Texas Instruments Incorporated (TI) opened
order entry for the new TMS320C553x ultra-low-power
DSPs on Friday, Aug. 26, 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.
Customers
can easily migrate between the C553x DSPs and also to the software-compatible
C5515, C5514, C5505 and C5504 ultra-low-power DSPs to rapidly create multiple
unique end products that maximize R&D investment and existing software base.
In addition, devices within the C553x DSP generation are also pin-to-pin
compatible, enabling easy scalability to add varying functionality to a customer’s
product portfolio.
