The real-time control subsystem is based on TI’s 32-bit C28x DSP core, which provides 200 MIPS of signalprocessing
performance in each core for floating- or fixed-point code running from either on-chip flash or SRAM.
This is equivalent to the 400-MHz processing power on a Cortex?-M7 based device (C28x DSP core gives two
times more performance than the Cortex?-M7 core).The C28x CPU is further boosted by the Trigonometric Math
Unit (TMU) and VCRC (Cyclical Redundancy Check) extended instruction sets, speeding up common algorithms
key to real-time control systems. Extended instruction sets enable IEEE double-precision 64-bit floating-point
math. Finally, the Control Law Accelerator (CLA) enables an additional 200 MIPS per core of independent
processing ability. This is equivalent to the 280-MHz processing power on a Cortex?-M7 based device (CLA
CPU gives 40 more performance than the Cortex?-M7 core).
The lockstep dual-CPU comparator option has been added in the secondary C28x CPU along with ePIE and
DMA for detection of permanent and transient faults. To allow fast context switching from existing to new
firmware, hardware enhancements for Live Firmware Update (LFU) have been added to F28P65x.
High-performance analog blocks are tightly integrated with the processing and control units to provide optimal
real-time signal chain performance. The Analog-to-Digital Converter (ADC) has been enhanced with up to
40 analog channels, 22 of which have general-purpose input/output (GPIO) capability. Implementation of
oversampling is greatly simplified with hardware improvement. For safety-critical ADC conversions, a hardware
redundancy checker has been added that provides the ability to compare ADC conversion results from multiple
ADC modules for consistency without additional CPU cycles. Thirty-six frequency-independent PWMs, all with
high-resolution capability, enable control of multiple power stages, from 3-phase inverters to advanced multilevel
power topologies. The PWMs have been enhanced with Minimum Dead-Band Logic (MINDL) and Illegal Combo
Logic (ICL) features.
The inclusion of the Configurable Logic Block (CLB) allows the user to add custom logic and potentially integrate
FPGA-like functions into the C2000 real-time MCU.
An EtherCAT SubDevice Controller and other industry-standard protocols like CAN FD and USB 2.0 are
available on this device. The Fast Serial Interface (FSI) enables up to 200 Mbps of robust communications
across an isolation boundary.
As a highly connected device, the F28P65x also offers various security enablers to help designers implement
their cyber security strategy and support features like hardware encryption, secure JTAG and secure Boot.
From a safety standpoint, F28P65x supports numerous safety enablers. For more details, see Industrial
