PIC18F2550-I/SO Typical application Circuitry

PIC18F2550-I SO

The PIC18F2550-I/SO is a versatile microcontroller chip designed by Microchip Technology, which is built upon a high-performance RISC CPU. This chip is well-suited for projects that require an embedded system with USB capabilities because it comes with a built-in full-speed USB 2.0 interface.

Key Features:

- High-Performance RISC CPU

- Flash Memory: 32KB

- RAM: 2KB

- EEPROM: 256 Bytes

- I/O Pins: 24

- 10-bit Analog-to-Digital Converter (ADC) with 13 channels

- Up to 48 MHz operating speed

- USB 2.0 Interface

Typical Application: USB Interface Device

The PIC18F2550-I/SO can be employed in numerous applications, one of which is a USB interface device that communicates between a PC and external hardware, such as a custom keyboard or a sensor interface.

Detailed Circuit Connection for a USB Interface Device:

Power Supply Connection:

- Connect the VDD (Pin 20) of the PIC18F2550-I/SO to a +5V power source.

- Connect VSS (Pin 19) to ground.

USB Communication:

- Connect D+ (Pin 23) to the D+ data line of the USB connector.

- Connect D- (Pin 24) to the D- data line of the USB connector.

- A 1.5 kΩ pull-up resistor may be required on D+ or D- depending on the USB speed desired.

Oscillator Configuration:

- Connect a crystal oscillator to OSC1 (Pin 13) and OSC2 (Pin 14) for an external clock source. The choice of the crystal value depends on the required USB communication speed.

- Place capacitors as per the crystal manufacturer's recommendation, usually around 22 pF, from each of these pins to ground.

Programming and Debugging Interface:

- For ICSP (In-Circuit Serial Programming), connect the following:

- MCLR (Pin 1) to the programming voltage pin of the programmer.

- PGD (Pin 28) to the data pin of the programmer.

- PGC (Pin 27) to the clock pin of the programmer.

- VDD and VSS should also be connected to the programmer to power the PIC during Indicator LEDs:

- Connect a series resistor and an LED to any of the I/O pins for visual feedback. For example, connect the anode of the LED to RC0 (Pin 15) through a 330 Ω resistor, with the cathode going to ground.

Design Considerations:

In designing with the PIC18F2550-I/SO, especially for USB applications, one must take into account the impedance matching and signal integrity for the USB lines. It's important to keep the D+ and D- traces as short as possible and with equal length to maintain signal integrity.

Furthermore, decoupling capacitors should be placed near the VDD pin to ensure clean power is supplied to the microcontroller. Additionally, the stability of the external crystal oscillator is paramount for the proper functioning of USB communication, so the crystal with correct load capacitors, as specified by the manufacturer, must be used.

When it comes to the USB firmware, implementing the USB stack correctly is crucial. The programmer should be familiar with the USB protocol and the Microchip USB framework if available for the PIC18F2550-I/SO.

The ADC, if used, will require careful analog design to ensure the signals are noise-free and the reference voltage is stable.

In all, creating a USB interface device with the PIC18F2550-I/SO demands a thorough understanding of USB communication, power supply design, and signal integrity principles, along with accurate firmware development that leverages the microcontroller's capabilities.
