The TCAN14xx family of devices interface CAN protocol controllers with the physical bus in accordance to the ISO 11898 standard. These devices are compatible with the ISO 11898 High Speed CAN (Controller Area Network) Physical Layer standards: 11898-2. TCAN1462-Q1 is designed to support CAN FD data rates of 5 Mbps. It includes many protection features providing device and CAN network robustness.

Table 3-1 EVM Connection Settings for TCAN1462
Connection Description
J1 Mode selection: Pull up to VCC for standby mode, pull down to GND for normal mode
J2 Connection for access to all critical digital I/O, supply, and GND if being externally driven by test equipment or interfaced to a processor EVM. Note: ensure that J1, J9, J10 and T11 settings do not conflict with J2, if it is used.
J3/J4 CAN bus connection (CANH, CANL) and GND as necessary if interfacing EVM to a CAN network
J5 Connect if necessary for a single CAN network termination
J6 Connect, if necessary, in parallel with JMP5 to get a 60-Ω load to measure CAN parametrics

J7/J8

Connect if wanting to operate using the on-board SIC network.
J10 TCAN1462 VIO - Level-shifting for applications that require 3.3-V operation. Connect to 5-V supply for 5-V applications and 3.3-V for 3.3-V applications.
