The LC823430TA audio processing system provides a single-chip solution by integrating digital signal processing (DSP) circuitry for MP3 encoding and decoding, and analog blocks such as audio analog-to-digital conversion (ADC) and digital-to-analog conversion (DAC).
The LC823430TA is a housed in space-saving 128-pin TQFP package with an overall height of just 1.2 mm maximum. The new device features segment-type LCD-connectable driver circuitry with two separate versions supporting either eight common by 18 segment (USB model) or four common by 36 segment (non-USB model) displays. Various flash memory interfaces such as SD/MMC and USB 2.0 device interface are also embedded within the design to provide further important space and BoM savings.
In addition to MP3 encoding and decoding, the LC823430TA's embedded DSP provides a noise cancellation feature to enhance the audio quality of recorded data by eliminating background noise such as wind or HVAC noise. A variable speed playback function is also included to allow audio data to be played back faster or slower without changing pitch. Further embedded analog circuitry provides a speaker and microphone amplifier and a programmable gain amplifier (PGA) with digital auto level control (ALC) for more consistent playback.
'With the introduction of the highly integrated LC823430TA, ON Semiconductor has strengthened its portfolio of products to support innovative, space saving design in the portable audio record and playback market,' said
ON Semiconductor is able to offer driver-level and middleware-level software optimized for its proprietary DSP and can help speed and ease the customer's design process further by providing additional application-level software and support.
