ST25TN01K-AFH5: can I connect a wire coil directly to the AC0/AC1 pads without a PCB?

Can I attach a hand-wound enamelled copper wire coil (about 0.05 to 0.1 mm wire) directly to the AC0 and AC1 pads of the UFDFPN5 package, with the chip mounted pads-up and the wire joined using solder or conductive epoxy, and no PCB? Is there any ST
