MAX32664GTGC+ - Analog Devices

MAX32664GTGC+ Frequently Asked Questions (FAQs)

• What is the recommended crystal oscillator frequency for the MAX32664GTGC+?
  The recommended crystal oscillator frequency for the MAX32664GTGC+ is 32.768 kHz, which is used as the clock source for the real-time clock (RTC) and other peripherals.
• How do I configure the MAX32664GTGC+ for low-power operation?
  To configure the MAX32664GTGC+ for low-power operation, you can use the Power Mode Controller (PMC) to select the desired power mode, such as Sleep or Deep Sleep. You can also use the Clock Controller (CLKC) to gate clocks to peripherals when not in use, and adjust the voltage regulator (VREG) to reduce power consumption.
• What is the maximum current that can be sourced or sunk by the GPIO pins?
  The maximum current that can be sourced or sunk by the GPIO pins of the MAX32664GTGC+ is 4 mA per pin, with a total current limit of 100 mA for all GPIO pins combined.
• How do I use the analog-to-digital converter (ADC) on the MAX32664GTGC+?
  The ADC on the MAX32664GTGC+ is a 12-bit, 1Msps converter that can be used to convert analog signals from external sensors or other sources. To use the ADC, you need to configure the ADC clock, select the input channel, and set the conversion mode. You can then read the converted digital value from the ADC result register.
• Can I use the MAX32664GTGC+ with an external memory?
  Yes, the MAX32664GTGC+ has an external memory interface that allows you to connect external flash memory or SRAM devices. The interface supports various memory types, including SPI, QSPI, and SDRAM, and can be configured using the External Memory Controller (EMC).
