ATMEGA324P-20AU

ATMEL  ATMEGA324P-20AU  微控制器, 8位, 低功率高性能, ATmega, 20 MHz, 32 KB, 2 KB, 44 引脚, TQFP

The is a 8-bit high-performance picoPower AVR RISC-based Microcontroller combines 32kB ISP flash memory with read-while-write capabilities, 1kB EEPROM, 2kB SRAM, 32 general purpose I/O lines, 32 general purpose working registers, real time counter, three flexible timer/counters with compare modes and PWM, 2 USARTs, byte oriented 2-wire serial interface, 8-channel/10-bit A/D converter with optional differential input stage with programmable gain, programmable watchdog timer with internal oscillator, SPI serial port, JTAG IEEE 1149.1 compliant interface for on-chip debugging and programming and six software selectable power saving modes. The device operates between 2.7 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 processor speed.
