Overview

The ATMEGA8A-MU is a microcontroller Unit made by Microchip Technology in a VQFN-32-EP(5x5) package with 33 pins. -40℃~+85℃ 10bit 16MHz 1KB 2.7V~5.5V 23 512Byte 8 Bit 8KB AVR Built-in FLASH QFN-32-EP(5x5) Microcontrollers (MCU/MPU/SOC) ROHS.

PCBKit's library has its KiCad symbol (MCU_Microchip_ATmega:ATmega8A-M, from KiCad's library) and its footprint (Package_DFN_QFN:QFN-32-1EP_5x5mm_P0.5mm_EP3.1x3.1mm, from KiCad's library), ready for a KiCad board. 135 are in stock at JLCPCB (part C68004). 3 open-source boards in 3 repositories on GitHub use it.

Questions

Is there a KiCad symbol and footprint for the ATMEGA8A-MU?

Yes. The symbol is MCU_Microchip_ATmega:ATmega8A-M and the footprint Package_DFN_QFN:QFN-32-1EP_5x5mm_P0.5mm_EP3.1x3.1mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the ATMEGA8A-MU?

VQFN-32-EP(5x5), with 33 pins. Its footprint is drawn on this page.

Where is the ATMEGA8A-MU datasheet?

Microchip Technology publishes it: the Datasheet link on this page opens it.

Where can I order the ATMEGA8A-MU?

JLCPCB lists it as part C68004, with 135 in stock; the sellers' links on this page open their listings.

What can replace the ATMEGA8A-MU?

Parts like it in the library: the ATMEGA328P-MU by Microchip Technology, the ATXMEGA16E5-MU by Microchip Technology, the ATTINY261A-MN by Microchip Technology and the ATMEGA168-20MQ by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the ATMEGA8A-MU?
