PRODUCTION DATA
| PIN | DESCRIPTION | ||
|---|---|---|---|
| NAME | TSSOP | UQFN, VQFN | |
| ADDR | 2 | 16 | Address input. Connect directly to VCCP or ground. |
| GND | 8 | 6 | Ground |
| INT | 13 | 11 | Interrupt output. Connect to VCCI through a pull-up resistor. |
| P0 | 4 | 2 | P-port input/output (push-pull design structure). At power on, P0 is configured as an input. |
| P1 | 5 | 3 | P-port input/output (push-pull design structure). At power on, P1 is configured as an input. |
| P2 | 6 | 4 | P-port input/output (push-pull design structure). At power on, P2 is configured as an input. |
| P3 | 7 | 5 | P-port input/output (push-pull design structure). At power on, P3 is configured as an input. |
| P4 | 9 | 7 | P-port input/output (push-pull design structure). At power on, P4 is configured as an input. |
| P5 | 10 | 8 | P-port input/output (push-pull design structure). At power on, P5 is configured as an input. |
| P6 | 11 | 9 | P-port input/output (push-pull design structure). At power on, P6 is configured as an input. |
| P7 | 12 | 10 | P-port input/output (push-pull design structure). At power on, P7 is configured as an input. |
| RESET | 3 | 1 | Active-low reset input. Connect to VCCI through a pull-up resistor, if no active connection is used. |
| SCL | 14 | 12 | Serial clock bus. Connect to VCCI through a pull-up resistor. |
