The recommended operating temperature range for the MC9328MX21CVM is -40°C to 105°C, with a maximum junction temperature of 125°C.
The clock settings for the MC9328MX21CVM can be configured using the Clock Management Unit (CMU) registers. The CMU provides a flexible clocking scheme that allows the user to select from various clock sources, including the internal oscillator, external crystal oscillator, and PLL. The clock settings can be configured using the CMU registers, which are described in the MC9328MX21CVM reference manual.
The maximum frequency of the CPU in the MC9328MX21CVM is 266 MHz, while the maximum frequency of the peripherals is 133 MHz.
The MC9328MX21CVM provides several power management features, including dynamic voltage and frequency scaling, clock gating, and power gating. These features can be implemented using the Power Management Controller (PMC) registers. The PMC provides a flexible power management scheme that allows the user to control the power consumption of the device based on the system requirements.
The MC9328MX21CVM has a 32-bit address bus that can address up to 4 GB of memory. However, the maximum amount of memory that can be connected to the device is limited by the memory technology and the board design. Typically, the maximum amount of memory that can be connected to the MC9328MX21CVM is 1 GB or 2 GB, depending on the memory configuration.
