MK22FX512VLK12 datasheet by Freescale Semiconductor

MK22FX512VLK12 Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the MK22FX512VLK12?
  The maximum operating frequency of the MK22FX512VLK12 is 120 MHz.
• How do I configure the clock source for the MK22FX512VLK12?
  The clock source for the MK22FX512VLK12 can be configured using the MCG (Multipurpose Clock Generator) module. The MCG allows the user to select between internal clock sources (e.g. IRC48M, IRC4M) or external clock sources (e.g. crystal oscillator, external clock input). The configuration is done through the MCG_C1, MCG_C2, and MCG_C4 registers.
• What is the maximum amount of flash memory that can be programmed on the MK22FX512VLK12?
  The MK22FX512VLK12 has 512 KB of flash memory, and the entire flash memory can be programmed. However, it's recommended to leave some space for the bootloader and other system requirements.
• How do I implement low-power modes on the MK22FX512VLK12?
  The MK22FX512VLK12 has several low-power modes, including Stop, VLPR, and VLPW. These modes can be entered by configuring the SMC (System Mode Controller) module and using the corresponding APIs. Additionally, the device can be put into a low-power mode by using the WAIT and STOP instructions.
• What is the maximum current consumption of the MK22FX512VLK12?
  The maximum current consumption of the MK22FX512VLK12 depends on the operating frequency, voltage, and peripherals used. According to the datasheet, the maximum current consumption is around 350 mA at 120 MHz and 3.3V.
