PIC18F25K80-I/SS Typical application Circuitry

PIC18F25K80-I SS

The PIC18F25K80-I/SS is a versatile microcontroller from Microchip, equipped with enhanced features suitable for low power, high performance, and connectivity applications. It offers efficient power management for battery-powered and power-sensitive applications due to its nanoWatt XLP technology.

Usage Scenarios:

This microcontroller finds its applications in various fields such as automotive (especially in OBD-II applications), industrial control, smart sensors, and battery management systems. Its built-in CAN interface makes it particularly suitable for automotive applications where vehicle diagnostic and monitoring are required.

Characteristic Parameters:

- Operating Voltage Range: 1.8V to 5.5V

- Flash Memory: 32KB

- RAM: 2KB

- EEPROM: 1KB

- 12-bit ADC with multiple channels

- Multiple communication interfaces including SPI, I2C, EUSART, and CAN

- Enhanced Mid-range Core with 48 MHz Maximum Frequency

OBD-II Reader Circuit Implementation:

Power Connections:

The power supply should be clean and regulated. Connect the VDD (pin 20) to a +5V power supply. The VSS (pin 8) should be connected to the ground. It is important to use a 0.1 UF decoupling capacitor close to the power supply pins to minimize voltage spikes.

Crystal Oscillator Setup:

A crystal oscillator is connected to OSC1 (pin 19) and OSC2 (pin 18). For instance, a 10 MHz crystal with two 22 pF capacitors to ground will stabilize the oscillator circuit.

CAN Interface:

Connect pin 14 (CANTX) to the input of the CAN transceiver and pin 15 (CANRX) to the output of the CAN transceiver. Ensure that the CAN bus has proper termination resistors (typically 120 ohms) at each end of the bus network.

ICSP Connection for Programming:

The PIC18F25K80-I/SS is programmed via ICSP (In-Circuit Serial Programming). The relevant pins are:

- MCLR (pin 1) which also serves as VPP during programming.

- PGC (pin 9) for the programming clock.

- PGD (pin 10) for the programming data.

These connections should be made accessible for the programming interface, such as a PICkit or ICD tool, to enable easy programming and debugging.

Design Considerations When Designing the Circuit：

- Electromagnetic Interference (EMI): For applications in an automotive environment, it's crucial to design the circuit with considerations for EMI suppression, including the use of shielded cables for connections and proper PCB layout techniques.

- Power Regulation: Ensure that the power supply can provide a stable output even with fluctuations in the input voltage, which is common in automotive power supplies.

- Temperature Range: Automotive environments can experience extreme temperatures. Verify that all components, especially the PIC18F25K80-I/SS, are rated for the expected temperature range.

- Fault Protection: Implement protection mechanisms such as transient voltage suppressors (TVS) on input/output lines to guard against voltage spikes.

- CAN Bus Protections: Include fail-safes like a CAN bus transceiver with features to handle errors and disturbances on the CAN network.

Incorporating the PIC18F25K80-I/SS in an OBD-II reader circuit involves meticulous attention to the power supply design, interface protections, and ensuring reliable communication through the CAN network. The circuit must be robust enough to handle the harsh conditions of an automotive environment while providing accurate diagnostics and data communication.
