ATTINY861-20PU Product Details

ATTINY861-20PU Overview


Packaged in a 20-DIP (0.300, 7.62mm) format, this MCU is available in a compact size. There are 16 I/Os on the Microcontroller. It is important to note that the Microcontroller has a Through Hole mounting type. 8-Bit core is the basis for this Microcontroller. This program has a type of memory called FLASH for this MCU's program memory. Temperatures in this range are operated by this Microcontroller. The AVR® ATtiny series includes this electrical component. There is 8KB 4K x 16 bytes of program memory in MCU, which corresponds to the size of the program. With a AVR Core processor, MCU is equipped with the latest technology available. This is a MICROCONTROLLER, RISC uPs/uCs/Peripheral IC. During the manufacturing process, 20 terminations were applied to the IC chip. 8-bits are used in Microcontroller. The MCU chip's supply output is 5V volts. Currently, MCU chip has NO DMA channels. 8kB memory size belongs to the Chip part. Alternatives can be found by looking at the base part number ATTINY861. In the case of 20MHz frequency operation, it can perform efficiently. There are YES PWM channels on the device. The chip has 20 pins. The clock has 2 timers/counters to keep track of the time. 20 pins are counted on this board. This device is embedded with a AVR RISC processor family, which is a powerful and efficient CPU. There is a FLASH memory feature on this equipment. With AVR core architecture, it offers high performance. A total of 16 programmable I/Os are available on this board. As a few examples, there are additional features like ALSO OPERATES AT 2.7 MINIMUM SUPPLY AT 10 MHZ that are available in the software. A total of 11 ADC channels are present in this device. There are 8 bits in total on an IC chip. There are 6 PWM channels that are used by the device. An 1-channel PWM controller is used by the device.
