Renesas Technology Europe has announced the development of a new ThreadX board support package from Express Logic for its SH7216 microcontroller. Customers using the integrated connectivity chip, the SH7216, which is aimed at real time control, will now have an additional option for their choice of operating system in the real time operating system, ThreadX, which also delivers connectivity software.
The SH7216 is one of Renesas’ newest microprocessors. The target markets for the SH7216 can be broadly split into two sections. The first is “connectivity”, with this SuperH device featuring communication interfaces such as Ethernet, CAN and USB. The SH716 is available in 72 different variations meaning that there will be a suitable device, package, performance product whatever the connectivity application.
The second market area for the SH7216 is inverters, including solar inverters, motor control and others. The SH7216 features two dedicated timer units, each capable of automatic deadtime insertion, deadtime optimisation and automatic synchronisation with the analogue to digital converter.
The SH2-A core is capable of 480 DMIPS and 400 MFLOPS performance and enables extremely fast interrupt response (as low as 30 ns), while the SH7216 also contains up to 1 MB of the industry’s fastest embedded flash: MONOS flash, which is only available from Renesas.
Express Logic’s ThreadX real-time operating system (RTOS) is a robust library of application-callable operating system services that simplify and optimise the performance of an embedded system. ThreadX is designed for microcontroller-based applications, and features a small memory footprint of under 6 KB so it can reside in even the most limited on-chip MCU memory. It provides preemptive, real-time, priority-based scheduling for optimum responsiveness and high performance. Services include thread scheduling, message passing, resource allocation, synchronization, and interrupt management.
With ThreadX, user applications are easily managed and remain easily portable to higher-or lower-performance SH2-A core-based processors. ThreadX is complemented by FileX, a full embedded file system, NetX, a rich but small-footprint IPv4/IPv6 TCP/IP stack, USBX, a full USB Host/Device/OTG stack, and PEGX, a graphics development toolkit. TraceX, Express Logic’s graphical real-time event analysis development tool also is available for use with applications running on the SH7216. ThreadX is provided in full source code form, and is fully integrated into the Renesas HEW IDE, for a quick start to application development.
