ATTINY261A-XU Product Details

ATTINY261A-XU Overview


There is a 20-TSSOP (0.173, 4.40mm Width) package available. The board has 16 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 2KB 1K x 16. 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 5V volts. A total of NO DMA channels are available. This IC part has a memory size of 2kB. There are a number of alternatives to the base part number ATTINY261A that you can find. Performing well when operated at frequency 20MHz can be achieved. Using YES PWM channels, the device works. On the chip, there are 20 pins that can be accessed. It comes with 2 timers/counters that can be set up. The pins counted are 20. The device is powered by the the AVR RISC CPU family that is embedded in it. In addition to these features, there are a number of other ones, such as this one: ALSO OPERATES AT 1.8V MINIMUM SUPPLY AT 4 MHZ; AND 2.7V MINIMUM SUPPLY AT 10 MHZ. The device has a total of 11 ADC channels in total. There are 6 PWM channels used by the device in total. A total of 1 I2C channels have been integrated into the part.
