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

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
1
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.
