ATTINY84A-MU Product Details

ATTINY84A-MU Overview


In a 20-WFQFN Exposed Pad package, the MCU is available. 12 I/Os are available. The Microcontroller has a mounting type of Surface Mount, which indicates that it is mounted conveniently. The 8-Bit core is the core of the MCU. There is a FLASH type of memory for its program. There is a temperature range of -40°C~85°C TA that is operated by this Microcontroller. AVR® ATtiny series components make up this electrical component. 8KB 4K x 16 is the size of its program memory. A AVR Core processor is used to power the device. This device falls under the MICROCONTROLLER, RISC uPs/uCs/Peripheral ICs category. 20 is the number of terminations on the IC chip that are present. This part works in a 8-bit manner. There is a 5V volt supply output on the chip. DMA channels number NO. 8kB is the memory size of the part. The base part number ATTINY84A can be used to find alternatives. The efficiency of this device can be improved when operating at a frequency of 20MHz. The device works in YES PWM channels. Located on the chip are 20 pins. The clock has 2 timers or counters on it. In this device, there is a AVR RISC CPU embedded within it. It has built-in FLASH memory. There is an integrated AVR core architecture in it. It programs in 12 Programmable I/O. I would like to mention a few additional features such as ALSO OPERATES 1.8 V MINIMUM SUPPLY AT 4 MHZ in order to name a few. A total of 8 channels of ADC are available on this device. The device uses 2 PWM channels. There are 1 I2C channels included in the part, which has been designed for the purpose.
