Sanyo Introduces New ARM-based Audio Processing Solution For Portable Applications

Sanyo Semiconductor today announced the introduction of LC823425, an audio processing solution for portable devices such as IC recorders.

The product features a built-in hardwired MP3 encoder/decoder system, enabling a power consumption of just 5 milliwatts (mW) and supporting advanced functionality via a built-in digital signal processor (DSP).

The LC823425 lowers power consumption during encoding by 50 percent compared to prior products, by utilizing a newly developed hardware encoders for MP3 file formats. It also employs a, low-voltage 90 nanometer (nm) process to achieve overall power consumption of approximately 5 mW. Additionally, it features a Class D headphone amplifier to reduce power consumption during playback. Through these functions, LC823425 achieves power consumption 30 percent lower than that of earlier sound processing products such as the LC823410.

SANYO Semiconductor's 24-bit DSP also enables diverse audio processing algorithms, leveraging proven software assets, shortening time to market for various types of audio processing applications. For example, this device enables functions often used for IC recorders, such as noise cancellation (including reducing noise from air conditioners, and making audio clearer during playback), sound collection (making audio clearer in real-time by using low delay noise-reduction processing and a high-gain amplifier), and voice speed adjustment (lowering voice speed, and maintaining the original playback time by expanding voice data to silent parts).

The new MP3 decoder and playback algorithm included in the LC823425 enables the variable speed playback function to operate at up to twice the speed [at 0.5x to 4x speeds and 1.2 volts (V) operation], compared to SANYO Semiconductor's previous products.

Additionally, by utilizing the LC823425's "music extraction technology", which extracts music data from among audio data, it also possible to extract and record only the music part of an FM radio broadcast.

Samples of LC823425 are already available. Full production is scheduled in July 2011. The device is offered in both a FBGA221J (11 mm x 11 mm) and a TQFP128L (14 mm x 14 mm) package. It is budgetary priced at $7.00 USD per unit in quantities of 10,000 units.
