![]() ![]() They have the same performance on AVR core architectures but ATMEGA328PB-AU has 5 extra I/Os. The ATMEGA328PB-AU is a backwards-compatible alternative to the popular ATMEGA328P-AU. Backwards-Compatible, improved replacement for the popular ATMEGA328P-AUĪs can be seen from the table, the ATMEGA328PB-AU AVR microcontroller also has 32 KB of flash program memory, 2 KB of RAM and the same footprint as ATMEGA328P-AU. Don’t fret, we will continue to update this list as we go along, and we hope you’ll be able to find one that satisfies your taste. Needless to say, the increasing demand for ATMEGA328P microcontrollers has shown its popularity! Thus, we’ve compiled a list of alternatives to cater to all your project needs and bypass the supply shortage. It is suitable for projects and autonomous systems where a simple, low-powered, low-cost microcontroller is needed including Industrial control systems, SMPS and Power Regulation systems. ![]() Popularized by the maker movement, ATMEGA328P is found on the pilot Arduino UNO board and many other Atmega microcontrollers support the Arduino platform. The device operates between 1.8-5.5 volts. It has a programmable watchdog timer with internal oscillator, and five software selectable power saving modes. It has 32KB of ISP flash memory with read-while-write capabilities, 1024B EEPROM, 2KB SRAM, 23 general purpose I/O lines, 32 general purpose working registers, three flexible timer/counters with compare modes. – ) What is an ATMEGA328P-AU microcontroller?ĪTMEGA328P-AU is in the family of picoPower® 8-bit AVR® RISC-based microcontrollers by Microchip. The global chip shortage emerged in 2020 and is an ongoing problem where the demand for integrated circuits such as computer chips is greater than supply.(Source: ©Quardia Inc. Hence, in view of the current ATMEGA328P-AU supply shortage and inflated prices, what are the alternatives? Keep reading to find out. Currently, the delivery time for some Microchip devices have been extended to more than 52 weeks. This in part is due to Microchip’s current limited production capacity, resulting in prolonged product delivery. According to a Quiksol report, demand for Microchip MCUs has been strong since January 2022, with popular models such as ATMEGA328P-AU experiencing huge price increases by re-sellers. ![]()
