AVROs

Original AVROs are small AVRs with a Boot Loader & Auto Calibration 

  • The Convenience of a Stamp at the Cost of a Chip

  • Boot Loading for 8 Pin AVRs - even the 1k Tiny13

  • Download Program Code using a PC Serial Link

  • The Download Auto-Calibrates the AVR Internal Oscillator

  • No MAX232, No External Crystal, No Boot Jumper

  • Plus Download & Upload EEPROM Data Memory

  • $3.20 to $5.60 for 8 to 28 Pins

  • Affordable in all Classrooms, and without committing to one specific Programming Language

New - AVROs as Coprocessors with Updateable Firmware

The small Boot Loaders make it practical to include them alongside the Coprocessor's Firmware for easy Updates/Revisions and the Auto Calibration eliminates the need for a Crystal or Resonator:
AVRO-CP-SAR  (8 Pin)
AVRO-CP-3220 (28 Pin)
New - AVRO-GUI with new functionality alongside a High Speed Loader
 
This covers the high end range of AVRs that have code space allocated specifically for a Boot. In order to cover all devices in both DIP & SM packages, it is offered as customisable Firmware for the user to load directly into their own blank AVRs. That is the Green Segment above. It is  recognised that most if not all of the user boards will be using a Crystal, so the normal Calibration code space has been given to the GUI.
