Dual-processor �Cs lower
cost of MP3/WMA apps
Single-chip ASSPs combine ARM7 and Teak 16-bit DSP cores
The ML675200 series of single-chip microcontrollers claims to be the industry's first standard ARM-powered microcontrollers to combine dual-processor cores for audio/speech applications. The ASSP devices provide MP3/WMA and speech-processing designers with a standard solution that not only reduces development costs and development time, but does not require the usual up-front ASIC investments.
The devices feature a 32-bit ARM7 core for software processing with access to all general-purpose I/Os and a 16-bit Teak DSP core offering numerical processing for MP3/WMA decoding. Additional features for the 144-pin LFBGA microcontrollers include a USB 2.0 controller, 32 Kbytes of SRAM, 256 Kbytes of flash ROM (ML67Q5200 version), serial UART ports, and a four-channel DMA controller. (From $10 ea/100,000�samples available now.)
