Description

General part information

RM44L520 Series

The RM44Lx20 device is part of theHerculesRM series of high-performance industrial-grade ARM® Cortex®-R-based MCUs. Comprehensive documentation, tools, and software are available to assist in the development of IEC 61508 functional safety applications. Start evaluating today with the HerculesRM LaunchPad Development Kit. The RM44Lx20 device has on-chip diagnostic features including: dual CPUs in lockstep; CPU and memory Built-In Self-Test (BIST) logic; ECC on both the flash and the SRAM; parity on peripheral memories; and loopback capability on most peripheral I/Os.

The RM44Lx20 device integrates the ARM Cortex-R4F floating-point CPU which offers an efficient 1.66 DMIPS/MHz, and has configurations which can run up to 180 MHz providing up to 298 DMIPS. The RM44Lx20 device supports the little-endian [LE] format.

The RM44Lx20 device has up to 1MB of integrated flash and 128KB of RAM configurations with single-bit error correction and double-bit error detection. The flash memory on this device is nonvolatile, electrically erasable and programmable, and is implemented with a 64-bit-wide data bus interface. The flash operates on a 3.3-V supply input (same level as the I/O supply) for all read, program, and erase operations. The SRAM supports single-cycle read and write accesses in byte, halfword, word, and doubleword modes throughout the supported frequency range.
