3.4.6 RTC
Once external power supply is cut off, the chipset itself still with high consumption(around 20uA),
so the OK1052-C is mounted with RTC chip RX8010SJ(U12) to reduce the chip power
consumption for time saving(classic value is 160nA/ 3V)
3.4.7 Audio
The OK1052-C is with one MIC interface(P4), it’s designed as a standard 3.5mm jack(P5), chip
model is WM8960(U1), it can communicate audio data with IIS on SoM, setting by IIC. Pin
SAI2_RXD and JTAG_MOD are multiplexed, make selection by P3 jumper cap, jump P3 to audio
to enable WM8960 MIC function
