DJ equipment is a device for playing back, mixing, and scratching music from CD and audio data as if they were from a vinyl record. DJ equipment is mainly made up of two DJ players and one DJ mixer. Although mainly used in North America and Europe until now, recently sales numbers of DJ equipment are increasing in emerging countries such as Russia and Brazil. In addition, although mostly used by businesses such as discos, due to the appearance of low-cost products private users are also increasing in number. Renesas Electronics simplifies the development of DJ equipment with SH726x 32-bit RISC microcontrollers with functions necessary for DJ equipment built-in and a lineup of motor drivers, power supply ICs, various standard ICs, optoelectronics devices, and so on. SH726x microcontrollers are built around the SH2A-FPU high-performance CPU core and integrate on-chip peripheral functions, such as an SD memory card interface, a NAND flash memory controller, USB, a CD-ROM decoder, and a serial sound interface. In addition, a variety of middleware products, such as an MP3 encoder/decoder, are available, allowing for flexible extension of functions and reducing the time required for system development.
