32 / 109 page  Package pinouts and signal description STA1295, STA1275 32/109 DS12586 Rev 5 M3_PWREN — V22 O VIO_AON PMU Power Enable. Used by the PMU to enable external voltage regulator, when moving out of Standby state. M3_VDDOK — U22 I VIO_AON PMU VDDOK. This signal is used by the PMU to detect if the external power is valid. The PMU moves to Normal state if VDDOK = 1. SYS_MXTALI — P20 I VIO Crystal input. 24/26 MHz crystal. SYS_MXTALO — N20 O VIO Crystal output. M3_XTALI — D17 I VIO_AON Crystal input. 32 kHz RTC clock. M3_XTALO — D18 O VIO_AON Crystal output. SYS_SYSRES — AC21 I VIO System reset active low. OTP_FUSE_HV — F5 P VIO OTP programming voltage. Leave it floating in the application. Table 17. Analog audio signals Name GPIOs BALLs DIR Power domain Description ADC0_AIN1_L — J22 I ADC0_AVDD ADC0 (Audio). Analog input 1 left channel. ADC0_AIN1_R — K22 I ADC0_AVDD ADC0 (Audio). Analog input 1 right channel. ADC0_AIN2_L — J21 I ADC0_AVDD ADC0 Audio). Analog input 2 left channel. ADC0_AIN2_R — L20 I ADC0_AVDD ADC0 (Audio). Analog input 2 right channel. ADC1_AIN1_N — K23 I ADC1_AVDD ADC1 (Voice). Analog auxiliary differential input 1 negative. ADC1_AIN1_P — J23 I ADC1_AVDD ADC1 (Voice). Analog auxiliary differential input 1 positive. ADC1_MICIN_N — H23 I ADC1_AVDD ADC1 (Voice). Analog MIC differential input negative. ADC1_MICIN_P — H22 I ADC1_AVDD ADC1 (Voice). Analog MIC differential input positive. DAC_OUT0L — G23 O DAC I/OAVDD DAC0. Analog output Channel 0 left. DAC_OUT0R — G22 O DAC I/OAVDD DAC0. Analog output channel 0 right. DAC_OUT1L — H21 O DAC I/OAVDD DAC1. Analog output channel 1 left. DAC_OUT1R — J20 O DAC I/OAVDD DAC1. Analog output channel 1 right. DAC_OUT2L — F22 O DAC I/OAVDD DAC2. Analog output channel 2 left. DAC_OUT2R — F23 O DAC I/OAVDD DAC2. Analog output channel 2 right.
