CANedge2 Docs, Release FW 01.04.02
0.2 Specification
0.2.1 CAN-bus (x2)
• Physical
– Two physical CAN-bus interfaces
– Industry standard DB9 (D-sub9) connectors
• Transceiver
– Compliant with CAN Protocol Version 2.0 Part A, B and ISO 11898-1
– Compliant with ISO CAN FD and Bosch CAN FD
– Ideal passive behavior when unpowered (high impedance / no load)
– Protection: ±16kV HBM ESD, ±15kV IEC ESD, ±70 V bus fault, short circuit
– Common mode input voltage: ±30V
– TXD dominant timeout (prevents network blocking in the event of a failure)
– Data rates up to 5Mbps

• Controller
– Based on MCAN IP from Bosch
– Bit-rate: Auto-detect (from list
2
), manual simple (from list
3
) or advanced (bit-timing)
– 128 standard CAN ID + 64 extended CAN ID filters (per interface)
– Advanced filter configuration: Range, mask, acceptance, rejection, down sampling
– Configurable transmit messages, single shot or periodic (up to 128/64 regular/extended)
– Support for Remote-Transmission-Request (RTR) frames
– Silent mode: Restricted (acknowledge only) or monitoring (transmission disabled)
– Supports all CAN based protocols (J1939, CANopen, OBD2, NMEA 2000, . . . )

• Application
– Control reception (logging) and transmission states using CAN-bus control message
– Heartbeat signal to broadcast device time, space left of SD-card and rx/tx state
0.2.2 LIN-bus (x2)
• Physical
– Two physical LIN-bus interfaces
– Industry standard DB9 (D-sub9) connectors
• Transceiver
– Protection: ±8kV HBM ESD, ±1.5kV CDM, ±58V bus fault
– Supports 4V to 24V applications
– TXD dominant timeout (prevents network blocking in the event of a failure)
– Data rates up to 20kbps
