Microchip ATMEGA325-16AU, 8bit AVR Microcontroller, ATmega325, 16MHz, 32 kB Flash, 64-Pin TQFP, Микроконтроллер

The Microchip ATmega325 CMOS 8-bit microcontroller is based on the AVR enhanced RISC architecture. It operates on 4.5V to 5.5V voltage supply. The AVR combines a rich instruction set with 32 general purpose working registers. It features 32Kbytes of In-System Programmable Flash with Read-While-Write capabilities, 1K bytes EEPROM, 2Kbytes SRAM, 54/69 general purpose I/O lines, 32 general purpose working registers, a JTAG interface for Boundary-scan, On-chip Debugging support and programming, three flexible Timer/Counters with compare modes, internal and external interrupts, a serial programmable USART, Universal Serial Interface with Start Condition Detector, an 8-channel, 10-bit ADC, a programmable Watchdog Timer with internal Oscillator, an SPI serial port, and five software selectable power saving modes. The Idle mode stops the CPU while allowing the SRAM, Timer/Counters, SPI port, and interrupt system to continue functioning. The Power-down mode saves the register contents but freezes the Oscillator, disabling all other chip functions until the next interrupt or hardware reset.
