Making your own Arduino Uno-compatible projects or need a great value 8-bit surface-mount AVR microcontroller? Then order the Microchip ATmega328P-AU TQFP32 Microcontroller. This is the micrcontroller user in Arduino-compatible boards with the surface-mount chip (such as the Pro Minis). The ATMEGA328-AU is a high-performance 8-bit AVR RISC-based Microcontroller combines 32kb ISP flash memory with read-while-write capabilities, 1kb EEPROM, 23 general purpose I/O lines, 32 general purpose working registers, three flexible timer/counters with compare modes, internal and external interrupts, serial programmable USART, a byte-oriented 2-wire serial interface, SPI serial port, 6-channel 10-bit A/D converter (8 channels in TQFP and QFN/MLF packages), programmable watchdog timer with internal oscillator and five software selectable power saving modes. The device operates between 1.8 to 5.5V. By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processing speed. High-performance, Low-power AVR® 8-Bit Microcontroller Advanced RISC Architecture High Endurance Non-volatile Memory Segments Atmel® QTouch® Library Support Power-on Reset and Programmable Brown-out Detection Internal Calibrated Oscillator External and Internal Interrupt Sources Idle, ADC Noise Reduction, Power-save, Power-down, Standby and Extended Standby Sleep Modes 0 to 20MHz at 4.5 to 5.5V Speed Grade 0.2mA Active mode, 0.1µA Power-down mode, 0.75µA (32kHz RTC) Power-save mode power consumption Visit the Microchip website for data sheets and more information.
