MK22FX512VLH12 datasheet by Freescale Semiconductor

MK22FX512VLH12 Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the MK22FX512VLH12?
  The maximum operating frequency of the MK22FX512VLH12 is 120 MHz.
• How do I configure the clock source for the MK22FX512VLH12?
  The clock source for the MK22FX512VLH12 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). 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 MK22FX512VLH12?
  The MK22FX512VLH12 has 512 KB of flash memory, and the maximum amount of flash memory that can be programmed is 510 KB (due to 2 KB reserved for the bootloader).
• How do I implement low-power modes on the MK22FX512VLH12?
  The MK22FX512VLH12 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 ARM Cortex-M4 processor's sleep modes. The low-power modes can be used to reduce power consumption and extend battery life in battery-powered applications.
• What is the maximum current consumption of the MK22FX512VLH12?
  The maximum current consumption of the MK22FX512VLH12 depends on the operating frequency, voltage, and peripherals used. According to the datasheet, the maximum current consumption is approximately 350 mA at 120 MHz and 3.3V.
