UJA1023T/2R04,512

Controllers Overview

The UJA1023T/2R04,512 is a stand-alone Local Interconnect Network (LIN) I/O slave designed for electronic control units. It integrates an LIN 2.0 controller and transceiver compliant with SAE J2602, alongside a 30 kΩ termination resistor. The device features eight bidirectional I/O pins configurable via the LIN bus, supporting standard input/output, local wake-up, edge capturing, analog input, and switch matrix functions. Outputs can operate as high-side, low-side, or push-pull drivers, including PWM mode. An integrated on-chip oscillator enables automatic bit rate synchronization between 1 kbit/s and 20 kbit/s. The component operates within a supply voltage range of 6.5 V to 27 V and supports an extended ambient temperature range from -40 °C to +125 °C.

Controllers Procurement Notes

Verify that the ordering suffix matches the specific package and tape-and-reel configuration required for your assembly line. Confirm the voltage operating range specifications align with your system's battery supply characteristics. Ensure compatibility with the LIN master node addressing scheme before deployment.

Controllers Selection Notes

Select this component when a combined LIN transceiver and I/O expansion solution is needed in a single package. Consider the SO16 plastic small outline package dimensions for PCB layout constraints. Evaluate the need for the integrated oscillator and termination resistor against discrete alternatives to simplify design complexity.
