RM44L520APGET

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. The RM44Lx20 device features peripherals for real-time control-based applications, including two NextGeneration High-End Timer (N2HET) timing coprocessors with up to 44 total I/O terminals, seven Enhanced PWM (ePWM) modules with up to 14 outputs, six Enhanced Capture (eCAP) modules, two Enhanced Quadrature Encoder Pulse (eQEP) modules, and two 12-bit Analog-to-Digital Converters (ADCs) supporting up to 24 inputs. The N2HET is an advanced intelligent timer that provides sophisticated timing functions for real-time applications. The timer is software-controlled, using a reduced instruction set, with a specialized timer micromachine and an attached I/O port. The N2HET can be used for pulse-width-modulated outputs, capture or compare inputs, or general-purpose I/O (GIO). The N2HET is especially well suited for applications requiring multiple sensor information and drive actuators with complex and accurate time pulses. A High-End Timer Transfer Unit (HTU) can transfer N2HET data to or from main memory. A Memory Protection Unit (MPU) is built into the HTU. The ePWM module can generate complex pulse width waveforms with minimal CPU overhead or intervention. The ePWM is easy to use and supports complementary PWMs and deadband generation. With integrated trip zone protection and synchronization with the on-chip MibADC, the ePWM is ideal for digital motor control applications. The eCAP module is essential in systems where the accurately timed capture of external events is important. The eCAP can also be used to monitor the ePWM outputs or to generate simple PWM when not needed for capture applications.
