Hao Qi Core Technology is the agent of Texas Instruments lowest power 16-bit digital signal processor TMS320C5514 and TMS320C5515. In order to help customers start the design work quickly, Haoqixin Technology will analyze these two evaluation board solutions, including the full-featured TMDXEVM5515 and the low-cost TMDX5515EZDSP evaluation board.

The two low-power TMS320C55x DSPs not only increase performance by 20% to 120 MHz, but also increase integration and simplify system-level development, enabling customers to add more encoding and decoding in voice, audio and portable communications applications Algorithms and other features add real-time diagnostic capabilities to medical terminal equipment while ensuring extremely low power consumption. In addition, these devices integrate power management features such as on-chip LDOs (low dropout regulators) and dynamic voltage and frequency scaling, so customers can maximize and efficiently manage battery life in portable devices.

The main features and advantages of TMS320C5514 DSP:

1. 3 on-chip LDOs are used for DSP core, USB and analog subsystem respectively;

2. SDRAM and mobile SDRAM can support low-power applications;

3. Highly integrated peripherals including high-speed USB 2.0, I2S, UART, SPI, MMC/SD and GPIO can reduce system cost and support more user-friendly and portable features;

4. The on-chip memory capacity is up to 256 KB, which can reduce the demand for external memory, thereby reducing power consumption and system cost;

5. Dynamic voltage and frequency scaling helps maximize battery life in portable applications.

(In addition to C5514 performance) the main features and advantages of TMS320C5515 DSP:

1. TMS320C5515 adds 64KB on-chip memory capacity (total 320KB) on the basis of TMS320C5514;

2. Programmable FFT hardware accelerator up to 1024 points;

3. Integrated LCD display controller and 10-bit 4-channel SAR ADC can reduce system cost and achieve more user-interactive portable features;

4. Expanded on the basis of TMS320C5514 and compatible with its pin-to-pin, so that customers can not only choose the best device for their application with high flexibility, but also get convenient upgrade options to build highly robust products series.

 

Price, availability and tools of TI‘s 16-bit DSP TMS320C5514 and TMS320C5515:

The full-featured TMDXEVM5515 evaluation board is compatible with the C5514 and C5515 low-power DSPs and comes with a complete software library and several application demonstrations.
