ML610400 series/ML610300 series How should I terminate the VDDX, XT0, and XT1 pins when the 32.768 kHz crystal is not connected?

2024-08-30 - Technical Q&A This LSI does not correctly operate if the 32.768 kHz low-speed clock is not supplied. Please be sure to connect the 32.768 kHz crystal oscillator. Related Products: ML610(Q)40x, ML610(Q)42x, ML610(Q)47x, ML610(Q)48x, ML610Q30x, ML610Q35x, ML610Q36x, ML610Q38x, ML610Q41x, ML610Q43x, ML610Q46x, ML620Q416/ML620Q418

What is load capacitance (CL)?

2024-08-30 - Technical Q&A CL stands for Load Capacitance. Load capacitance is defined as being the total capacitance present in the oscillator circuit as measured or calculated from the two terminals of the crystal. The output frequency of the crystal when assembled in an oscillator circuit is a function of CL. In order for the quartz crystal unit to exhibit an output frequency as close to specified as possible, it is important to measure precisely what the actual CL is in the circuit.

What kind of power modes does EVE support?

2024-06-13 - Technical Q&A There are 4 power modes that EVE supports. 1) Active state – EVE is in full function mode preforming graphic rendering, touch processing and audio processing. 2) Standby state – in this state, the crystal oscillator and PLL are functioning, the system clock to EVE’s core is disabled. All register content is retained. 3) Sleep state – in this state, the crystal oscillator and PLL is disabled, the system clock applied to EVE’s core is disabled. All register content is retained. 4) Power down state – in this state, the internal 1.2V regulator supplying the core digital logic is disabled. The crystal oscillator and PLL is disabled, and the system clock applied to EVE’s core is disabled. All register contents are lost and reset to default upon power on reset.
