Description
The CS7410 is a true system-on-a-chip for the CD-
based digital audio market. With a powerful RISC pro-
cessor, one DSP, integrated audio ∆Σ modulator, large
internal SRAM and program ROM, and glueless inter-
face to popular CD chip sets, the CS7410 is a complete
single chip low-power programmable audio decoder.
This powerful architecture is easily capable of MP3,
WMA, and other future audio formats. The CS7410’s
flexible architecture and low power consumption make it
an ideal low-cost solution for a wide range of player ap-
plications. For portable audio systems, the memory
interface can be used to add DRAM or SRAM for Elec-
tronic Shock Protection (ESP). A flexible set of interfaces
are available for end-user I/O such as a keypad and LCD
control for use in mass market CD players, boom boxes,
and shelf-top systems.
