ATTINY261A-SUR Product Details

ATTINY261A-SUR Overview


The package is 20-SOIC (0.295, 7.50mm Width)-shaped. There are 16 I/Os. In the case of the IC chip, the type of mounting is Surface Mount. Microcontroller is based on the 8-Bit core architecture. The type of program memory it uses is FLASH. Temperatures in the range of -40°C~85°C TA are operated by this Microcontroller. It is part of the AVR® ATtiny series of electrical components. Having a size of 2KB 1K x 16, Microcontroller has a program memory of X bytes. A AVR Core Processor is at the core of this Microcontroller. This device belongs to the MICROCONTROLLER, RISC uPs/uCs/Peripheral ICs category. IC Chip 20 has 20 terminations. 8-bits are used for its size. IC Chip has 5V volt supply outputs. With NO DMA channels, Microcontroller chip can handle large data transfers. 2kB is the size of the memory in the IC part. Using the base part number ATTINY261A, you will be able to find alternatives for the part. Using a 20MHz frequency, this electronic part can perform efficiently. Devices work in YES PWM channels. On the chip, 20 pins are accessible. In total, there are 2 timers/counters on the device. There is an embedded the AVR RISC CPU family inside the device, which makes it a powerful device. In addition to the above, there are other features such as ALSO OPERATES AT 1.8V MINIMUM SUPPLY AT 4 MHZ; AND 2.7V MINIMUM SUPPLY AT 10 MHZ, to name but a few. The ADC channel count on this device totals up to 11 Channel channels.
