PIC18F25K80-E/SS Typical application Circuitry

The PIC18F25K80-E/SS is a high-performance microcontroller developed by Microchip Technology, optimized for applications requiring advanced communication capabilities. It belongs to the PIC18F K80 family and is particularly designed to operate in extended temperatures, making it suitable for automotive, industrial, and other robust environments. This microcontroller is equipped with Enhanced Flash memory technology and is compatible with the ECAN™ technology for advanced communication.

Application Scenarios:

The PIC18F25K80-E/SS can be used in various scenarios, including automotive systems, industrial automation, sensor monitoring, and data acquisition systems. One common application is in the automotive industry for engine control units (ECUs), diagnostics, and communication interfaces such as On-Board Diagnostics (OBD).

Parameter Features:

The key features of the PIC18F25K80-E/SS include:

- Operating Voltage: 2.0-5.5V

- Flash Memory: 32KB

- RAM: 1,024 bytes

- EEPROM: 128 bytes

- 10-bit, up to 12 channel Analog-to-Digital Converter (ADC)

- Two Enhanced Capture/Compare/PWM (ECCP) modules

- Enhanced Universal Synchronous Asynchronous Receiver Transmitter (EUSART)

- Enhanced Controller Area Network (ECAN) with dedicated DMA channels

- Two Comparators

- Up to 25 I/O pins

Example Circuit: OBD-II Interface:

Let's consider an application where the PIC18F25K80-E/SS is used to interface with a vehicle's OBD-II system. The circuit will read diagnostic data from the vehicle and communicate it to an external device, such as a diagnostics tool.

OBD-II Communication Interface Circuit:

1. Power Supply Connection:

Connect the VDD pins (pin 20 for the PIC18F25K80-E/SS) to a regulated 5V supply. The VSS pin (pin 8) should be connected to ground. Ensure the supply is filtered with decoupling capacitors (typically 100 nF ceramic close to the MCU and a 10 µF electrolytic on the supply line).

2. CAN Interface:

Connect the ECAN transceiver to the CANTX (pin 14) and CANRX (pin 18) pins of the PIC18F25K80-E/SS. This transceiver will then connect to the OBD-II connector's CAN high and CAN low lines. Use a 120-ohm resistor across the CAN lines for termination.

3. Crystal Oscillator:

A crystal oscillator is required for precise timing, especially for CAN communication. Connect a 10 MHz crystal to OSC1 (pin 19) and OSC2 (pin 18). Place two 22 pF capacitors from each OSC pin to ground.

4. Programming Interface:

For programming the PIC18F25K80-E/SS, use the PGC (pin 9) and PGD (pin 10) pins. These will connect to the programmer/debugger, such as the PICkit™ or MPLAB ICD.

5. Serial Interface for Debugging:

A serial interface can be established by connecting an RS232 transceiver to the TX (pin 17) and RX (pin 16) pins for debugging purposes or to interface with a computer.

Design Considerations:

- Decoupling and Filtering: Ensure that the power supply is stable with decoupling capacitors to minimize noise, which is critical in automotive environments.

- Clock Stability: The CAN module relies on precise timing; therefore, a stable clock source is crucial.

- CAN Bus Protection: Implement safeguards against transients on the CAN bus, using protection diodes and common-mode chokes.

- Thermal Considerations: Since the PIC18F25K80-E/SS can operate in extended temperatures, ensure the layout and design accommodate thermal expansion and cooling if necessary.

- Electromagnetic Compatibility (EMC): Layout the PCB to minimize electromagnetic interference, which can be prevalent in automotive applications.

When designing with the PIC18F25K80-E/SS, it is important to consider the robustness and reliability of the circuit, especially if it's intended for automotive use where conditions can be harsh. The EMC, temperature range, and power supply resilience are critical factors in ensuring the microcontroller operates reliably.
