The high-performance Atmel picoPower 8-bit AVR RISC-based microcontroller combines 32kB ISP flash memory with read-while-write capabilities, 1kB EEPROM, 2kB SRAM, 39 general purpose I/O lines, 32 general purpose working registers, five flexible timer/counters with compare modes, internal and external interrupts, three USARTs with wake-up on start of transmission, two byte-oriented 2-wire serial interface, two SPI serial ports, one 8-channel 10-bit ADC with optional differential input stage with programmable gain, programmable watchdog timer with internal oscillator, 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 1.8-5.5 volts.

The ATmega324PB features the successful QTouch Peripheral Touch Controller (PTC). The PTC acquires signals in order to detect touch on capacitive sensors, and supports both self- and mutual-capacitance sensors. The ATmega324PB PTC is supported by the Atmel QTouch Composer development tool (QTouch Library project builder and QTouch Analyzer). It provides a faster and less complex capacitive touch implementation in any application.

It supports 32 buttons in self-capacitance mode, or up to 256 buttons in mutual-capacitance mode. Mix-and-match mutual-and self-capacitance sensors is possible, and only one pin is required per electrode – no external components are required, giving savings on the BOM cost compared to competing solutions.

By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processing speed.
