Microchip AT90PWM316-16MU, 8bit AVR Microcontroller, Microcontrollers, 20MHz, 8 kB Flash, 32-Pin VQFN

The Microchip AT90PWM316 8-bit microcontroller is based on the AVR enhanced RISC architecture. It operates on 2.7V to 5.5V power supply. 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. It features 16K bytes of In-System Programmable Flash with ReadWhile-Write capabilities, 512 bytes EEPROM, 1024 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. The 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 switching noise during ADC conversions. In Standby mode, the Crystal/Resonator Oscillator is running while the rest of the device is sleeping.On-chip 2-cycle Multiplier 16K Bytes Flash of In-System Programmable Program Memory In-System Programming by On-chip Boot Program 512 Bytes of In-System Programmable EEPROM Programming Lock for Flash Program and EEPROM Data Security Non Overlapping Inverted PWM Output Pins With Flexible Dead-Time One 8-bit General purpose Timer/Counter with Separate Prescaler and Capture Mode One 16-bit General purpose Timer/Counter with Separate Prescaler, Compare Mode and Capture Mode Programmable Watchdog Timer with Separate On-Chip Oscillator On-chip PLL for fast PWM (32 MHz, 64 MHz) and CPU (16 MHz)
