9 / 291 page  Pre-Production WM8310 w PP, May 2012, Rev 3.1 9 3 PIN DESCRIPTION Notes: 1. Pins are sorted by functional groups. 2. The power domain associated with each pin is noted; VPMIC is the domain powered by LDO12 for the ‘always-on’ functions internal to the WM8310. 3. Note that an external level-shifter may be required when interfacing between different power domains.
