The 20-pin PICAXE-20M IC is an affordable mid-range microcontroller, offering eight inputs and outputs and 80 lines of memory. Save some money when you don't need the power of an "X" series chip!


Description [Hide]

The PICAXE-20M IC is part of the mid-range educational lineup of PICAXE chips. It offers:

  • 80 lines memory
  • 8 inputs
  • 8 outputs
  • 4 8/10-bit Analog-to-Digital converters (ADC)
  • 8MHz maximum operation speed (4MHz normally)
  • Supports
    • Interrupts
    • Digital temperature sensors
    • Servo control
    • Keyboard input
    • IR transmit/receive
    • Plays user-defined musical tones
    • PWM Motor control
    • Input Pulse counting
    • Serial output & debugging via programming cable
  • Based on the PIC 16F677 IC

It's a solid microcontroller for those medium projects where you don't need the extra power of an "X" series chip!

The PICAXE system is a powerful, low cost microcontroller programming system designed to simplify educational and hobbyist use of microcontrollers. PICAXE chips can be programmed in a graphical 'flow-chart' environment or in easy to understand BASIC.

Memory (lines) = Approximate number of lines of program code the chip can hold.
Data Memory = Bytes of EEPROM memory on board. "128 (-Prog)" means 128 Bytes less the space needed for your program. 256+I2C means 256 Bytes + any external EEPROM space you add via the I2C interface).
Polled Interrupt = A process that automatically checks a pin in between each command to see if something has happened (very useful!)
