UMTS/HSPA Module Series

UC20 Hardware Design

UC20_Hardware_Design Confidential / Released 12 / 82

UC20 is an SMD type module, which can be embedded in application through its 112-pin pads including

72 LCC signal pads and 40 other pads.

UC20 is integrated with internet service protocols like TCP/UDP and PPP. Extended AT commands have

been developed for customer to use these internet service protocols easily.
