ATmega16 The ATmega ATmega16 is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATmega16 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed. Pinout: Pinout of ATmega16 1 PB0(XCK/T0) Pin 0 of PORTB T0( Timer0 External Counter Input) XCK ( USART External Clock I/O) 2 PB1(T1) Pin 1 of PORTB T1(Timer1 External Counter Input) 3 PB2(INT2/AIN0) Pin 2 of PORTB AIN0(Internal Analog Comparator Positive Input) INT2( External Interrupt 2 Input) 4 PB3(OC0/AIN1) Pin 3 of PORTB AIN1(Internal Analog Comparator Negative Input) OC0 (Timer0 Output Compare Match Output) or PWM output 5 PB4(SS ) Pin 4 of PORTB SS (SPI Slave Select Input). This pin is low when controller acts as slave. [Serial Peripheral Interface (SPI) for programming] 6 PB5(MOSI) Pin 5 of PORTB MOSI (Master Output Slave Input). When controller acts as slave, the data is received by this pin. [Serial Peripheral Interface (SPI) for programming] 7 PB6(MISO) Pin 6 of PORTB MISO (Master Input Slave Output). When controller acts as slave, the data is sent to master through this pin. [Serial Peripheral Interface (SPI) for programming] 8 PB7(SCK) Pin 7 of PORTB SCK (SPI Bus Serial Clock). This is the clock shared between this controller and other system for accurate data transfer.
