The high-performance Microchip 8-bit AVR® RISC-based picoPower® microcontroller combines 32 KB ISP Flash memory with read-while-write capabilities, 1 KB EEPROM, 2 KB 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 Two-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 to detect touch on capacitive sensors and supports both self- and mutual-capacitance sensors. The ATmega324PB PTC is supported by the Microchip QTouch Composer development tool (QTouch Library project builder and QTouch Analyzer). It provides a faster and less complex capacitive touch implementation in any application.
The ATmega324PB supports 32 buttons in self-capacitance mode or up to 256 buttons in mutual-capacitance mode. Mix-and-match mutual-and self-capacitance sensors are possible. Only one pin is required per electrode, and no external components are required, delivering savings on the BOM cost compared to competing solutions.
By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching one MIPS per MHz, balancing power consumption and processing speed.
