Description

This is LIN-I/O slave. UJA1023 LIN-I, O slave Rev. 5 17 August 2010 Product data sheet 1. General description The UJA1023 is a stand-alone Local Interconnect Network (LIN) I, O slave that replaces basic components commonly 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 compliant and LIN 1.3 compatible, 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 combination with a daisy chain or plug coding function. The eight bidirectional I, O pins are configurable via LIN bus messages and can h.
