ATMEGA48A-PU Frequently Asked Questions (FAQ)
-
The maximum clock frequency for the ATMEGA48A-PU is 20 MHz, but it can be overclocked to 24 MHz with some limitations.
-
The ATMEGA48A-PU can be programmed using a variety of methods, including In-System Programming (ISP), High-Voltage Serial Programming (HVSP), and Parallel Programming. You can use a programmer such as the Atmel-ICE or a third-party programmer like the USBasp.
-
The power consumption of the ATMEGA48A-PU depends on the operating frequency, voltage, and mode of operation. In active mode, the typical current consumption is around 10-15 mA at 5V and 10 MHz. In power-down mode, the current consumption is typically around 0.1-1 mA.
-
Yes, the ATMEGA48A-PU can operate with a 3.3V power supply, but the maximum clock frequency is limited to 12 MHz. You should also ensure that the input voltage on the reset pin (RESET) is within the recommended range of 0.2V to 5.5V.
-
The ATMEGA48A-PU can be reset using the reset pin (RESET), which is active low. You can also use the watchdog timer or the Brown-Out Detector (BOD) to reset the device.
