Product Overview
ATMEGA328PB-MNR is a low-power CMOS 8-bit microcontroller based on the AVR-enhanced RISC architecture. By executing powerful instructions in a single clock cycle, it 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 32 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two independent registers to be accessed in a single instruction executed in one clock cycle. The resulting architecture is more code efficient while achieving throughputs upto ten times faster than conventional CISC microcontrollers. The device is manufactured using high-density non-volatile memory technology. It is a powerful microcontroller that provides a highly flexible and cost-effective solution to many embedded control applications.
- Power supply range from 1.8V to 5.5V, high endurance non-volatile memory segments
- Programmable watchdog timer with separate on-chip oscillator, on-chip analogue comparator
- Power-on reset and programmable brown-out detection, internal 8MHz calibrated oscillator
- Clock failure detection mechanism and switch to internal 8MHz RC oscillator in case of failure
- Clock frequency is 1000KHz maximum, conversion time is 200μs maximum
- Gain error is 2LSB typical at (VREF = 4V, VCC = 4V, clkADC = 200KHz)
- Input bandwidth is 38.5MHz typical, analogue input resistance is 100Mohm typical
- Programming enable current is 250μA max at (VCC = 5V ±10%)
- Integral non-linearity is 0.5LSB typ at (VREF = 4V, VCC = 4V, clkADC = 200KHz)
- Operating industrial temperature range from -40°C to 105°C, 32-pad VQFN package
