Product details
Overview
TMS320F28P650DK8NMRR from Texas Instruments is a dual-C28x DSP + CLA real-time microcontroller for high-precision power electronics control, featuring 200MHz C28x CPUs (CPU1 & CPU2), IEEE 754 double-precision FPU, 1.28MB ECC-protected flash, and 248KB parity-protected RAM. It delivers 1000MHz-equivalent real-time signal-chain performance and supports GaN/SiC gate driving in servo drives and solar inverters.
For engineers reviewing the TMS320F28P650DK8NMRR datasheet, TMS320F28P650DK8NMRR pinout, TMS320F28P650DK8NMRR application, or TMS320F28P650DK8NMRR equivalent, key selection criteria include lockstep safety capability, 36-channel HRPWM with 150ps resolution, EtherCAT SubDevice support, dual CAN FD interfaces, and 256-ball nFBGA (ZEJ) package compatibility.
Technical Context
The TMS320F28P650DK8NMRR implements a dual-C28x architecture with lockstep comparison on CPU2 and independent CLA execution at 200MHz, enabling functional safety up to ASIL B/SIL 2. Its analog subsystem integrates three 16-bit/12-bit ADCs (1.19MSPS @ 16-bit), 11 windowed comparators with slope-compensated DAC references, and hardware oversampling (up to 128×) with outlier rejection.
Control peripherals include 36 ePWM channels with MINDB and ICL logic for multilevel converter topologies, seven eCAP modules (two with HRCAP), six eQEP units, and 16 SDFM input channels. Communications include EtherCAT SubDevice Controller, two CAN FD controllers, USB 2.0, FSI (200Mbps), four SPI, two UART, two I²C, and PMBus-all operating under 1.2V core / 3.3V I/O voltage domains.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F28P650DK9 | Includes EtherCAT SubDevice Controller; same flash/RAM/peripherals but adds ESC block. | Required for deterministic motion control networks requiring distributed clocks and cyclic process data exchange. | Select DK9 when EtherCAT integration is mandatory; DK8 omits ESC to reduce cost and complexity where fieldbus is handled externally. |
| TMS320F28379D | Dual C28x+CLA at 200MHz, 1MB flash, no lockstep CPU2, no EtherCAT, no CAN FD; uses 176-pin HLQFP or 337-ball BGA. | Suitable for non-safety-critical industrial drives where ASIL B certification is not required. | Choose F28379D for cost-sensitive, lower-pin-count designs without functional safety or advanced networking needs. |
Compared with TMS320F28P650DK8NMRR, the DK9 variant adds EtherCAT hardware for synchronized motion networks, while the F28379D offers comparable compute but lacks lockstep, CAN FD, and safety certifications-making it appropriate only for less stringent applications.

FAQ
What is the core architecture of the TMS320F28P650DK8NMRR?
The TMS320F28P650DK8NMRR features two 32-bit C28x DSP CPUs and one Control Law Accelerator (CLA) CPU, all running at 200MHz. Each C28x includes IEEE 754 double-precision FPU, TMU, and VCRC; the CLA executes floating-point control laws independently. This architecture delivers 1000MHz-equivalent real-time signal-chain performance and supports lockstep operation on CPU2 for functional safety.
Does the TMS320F28P650DK8NMRR support functional safety standards?
Yes, the TMS320F28P650DK8NMRR is ISO 26262 certified up to ASIL B and IEC 61508 certified up to SIL 2 by TÜV SÜD. It includes lockstep CPU2 comparison, Memory Power-On Self-Test (MPOST), Hardware Built-in Self-Test (HWBIST), Embedded Real-time Analysis and Diagnostic (ERAD), and Background CRC (BGCRC) - all documented to aid system-level safety certification.
What package type does the TMS320F28P650DK8NMRR use?
The TMS320F28P650DK8NMRR uses the 256-ball New Fine Pitch Ball Grid Array (nFBGA) package with ZEJ suffix, measuring 13mm × 13mm with 0.8mm ball pitch. This package supports 185 GPIO pins, including 22 analog-capable GPIOs, and is lead-free and RoHS-compliant.
How many high-resolution PWM channels does the TMS320F28P650DK8NMRR provide?
The TMS320F28P650DK8NMRR provides 36 ePWM channels, all with 150ps high-resolution capability. These include Minimum Dead-Band Logic (MINDB) and Illegal Combo Logic (ICL) to prevent shoot-through in multilevel and resonant converters-eliminating the need for external logic in advanced power topologies.
Is EtherCAT supported on the TMS320F28P650DK8NMRR?
No, the TMS320F28P650DK8NMRR does not include the EtherCAT SubDevice Controller (ESC). That feature is present in the TMS320F28P650DK9 variant. The DK8NMRR retains all other peripherals-including dual CAN FD, USB 2.0, FSI, and PMBus-but omits ESC to optimize cost and die area for applications where EtherCAT is not required.
