ATMEGA 1284PU 1452
ATMEGA 1284PU 1452 is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture.
By executing powerful instructions in a single clock cycle, the ATmega1284 achieves throughputs close to 1MIPS per MHz.
This empowers system designer to optimize the device for power consumption versus processing speed.
This blog will introduce ATmega1284 systematically from its features, pinout to its specifications, applications, also including ATMEGA1284 VS ATmega1284P and so much more.
Arduino Library Compatibility
The UNO*Pro is compatible with most of the standard (and third party) Arduino Libraries. However, some of the libraries have small sections of code for specific chips (e.g. ATmega328, ATmega2560 etc).
As the ATmega1284 is not used on any standard Arduino boards these code sections are missing. It is easy enough to modify the libraries for the UNO*Pro, and here are the libraries known to be affected.
The Atmel® ATmega1284 is a low-power CMOS 8-bit microcontroller based on the AVR® enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATmega1284 achieves throughputs close to 1MIPS per MHz.
