## 2. Key Features
### 2.1 Processing Power
- **Dual - Core Architecture**: The OMAPL138AZWTA3 features a dual - core design, combining an ARM926EJ - S core and a C674x DSP core. The ARM9 core provides a robust platform for running real - time operating systems (RTOS) and managing system tasks such as user interfaces, communication protocols, and system control. With a clock speed of up to 300 MHz, it can handle complex software applications efficiently.
- **High - Performance DSP**: The C674x DSP core, clocked at up to 456 MHz, offers exceptional floating - point and fixed - point processing capabilities. This makes it well - suited for applications that require intensive signal processing, such as audio and video processing, image recognition, and industrial control algorithms. The DSP's advanced instruction set and high - speed data paths enable it to perform complex calculations in real - time, enhancing the overall performance of the system.
### 2.2 Memory and Storage
- **On - Chip Memory**: The device comes with a significant amount of on - chip memory, including 128 KB of L2 memory and 32 KB of L1P and L1D memory. This on - chip memory provides fast access to frequently used data and instructions, reducing the need for external memory access and improving system performance.
- **External Memory Support**: The OMAPL138AZWTA3 supports a variety of external memory interfaces, such as SDRAM, DDR SDRAM, and NAND Flash. This allows developers to expand the system's memory capacity according to the specific requirements of their applications. The external memory interfaces are designed to operate at high speeds, ensuring seamless data transfer between the processor and the external memory.
### 2.3 Peripherals
- **Communication Interfaces**: It offers a comprehensive set of communication interfaces, including Ethernet, USB, UART, SPI, and I2C. The Ethernet interface supports both 10/100 Mbps speeds and can be used for network communication, enabling the device to connect to local area networks (LANs) and the Internet. The USB interface provides high - speed data transfer capabilities, making it suitable for connecting to external devices such as keyboards, mice, and storage devices.
- **Analog and Digital Interfaces**: The product series includes analog - to - digital converters (ADCs) and digital - to - analog converters (DACs), allowing it to interface with analog sensors and actuators. Additionally, it has general - purpose input/output (GPIO) pins, which can be used for various digital control and monitoring tasks.
### 2.4 Power Management
- **Low Power Consumption**: The OMAPL138AZWTA3 is designed with power - saving features in mind. It supports multiple power - saving modes, such as standby and sleep modes, which can significantly reduce power consumption when the device is not in use. This makes it an ideal choice for battery - powered applications and energy - efficient systems.
- **Dynamic Voltage and Frequency Scaling (DVFS)**: The processor also features DVFS technology, which
