In terms of features, the PIC18F97J60-I/PF includes:
- A 10 Mbps Ethernet MAC/PHY
- 128 KB of Flash memory
- 3,840 bytes of RAM
- An assortment of serial interfaces, such as UART, SPI, and I2C
- An 8 x 8 Single-Cycle Hardware Multiplier
Designing a Simple Networked Sensor Interface:
One practical application of the PIC18F97J60-I/PF could be a networked temperature sensor that can be monitored over a local network. Below is an overview of the necessary connections and considerations for such a design.
Power Supply and Grounding:
- VDD Connections: Power the PIC18F97J60-I/PF by connecting its VDD pins to a regulated 3.3V power supply. It is critical to connect all VDD pins to the power source to ensure proper operation.
- VSS Connections: Connect all VSS (ground) pins to the common ground of the circuit.
Ethernet Interface:
- RJ45 Connector: The integrated Ethernet controller of the PIC18F97J60-I/PF requires a connection to an RJ45 Ethernet jack with integrated transformers. Connect the TX and RX differential pairs to the corresponding pins on the PIC18F97J60-I/PF.
Temperature Sensor Interface:
- Analog Input: If using an analog temperature sensor, connect its output to one of the PIC's analog input pins, such as AN0. Before this connection, a low-pass filter may be beneficial to condition the signal.
Programming Interface:
- ICSP (In-Circuit Serial Programming): To program the PIC18F97J60-I/PF, you will use the following pins for ICSP:
- PGC (Pin 30): Program Clock
- PGD (Pin 31): Program Data
- MCLR (Pin 1): Master Clear/Reset pin, also used for applying the programming voltage.
Oscillator Configuration:
- Crystal Oscillator: Connect a crystal oscillator to OSC1 (Pin 11) and OSC2 (Pin 12) for an external clock source. For network timing, a precise frequency is important.
Circuit Protection and Filtering:
- Reset Circuit: Attach a pull-up resistor to the MCLR pin and a capacitor to ground to form a power-on reset circuit.
- Decoupling Capacitors: To stabilize the power supply, place decoupling capacitors in close proximity to the PIC18F97J60-I/PF power pins.
PCB Layout Points to Remember:
- Signal Integrity: Keep the traces from the crystal oscillator as short as possible and away from high-speed signals like the Ethernet lines.
- Thermal Management: If the sensor circuitry or Ethernet PHY will be operating at high speeds, pay attention to thermal dissipation.
Final Considerations:
When integrating the PIC18F97J60-I/PF into a circuit, one must consider the following:
- The quality of the power supply, as fluctuations can affect both the microcontroller's performance and the reliability of network communications.
- The firmware development, especially the TCP/IP stack required for Ethernet communication, which can be complex.
- The isolation of analog signals from the digital noise inherent in Ethernet communications.
- The need for robust Ethernet cabling and connectors to ensure signal integrity across the network.
By carefully attending to these design elements, the PIC18F97J60-I/PF can be effectively employed in a range of network-connected applications, leveraging its integrated Ethernet controller for communication within distributed systems.
