Block Diagram
Figure 2-1.
The AVR core combines a rich instruction set with 32 general purpose working registers. All the
32 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two independent
registers to be accessed in one single instruction executed in one clock cycle. The resulting
architecture is more code efficient while achieving throughputs up to ten times faster than con-
ventional CISC microcontrollers.
The ATmega16/32/64/M1/C1 provides the following features: 16K/32K/64K bytes of In-System
Programmable Flash with Read-While-Write capabilities, 512/1024/2048 bytes EEPROM,
1024/2048/4096 bytes SRAM, 27 general purpose I/O lines, 32 general purpose working regis-
ters, one Motor Power Stage Controller, two flexible Timer/Counters with compare modes and
PWM, one UART with HW LIN, an 11-channel 10-bit ADC with two differential input stages with
programmable gain, a 10-bit DAC, a programmable Watchdog Timer with Internal Individual
Oscillator, an SPI serial port, an On-chip Debug system and four software selectable power sav-
ing modes.
