Product details
Overview
F28P650DK6NMRR from Texas Instruments is a dual-CPU C28x real-time microcontroller with CLA, 200MHz operation per CPU, 1.28MB ECC-protected flash, 248KB parity-protected RAM, and integrated analog subsystem including three 16-bit/12-bit ADCs (1.19MSPS @ 16-bit), 36 HRPWM channels (150ps resolution), and two CAN FD interfaces - deployed in industrial servo drives and solar string inverters.
For engineers reviewing the F28P650DK6NMRR datasheet, F28P650DK6NMRR pinout, F28P650DK6NMRR application, or F28P650DK6NMRR equivalent, key selection criteria include lockstep CPU2 support status, ZEJ nFBGA-256 package compatibility, EtherCAT SubDevice capability, and functional safety certification level for ASIL B/SIL 2 system integration.
Technical Context
The F28P650DK6NMRR implements a dual-C28x DSP architecture with IEEE 754 double-precision FPU, TMU, and VCRC acceleration per core, plus an independent single-precision CLA CPU delivering 600 MIPS total (CPU1+CLA+CPU2). It supports live firmware update (LFU) with hardware context switching and includes dual-clock comparator (DCC), windowed watchdog, and missing clock detection for deterministic real-time control.
Analog signal chain integration includes simultaneous sampling across three ADCs with hardware oversampling (up to 128×), automatic result comparison for functional safety, and 11 windowed comparators with slope-compensated DAC references - all tightly coupled to ePWM and eCAP peripherals via dedicated crossbars for sub-microsecond latency control loops.

|---|---|---|---|
| TMS320F28379D | Single C28x+CLA subsystem (400 MIPS), 1MB flash, no EtherCAT, no CAN FD, 176-pin HLQFP only | Lacks dual-CPU lockstep and functional safety certification; limited to non-automotive industrial drives | Select when cost-sensitive designs require proven F2837x toolchain compatibility but do not need ASIL B or EtherCAT. |
| TMS320F28P550SJ | Single C28x+CLA (200MHz), 512KB flash, 169-ball NMR package, no EtherCAT, no lockstep CPU2 | Lower memory and peripheral count; targets compact motor drives where space and BOM cost are critical | Choose for space-constrained HVAC or appliance inverters where full F28P65x feature set is unnecessary. |
Compared with TMS320F28379D and TMS320F28P550SJ, F28P650DK6NMRR delivers higher computational throughput (600 vs. 400/200 MIPS), certified functional safety hardware, and advanced connectivity (EtherCAT, CAN FD, FSI), making it the only option for ASIL B-compliant, multi-axis servo systems requiring deterministic networked control.

FAQ
What is the CPU configuration of the F28P650DK6NMRR?
The F28P650DK6NMRR integrates two 32-bit C28x DSP CPUs (each running at 200MHz) and one independent Control Law Accelerator (CLA) CPU, also at 200MHz. This triple-core architecture delivers 600 MIPS total processing capability. The device supports optional lockstep operation on CPU2 for functional safety applications, and the CLA executes control law code concurrently with the C28x cores - a key capability confirmed in the official device comparison table and functional block diagram for F28P650DK6NMRR.
Does F28P650DK6NMRR support EtherCAT functionality?
F28P650DK6NMRR does not include EtherCAT SubDevice Controller functionality. While the broader F28P65x family includes EtherCAT support in select variants (e.g., F28P650DK9 and F28P650DK7), the F28P650DK6NMRR variant is explicitly listed without EtherCAT in the Device Comparison table under the "Ethernet for Control Automation Technology (EtherCAT)" row, where it shows "No" for all package options. This absence is consistent across ZEJ, NMR, PTP, and PZP packages for the DK6 suffix.
What package type and pin count does F28P650DK6NMRR use?
F28P650DK6NMRR uses the 256-ball New Fine Pitch Ball Grid Array (nFBGA) package with ZEJ suffix, measuring 13mm × 13mm with 0.8mm ball pitch. This is confirmed in the Device Information table and Mechanical, Packaging, and Orderable Information section, which lists ZEJ as the sole package option for the DK6 variant - distinguishing it from other F28P65x members that offer PTP, NMR, or PZP packages.
Is F28P650DK6NMRR qualified for automotive applications?
No, F28P650DK6NMRR is not automotive-qualified. It is rated for industrial temperature range (−40°C to +125°C ambient) and lacks the AEC-Q100 qualification denoted by the "-Q1" suffix in related parts like F28P659DK8-Q1. The device comparison table confirms no Q1 designation for F28P650DK6NMRR, and its safety certification (ISO 26262 ASIL B) applies only to industrial functional safety implementation - not full automotive-grade qualification.
What is the flash memory size and protection level of F28P650DK6NMRR?
F28P650DK6NMRR contains 1.28MB of on-chip flash memory with full ECC (Error Correction Code) protection across all 5 flash banks. This is specified in both the Device Information table and the Features section, where it states "1.28MB of CPU-mappable flash (ECC-protected) with 5 flash banks." The ECC implementation detects and corrects single-bit errors and detects multi-bit errors - a critical reliability feature for field-deployed motor control firmware stored in F28P650DK6NMRR.
