ATTINY28L-4AU Product Details

ATTINY28L-4AU Overview


The package has a 32-TQFP shape. With 11 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 2KB 1K x 16. There's a AVR Core Processor inside. The IC chip fits into the MICROCONTROLLER, RISC uPs/uCs/Peripheral ICs category. There are 32 terminations on the IC chip. 8-bits are the size of the data that comes with MCU. A 3V volt supply is provided by the Microcontroller chip. In addition to that, MCU chip has NO DMA channels. Its memory size is 2kB. It is possible to find alternatives to the base part number ATTINY28 by using the part number search tool. An effective performance can be achieved at a frequency of 4MHz. There are a total of NO channels in the device. It is possible to access the 32 pins on the chip. In total, it has 1 timers and counters in it. There are several CPUs that are embedded in the device, including the the AVR RISC CPU.
