AT32UC3A364-ALUR Product Details

AT32UC3A364-ALUR Overview


There is a 144-LQFP package available. The board has 110 I/Os. Using the Mounting Type Surface Mount, the MCU is mounted on PCB. A 32-Bit core is used in order to power the IC chip. The type of memory it uses for its program is FLASH. -40°C~85°C TA is the temperature range at which this Microcontroller operates. AVR®32 UC3 A3-series components are electrical components. In the case of this Microcontroller, the memory size of the program is 64KB 64K x 8. Powered by a AVR Core processor. Microcontroller's a MICROCONTROLLER, RISC uPs/uCs/Peripheral IC. IC Chip terminations are 144. As a result, this Microcontroller comes with a 32-bit size. Input voltage for the chip is 1.85V volts. A total of YES DMA channels are available. This IC part has a memory size of 64kB. There are a number of alternatives to the base part number AT32UC3A364 that you can find. Performing well when operated at frequency 66MHz can be achieved. Using NO PWM channels, the device works. On the chip, there are 144 pins that can be accessed. It comes with 3 timers/counters that can be set up. The device is powered by the the AVR RISC CPU family that is embedded in it. FLASH, SRAM memory is one of the features of this equipment. There are 23 Programmable I/Os on this computer. In addition to these features, there are a number of other ones, such as this one: IT ALSO OPERATES AT 3.3 V.
