The maximum operating frequency of the MC9S12D64CFUE is 25 MHz, but it can be overclocked to 30 MHz with careful consideration of power consumption and thermal management.
The clock settings for the MC9S12D64CFUE can be configured using the Clock Generation Module (CGM) registers. The CGM provides a flexible clocking system that allows the user to select from various clock sources, including the internal oscillator, external oscillator, and PLL.
The MC9S12D64CFUE has 64 KB of flash memory and 8 KB of RAM. The flash memory is divided into two blocks: a 48 KB block for program code and a 16 KB block for data storage.
The MC9S12D64CFUE has a built-in Computer Operating Properly (COP) watchdog timer that can be enabled and configured using the COP control register. The COP timer can be set to timeout after a specified period of inactivity, and can be reset by writing to the COP control register.
The power consumption of the MC9S12D64CFUE varies depending on the operating frequency, voltage, and mode of operation. In active mode, the typical current consumption is around 10 mA at 25 MHz and 3.3 V. In sleep mode, the current consumption is around 10 μA.
