ATTINY828-AU Product Details

ATTINY828-AU Overview


Packaged in a 32-TQFP format. A total of 28 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 8KB 8K x 8 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 32 terminations on the IC chip, which means there are 32 terminations on the integrated circuit chip. In addition, MCU chip comes with a 8-bit size. The system has NO channels for DMA communication. There is 8kB memory size assigned to the part. Alternatives can be found by searching through the base part number ATTINY828 to find them. At a frequency of 20MHz, Microcontroller can operate efficiently. This MCU Chip uses YES PWM channels to operate. Chips have 32 pins. There are 2 timers/counters in this device. In total, it has 32 pins. The AVR RISC CPU family is embedded in the device, so it can handle a wide range of operations. The equipment has a FLASH memory that is built in. It is equipped with a AVR core architecture which is integrated into it. It has 8 channels that can be accessed through UART. It consists of 28 channels in total for the ADC. This device uses 4 PWM channels to generate the voltage. 1 channels of I2C have been incorporated into the design of the part.
