Texas Instruments TMS570LS3137 RISC Flash Microcontrollers
Texas Instruments TMS570LS3137 16/32-Bit RISC Flash Microcontrollers provide safety architecture in a high-performance automotive-grade microcontroller designed for safety systems. The safety architecture incorporates ECC on both the flash and the data SRAM, CPU and memory BIST logic, parity on peripheral memories, loop-back capability on peripheral I/Os, and dual CPUs in lockstep. The TMS570LS3137 integrates the Arm® Cortex®-R4F Floating-Point CPU, which utilizes an efficient 1.66DMIPS/MHz. The CPU provides up to 298 DMIPS through configurations that can run up to 180MHz. 3MB of integrated flash and 256KB of data RAM offer single-bit error correction and double-bit error detection on the device. Other features include a variety of communication interfaces three MibSPIs, two SPIs, one LIN, one SCI, three DCANs, one I2C module, one Ethernet, and one FlexRay controller.
An External Clock Prescaler (ECP) module outputs a continuous external clock on the ECLK pin when enabled on the device. The Error Signaling module (ESM) monitors all device errors and determines whether an interrupt is generated or the external ERROR pin is toggled when a fault is detected. Offering off-chip expansion capability, the External Memory Interface (EMIF) delivers the ability to interface to synchronous DRAM (SDRAM) devices, asynchronous memories, peripherals, or FPGA devices. Various interfaces are utilized to enhance the debugging capabilities of application code, including the External Trace Macrocell (ETM), the RAM Trace Port (RTP) module, the Data Modification Module (DMM), and the Parameter Overlay Module (POM). The TMS570LS3137 Microcontrollers are an excellent solution with integrated safety features and a wide choice of communication and control peripherals for high-performance real-time control applications with safety-critical requirements.
