DS87C520-MCL+ Frequently Asked Questions (FAQ)
-
The recommended power-up sequence is to apply VCC first, followed by VDD, and then the clock signal. This ensures proper initialization of the device.
-
The clock source can be configured using the CLK_SEL pin. Tie it to VCC for an internal clock source or to GND for an external clock source. Additionally, the clock frequency can be set using the XTAL1 and XTAL2 pins.
-
The maximum clock frequency supported is 40 MHz. However, it's recommended to operate the device at a frequency below 30 MHz for optimal performance and to minimize power consumption.
-
The watchdog timer can be implemented using the WDT pin. Connect a resistor and capacitor in series between the WDT pin and VCC to set the watchdog timer period. The watchdog timer can be enabled or disabled using the WDT_EN bit in the SYSCFG register.
-
The BOD is used to detect when the supply voltage falls below a certain threshold (typically 2.5V). When this occurs, the device resets to prevent incorrect operation. The BOD can be enabled or disabled using the BOD_EN bit in the SYSCFG register.
