UJA1023T/2R04/C,51

UJA1023T/2R04/C,51 is a stand-alone Local Interconnect Network (LIN) I/O server 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 30Kohm termination resistor necessary for LIN-servers, and eight I/O ports which are configurable via the LIN bus. An automatic bit rate synchronization circuit adapts to any (host) 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 host request and an optional server response message in combination with a daisy chain or plug coding function.

• Automatic bit rate synchronization to any (host) bit rate between 1 kbit/s and 20 kbit/s
• Integrated LIN 2.0 / SAE J2602 transceiver (including 30Kohm termination resistor)
• Eight bidirectional I/O pins
• 4 x 2, 4 x 3, 4 x 4 switch matrix to support reading and supplying a maximum number of 16 switches
• Outputs configurable as high-side and/or low-side driver and as cyclic or PWM driver
• 8-bit ADC, advanced low-power behavior, on-chip oscillator
• Node Address (NAD) configuration via daisy chain or plug coding
• Inputs supporting local wake-up and edge capturing
• Configurable sleep mode, limp home configuration in error conditions, low electromagnetic emission
• Available in a 16 pin SO package, extended ambient temperature range (−40°C to +125°C)
