AT32UC3A4128S-C1UT Product Details

AT32UC3A4128S-C1UT Overview


Packaged in a 100-VFBGA format. A total of 88 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 A4 series electrical component is used in this application. This program has a program memory of 128KB 128K 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 1.85V volts. The system has YES channels for DMA communication. There is 128kB memory size assigned to the part. Alternatives can be found by searching through the base part number AT32UC3A4128 to find them. At a frequency of 66MHz, Microcontroller can operate efficiently. This MCU Chip uses NO PWM channels to operate. Chips have 100 pins. There are 3 timers/counters in this device. In total, it has 100 pins. The AVR RISC CPU family is embedded in the device, so it can handle a wide range of operations. It is equipped with a AVR core architecture which is integrated into it. As an example, one of the additional features that you can use is IT ALSO OPERATES AT 3.3 V.
