series introduction
# TMS320C5535 Product Series Introduction
## 1. Overview
The TMS320C5535 belongs to Texas Instruments' TMS320C55x family of digital signal processors (DSPs). Renowned for its high - performance, low - power consumption, and rich peripheral integration, the TMS320C5535 is a versatile solution suitable for a wide range of applications in the fields of audio processing, industrial control, and portable devices.
## 2. Key Features
### 2.1 Processing Power
- **High - Speed CPU**: The TMS320C5535 is equipped with a high - performance CPU core that can operate at clock speeds up to 200 MHz. This enables it to execute complex digital signal processing algorithms with high efficiency, such as filtering, Fourier transforms, and speech recognition algorithms.
- **Dual - MAC Architecture**: It features a dual - multiply - accumulate (MAC) unit. This architecture allows the DSP to perform two MAC operations in a single cycle, significantly enhancing the computational throughput for applications that involve a large number of multiply - accumulate operations, like digital filtering and matrix multiplications.
### 2.2 Low - Power Design
- **Multiple Power Modes**: The device offers multiple power - saving modes, including active, idle, and standby modes. In idle mode, the CPU can be put to sleep while peripheral functions continue to operate, conserving power. In standby mode, the power consumption is further reduced, making it ideal for battery - powered applications.
- **Dynamic Voltage and Frequency Scaling (DVFS)**: The TMS320C5535 supports DVFS technology, which can adjust the supply voltage and operating frequency according to the workload. When the processing requirements are low, the voltage and frequency can be decreased, thereby reducing power consumption without sacrificing performance.
### 2.3 Memory Configuration
- **On - Chip Memory**: It has a generous amount of on - chip memory, including up to 128 KB of single - cycle access data RAM and up to 256 KB of program RAM. This on - chip memory allows for fast data access and execution of code, eliminating the need for external memory in many applications and reducing system cost and complexity.
- **External Memory Interface**: The DSP also provides an external memory interface (EMIF) that supports various types of external memories, such as synchronous dynamic random - access memory (SDRAM), flash memory, and static random - access memory (SRAM). This allows for easy expansion of the memory capacity when dealing with large - scale data processing tasks.
### 2.4 Peripheral Integration
- **Audio Interfaces**: The TMS320C5535 is well - suited for audio applications, thanks to its integrated audio interfaces. It includes a multi - channel buffered serial port (McBSP) that can be configured for various audio data formats, such as I2S (Inter - IC Sound), TDM (Time - Division Multiplexing), and PCM (Pulse - Code Modulation). This enables seamless connection to audio codecs, microphones, and speakers.
- **General - Purpose Input/Output (GPIO)**: There are a sufficient number of GPIO pins available, which can be used for a variety of purposes, such as controlling external devices, reading sensor data, or implementing simple communication protocols.
- **Timer Modules**: Multiple timer modules are integrated into the device, which can be used for tasks such as generating periodic interrupts, measuring time intervals, and implementing PWM (Pulse - Width Modulation) signals for motor control applications.
## 3. Development Tools and Ecosystem
- **Code Composer Studio (CCS)**: Texas Instruments provides the Code Composer Studio integrated development environment (
