MT6252
GSM/GPRS Baseband Processor Data Sheet
Confidential A
MediaTek Confidential Release for1 System Overview
MT6252 is a GSM/GPRS handset chip solution which integrates RF, analog baseband, digital baseband as well as Power
Management Unit (PMU) and can greatly reduce the component count and make a smaller PCB size. Besides, MT6252 is
capable of Single Antenna Interference Cancellation (SAIC) and AMR speech. Based on a 32-bit ARM7EJ-STM RISC
processor, MT6252 provides an unprecedented platform with high quality modem performance. The typical application
diagram is shown as in Figure 1.
Cenon_WCXPlatform
MT6252 has the ARM7EJ-STM RISC processor running
MT6252 supports UART as well as a Bluetooth
interface. Also, it is embedded with necessary
at up to 104 MHz, which provides best trade-off
peripheral blocks: keypad scanner with the capability to
between system performance and power consumption.
detect the multiple key presses, multiple-SIM controller,
real time clock, PWM, LCD controller, USB 1.1 FS/LS,
For large amount of data transfer, high performance
MMC/SD and general purpose programmable I/Os.
Direct Memory Access (DMA) is implemented, which
greatly enhances the data movement speed while
MT6252 supports USB download with battery.
reducing MCU processing load.
Audio
Memory
Using a highly integrated mixed-signal Audio
MT6252 supports serial Flash interface with various
operating frequencies.
MediaTek Confidential Release forMultimedia
MT6252 multimedia system contains many hardware
accelerators to enrich user experience, including the
camera interface, display controller/resizer/rotator, etc.
MT6252 utilizes high resolution audio DAC, digital
audio, and audio synthesis technology to provide
superior audio features; e.g. MP3 ring tones.
Cenon_WCXConnectivity and Storage
Front-End architecture, MT6252 allows easy audio
interfacing with direct connection to the audio
transducers. The audio interface integrates D/A and
A/D converters for the voice band, as well as high
resolution stereo D/A converters for the audio band. In
addition, MT6252 provides stereo input and analog
mux, and supports the AMR codec to optimize speech
and audio quality.
The 700 mW class-AB amplifier is also embedded to
save the BOM cost without having to adopt an external
amplifier.
