The I2C module is a multimaster communication module providing an interface between the
microcontroller and an I2C-compatible device via the I2C serial bus. The I2C supports speeds of 100 and
400 Kbps.
The frequency-modulated phase-locked loop (FMPLL) clock module is used to multiply the external
frequency reference to a higher frequency for internal use. There are two FMPLL modules on this device.
These modules, when enabled, provide two of the seven possible clock source inputs to the global clock
module (GCM). The GCM manages the mapping between the available clock sources and the device
clock domains.
The device also has an external clock prescaler (ECP) module that when enabled, outputs a continuous
external clock on the ECLK pin/ball. The ECLK frequency is a user-programmable ratio of the peripheral
interface clock (VCLK) frequency. This low-frequency output can be monitored externally as an indicator of
the device operating frequency.
The DMA controller has 16 channels, 32 control packets and parity protection on its memory. An MPU is
built into the DMA to limit the DMA to prescribed areas of memory and to protect the rest of the memory
system from any malfunction of the DMA.
The Error Signaling Module (ESM) monitors all device errors and determines whether an interrupt is
generated or the external ERROR pin is toggled when a fault is detected. The ERROR pin can be
monitored externally as an indicator of a fault condition in the microcontroller.
The External Memory Interface (EMIF) provides off-chip expansion capability with the ability to interface to
synchronous DRAM (SDRAM) devices, asynchronous memories, peripherals or FPGA devices.
Several interfaces are implemented to enhance the debugging capabilities of application code. In addition
to the built in ARM Cortex-R4F CoreSight debug features an External Trace Macrocell (ETM) provides
instruction and data trace of program execution. For instrumentation purposes, a RAM Trace Port (RTP)
module is implemented to support high-speed tracing of RAM and peripheral accesses by the CPU or any
other master. A Data Modification Module (DMM) gives the ability to write external data into the device
memory. Both the RTP and DMM have no or only minimum impact on the program execution time of the
application code. A Parameter Overlay Module (POM) can reroute flash accesses to internal memory or to
the EMIF. This rerouting allows parameters and tables to be dynamically calibrated against production
code without rebuilding the code to explicitly access RAM or halting the processor to reprogram the data
flash.
With integrated safety features and a wide choice of communication and control peripherals, the
RM48Lx50 device is an ideal solution for high-performance real-time control applications with safety-
critical requirements.
