Pin Configuration PIN DESCRIPTION Pin Mnemonic I/O Supply Function 1 OPT3 I VBAT Optional Power ON input. ADP3500 will keep “power ON” during this pin goes “High”. 2 KEYPADCOL0 O LDO1 Keypad Column Strobe 0 (Open Drain, pull low) 3 KEYPADCOL1 O LDO1 Keypad Column Strobe 1 (Open Drain, pull low) 4 KEYPADCOL2 O LDO1 Keypad Column Strobe 2 (Open Drain, pull low) 5 KEYPADCOL3 O LDO1 Keypad Column Strobe 3 (Open Drain, pull low) 6 KEYPADROW0 I LDO1 Keypad Row Input 0. Pulled up internally, 10K Ω 7 KEYPADROW1 I LDO1 Keypad Row Input 1. Pulled up internally, 10K Ω 8 KEYPADROW2 I LDO1 Keypad Row Input 2. Pulled up internally, 10K Ω 9 KEYPADROW3 I LDO1 Keypad Row Input 3. Pulled up internally, 10K Ω 10 KEYPADROW4 I LDO1 Keypad Row Input 4. Pulled up internally, 10K Ω 11 KEYPADROW5 I LDO1 Keypad Row Input 5. Pulled up internally, 10K Ω 12 TCXO_ON I LDO1 Logic input pin for Main LDOs (LDO1, LDO2, LDO3, LDO6) turning on control. L: OFF, H: ON 13 SLEEP- I LDO1 Logic input pin for RF Rx LDOs (LDO7 and LDO9). Gating register data with this input for these LDOs. LDO7 and LDO9 are turned OFF when SLEEP- goes Low even if the registers set to ON. 14 BLIGHT O VBAT LED drive. Open drain output. 15 DGND - - Digital Ground 16 INT- O LDO1 Interrupt signal output 17 RTCV - - Supply input for RTC, 32KHz OSC, and some other logics. Connects to Coin cell battery in typical operation. 18 OSCOUT - RTCV Connect to 32.768KHz crystal. 19 AGND - - Analog Ground 20 OSCIN - RTCV Connect to 32.768KHz crystal. 21 GPIO0 I/O LDO1 General Purpose Input and Output port. Integrated Interrupt function. Interrupt occurs both falling and raising edge. 22 GPIO1 I/O LDO1 General Purpose Input and Output port. Integrated Interrupt function.
