Add To BomATMEGA328PB-MU General Description
The high-performance, low-power Microchip 8-bit AVR® RISC-based microcontroller combines 64 KB ISP Flash memory with read-while-write capabilities, 2 KB EEPROM, 4 KB SRAM, 27 general purpose I/O lines, 32 general purpose working registers, two flexible timer/counters with compare modes and PWM, one UART with HW LIN, an 11-channel 10-bit A/D converter with two differential programmable gain input stages, a 10-bit D/A converter, a programmable watchdog timer with an internal individual oscillator, SPI serial port, an on-chip debug system, and four software selectable power saving modes. The device operates between 2.7-5.5 volts.
By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching one MIPS per MHz, balancing power consumption and processing speed.
