8 / 365 page  8 AT90PWM2/3 4317B–AVR–02/05 Overview The AT90PWM2/3 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 AT90PWM2/3 achieves throughputs approaching 1 MIPS per MHz allowing the sys- tem designer to optimize power consumption versus processing speed. Block Diagram Figure 4. Block Diagram 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 conventional CISC microcontrollers. The AT90PWM2/3 provides the following features: 8K bytes of In-System Programma- ble Flash with Read-While-Write capabilities, 512 bytes EEPROM, 512 bytes SRAM, 53 general purpose I/O lines, 32 general purpose working registers,three Power Stage Controllers, two flexible Timer/Counters with compare modes and PWM, one USART 8Kx8 Flash Program Memory Instruction Register Instruction Decoder Program Counter Control Lines 32 x 8 General Purpose Registrers ALU Status and Control I/O Lines EEPROM 512 bytes Data Bus 8-bit Data SRAM 512 bytes Interrupt Unit SPI Unit Watchdog Timer 3 Analog Comparators DAC ADC PSC 2/1/0 Timer 1 Timer 0 DALI USART |
