mt2503d is a monolithic chip integrating leading edge power management unit, analog baseband and radio circuitry based on the low-power CMOS process.
MT2503D is a feature-rich and extremely powerful single-chip solution for high-end GSM/GPRS capability. Based on the 32-bit ARM7EJ-S TM RISC processor, MT2503D’s superb processing power, along with high bandwidth architecture and dedicated hardware support, provides a platform for high-performance GPRS Class 12 MODEM application and leading-edge multimedia applications.
MT2503D also features:
A highly integrated Bluetooth transceiver which is fully compliant with Bluetooth specification v4.0.
A FM receiver supporting both audio broadcast de-modulation and RDS/RBDS data decoding.
Typical application diagram is shown in Figure 1.
Platform
MT2503D is capable of running the ARM7EJ-S TM RISC processor, which provides the best trade-off between system performance and power consumption.
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 the MCU processing load.
Targeted as a media-rich platform for mobile applications, MT2503D also provides hardware
