PICAXE40 - (PICAXExx) Microcontroller

Download the PICAXE40 datasheet PDF. This datasheet also covers the PICAXE18 variant, as both devices belong to the same (picaxexx) microcontroller family and are provided as variant models within a single manufacturer datasheet.

Key Features

  • with the following enhancements:.
  • Program memory 8x as long (approx. 600 lines rather than 80), with intelligent download.
  • User configurable pins on PICAXE-28X and PICAXE-40X.
  • Continously driven pwm motor drive outputs (pwmout command).
  • Count high frequency pulses within a set time period (count command).
  • Increased data memory (128/256 bytes) (read/write commands).
  • i2c bus support for.

PICAXE Microcontroller Summary... PICAXE Type PICAXE-08 PICAXE-08M PICAXE-18 PICAXE-18A PICAXE-18X PICAXE-28A PICAXE-28X PICAXE-40X IC Size 8 8 18 18 18 28 28 40 Memory (lines) 40 80 40 80 600 80 600 600 I/O Pins 5 5 13 13 14 20 21 32 Outputs Inputs ADC (L =low) 1L 3 3L 3 3 4 0-4 3-7 Data Memory 128 - prog 256 - prog 128 - prog 256 256 + i2c 64 + 256 128 + i2c 128 + i2c Polled Interrupt Yes Yes Yes Yes 1-4 1-4 8 8 9 8 9-17 9-17 1-4 1-4 5 5 5 8 0-12 8-20 Notes: The number of memory program lines is approximate as different commands require different amounts of memory. The data memory can be used for storing data values or LCD messages. On the entry level PICAXE-08/18 this memory is shared with the downloaded program and so a longer program decreases the available data memory.
