TMS570LS3137

The TMS570LS3137 is a high-performance 32-bit microcontroller from Texas Instruments, built on the ARM Cortex-R4F processor core operating at up to 200 MHz. It features an integrated memory subsystem with up to 1 MB of on-chip flash memory and 256 KB of SRAM, enabling fast execution and efficient data handling for real-time applications. The device supports dual-core lockstep operation for enhanced safety, making it ideal for systems requiring functional safety compliance such as ISO 26262 ASIL-D. This microcontroller includes a rich set of peripherals, including multiple high-speed communication interfaces such as CAN, LIN, SPI, I2C, and Ethernet MAC, which facilitate seamless integration into complex embedded systems. It also incorporates a hardware-based watchdog timer, a real-time clock (RTC), and a secure boot feature that ensures system integrity and protection against unauthorized access or tampering. The TMS570LS3137 integrates advanced safety mechanisms like ECC memory protection, self-test routines, and error detection circuits, ensuring robust operation in harsh environments. Its deterministic interrupt response and low-latency peripherals make it suitable for time-critical tasks in industrial automation, automotive control units, and medical devices. Additionally, the device supports external memory expansion through a dedicated memory controller, allowing scalability for larger applications. Designed for safety-critical applications, the TMS570LS3137 offers comprehensive diagnostic capabilities, including built-in self-test (BIST) for internal modules and runtime monitoring of key parameters. It also provides flexible power management options, including sleep modes and dynamic voltage scaling, to optimize energy consumption without compromising performance. Engineers benefit from a mature development ecosystem, including TI’s Code Composer Studio (CCS), real-time operating system (RTOS) support, and a wide range of application-specific libraries and drivers. The microcontroller is available in a 144-pin LQFP package, offering a balance of pin count, thermal performance, and ease of board layout for high-reliability designs.
