Summary of ATMEL USB PROGRAMMER CIRCUIT ZIF SOCKET USBASP ATMEGA8
The article discusses an advanced Atmel AVR USB programmer circuit featuring a ZIF socket, compatible with various Atmel processors (8 to 40 pins). It highlights the design based on the USBasp project, programming capabilities for ATmega8 and ATmega48 microcontrollers, and the use of SMD capacitors on the PCB. Issues encountered with 40-pin microcontrollers due to open circuits are noted, suggesting adding jumpers or switches for improved functionality. The article also covers software aspects like drivers and programming tools such as avrburn and WinAVR, along with testing on Proteus ISIS.
Parts used in the Atmel AVR USB programmer:
- Atmel AVR microcontrollers (ATmega8, ATmega48, AT2313)
- ZIF socket (supporting 8-pin, 20-pin, 28-pin, 40-pin CPUs)
- USBasp USB programmer circuit components
- SMD ceramic capacitors (for oscillator circuit)
- PCB (printed circuit board)
- Oscillator (crystal or resonator for microcontroller clock)
- Jumpers or switches (for 40-pin processor circuit modification)

AVR USB PROGRAMMER NOTES
The bottom surface of the printed circuit boards used in the oscillator circuit capacitors SMD type can be used in this way we will look more regular types of SMD ceramic type of application for which we have used that.
After the printed circuit board design tests for 40-pin microcontroller was found a little problem in the design should pay attention to it.
In the pictures below you can see the road open circuit, is disconnected atmega8, at2313 in programming was not a problem but the 40-pin processor problems in creating 40-pin processor in this way need to combine this section, a “Jumper” or “switch, Key added,” If this process becomes easier.
