Audio decoding DSP, memory and CD functions integrated in single device

Toshiba Electronics Europe has extended its family of system-on-chip (SoC) audio digital signal processors (DSPs) with two new devices that combine decoding capability for MP3, WMA, ATRAC and AAC, along with CD control and amplification functions.

The company's TC94A70FG SoC device provides all necessary CD and audio processing functionality - including 1 Mbit of SRAM - in a single 100-pin QFP. The TC94A73MFG system-in-package (SiP) uses the same package to integrate the TC94A70FG along with DRAM memory for ESP (electronic shock protection). Both variants are pin-compatible and have low standby currents (10 μA maximum).

Toshiba says that the new devices will significantly simplify the implementation of home and vehicle audio systems by reducing component count and eliminating the overhead on system processors. Using the devices, designers can quickly implement a wide variety of functions including CD_DA play mode (with CD-text), compressed audio playback, ISO9660 disk analysis and control, audio playback and CD-ROM modes for data transfer. Digital filters, equalisation and dynamic range control, and sound field controls can also be provided without the need for additional components.

Dedicated CD functions include digital servo processor with integrated RF amplifier and a DAC. All of the devices offer 4-bit parallel interface and a 4-line serial interface for direct connection to a microcontroller. Serial, digital audio and analog interfaces - including one I²S input, three I²S outputs and an SPDIF connection - provide design flexibility for audio input and output.
