The LC823425 also has a Class D headphone amplifier to reduce power consumption during playback, it extends operating time, and enables noise cancellation, making audio clearer during playback.
SANYO has it scheduled to go into full production in July.
SANYO Semiconductor's 24-bit DSP also enables diverse audio processing algorithms, applying 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 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.
SANYO Semiconductor also offers to develop software to meet customers' specific needs and further expand the functionality of the product.
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. The device is priced at $7 per unit in quantities of 10,000 units.
