Dual core ARM Cortex-R5 accelerate performance

27 May 2014

Fast microcontroller targets developers’ functional safety industrial, medical, automotive and transportation designs.

The  32bit dual-core lockstep Hercules RM57Lx and TMS570LCx microcontrollers have been released for developers’ functional safety applications, by Texas Instruments.

The two floating-point devices offer a 50% increase in computational performance over any of the company’s current ARM Cortex-R MCUs, meaning that a single MCU can replace several discrete MCUs or be used in an FPGA-MCU combination.

They are claimed to provide the largest available on-chip flash and RAM in the Hercules platform. There is debug for code profiling and greater execution visibility, enabled by integrated real-time instruction and data trace support.

The lockstep and cached MCUs are software- and pin-compatible with the company’s existing Hercules MCU portfolio. The new versions allow developers to meet IEC 61508 functional safety standards for railway signaling, aviation anti-skid, programmable logic controllers, motors and drives and medical equipment.

Development Kits (TMDXRM57LHDK or TMDXTMS570LCHDK) include a development board, the Code Composer Studio IDE, timer co-processor IDE, HALCoGen peripheral configuration tool and safety demo.
