ATMEGA644P-15AT1 Frequently Asked Questions (FAQ)

  • The ATMEGA644P-15AT1 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 power consumption of the ATMEGA644P-15AT1 in sleep mode depends on the sleep mode used. In power-down sleep mode, the device consumes around 0.1 μA, while in power-save sleep mode, it consumes around 1.5 μA. In standby sleep mode, the device consumes around 5 μA.

  • The ATMEGA644P-15AT1 is a commercial-grade device and is not designed for use in harsh environments. It is rated for operation in temperatures ranging from 0°C to 70°C. For use in harsh environments, a more ruggedized device such as the ATMEGA644P-15AU1, which is rated for operation in temperatures ranging from -40°C to 125°C, may be more suitable.

  • The I/O pins of the ATMEGA644P-15AT1 can source or sink up to 40 mA of current. However, it is recommended to limit the current to 20 mA or less to ensure that the device operates within its specifications.

  • The ATMEGA644P-15AT1 is designed to operate at 5V, but it can also be used with a 3.3V power supply. However, the device's performance and functionality may be affected, and some features may not be available. It is recommended to consult the datasheet and application notes for more information on using the device with a 3.3V power supply.
