PIC18F4550 Chip and Development Kit BRAND NEW


PIC18F4550 microcontroller

The PIC18F4550 is a high performance yet easy to program CMOS flash based 8-bit microcontroller with USB support! It packs Microchip’s powerful PIC architecture into a 40-pin package with 256 bytes of EEPROM, In-Circuit Debugging, 2 Capture/Comprae/PWM modules, 8 channels of 10-bit digital to analog converter, a synchronous serial port that can be configured for SPI or I2C, an Addressable Universal Asynchronous Receiver Transmitter (AUSART) serial port and USB support.

This huge list of features makes the PIC18F4550 ideal for almost any environment including manufacturing equipment, instrumentation, data acqusition, power conditioning, environmental monitoring, telecoms, consumer audio/video applications and input devices!

We offer two options for purchasing the PIC18F4550:

  • Option 1: just the chip
  • Option 2: a Getting Started kit

Option 1: Just the chip

This option is just the chip itself – no extras! You want this option if you already have your own design, or if you need to replace an existing PIC18F4550 chip ready to upload your code to the chip.

Option 2: PIC18F4550 kit

This kit contains everything you need to get started with the PIC18F4550 – all you need to supply is a PIC programmer to upload your code and a breadboard!


  • PIC18F4550 8-bit microcontroller
  • A 20MHz crystal oscillator and appropriate capacitors
  • 4 10KΩ resistors
  • 3 330Ω resistors
  • 4 push buttons
  • 3 LEDs
  • A 100nF capacitor for smoothing the power rails – this should be connected between your VDD and VSS rails

Is programming with C confusing? No problem!

We are an authorised reseller of the OshonSoft BASIC programming tools! Take a look at our buyhere22 listing: OshonSoft programming tools.
