ATTINY461-20SUR Product Details

ATTINY461-20SUR Overview


The package has a 20-SOIC (0.295, 7.50mm Width) shape. With 16 I/Os, it's pretty good. The Microcontroller's mounting type is Surface Mount and this IC chip has the following features. As the name implies, this Microcontroller is based on the 8-Bit core. As far as its program memory type is concerned, it is FLASH. Temperatures within -40°C~85°C TA range are measured by this Microcontroller. The AVR® ATtiny series is comprised of this electrical component. The electronic part has a program memory size of 4KB 2K x 16. There's a AVR Core Processor inside. The IC chip fits into the MICROCONTROLLER, RISC uPs/uCs/Peripheral ICs category. There are 20 terminations on the IC chip. 8-bits are the size of the data that comes with MCU. A 5V volt supply is provided by the Microcontroller chip. In addition to that, MCU chip has NO DMA channels. Its memory size is 4kB. It is possible to find alternatives to the base part number ATTINY461 by using the part number search tool. An effective performance can be achieved at a frequency of 20MHz. There are a total of YES channels in the device. It is possible to access the 20 pins on the chip. In total, it has 2 timers and counters in it. There are several CPUs that are embedded in the device, including the the AVR RISC CPU. As an example, there is a feature called ALSO OPERATES AT 2.7 MINIMUM SUPPLY AT 10 MHZ to name only a few.
