MT6228 GSM/GPRS Baseband Processor Data Sheet Revision 1.0
1. System Overview
MT6228 is a feature-rich and extremely powerful
single-chip solution for high-end GSM/GPRS mobile
phones. Based on the 32-bit ARM7EJ-STM RISC
processor, MT6228’s superb processing power, along with
high bandwidth architecture and dedicated hardware
support, provides an unprecedented platform for high
performance GPRS Class 12 MODEM and leading-edge
multimedia applications. Overall, MT6228 presents a
revolutionary platform for multimedia-centric mobile
devices.
Typical application diagram is shown in Figure 1.
Platform
MT6228 is capable of running the ARM7EJ-STM RISC
processor at up to 104 MHz, thus providing fast data
processing capabilities. In addition to the high clock
frequency, separate CODE and DATA caches are also
added to further improve the overall system efficiency.
For large amounts of data transfer, high performance DMA
(Direct Memory Access) with hardware flow control is
implemented, which greatly enhances the data movement
speed while reducing MCU processing load.
Targeted as a media-rich platform for mobile applications,
MT6228 also provides hardware security digital rights
management for copyright protection. For further
safeguarding, and to protect the manufacturer’s
development investment, hardware flash content protection
is provided to prevent unauthorized porting of the software
load.
Memory
To provide the greatest capacity for expansion and
maximum bandwidth for data intensive applications such
as multimedia features, MT6228 supports up to 4 external
state-of-the-art devices through its 8/16-bit host interface.
High performance devices such as Mobile RAM and
Cellular RAM are supported for maximum bandwidth.
Traditional devices such as burst/page mode flash, page
mode SRAM, and Pseudo SRAM are also supported. For
greatest compatibility, the memory interface can also be
used to connect to legacy devices such as Color/Parallel
LCD, and multi-media companion chips are all supported
through this interface. To minimize power consumption
and ensure low noise, this interface is designed for flexible
I/O voltage and allows lowering of the supply voltage
down to 1.8V. The driving strength is configurable for
signal integrity adjustment. The data bus also employs
retention technology to prevent the bus from floating
during a turn over.
Multi-media
The MT6228 multi-media subsystem provides a
connection to a CMOS image sensor and supports a
resolution up to 3Mpixels. With its advanced image
signal and data processing technology, MT6228 allows
efficient processing of image and video data. Built-in
JPEG CODEC and MPEG-4 CODEC enable real-time
recording and playback of high-quality images and video.
A hardware MPEG4 accelerator supports playback in VGA
mode at 15fps and encoding in CIF at 15fps. Videophone
functionality is also provided. Moreover, a high quality
de-blocking filter is removes blocking artifacts in video
playback. GIF and PNG decoders are implemented for
fast image decoding. MT6228 supports a TV-OUT
capability, allowing the mobile handset to connect to a TV
screen via an NTSC or PAL connection.
In addition to advanced image and video features, MT6228
utilizes high resolution DAC, digital audio, and audio
synthesis technology to provide superior audio features for
all future multi-media needs.
Connectivity and Storage
To take advantage of its incredible multimedia strengths,
MT6228 incorporates myriads of advanced connectivity
and storage options for data storage and communication.
MT6228 supports UART, Fast IrDA, USB 1.1 Full Speed
OTG, SDIO, Bluetooth and WIFI Interface, and
MMC/SD/MS/MS Pro storage systems. These interfaces
provide MT6228 users with the highest degree of
flexibility in implementing solutions suitable for the
targeted application.
