ATTINY45-20PU Product Details

ATTINY45-20PU Overview


In a 8-DIP (0.300, 7.62mm) package, the MCU is available. 6 I/Os are available. The Microcontroller has a mounting type of Through Hole, which indicates that it is mounted conveniently. The 8-Bit core is the core of the MCU. There is a FLASH type of memory for its program. There is a temperature range of -40°C~85°C TA that is operated by this Microcontroller. AVR® ATtiny series components make up this electrical component. 4KB 2K x 16 is the size of its program memory. A AVR Core processor is used to power the device. This device falls under the MICROCONTROLLER, RISC uPs/uCs/Peripheral ICs category. 8 is the number of terminations on the IC chip that are present. This part works in a 8-bit manner. There is a 5V volt supply output on the chip. DMA channels number NO. 4kB is the memory size of the part. The base part number ATTINY45 can be used to find alternatives. The efficiency of this device can be improved when operating at a frequency of 20MHz. The device works in YES PWM channels. Located on the chip are 8 pins. The clock has 2 timers or counters on it. In this device, there is a AVR RISC CPU embedded within it. It programs in 6 Programmable I/O. I would like to mention a few additional features such as ALSO OPERATES AT 2.7 V MINIMUM SUPPLY AT 10 MHZ in order to name a few. A total of 4 channels of ADC are available on this device. There are 1 I2C channels included in the part, which has been designed for the purpose. This part contains 6 external interrupts which provide a high level of flexibility.
