Description
General part information
RM57L843 Series
The RM57L843 device is part of theHerculesRM series of high-performance 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 theHercules RM57x LaunchPad Development Kit. The RM57L843 device has on-chip diagnostic features including: dual CPUs in lockstep, Built-In Self-Test (BIST) logic for CPU, the 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 RM57L843 device integrates two ARM Cortex-R5F floating-point CPUs, operating in lockstep, which offer an efficient 1.66 DMIPS/MHz, and can run up to 330 MHz providing up to 547 DMIPS. The device supports the little-endian [LE] format.
The RM57L843 device has 4MB of integrated flash and 512KB of data RAM 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 3.3-V supply input (the same level as the I/O supply) for all read, program, and erase operations. The SRAM supports read and write accesses in byte, halfword, and word modes.
