466 / 483 page ![]() Hardware and layout Pin Name Type Description SAADC input 29 VSS Power Ground 30 DEC4 Power 1.3 V regulator supply decoupling Input from DC/DC regulator Output from 1.3 V LDO 31 DCC Power DC/DC regulator output 32 VDD Power Power supply Bottom of chip Die pad VSS Power Ground pad Exposed die pad must be connected to ground (VSS) for proper device operation. Table 99: QFN32 pin assignments 7.1.3 GPIO pins located near the radio Radio performance parameters, such as sensitivity, may be affected by high frequency digital I/O with large sink/source current close to the radio power supply and antenna pins. GPIO recommended usage on page 466 identifies some GPIO pins that have recommended usage guidelines for maximizing radio performance in an application. GPIO QFN48 pin QFN32 pin Recommended usage P0.25 37 26 P0.26 38 P0.27 39 P0.28 40 27 P0.29 41 Low drive, low frequency I/O only. Table 100: GPIO recommended usage 7.2 Mechanical specifications The mechanical specifications for the packages show the dimensions in millimeters. 7.2.1 QFN48 6 x 6 mm package Dimensions in millimeters for the nRF52810 QFN48 6 x 6 mm package. 4430_161 v1.0 466 |
