ATMEGA324PB-ANR Product Details
The high-performance Microchip picoPower 8-bit AVR RISC-basedmicrocontroller combines 32kB ISP flash memory with read-while-writecapabilities, 1kB EEPROM, 2kB SRAM, 39 general purpose I/O lines, 32general purpose working registers, five flexible timer/counters withcompare modes, internal and external interrupts, three USARTs withwake-up on start of transmission, two byte-oriented 2-wire serialinterface, two SPI serial ports, one 8-channel 10-bit ADC with optionaldifferential input stage with programmable gain, programmable watchdogtimer with internal oscillator, a JTAG (IEEE 1149.1 compliant) testinterface for on-chip debugging and programming, and six softwareselectable power saving modes. The device operates between 1.8-5.5volts.
The ATMEGA324PB-ANR features the successful QTouch PeripheralTouch Controller (PTC). The PTC acquires signals in order to detecttouch on capacitive sensors, and supports both self- andmutual-capacitance sensors. The ATMEGA324PB-ANR PTC is supported by theMicrochip QTouch Composer development tool (QTouch Library projectbuilder and QTouch Analyzer). It provides a faster and less complexcapacitive touch implementation in any application.
It supports 32buttons in self-capacitance mode, or up to 256 buttons inmutual-capacitance mode. Mix-and-match mutual-and self-capacitancesensors is possible, and only one pin is required per electrode noexternal components are required, giving savings on the BOM costcompared to competing solutions.
By executing powerfulinstructions in a single clock cycle, the device achieves throughputsapproaching 1 MIPS per MHz, balancing power consumption and processingspeed.
