ATTINY44-20PU Product Details

ATTINY44-20PU Overview


The package is in 14-DIP (0.300, 7.62mm) format. The MCU has 12 I/O ports. There is a mounting type Through Hole associated with this Microcontroller. This Microcontroller is based on the 8-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® ATtiny series of components. Microcontroller has abundant program memory size of 4KB 2K x 16. 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 14 of terminations. A 8-bit operation is performed by this part. There is an output of 5V volts from the Microcontroller chip. A total of NO DMA channels are available on MCU chip. This MCU is implemented with 4kB memory. ATTINY44 serves as a base part number to find alternatives. It exhibits good efficiency when it operates at a frequency of 20MHz 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 14 pins on the chip through the 14 pins. It is equipped with 2 Timer timers and counters. It consists of 14 pins. 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. In addition, there are several other features that can be found in the software, including OPERATES AT 2.7 V MINIMUM SUPPLY AT 10 MHZ. The device features 8 UART channels. There are a total of 8 channels for the ADC on this board, so it has a total of 8 channels. An entire chip has 8 bits. An 2-channel PWM controller is used by the device. In this device, there's an 1-channel PWM controller.
