ATTINY44-20SSU Product Details

ATTINY44-20SSU Overview


Packaged in a 14-SOIC (0.154, 3.90mm Width) format. A total of 12 I/Os are on the Microcontroller. Surface Mount is the mounting type of the Microcontroller that is attached to the panel. This Microcontroller is based on a core called 8-Bit. The type of its program memory is FLASH. In this Microcontroller, temperature is controlled within the range -40°C~85°C TA. A AVR® ATtiny series electrical component is used in this application. This program has a program memory of 4KB 2K x 16 bytes, which is the size of the program. With a AVR Core Processor, Microcontroller is fast and efficient. ICs for MICROCONTROLLER, RISC uPs/uCs/peripheral parts. There are 14 terminations on the IC chip, which means there are 14 terminations on the integrated circuit chip. In addition, MCU chip comes with a 8-bit size. Microcontroller chip has outputs of 5V volts. The system has NO channels for DMA communication. There is 4kB memory size assigned to the part. Alternatives can be found by searching through the base part number ATTINY44 to find them. At a frequency of 20MHz, Microcontroller can operate efficiently. Chips have 14 pins. There are 2 Timer timers/counters in this device. In total, it has 14 pins. The equipment has a FLASH memory that is built in. It is equipped with a AVR core architecture which is integrated into it. In the 12 Programmable I/O section, it can be programmed in many different ways. It has 8 channels that can be accessed through UART. It consists of 8 channels in total for the ADC. An integrated circuit with 8 bits has a total of 8 bits. This device uses 2 PWM channels to generate the voltage. 1 channels of I2C have been incorporated into the design of the part.
