Dualcore Semiconductor has launched its DCIC9907 microcontroller (MCU) that contains two ARM 946E cores, two CAN channels, two 10Mbit/100Mbit Ethernet MACs with hardware extension for real-time protocols.

This new SoC also offers motion control logic capability, specifically designed for time-critical and other industrial control applications. It allows users to control applications under difficult real-time conditions, such as tasks which need accurately predicted time performance under all conditions, even when running in parallel with an operating system.

Within the DCIC9907, one of the two ARM cores can be used for complex real-time control and the second one for system infrastructure, such as human machine interface and the required communication interfaces. For this purpose, the versatile real-time operating system EUROS has been ported to DCIC9907.

The two 10Mbit/100Mbit Ethernet MAC ports have hardware extensions which support real time protocols via Ethernet. Features incorporated in DCIC9907 are the direct result of feedback from key industrial users, said the company. For instance, the DCIC9907 includes 16 hardware interrupts controlled via the internal vector interrupt controller with a total of 32 interrupts available (16 software + 16 hardware).

An additional feature is a complex-motion control block integrated into the DCIC9907. This control block has all the built-in features necessary to control and supervise any kind of electronic motor directly from the IC. For example, it is possible to control 3 PWM channels in parallel. Dualcore added that the DCIC9907 can be clocked up to 128MHz and provides sufficient performance even for very demanding control applications. With 109 I/O pins, this product represents a highly flexible SoC.

The DCIC9907 will be available starting next (March 2006) in an industrial temperature range 305-pin BGA package at under $20 in volume.
