TI RM48Lx30安全系统MCU解决方案

TI公司的RM48Lx30是高性能安全系统用的微控制器(MCU),它的安全架构包括两个步调一致的CPU,CPU和存储器内置自测(BIST)逻辑,闪存和数据SRAM的ECC,效率高达1.6 DMIPS/MHz的ARM® Cortex™-R4F浮点CPU,并可配置到在200MHz运行,提供高达320DMIPS,支持little-endian [LE32]格式,主要用在工业安全系统如工业自动化,安全PLC,电源产生和分布,电梯以及医疗电子如呼吸机, 心脏除颤器, 输液泵和胰岛素泵, 放射疗法和手术机器人等.本文介绍了RM48Lx30主要特性, 功能方框图和RM48 Hercules™ ARM® Safety MCU开发套件(HDK)主要特性,方框图与电路图.

The RM48Lx30 is a high performance microcontroller family for safety systems. The safety architecture includes Dual CPUs in lockstep, CPU and Memory Built-In Self Test (BIST) logic, ECC on both the Flash and the data SRAM, parity on peripheral memories, and loop back capability on peripheral IOs.

The RM48Lx30 integrates the ARM® Cortex™-R4F Floating Point CPU which offers an efficient 1.6 DMIPS/MHz, and has configurations which can run up to 200MHz providing up to 320 DMIPS. The device supports the little-endian [LE32] format.
