TJA1020T/N,112

The TJA1020T/N,112 is an automotive transceiver chip used in any vehicle applications which require the communication of data. Developed by NXP Semiconductors, it is a System Basis Chip (SBC) which supports the bus protocols used in vehicles, such as CAN and Controller Area Network (J1850), as well as LIN (Local Interconnect Network) and FlexRay.

This chip utilizes a standard surface-mount package allowing for simplified PCB design and a low cost of integration. It also features a robust design which meets safety requirements for operational temperature ranges and load dump.

The TJA1020T/N,112 provides an automotive transceiver in the architecture of a System Basis Chip (SBC). This chip is used mainly in applications which require the communication of digital data using the CAN, LIN and FlexRay bus protocols. In addition, the TJA1020T/N,112 has a low-power sleep mode, which is ideal for applications in which power consumption needs to be minimized.

The TJA1020T/N,112 is includes a microcontroller, analog front end, and active processes and is controlled by a 32-bit ARM Cortex M0 processor core. It has a single CAN bus and two LIN buses, which offer enhanced communication performance. It also features a 32 MHz crystal oscillator and 12-bit ADC (Analog to Digital Converter).

The TJA1020T/N,112 transceiver is designed to meet the requirements for automotive EMC/EMI (electromagnetic compatibility/electromagnetic interference) standards. It has transceivers for the three types of bus protocols - CAN, LIN, and FlexRay - and built-in protocol checkers which can detect bus protocol frames and determine their validity.

The device also supports a high data rate, up to 1 Mbit/sec for CAN, which is a lot faster than current vehicles which can only operate at 500 Kbits/sec. The TJA1020T/N,112 has a self-test mode which performs built-in self-tests and simplifies system integration.

In terms of power management, the TJA1020T/N,112 offers full Sleep Mode and Active Mode. The Active mode is 30 mA typical at 3.6 V and the Sleep Mode is 0.1µA typical at 3.6 V. The device also features a low-noise design, which helps minimize system noise.

The TJA1020T/N,112 transceiver is a powerful and robust chip, suitable for any vehicle applications which require the communication of digital data using the various bus protocols. Its performance and built-in features make it an ideal choice for automotive systems and applications.
