1.3 Description
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.
The RM48Lx30 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. The
flash operates on a 3.3V supply input (same level as I/O supply) for all read, program and erase
operations. When in pipeline mode, the flash operates with a system clock frequency of up to 200MHz.
The SRAM supports single-cycle read/write accesses in byte, halfword, and word modes.
The RM48Lx30 device features peripherals for real-time control-based applications, including two Next
Generation High End Timer (N2HET) timing coprocessors with up to 44 total IO terminals and a 12-bit
Analog-to-Digital converter supporting up to 24 inputs.
