TI’s Hercules MCUs target functional safety designs

Adding to its portfolio of SafeTI design components, Texas Instruments Incorporated (TI) has launched its latest 32-bit dual-core lockstep Hercules RM57Lx and TMS570LCx microcontrollers (MCUs) for developers’ functional safety applications. Unique to the Hercules MCU platform, these two new floating-point devices offer a 50 percent increase in computational performance over any of TI’s current ARM Cortex-R MCUs, allowing system designers to utilize a single Hercules MCU to replace several discrete MCUs or an FPGA-MCU combination.

These new Hercules MCUs also provide the largest available on-chip flash and RAM in the Hercules platform, along with several safety feature enhancements.  System and software developers will enjoy an insightful, efficient and powerful debug experience for code profiling and greater execution visibility, enabled by integrated real-time instruction and data trace support.

The Hercules RM57Lx MCUs help developers more easily and quickly meet IEC 61508 functional safety standards for a variety of applications, including railway signaling, aviation anti-skid, programmable logic controllers, motors and drives and medical equipment. The Hercules TMS570LCx MCUs will likewise help designers more easily and quickly meet the ISO 26262 functional safety standard for transportation applications like advanced driver assistance systems, domain control, electric propulsion systems, off-road vehicles.

The new Hercules RM57Lx and TMS570LCx MCUs:

  • Address greater application performance needs with lockstep ARM Cortex-R5 cores in a cached memory architecture with speeds up to 330MHz that delivers 550 peak DMIPS, 660 peak MIPS and up to 330 MFLOPS  These MCUs help further improve system performance with a new memory architecture supporting additional parallel bus master accesses and a multi-port direct memory access (DMA) controller.
  • Support ever-increasing application code size requirements and expand system functionality with the largest ECC enabled on-chip memory in the Hercules lineup with up to 4 MB of integrated program Flash, 512 KB of on-chip random access memory (RAM) and 128 KB of data Flash for EEPROM emulation.
  • Accelerate IEC 61508 SIL-3 and ISO 26262 ASIL-D compliance and end product application certificationwith Hercules MCUs and the accompanying SafeTI design package components, which includes: TI’s safety-related semiconductor components, quality manufacturing process, safety development process, safety-related documents, tools and software.

New Hercules RM57Lx MCUs are priced at $28.32 USD and FlexRay-enabled, Q100 qualified Hercules TMS570LCx MCUs are $32.15 USD in 10KU quantities and are immediately available for order in sample quantities.
