PICAXE-20M2 microcontroller chip. Supports 16 input / outputs including analogue inputs.


Description [Hide]

A compact but powerful, PICAXE microcontroller. Very popular due to its low cost and small size.

The new PICAXE-20M2 microcontroller builds on the pedigree of the ever popular 20 pin PICAXE microcontrollers by adding new and improved features at no extra cost.

Specifications

  • Up to 8 separate tasks in parallel.
  • Almost every pin is individually configurable, up to 14 outputs.
  • Program memory capacity has been increased to 2048 bytes (about 1800 lines of code)
  • There are now 512 general purpose variables that can be addressed directly or indirectly
  • Data memory 512 bytes
  • A new "time" variable increments every second
  • Many more ADC channels are now available
  • Touch sensing is available on each analog input
  • A Digital to Analog Converter is included and there is an internal Fixed Voltage Reference
  • Operation between 1.8 and 5.5 volts (brownout detection is 1.9 volts and must be disabled for lower voltage operation)
  • Clock frequencies up to 32MHz (4MHz default)
  • Serial download pins can be used as general purpose I/O pins
  • Timeouts are available for serial, infra-red, and keyboard commands
  • Enhanced LED flashing and connectivity for play and tune commands
  • Servo command has been updated to reduce jitter and operates and 4 and 16MHz clock frequencies
  • Infra-red input and output on any pin
  • Manchester encoding is available for radio transmission
  • I2C
  • More PWM outputs
  • Longer nap delays
  • Weak pull-ups can be configured on input pins. Supports TTL and ST
  • Hardware serial port for higher baud rates and internal buffering for serial input
  • SR latch
  • Backwards compatible with programs written for M series chips by adding "let dirsB = 255" at the beginning of a program
  • Chip name is printed on the chip
