ATMEGA644PA-MUR Frequently Asked Questions (FAQ)
-
The maximum clock frequency for the ATMEGA644PA-MUR is 20 MHz, but it can be overclocked to 24 MHz with some limitations.
-
The clock source can be configured using the CKSEL fuses. The CKSEL0-CKSEL3 fuses determine the clock source, and the SUT0-SUT1 fuses determine the start-up time.
-
The power consumption of the ATMEGA644PA-MUR depends on the operating frequency, voltage, and mode. In active mode, the typical power consumption is around 15mA at 5V and 20MHz. In power-down mode, the typical power consumption is around 0.1mA.
-
The ATMEGA644PA-MUR can be programmed using a variety of methods, including ISP (In-System Programming), HVSP (High-Voltage Serial Programming), and JTAG. The most common method is ISP using a programmer such as the AVRISP or the Arduino ISP.
-
The main difference is that the ATMEGA644PA-MUR is a Pb-free (lead-free) version of the ATMEGA644P-MUR, which contains lead. The Pb-free version is more environmentally friendly and compliant with RoHS (Restriction of Hazardous Substances) regulations.
