RM48L740-ZWT 16/32-Bit RISC Flash Microcontroller
The RM48Lx40 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 RM48Lx40 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.
The RM48Lx40 has up to 3MB integrated Flash and up to 256KB data RAM configurations with single bit error correction and double bit error detection. The flash memory on this device is a nonvolatile, electrically erasable and programmable memory implemented with a 64-bit-wide data bus interface
