TI introduces breakthrough $1.95 DSP and $55 development kit, extending sophisticated signal processing and ultra-low power to new world of cost-sensitive applications

Texas Instruments TMS320C553x

New C553x ultra-low-power DSP generation offers industry's lowest price, lowest power DSPs
eZdsp development kit includes free software framework for USB audio and HID applications
Integrated high-speed USB 2.0 with PHY, power management and eMMC/SD controller
Ideal for audio and voice, medical, security, voice-activated home and many other applications
Code compatible with existing higher performance TMS320C5504/05/14/15 ultra-low-power DSPs

Texas Instruments Incorporated opened order entry for the new TMS320C553x ultra-low-power DSPs, enabling developers to add sophisticated signal processing to consumer audio and voice applications, portable medical equipment, biometric security, voice-activated home automation and flow meters — at an unprecedented price. The C553x DSPs offer the lowest price DSP in the industry starting at $1.95 and are supported by the $55 C5535 eZdsp development kit. The DSPs also offer up to two times lower active power consumption and up to six times lower standby power consumption than the nearest DSP competitor.

"It won't be long before cost-sensitive audio applications offer same-room voice clarity and surround-sound functionality, your fingerprint will give you access to your home and workplace, and your voice will activate your garage door," said Matt Muse, general manager, C5000 ultra-low-power DSP business unit, TI. "These incredible advancements can only be achieved with real-time signal processing. With TI's new C553x ultra-low-power DSPs, developers can add sophisticated digital signal processing to devices at the price point of a microcontroller and at the lowest active and standby power consumption rate in the industry. This enables superior consumer audio solutions with low BOM cost and long battery life."

TI software and tools: Enabling easy development and product differentiation

TI offers a free software framework for USB audio class and human interface device (HID) applications, enabling quick and easy implementation of real-time, reliable audio systems such as headsets, speakers and voice recorders. With this extensive software, developers can build solutions that will plug into a USB port, generate full duplex audio and allow control of audio volume via a USB HID interface.

Developers can begin working today with the C5535 eZdsp development kit for a one-time C55x promotional price of $55 for the next 55 days (normally priced at $99). The kit includes a credit-card-sized development board by Spectrum Digital, a free, full-featured version of Code Composer Studio (CCStudio) integrated development environment (IDE) ($495 value), headphones with microphone, a micro-SD card and an on-board emulator (up to $500 value). It also comes preloaded with the USB audio class and HID demo for an easy and comprehensive out-of-the-box experience.
