ATTINY1634-MFR Product Details

ATTINY1634-MFR Overview


In a 20-WFQFN Exposed Pad package, the MCU is available. 18 I/Os are available. The Microcontroller has a mounting type of Surface Mount, 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~125°C TA that is operated by this Microcontroller. AVR® ATtiny series components make up this electrical component. 16KB 16K x 8 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. 20 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. 16kB is the memory size of the part. The base part number ATTINY1634 can be used to find alternatives. The efficiency of this device can be improved when operating at a frequency of 12MHz. The device works in NO PWM channels. Located on the chip are 20 pins. The clock has 2 timers or counters on it. I would like to mention a few additional features such as ALSO OPERATES MIN 1.8 V AT 2 MHZ in order to name a few.
