ATmega324PB数据手册开发板套件编程器的评估板-嵌入式-MCUDSP规格书PDF

描述 Description

The high-performance Microchip 8-bit AVR® RISC-basedpicoPower® microcontroller combines 32 KB ISP Flash memory with read-while-writecapabilities, 1 KB EEPROM, 2 KB 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 Two-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 features the successful QTouch® PeripheralTouch Controller (PTC). The PTC acquires signals to detecttouch on capacitive sensors and supports both self- andmutual-capacitance sensors. The ATmega324PB 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.The ATmega324PB supports 32buttons in self-capacitance mode or up to 256 buttons inmutual-capacitance mode. Mix-and-match mutual-and self-capacitancesensors are possible. Only one pin is required per electrode, and noexternal components are required, delivering savings on the BOM costcompared to competing solutions.By executing powerfulinstructions in a single clock cycle, the device achieves throughputsapproaching one MIPS per MHz, balancing power consumption and processingspeed.
