System OverView
The Revolutionary MT6228 is a leading edge single-Chip solution for GSM/GPRS mobile phones targeting the emerging
applications in digital audio and video. Based on 32bit ARM7EJ-S
TM
RISC processor, MT6228 not only features high
performance GPRS Class 12 MODEM, but also provides comprehensive and advanced solutions for handheld multi-
media. But, the SDP100 can only support GPRS Class 8.
The Figure 1 is shown Typical Application for MT6228.
