Atmel® Corporation has announced its 200 MIPS ARM926EJ-STM–based microcontroller that overcomes the bottlenecks engendered by graphically-interfaced, data-intensive applications such as networked medical monitoring equipment and GPS navigation systems. It uses 27 DMA channels including the company’s 18-channel peripheral DMA controller (PDC), a nine layer bus matrix, and two additional busses for data- and instruction-tightly-coupled-memories (TCMs) that boost CPU performance and on-chip data transfer rates of up to 41.6 Gbps. Two external bus interfaces (EBIs) allow support for GByte-plus external memories. On-chip human interface peripherals include a camera interface, TFT/STN LCD controller, a 6-channel audio front end interface (AC97), I2S and a 2-D graphics co-processor that off-loads line draw, block transfer, polygon fill, and clipping functions from the CPU.
