ATTINY841-MMHR Product Details

ATTINY841-MMHR Overview


There is a 20-VFQFN Exposed Pad package available. The board has 12 I/Os. Using the Mounting Type Surface Mount, the MCU is mounted on PCB. A 8-Bit core is used in order to power the IC chip. The type of memory it uses for its program is FLASH. -40°C~85°C TA is the temperature range at which this Microcontroller operates. AVR® ATtiny-series components are electrical components. In the case of this Microcontroller, the memory size of the program is 8KB 8K x 8. Powered by a AVR Core processor. Microcontroller's a MICROCONTROLLER, RISC uPs/uCs/Peripheral IC. IC Chip terminations are 20. As a result, this Microcontroller comes with a 8-bit size. Input voltage for the chip is 3.3V volts. A total of NO DMA channels are available. This IC part has a memory size of 8kB. There are a number of alternatives to the base part number ATTINY841 that you can find. Performing well when operated at frequency 16MHz can be achieved. Using YES PWM channels, the device works. On the chip, there are 20 pins that can be accessed. It comes with 3 timers/counters that can be set up. The device is powered by the the AVR RISC CPU family that is embedded in it. FLASH memory is one of the features of this equipment. The CPU is based on AVR cores. There are 12 Programmable I/Os on this computer. The device has a total of 12 ADC channels in total. There are 1 A/D converters built into the device, which makes it quite versatile. There are 2 PWM channels used by the device in total. A total of 1 I2C channels have been integrated into the part.
