Description

The CS7410 is a true system-on-a-chip for the CD based digital audio market. With a powerful RISC processor, one DSP, integrated audio DS modulator, large internal SRAM and program ROM, and glueless interface 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 Electronic 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.
