SENT protocol is entering a golden period of development, fully penetrating from traditional engine sensors to new energy three electric systems and autonomous driving

The core highlights of 2025 include accelerated development of SENT-B protocol, intensive launch of new products by sensor manufacturers, explosive patent innovation, and breakthroughs in market application scale
