ATMEGA644P-15AT Frequently Asked Questions (FAQ)
-
The ATMEGA644P-15AT can operate at a maximum clock frequency of 20 MHz, but it is recommended to use a clock frequency of 16 MHz or lower for optimal performance and to ensure that the device operates within its specifications.
-
The clock source for the ATMEGA644P-15AT can be configured using the CKSEL fuses. The CKSEL fuses determine the clock source, clock frequency, and startup time. The CKSEL fuses can be programmed using a programmer or a boot loader.
-
The power consumption of the ATMEGA644P-15AT depends on the operating frequency, voltage, and mode of operation. In active mode, the typical power consumption is around 15 mA at 5V and 16 MHz. In power-down mode, the typical power consumption is around 0.1 mA at 5V.
-
The ATMEGA644P-15AT can be programmed using a variety of programming interfaces, including ISP (In-System Programming), JTAG, and HVSP (High-Voltage Serial Programming). The device can be programmed using a programmer or a boot loader.
-
The ATMEGA644P-15AT has 64 KB of flash memory, which can be used for programming the device. However, the actual amount of flash memory available for programming may be less due to the bootloader and other system requirements.
