3.5.15 TWAI
®
Controller
The Two-wire Automotive Interface (TWAI) is a multi-master, multi-cast communication protocol with error
detection and signaling as well as inbuilt message priorities and arbitration. The TWAI controller in ESP32-S3
supports the following features:
• Compatible with ISO 11898-1 protocol (CAN Specification 2.0)
• Standard frame format (11-bit ID) and extended frame format (29-bit ID)
• Bit rates from 1 Kbit/s to 1 Mbit/s
• Multiple modes of operation:
– Normal
– Listen Only
– Self-Test (no acknowledgment required)
• 64-byte receive FIFO
• Acceptance filter (single and dual filter modes)
• Error detection and handling:
– Error counters
– Configurable error interrupt threshold
– Error code capture
– Arbitration lost capture
For more information, please refer to Chapter Two-wire Automotive Interface (TWAI®) in ESP32-S3 Technical
Reference Manual.
3.6 Radio and WiFi
The ESP32-S3 radio consists of the following blocks:
• 2.4 GHz receiver
• 2.4 GHz transmitter
• Bias and regulators
• Balun and transmit-receive switch
• Clock generator
