Toshiba Expands Media Player LSI Product Line With Two New Single-Chip CD-MP3 Processors For Car-Audio Market

Toshiba has announced two new highly integrated, high-performance CD- MP3 processors that enable playback of CD and multiple compressed audio formats from a single IC.

Features Chip-Level Integration of CD and MP3 Decoder DSPs Plus an SiP Version Incorporating DRAM Memory for ESP

They are aimed at car-audio as well as consumer-audio applications. Both devices integrate all necessary CD and audio processing features plus 1Mbit of SRAM and can decode up to four audio compression formats. TC94A73MFG is a system-in-package (SiP) version that adds electronic shock protection (ESP) to the feature set of TC94A70FG by incorporating built-in firmware and 16Mbit DRAM memory.

TC94A70FG and TC94A73MFG incorporate a CD servo and RF amplifier that control the CD spindle, pick-up head laser, and motor driver and amplify the RF signal generated from the reflection of the laser off the CD surface. A built-in CD DSP performs error correction and demodulation of the PCM/EFM signal while compressed audio content is decoded by a separate integrated audio DSP. The final audio signal can be output in digital I2S format or analog stereo from the built-in multi-bit DA converter.
