The TMDX5535eZdsp is a small form factor, very low cost USB-powered DSP development kit which includes all the hardware and software needed to evaluate the C553x and C5545 DSP families, which are the industry’s lowest-cost and lowest power 16-bit DSP. This ultra-low-cost kit allows quick and easy evaluation of the advanced capabilities of the C5532, C5533, C5534, C5535 and C5545 processors. The kit has an on-board XDS100 emulator for full course-level debug capability and supports Code Composer Studio™ (CCStudio) Integrated Development Environment (IDE) and eXpressDSP™ software which includes the DSP/BIOS™ kernel. The full contents of the Development Kit include C5535 ezdsp board, CCStudio IDE, and headphone with mic, a 2-GB micro SD card, a free software framework for USB audio class and human interface device (HID) applications and an out-of-the-box comprehensive demo for USB audio class applications.


The C5532, C5533, C5534, C5535 and C5545 are the industry’s lowest cost and lowest power 16-bit processors helping conserve energy at exceptional levels and enabling longer battery life. With 200 MIPS performance, up to 320KB on-chip memory, higher integration (including a hardware accelerator for FFT computation) than comparable devices, the C553x/C5545 product generations provides a foundation for a range of signal processing applications, including voice triggering, audio recorder, musical instruments, portable medical solutions and other electronics in industrial and security applications.
