4.2 Digital Core

The TCAN1167-Q1 contains an internal digital core that operates the device and contains several diagnostic features such as: TXD dominant time out timer, SPI communication processor and addressable registers, time out, windowed, or Q&A watchdog timer, and the sleep wake error timer. The digital core also interfaces with the internal EEPROM memory and has CRC checking capability to ensure good data retention.

The following sections provide the functional safety mechanisms that cover the digital core:
