MT2523D/G Datasheet
1. System Overview
MT2523G/D is a monolithic chip integrating leading edge power management unit, analog baseband and radio
circuitry based on the low-power CMOS process.
MT2523G/D is a feature-rich and extremely powerful single-chip solution for BT/BLE capability, and it is also ANT
hardware ready. Based on the Coretex-M4 processor, MT2523G/D’s superb processing power, along with high
bandwidth architecture and dedicated hardware support, provides a platform for high-performance wearable
application and leading-edge sensor control applications.
MT2523G/D is optimized for wearable products with the following strengths:
• Ultra small package size
• Ultra low power consumption for active and idle mode
• Dynamic voltage scaling for optimized computing power
• Built-in sensor hub and optimized sensor data capture engine
Platform
MT2523G/D is capable of running Coretex-M4 RISC processor, which provides the best trade-off between system
performance and power consumption.
MT2523G/D also provides a co-processor to offload the control for Bluetooth or GNSS. Coretex-M4 can easily use
API to enable Bluetooth or GNSS function and make Coretex-M4 focus on your applications.
For large amount of data transfers, 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.
A special sensor DMA is also equipped to support sensor data capture with ultra low power consumption.
Targeted as a media-rich platform for wearable applications, MT2523G/D also provides hardware security digital
rights management for copyright protection. To further safeguard and protect the manufacturer’s investment in
development, hardware flash content protection is provided to prevent unauthorized porting of the software load.
Special versions with GNSS embedded are also available for GNSS related wearable applications.
Memory
MT2523G/D is embedded with MTK-patented low power PSRAM to improve active and idle current.
MT2523G/D supports serial flash with various operating frequencies and flash sizes.
Multimedia
