The MSPM0H series of microcontrollers include Universal Asynchronous Receiver-Transmitter (UART). As shown in Table 7-3, UART0 through UART7 support the LIN, DALI, IrDA, ISO7816 Manchester Coding function.

The MSPM0H UART module can support up to 10MHz baud date in Power Domain1 for almost all UART applications.

The MSPM0H UART module can support up to 3MHz baud date, this can support almost all UART applications.

Local Interconnect Network (LIN) is a commonly used low-speed network interface that consists of a commander node communicating with multiple remote responder nodes. Only a single wire is required for communication and is commonly included in the vehicle wiring harness.

The TLIN1021A-Q1 transmitter supports data rates up to 20kbps. The transceiver controls the state of the LIN bus by the TXD pin and reports the state of the bus on the open-drain RXD output pin. The device has a current-limited wave-shaping driver to reduce electromagnetic emissions (EME).

The TLIN1021A-Q1 is designed to support 12V applications with a wide input voltage operating range. The device supports low-power sleep mode and wake-up from low-power mode over LIN, the WAKE pin, or the EN pin. The device allows for system-level reductions in battery current consumption by selectively enabling the various power supplies that can be present on a node through the TLIN1021A-Q1 INH output pin. Figure 7-1 shows a typical interface implemented using the TI TLIN1021A LIN transceiver.

Only a single wire is required for communication and is commonly included in the vehicle wiring harness. Figure 7-2 and Figure 7-3 show typical interfaces implemented using the TI TLIN1021A LIN transceiver.
