RM46L852CPGET Product Details
The RM46L852CPGET deviceis a high-performance microcontroller family forsafety systems. The safety architecture includesdual CPUs in lockstep, CPUand memory BIST logic, ECC on both the flash and the data SRAM, parityonperipheral memories, and loopback capability on peripheral I/Os.
The RM46L852CPGET deviceintegrates the ARM Cortex-R4Ffloating-pointCPU which offers an efficient 1.66 DMIPS/MHz, andcan run up to 220 MHzprovidingup to 365 DMIPS.The device supports the little-endian [LE]format.
The RM46L852CPGET devicehas 1.25MB of integratedflash and 192KB ofdata RAM with single-bit error correction and double-bit error detection. Theflash memory on this device is a nonvolatile, electrically erasable andprogrammable memory, implemented with a 64-bit-wide data bus interface. Theflash operates on a3.3-V supply input (same level as I/O supply) for allread, program, and erase operations. When inpipeline mode, the flashoperates with a system clock frequency of up to 220 MHz. The SRAMsupportssingle-cycle read and write accesses in byte, halfword, word, and double-wordmodesthroughout the supported frequency range.
The RM46L852CPGET devicefeatures peripherals for real-time control-basedapplications, includingtwo Next Generation High-End Timer (N2HET) timingcoprocessorswith up to 44 I/O terminals, seven Enhanced Pulse WidthModulator (ePWM) modules with up to 14outputs, six Enhanced Capture (eCAP)modules, two Enhanced Quadrature Encoder Pulse (eQEP) modules,and two 12-bitAnalog-to-Digital Converters (ADCs) supporting up to 24 inputs.
The N2HET is an advanced intelligent timer that provides sophisticated timingfunctionsfor real-time applications. The timer is software-controlled, usinga reduced instruction set, witha specialized timer micromachine and anattached I/O port. The N2HET can be used forpulse-width-modulated outputs,capture or compare inputs, or general-purpose I/O (GIO). The N2HETisespecially well suited for applications requiring multiple sensor informationand driveactuators with complex and accurate time pulses. A High-End TimerTransfer Unit (HTU) can performDMA-type transactions to transfer N2HET datato or from main memory. A Memory Protection Unit (MPU)is built into theHTU.
TheePWM module can generate complex pulse width waveforms with minimalCPU overhead or intervention.The ePWM is easy to use and it supports bothhigh-side and low-side PWM and deadband generation.With integrated trip zoneprotection and synchronization with the on-chip MibADC, the ePWM moduleisideal for digital motor control applications.
TheeCAP module is essential in systems where the accurately timed captureof external events isimportant. The eCAP can also be used to monitor theePWM outputs or for simple PWM generation whenthe eCAP is not needed forcapture applications.
TheeQEP module is used for direct interface with a linear or rotaryincremental encoder to getposition, direction, and speed information from arotating machine as used in high-performancemotion and position-controlsystems.
The device hastwo12-bit-resolutionMibADCs with24 total inputsand 64 wordsof parity-protected buffer RAM each. The MibADC channels can beconverted individually or can begrouped by software for sequentialconversion sequences.Sixteeninputs are shared between the two MibADCs.Each MibADC supports three separate groupings ofchannels. Each group can beconverted once when triggered or configured for continuous conversionmode.The MibADC has a 10-bit mode for use when compatibility with older devices orfaster conversiontime is desired.MibADC1 also supports the use ofexternal analog multiplexers.
The device has multiple communication interfaces:three MibSPIs,twoSPIs, one LIN,oneSCI, three DCANs,one I2C,oneEthernet, and one USB module. The SPIprovides a convenient method of serialhigh-speed communications between similar shift-registertype devices. TheLIN supports the Local Interconnect standard 2.0 and can be used as a UART infull-duplex mode using the standard Non-Return-to-Zero (NRZ) format. The DCANsupports the CAN 2.0(A and B) protocol standard and uses a serial,multimaster communication protocol that efficientlysupports distributedreal-time control with robust communication rates of up to 1 Mbps. The DCAN isideal for systems operating in noisy and harsh environments (for example,automotive and industrialfields) that require reliable serial communicationor multiplexed wiring. The Ethernet module supports MII, RMII, andMDIOinterfaces.
The USB module includes a 2-port USB hostcontroller that is revision2.0-compatible, based on the OHCI specification for USB, release 1.0.The USBmodule also includes a USB device controller compatible with the USBspecification revision2.0 and USB specification revision 1.1.
TheI2C module is a multimaster communication module providing aninterface between the microcontrollerand an I2C-compatible devicethrough the I2Cserial bus. The I2C supports speeds of100 and 400 Kbps.
A Frequency-Modulated Phase-Locked Loop (FMPLL) clock module is used tomultiply theexternal frequency reference to a higher frequency for internaluse.The Global Clock Module (GCM) manages the mapping between the availableclock sources and thedevice clock domains.
The device also has an External Clock Prescaler (ECP) module that whenenabled, outputsa continuous external clock on the ECLK terminal. The ECLKfrequency is a user-programmable ratioof the peripheral interface clock(VCLK) frequency. This low-frequency output can be monitoredexternally as anindicator of the device operating frequency.
The Direct Memory Access (DMA) controller has 16 channels, 32 peripheralrequests,and parity protection on its memory. An MPU is built into the DMAto protect memory againsterroneous transfers.
The Error Signaling Module (ESM) monitors all device errors and determineswhether aninterrupt or external error pin (ball) is triggered when a faultis detected. The nERROR terminalcan be monitored externally as an indicatorof a fault condition in the microcontroller.
TheExternal Memory Interface (EMIF) provides a memory extension toasynchronous and synchronousmemories or other slave devices.
AParameter Overlay Module (POM) enhances the calibration capabilities ofapplication code. The POMcan reroute flash accesses to internal memory or tothe EMIF, thus avoiding the reprogramming stepsnecessary for parameterupdates in flash.
