Product Information
Product Overview
The ATMEGA324PA-MU is a 8-bit low-power high-performance CMOS Microcontroller based on the AVR enhanced RISC architecture. The 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, a real time counter, three flexible timer/counters with compare modes and PWM, two USARTs, a byte oriented 2-wire serial interface, an 8-channel 10-bit A/D converter with optional differential input stage with programmable gain, programmable watchdog timer with internal oscillator, SPI serial port, a JTAG (IEEE 1149.1 compliant) test interface for on-chip debugging and programming and six 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.
- Advanced RISC architecture, fully static operation and up to 20MIPS throughput at 20MHz
- High endurance non-volatile memory segments - Programming lock for software security
- QTouch® library support capacitive touch buttons, sliders and wheels, up to 64 sense channels
- JTAG (IEEE std. 1149.1 compliant) interface - Extensive on-chip debug support
- Two 8-bit timer/counters with separate prescalers and compare modes
- Real time counter with separate oscillator
- Byte-oriented two-wire serial interface
- Two programmable serial USART
- Serial peripheral interface (SPI)
- Programmable watchdog timer with separate on-chip oscillator
- Power-on reset and programmable brown-out detection
- Internal calibrated RC oscillator
- External and internal interrupt sources
