ATMEGA328PB

ATmega328PB low-power CMOS 8-bit microcontroller

The ATmega328PB is the first 8-bit microcontroller to feature the successful Atmel QTouch® Peripheral Touch Controller (PTC). By executing powerful instructions in a single clock cycle, the ATmega328PB achieves throughputs close to 1MIPS per MHz. This empowers the system designer to optimize the device for power consumption versus processing speed.

The core combines a rich instruction set with 32 general purpose working registers. All the 32 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two independent registers to beaccessed in a single instruction executed in one clock cycle. The resulting architecture is more code efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers.

The ATmega328PB is supported with a full suite of program and system development tools including C compilers, macro assemblers, program debugger/simulators, in-circuit emulators, and evaluation kits.

Note:

ATmega328PB is not a drop-in replacement for ATmega328 variants, but a new device. However, the functions are backward compatible with the existing ATmega328 functions. Existing code for these devices will work in the new devices without changing existing configuration or enabling new functions. The code that is available for your existing ATmega328 variants will continue to work on the new ATmega328PB device.
