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.
