AT32UC3A1256-AUR Product Details

AT32UC3A1256-AUR Overview


Packaged in a 100-TQFP format. A total of 69 I/Os are on the Microcontroller. Surface Mount is the mounting type of the Microcontroller that is attached to the panel. This Microcontroller is based on a core called 32-Bit. The type of its program memory is FLASH. In this Microcontroller, temperature is controlled within the range -40°C~85°C TA. A AVR®32 UC3 A1 series electrical component is used in this application. This program has a program memory of 256KB 256K x 8 bytes, which is the size of the program. With a AVR Core Processor, Microcontroller is fast and efficient. ICs for MICROCONTROLLER, RISC uPs/uCs/peripheral parts. There are 100 terminations on the IC chip, which means there are 100 terminations on the integrated circuit chip. In addition, MCU chip comes with a 32-bit size. Microcontroller chip has outputs of 1.8V volts. The system has YES channels for DMA communication. There is 256kB memory size assigned to the part. Alternatives can be found by searching through the base part number AT32UC3A1256 to find them. At a frequency of 66MHz, Microcontroller can operate efficiently. This MCU Chip uses YES PWM channels to operate. Chips have 100 pins. There are 3 timers/counters in this device. The AVR RISC CPU family is embedded in the device, so it can handle a wide range of operations. As an example, one of the additional features that you can use is IT ALSO OPERATES AT 3.3 V. It consists of 8 Channel channels in total for the ADC.
