UJA1023T Overview
The UJA1023 is a stand-alone Local Interconnect Network (LIN) I/O slave that replaces basic ponents monly used in electronic control units for input and output handling. The UJA1023 contains a LIN 2.0 controller, an integrated LIN transceiver which is LIN 2.0 / SAE J2602 pliant and LIN 1.3 patible, a 30 kΩ termination resistor necessary for LIN-slaves, and eight I/O ports which are configurable via the LIN bus. An automatic bit rate synchronization circuit adapts to any (master) bit rate between 1 kbit/s and 20 kbit/s. For this, an oscillator is integrated. The LIN protocol will be handled autonomously and both Node Address (NAD) and LIN frame Identifier (ID) programming will be done by a master request and an optional slave response message in bination with a daisy chain or plug coding function. The eight bidirectional I/O pins are configurable via LIN bus messages and can have the...
