Main Features：

1. Core & Performance

Heterogeneous Dual-Core Architecture: Integrates a 200 MHz Arm® Cortex®-M33 application processor core and a dedicated 200 MHz DSP signal processor core, enabling parallel and efficient execution of control and signal processing tasks.

Powerful Processing Capability: The M33 core integrates a Single-Precision Floating-Point Unit (FPU); the DSP core supports SIMD instructions and floating-point operations, making it an ideal choice for complex computations such as Fast Fourier Transform (FFT), filtering, and voice codec.

2. Advanced Peripherals & Interfaces

Advanced Audio Interfaces: Integrates a High-Performance Audio Interface (HIFI-Audio), including I2S, S/PDIF input/output, supporting high-fidelity audio transmission.

Graphics Display Support: Built-in TFT LCD controller and hardware graphics accelerator (IPA), capable of directly driving displays, suitable for audio equipment with interactive interfaces.

Rich Connectivity: Provides 10/100M Ethernet MAC, USB 2.0 OTG FS, CAN 2.0B, as well as multiple USART, I2C, and SPI interfaces.

High-Speed Analog Front-End: Equipped with high-precision, high-speed ADC and DAC, optimized for high-quality audio sampling and reconstruction.

Camera Interface: Supports DCMI (Digital Camera Interface), enabling vision function expansion.

3. Memory, Package & Reliability

Large-Capacity Memory: Inferred configuration includes 1024KB (1MB) Flash and 512KB SRAM, providing ample space for dual-core code, audio data buffers, and complex algorithms.

Advanced Package: The "AZ" in the model number may indicate a 144-pin LQFP or TFBGA package, offering rich I/O in a compact size.

Enhanced Temperature Range: The suffix "T3TB" is very specific. "T3" most likely represents an extended industrial temperature range, such as -40°C to +105°C or higher. "TB" typically indicates Tape and Reel packaging. This combination suggests that this model is designed for mass production in demanding industrial and automotive applications.

Typical Applications：

Its dual-core architecture and professional audio peripherals make it an ideal platform for the following high-end applications:

Professional Audio Equipment: Digital audio mixers, effects processors, digital processing core for audio power amplifiers, broadcasting equipment.
