The PICAXE-40X2 IC is the biggest, baddest PICAXE made - even better than the 40X1!

Additional Information [Hide]

The 18F45K22 version of the PICAXE-40X2 is the newest revision of the popular 40 series, this new chip replaces both of the discontinued PIC18F4520 (40X2-5V) and the PIC18F45K20 (40X2-3V). This new revision adds more great specs on top of additional ADC channels, and new support for touch sensors and RFIN & RFOUT commands. Now you're working with a even more powerful micro, and still not having to crack a book on "C" programming!


·      Up to 4 internal program slots and 32 external program slots

·      RAM, up to 256 bytes + 1024 bytes scratchpad

·      Increased operating speed, up to 64Mhz (16Mhz internal)

·      Individual pin input/output control

·      26 ADC configurable pins now available

 These are the new 40X2 specifications:

·      2.1 to 5.5 volt operation

·      1000 lines of code

·      33 Configurable I/O

·      Hardware I2C support for easy peripheral connecting

·      Internal Timer

·      Increased variables and separate memory scratchpad

·      Enhanced mathematical functions

·      Line-by-line simulation

·      Supports

o  Interrupts

o  12-Bit Digital temperature sensors

o  Servo control

o  Keyboard input

o  IR transmit/receive

o  Plays user-defined musical tones

o  PWM Motor control

o  New HPWM module with power steering

o  Input Pulse counting

o  Serial output & debugging via programming cable

o  Increased optional clock speed, 64MHz external, 16MHz internal

o  Many additional ADC Channels, with individual ADC pin masking

o  New support for touch sensors on all ADC channels

o  Added support for RFIN and RFOUT commands for Manchester encoded wireless radio communication

o  New SR latch, voltage reference and DAC output modules

o  Higher baud rate for serial work (default now 9600, n, 8, 1)  

·      Based on the PIC 18F45K22 IC

 Almost all existing 40X2-5V and 40X2-3V programs can be used immediately on the new 40X2 chip. The only change that may be required is editing the format of any ‘let adcsetup = ‘ command, as the new part has the more versatile ‘individual masking’ method instead of the original ‘sequential masking’ method used on t he 40X2-5V. See the ‘adcsetup’ command in part 2 of the PICAXE manual for more details.

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.
