AT90PWM2/3/2B/3B4.1 Block Diagram Figure 4-1. 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 con- ventional CISC microcontrollers. The AT90PWM2/2B/3/3B provides the following features: 8K bytes of In-System Programmable 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 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. 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 D ir e c t A d d re s s in g In d ir e c t A d d re s s in g Interrupt Unit SPI Unit Watchdog Timer 3 Analog Comparators DAC ADC PSC 2/1/0 Timer 1 Timer 0 DALI USART8 4317KS–AVR–03/2013

AT90PWM2/3/2B/3BThe Idle mode stops the CPU while allowing the SRAM, Timer/Counters, SPI ports and interrupt system to continue functioning. The Power-down mode saves the register contents but freezes the Oscillator, disabling all other chip functions until the next interrupt or Hardware Reset. The ADC Noise Reduction mode stops the CPU and all I/O modules except ADC, to minimize switch- ing noise during ADC conversions. In Standby mode, the Crystal/Resonator Oscillator is running while the rest of the device is sleeping. This allows very fast start-up combined with low power consumption. The device is manufactured using Atmel’s high-density nonvolatile memory technology. The On- chip ISP Flash allows the program memory to be reprogrammed in-system through an SPI serial interface, by a conventional nonvolatile memory programmer, or by an On-chip Boot program running on the AVR core. The boot program can use any interface to download the application program in the application Flash memory. Software in the Boot Flash section will continue to run while the Application Flash section is updated, providing true Read-While-Write operation. By combining an 8-bit RISC CPU with In-System Self-Programmable Flash on a monolithic chip, the Atmel AT90PWM2/3 is a powerful microcontroller that provides a highly flexible and cost effective solution to many embedded control applications. The AT90PWM2/3 AVR is supported with a full suite of program and system development tools including: C compilers, macro assemblers, program debugger/simulators, in-circuit emulators, and evaluation kits. 4.2 Pin Descriptions 4.2.1 VCC Digital supply voltage. 4.2.2 GND Ground. 4.2.3 Port B (PB7..PB0) Port B is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The Port B output buffers have symmetrical drive characteristics with both high sink and source capability. As inputs, Port B pins that are externally pulled low will source current if the pull-up resistors are activated. The Port B pins are tri-stated when a reset condition becomes active, even if the clock is not running. Port B also serves the functions of various special features of the AT90PWM2/2B/3/3B as listed on page 69. 4.2.4 Port C (PC7..PC0) Port C is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The Port C output buffers have symmetrical drive characteristics with both high sink and source capability. As inputs, Port C pins that are externally pulled low will source current if the pull-up resistors are activated. The Port C pins are tri-stated when a reset condition becomes active, even if the clock is not running. Port C is not available on 24 pins package. Port C also serves the functions of special features of the AT90PWM2/2B/3/3B as listed on page 72.9 4317KS–AVR–03/2013
