C94A70FG

TC94A70FG/TC94A73MFG Single-chip CD-MP3 Processor

Highlights

• Highly integrated solution

with CD servo, RF amp,

1 Mbit SRAM, multi-bit DA

converter and audio DSP

with firmware library

including MP3, WMA,

ATRAC CD, AAC, graphic

equalization, and popular

surround sound formats

• Pin compatibility between

monolithic TC94A70FG

and system-in-package

(SiP) TC94A73MFG with

16 Mbit DRAM enables a

single hardware design to

support standard and

electronic shock protection

(ESP) CD playback

versions

• Macro commands simplify

software programming

• Programmable RAM and

pin-compatible ROM

solutions enable

customization and

reduced time to market.

Description

TC94A70FG and TC94A73MFG are highly

integrated, high-performance CD-MP3

solutions that enable playback of CD and

multiple compressed audio formats from a

single chip. Featuring high-quality audio

output in I

2

S, S/PDIF or analog stereo

formats, the TC94A70FG integrates an RF

amplifier, CD servo, audio DSP, 1 Mbit

SRAM, and a multi-bit DA converter in a

CMOS monolithic IC. To the TC94A70FG

feature set, the TC94A73MFG adds

electronic shock protection (ESP) with

DSP firmware and 16 Mbit DRAM in an

SiP solution. TC94A70FG and

TC94A73MFG are available in standard

ROM versions or can also be customized

to specific customer requirements using

an extensive and growing DSP firmware

library including MP3, WMA, ATRAC CD,

AAC, graphic equalization and popular

surround sound formats. Pin compatibility

between the monolithic TC94A70FG and

the SiP TC94A73MFG minimizes the

Product Brief

TC94A70FG/TC94A73MFG

Single-chip CD-MP3 Processor

engineering investment needed to upgrade

TC94A70FG CD playback designs with ESP.

New product design is further aided by

programmable RAM and macro commands

that simplify CD mechanism playback and

compressed audio tag and file management.

High integration, software customization, and

pin-compatible packages make TC94A70FG

and TC94A73MFG ideal for compressed

audio CD players where low cost, feature

flexibility and time to market are key

selection criteria.
