타입 = Flash The Microchip ATmega324PB CMOS 8-bit microcontroller is based on the AVR enhanced RISC architecture. It operates on 1.8V to 5.5V voltage supply. The AVR core combines a rich instruction set with 32 general purpose working registers. It features 32K bytes of In-System Programmable Flash with Read-While-Write capabilities, 1Kbytes EEPROM, 2Kbytes SRAM, 39 general purpose I/O lines, 32 general purpose working registers, five flexible Timer/Counters with compare modes, internal and external interrupts, three serial programmable USART, two byte-oriented 2-wire Serial Interface (I2C), two SPI serial port, a 8-channel 10-bit ADC with optional differential input stage with programmable gain, a programmable Watchdog Timer with internal Oscillator, IEEE std. 1149.1 compliant JTAG test interface, also used for accessing the On-chip debug system and programming, clock failure detection mechanism and six software selectable power saving modes. The Idle mode stops the CPU while allowing the SRAM, Timer/Counters, USART, 2-wire Serial Interface, SPI port, and interrupt system to continue functioning. PTC with enabling up to 32 self-cap and 256 mutual-cap sensors. The Power-down mode saves the register contents but freezes the Oscillator, disabling all other chip functions until the next interrupt or hardware reset.Up to 20 MIPS throughput at 20MHz Programming lock for software security Boundary-scan capabilities according to the JTAG Standard Extensive on-chip debug support Programming of flash, EEPROM, fuses, and lock bits through the JTAG Interface Two 8-bit Timer/Counters with separate prescaler and compare mode Real time counter with separate oscillator Two Master/Slave SPI serial interfaces Programmable watchdog timer with separate on-chip oscillator Power-on Reset and Programmable Brown-out Detection Internal 8 MHz Calibrated Oscillator External and Internal Interrupt Sources Clock Failure detection mechanism and switch to internal 8 MHz RC oscillator in case of Failure Individual serial number to represent a unique ID
