Product Details
ATMEGA32U4-AU Overview
The package is 44-TQFP-shaped. The board has 26 I/Os. The Microcontroller’s mounting type is Surface Mount and this IC chip has the following features. 8-Bit core is the basis for this Microcontroller. There is a FLASH type of memory for its program. The Microcontroller runs in -40°C~85°C TA Operating Temperature. An electrical component of this type belongs to the AVR® ATmega series. Microcontroller has abundant program memory size of 32KB 16K x 16. A AVR Core processor is used to power the device. The device belongs to MICROCONTROLLER, RISC uPs/uCs/Peripheral ICs Type. During the manufacturing process, 44 terminations were applied to the IC chip. This part works in a 8-bit manner. There is a 5V volt supply output on the chip. MCU chip has NO DMA channels. The part owns 32kB memory size. It is possible to find alternatives to the base part number ATMEGA32U4 Microcontroller by using the part number search tool. Performing well when operated at frequency 16MHz can be achieved. In this chip, 44 pins can be accessed. The clock has 5 timers/counters to keep track of the time. The ADC channel count on this device totals up to 12 channels. 8 PWM channels are used by the device. 1 I2C channels are integrated by the part.
