Using Atmega8 / Atmega168 standalone Early draft. NOTE: This page is very outdated and many of the links are dead. Please see What's this about? You can use the Atmega8 chip by itself in a breadboard or a prototyping board using just a few extra parts. Once you've got your app working nicely on your arduino board, you may want to make it smaller or cheaper.

If you just want to make it smaller, you might consider a prebuilt or, the Mini also gives you a few extra analog and PWM pins. If you also need to make it cheaper you can make your own circuit based around the atmega8 or atmega168 chip, adding just the bare-bones circuitry needed to support the chip.

Signal Integrity Simplified Eric Bogatin. I've written a boot loader for an ATmega1280 and I I thought I had all the bugs ironed out but then found that after it's written a page and I can see the pa. How to program Atmel AVR and ATMega Fuses. ATMega328p Datasheet. RELATED ITEMS. AVR-X Add-on. AVR-X Add-on. After programming these fuses.

Bare-bones circuit boards and parts are also available. This page aims to document how to do it yourself. Is it simple? Check out from, which shows the entire circuit for a standalone atmega8 (minus circuitry to talk with a computer). Not too complex.

Note that there's less than US $10 of components needed there (not counting the breadboard), even if you're buying singles. Where do I start? Watch, bearing in mind that the video isn't just showing atmega8 but also circuitry to allow it to talk to the PC over serial.

Your circuit may be simpler than this. Overview • get an atmega8 (or 168) chip. Buy, or take one out of your arduino board. • put your program onto it, somehow. • build a circuit to support the atmega chip • place the chip in the circuit Building the circuit A good starting point and the most comprehensive write-up so far is the which shows how to get an atmega8 up and running on breadboard, and then adds circuitry for a serial-over-USB connection, should you need it. There are a number of sources: • - includes a parts list and links to schematics.

• and (serial).

ATmega1280 In Production The high-performance, low-power Microchip 8-bit AVR RISC-based microcontroller combines 128KB ISP flash memory, 8KB SRAM, 4KB EEPROM, 86 general purpose I/O lines, 32 general purpose working registers, real time counter, six flexible timer/counters with compare modes, PWM, 4 USARTs, byte oriented 2-wire serial interface, 16-channel 10-bit A/D converter, and a JTAG interface for on-chip debugging. The device achieves a throughput of 16 MIPS at 16 MHz and operates between 2.7-5.5 volts. By executing powerful instructions in a single clock cycle, the device achieves a throughput approaching 1 MIPS per MHz, balancing power consumption and processing speed.
