21 / 374 page  DA14531 Ultra Low Power Bluetooth 5.1 SoC Final Datasheet Revision 3.1 09-Jul-2020 CFR0011-120-00 21 of 374 © 2020 Dialog Semiconductor Table 1: DA14531 WLCSP17 Ball Description Ball no. Pin Name Type Reset State Description General Purpose I/Os (Note 3) F4 P0_0 DIO (Type B) I-PD INPUT/OUTPUT with selectable pull up/down resistors. Pull-down enabled during and after reset. General purpose I/O port bit or alternate function nodes. Contains state retention mechanism during power- down. RST DIO (Type B) RST active high hardware reset (default). E5 P0_1 DIO (Type B) I-PD INPUT/OUTPUT with selectable pull up/down resistors. Pull-down enabled during and after reset. General purpose I/O port bit or alternate function nodes. Contains state retention mechanism during power down. ADC0 AI INPUT. Analog to Digital Converter input 0. SWDIO DIO INPUT/OUTPUT. JTAG Data input/output. Bidirectional data and control communication. C5 P0_2 DIO (Type B) I-PD INPUT/OUTPUT with selectable pull up/down resistors. Pull-down enabled during and after reset. General purpose I/O port bit or alternate function nodes. Contains state retention mechanism during power down. ADC1 AI INPUT. Analog to Digital Converter input 1. SWCLK DIO INPUT JTAG clock signal (by default). B4 P0_3 DIO (Type B) I-PD INPUT/OUTPUT with selectable pull up/down resistors. Pull-down enabled during and after reset. General purpose I/O port bit or alternate function nodes. Contains state retention mechanism during power down. Check GP_DATA_REG[P03_P04_FILT_DIS] for correct pad filter settings. XTAL32kp AI INPUT. Analog input of the XTAL32K crystal oscillator. DI INPUT. Digital input for an external clock (square wave). A5 P0_4 DIO (Type B) I-PD INPUT/OUTPUT with selectable pull up/down resistors. Pull-down enabled during and after reset. General purpose I/O port bit or alternate function nodes. Contains state retention mechanism during power down. Check GP_DATA_REG[P03_P04_FILT_DIS] for correct pad filter settings. XTAL32km AO OUTPUT. Analog output of the XTAL32K crystal oscillator. D4 P0_5 DIO (Type B) I-PD INPUT/OUTPUT with selectable pull up/down resistors. Pull-down enabled during and after reset. General purpose I/O port bit or alternate function nodes. Contains state retention mechanism during power down. |
