Texas Instruments TMS570LC4357/TMS570LC4357-EP Arm® Cortex®-R5 MCU

Texas Instruments TMS570LC4357/TMS570LC4357-EP 32-Bit Arm® Cortex®-R5 Based Microcontroller (MCU) is a high-performance automotive-grade Arm Cortex-R-based MCU. The TMS570LC4357/TMS570LC4357-EP has on-chip diagnostic features that include dual CPUs in lockstep and Built-In Self-Test (BIST) logic for CPUs. This device also includes N2HET coprocessors, and for on-chip SRAMs, ECC protection on the L1 caches, L2 flash, and SRAM memories. The device also supports ECC or parity protection on peripheral memories and loopback capability on peripheral I/Os. The TMS570LC4357/TMS570LC4357-EP integrates two Arm Cortex-R5F floating-point CPUs, operating in lockstep. This integration offers an efficient 1.66 DMIPS/MHz and can run up to 300MHz, providing up to 498DMIPS. The device supports the big-endian [BE32] format. The Texas Instruments TMS570LC4357-EP devices have gold bond wires, a temperature range of –55 to +105°C, and include an SnPb lead finish.
