  1. Standardization on Integrated I/O Connection Interface for mobile devices Hyeon-Woo Lee Chair, IMT-Adv. Proj. Group, TTA (woojaa@iita.re.kr) Zhangjiajia, China 8-10 April 2009

  2. Contents Background History Characteristic Conclusion

  3. 1. Background • Purpose and Background • To maximize consumer benefits on using single peripheral like a charger by integrating I/O connection interfaces that are different among each manufacturer • To minimize the wasting of both costs and resources by leading customers to reuse the peripherals. • To promote developing new products and improve the technical competitiveness of mobile phones and devices.

  4. 2. History • History • June 2000 : Initiation on integrated I/O connection interface work • March 2001 : 1st edition, 24pins (TTAS.KO-06.0028) • December 2001 : 2nd edition(revised version), 24pins (TTAS.KO-06.0028/R1) • December 2002 : 3rd edition(revised version), 24pins (TTAS.KO-06.0028/R2) • April 2007 2007 : 4th edition, 20pins (TTAS.KO-06.0028/R3) • November 2007 : 5th edition(revised version), 20pins (TTAS.KO-06.0028/R4)

  5. New & Integrated Incumbent + Earphone Battery Charger 20 pin 24 pin (Since 2001) TV Out Cable USB Data Cable 3. Characteristic - Features • New Standard on Integrated I/O Connection Interface for Mobile Phones (Revised inNov. 2007, certified in Jun. 2008) • To meet the slimming & miniaturizing trend as well as to increase consumer benefits • Estimated cost saving : USD 10mil. per year Adapter for 24pin-20pin is available 5

  6. 3. Characteristic – Electrical • Function by pins pin Signal I/O note pin Signal I/O note 1 Power Ground power Charge, common GND 11 On switch I/O Remote power on 2 Reserved - reserved 12 reserved - reserved 3 EAR_MIC + input Differential MIC + Signal 13 Battery ID input Battery detection 4 EAR_MIC – input Differential MIC - Signal 14 TV out output Composite analogvideo outout 5 EAR_L output Headset left 15 UART_RXD input UART signal input 6 EAR_R output Headset right 16 URAT_TXD output UART signal output 7 Device-sense Device-detection input Device ID 17 VBUS power USB +5.0V power input 8 Remote Key input Divece Key 18 USB D- I/O Minus line of the differential, bi-directional USB signal 9 Power (+4.2V)/SWB+ power Charge, power 19 USB D+ I/O Plus line of the differential, bi-directional USB signal 10 Power (+4.2V)/SWB+ power Charge, power 20 Power ground power Power GND, common GND

  7. 3. Characteristic - Mechanical (Socket part) (Plug part) pin width width 24 pins 16.3 mm 3 mm Integrated 20 pins 10.6 mm 2.6 mm

  8. 4. Conclusion • Why ? • Single I/O connection interface of various kinds of mobile/portable devices • To maximize user convenience • To reduce cost of mobile devices • To minimized the wasting of resources • What ? - Further collaboration on integrated I/O connection interface • Potential collaboration among CJK • Potential collaboration with GSMA UCS initiatives • Forward compatibility with UCS can be considered.

  9. Annex: GSMA Universal Charging Solution (UCS) plan • During MWC ’09, UCS initiatives was launched. • Major vendors and operators • Nokia, Samsung, LG, Motorola, SONY-Ericsson, Qualcomm • Vodafone, T-mobile, Orange, 3, Telefonica, AT&T, Telenor, KTF, Telstra, Mobilkom Austria, Telecom Italia • Electrical & Mechanical Interface: Micro USB • Details will be discussed: charging only, charging and data, etc. • Target completion date: 2012 • Effects • Elimination of 5100 tons of duplicated chargers • 50% reduction of standby energy • Reduction of 13.6 M tones of greenhouse gas per year • Assumption: 1.2 B mobile phone @2008, 50-80% are replacements
