ATTINY24-20MU Product Details

ATTINY24-20MU Overview


The package has a 20-WFQFN Exposed Pad shape. With 12 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 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 2kB. It is possible to find alternatives to the base part number ATTINY24 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 Timer timers and counters in it. A total of 20 pins are included in the package. There are several CPUs that are embedded in the device, including the the AVR RISC CPU. As an example, there is a feature called OPERATES AT 2.7 V MINIMUM SUPPLY AT 10 MHZ to name only a few. The ADC channels on this device total 8 in number. A total of 2 PWM channels are being used by the device. The part has been designed to incorporate 1 I2C channels.
