Figure 4-1.
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 AT90PWM216/316 provides the following features: 16K bytes of In-System Programmable
Flash with Read-While-Write capabilities, 512 bytes EEPROM, 1024 bytes SRAM, 53 general
purpose I/O lines, 32 general purpose working registers,three Power Stage Controllers, two flex-
ible Timer/Counters with compare modes and PWM, one USART with DALI mode, an 11-
channel 10-bit ADC with two differential input stage with programmable gain, a 10-bit DAC, a
programmable Watchdog Timer with Internal Oscillator, an SPI serial port, an On-chip Debug
system and four software selectable power saving modes.
