ATTINY1634-SU Product Details

ATTINY1634-SU Overview


Packaged in a 20-SOIC (0.295, 7.50mm Width) format, this MCU is available in a compact size. There are 18 I/Os on the Microcontroller. It is important to note that the Microcontroller has a Surface Mount mounting type. 8-Bit core is the basis for this Microcontroller. This program has a type of memory called FLASH for this MCU's program memory. Temperatures in this range are operated by this Microcontroller. The AVR® ATtiny series includes this electrical component. There is 16KB 16K x 8 bytes of program memory in MCU, which corresponds to the size of the program. With a AVR Core processor, MCU is equipped with the latest technology available. This is a MICROCONTROLLER, RISC uPs/uCs/Peripheral IC. During the manufacturing process, 20 terminations were applied to the IC chip. 8-bits are used in Microcontroller. The MCU chip's supply output is 5V volts. Currently, MCU chip has NO DMA channels. 16kB memory size belongs to the Chip part. Alternatives can be found by looking at the base part number ATTINY1634. In the case of 12MHz frequency operation, it can perform efficiently. There are YES PWM channels on the device. The chip has 20 pins. The clock has 2 timers/counters to keep track of the time. 20 pins are counted on this board. This device is embedded with a AVR RISC processor family, which is a powerful and efficient CPU. As a few examples, there are additional features like IT ALSO OPERATES AT 2.7V AT 8 MHZ AND 1.8 V AT 2MHZ that are available in the software. A total of 12 ADC channels are present in this device. There are 4 PWM channels that are used by the device. An 1-channel PWM controller is used by the device.
