EXPOSED PAD MUST BE CONNECTED TO GROUND. 1 R7 2 R6 3 R5 4 R4 5 R3 6 R2 15 C6 16 C7 17 CMP_IN1/C8 18 CMP_IN2/C9 14 C5 13 C4 TOP VIEW (Not to Scale) ADP5588 PIN CONFIGURATION AND FUNCTION DESCRIPTIONS Figure 3. Pin Configuration Table 9. Pin Function Descriptions Pin No. Mnemonic Description 1 R7 GPIO, Row 7 in the Keypad Matrix. 2 R6 GPIO, Row 6 in the Keypad Matrix. 3 R5 GPIO, Row 5 in the Keypad Matrix. 4 R4 GPIO, Row 4 in the Keypad Matrix. 5 R3 GPIO, Row 3 in the Keypad Matrix. 6 R2 GPIO, Row 2 in the Keypad Matrix. 7 R1 GPIO, Row 1 in the Keypad Matrix. 8 R0 GPIO, Row 0 in the Keypad Matrix. 9 C0 GPIO, Column 0 in the Keypad Matrix. 10 C1 GPIO, Column 1 in the Keypad Matrix. 11 C2 GPIO, Column 2 in the Keypad Matrix. 12 C3 GPIO, Column 3 in the Keypad Matrix. 13 C4 GPIO, Column 4 in the Keypad Matrix. 14 C5 GPIO, Column 5 in the Keypad Matrix. 15 C6 GPIO, Column 6 in the Keypad Matrix. 16 C7 GPIO, Column 7 in the Keypad Matrix. 17 CMP_IN1/C8 GPIO, Column 8 in the Keypad Matrix; Comparator Input for Photosensor 1. 18 CMP_IN2/C9 GPIO, Column 9 in the Keypad Matrix; Comparator Input for Photosensor 2. 19 GND Ground. 20 RST Hardware Reset (Active Low). This bit resets the device to the power default conditions. The reset pin must be driven for a minimum of 50 μs to be valid and to prevent falsing due to ESD glitches or noise in the system. If not used, RST must be tied high with a pull-up. 21 VCC VCC = 1.7 V to 3.3 V. 22 SDA I2C Serial Data (Open Drain Requires External Pull-up). 23 SCL I2C Clock. 24 INT Processor Interrupt, Active Low, Open Drain. This pin can be pulled up to 2.7 V or 1.8 V for selection flexibility in the processor GPIO supply group. EP EPAD Exposed Pad. The exposed pad must be connected to ground. |
