UJA1023T/2R04,518

Controllers Overview

The UJA1023T/2R04,518 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 and compatible with LIN 1.3. The device features eight bidirectional I/O pins configurable via the LIN bus, supporting functions such as standard input/output, local wake-up, edge capturing, analog input, PWM output, and switch matrix operations. An integrated 30 kΩ termination resistor is included. Automatic bit rate synchronization adapts to master rates between 1 kbit/s and 20 kbit/s. Supply voltage ranges from 5.5 V to 27 V, with low-power consumption of approximately 5 μA in sleep mode.

Controllers Procurement Notes

Verify that the specific ordering suffix matches the required package variant and temperature range. Confirm compatibility with the target LIN master's configuration commands, particularly regarding NAD assignment methods like daisy chain or plug coding. Ensure supply voltage conditions align with the specified operating range for the selected variant.

Controllers Selection Notes

Select this component when a standalone LIN slave solution with flexible I/O configuration is required. Consider the integrated oscillator and automatic bit rate detection for simplified design. Evaluate the need for specific I/O functions such as PWM backlight illumination or analog input conversion via the internal ADC block before finalizing the part number.
