ATUC256L3U-AUR Product Details

ATUC256L3U-AUR Overview


The package is in 64-TQFP Exposed Pad format. The MCU has 51 I/O ports. There is a mounting type Surface Mount associated with this Microcontroller. This Microcontroller is based on the 32-Bit core. There is a memory type of FLASH in its program memory. The temperature range that this Microcontroller operates at is -40°C~85°C TA. The electrical component that you are looking at belongs to the AVR®32 UC3 L series of components. Microcontroller has abundant program memory size of 256KB 256K x 8. The AVR Core Processor powers the device and is one of its key features. This Microcontroller belongs to the MICROCONTROLLER, RISC uPs/uCs/peripheral ICs type. During the manufacture of the IC chip, there is a number 64 of terminations. A 32-bit operation is performed by this part. There is an output of 1.8V volts from the Microcontroller chip. A total of YES DMA channels are available on MCU chip. This MCU is implemented with 256kB memory. ATUC256L serves as a base part number to find alternatives. It exhibits good efficiency when it operates at a frequency of 50MHz and it is able to operate at a high frequency. It is possible for the device to work with the motor using the PWM channel YES. It is possible to access the 64 pins on the chip through the 64 pins. It is equipped with 7 timers and counters. As far as the CPU is concerned, it is embedded with the the AVR RISC family of processors. There's an integrated FLASH memory in the equipment. There is a AVR core architecture integrated into it. Among the eight programmable I/O sections, there are many different ways in which it can be programmed.
