Product details
Overview
TMS320F28P650SK6NMRR from Texas Instruments is a real-time C2000™ microcontroller with one 200MHz C28x DSP CPU and one 200MHz CLA coprocessor, 1.28MB ECC-protected flash, 248KB parity-protected RAM, and triple 16-bit/12-bit ADCs (1.19MSPS @ 16-bit). It delivers 400 MIPS total processing power for high-fidelity motor control in industrial inverters and EV charging systems.
For engineers reviewing the TMS320F28P650SK6NMRR datasheet, TMS320F28P650SK6NMRR pinout, TMS320F28P650SK6NMRR application, or TMS320F28P650SK6NMRR equivalent, key selection criteria include dual-core real-time signal chain performance, hardware safety features (ASIL B/SIL 2 certified), 36-channel HRPWM with 150ps resolution, and CAN FD + EtherCAT support for deterministic industrial networking.
Technical Context
The TMS320F28P650SK6NMRR implements a single-CPU C28x subsystem augmented by an independent CLA running at 200MHz, enabling parallel execution of control law computations without CPU intervention. Its analog subsystem integrates three ADCs with simultaneous sampling, hardware oversampling (up to 128×), and automatic result comparison for functional safety.
Control peripherals include 36 ePWM channels with Minimum Dead-Band Logic (MINDB) and Illegal Combo Logic (ICL), seven eCAP modules (two with high-resolution capture), six CLB logic tiles for FPGA-like peripheral augmentation, and dual CAN FD controllers compliant with ISO 11898-1:2015.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F28377D | Dual C28x+CLA cores (2×200MHz), 1MB flash, 337-ball BGA package | Higher pin count and dual-CPU lockstep support for ASIL D systems; lacks EtherCAT and CAN FD | Select when full lockstep redundancy and maximum analog channel count are required over industrial fieldbus integration |
| TMS320F28P550SJ | Single C28x+CLA, 512KB flash, 176-pin HTQFP, no EtherCAT or CAN FD | Lower cost, smaller footprint; targets entry-level motor drives without advanced networking | Select for cost-sensitive HVAC or pump drives where CAN FD/EtherCAT are unnecessary and flash >512KB is not required |
Compared with TMS320F28377D, the TMS320F28P650SK6NMRR trades dual-CPU lockstep for integrated EtherCAT and CAN FD-enabling deterministic motion control networks without external protocol bridges-while retaining identical CLA acceleration and ADC oversampling capabilities for power electronics signal chains.

FAQ
What is the core configuration of the TMS320F28P650SK6NMRR?
The TMS320F28P650SK6NMRR contains one 32-bit C28x DSP CPU and one Control Law Accelerator (CLA) coprocessor, both operating at 200MHz. It does not include a second C28x CPU. This single-CPU + CLA architecture balances high-performance real-time control with reduced complexity and cost versus dual-CPU variants like the F28P650DK. The CLA executes control law code independently, offloading the C28x for higher system throughput.
Does the TMS320F28P650SK6NMRR support EtherCAT functionality?
Yes, the TMS320F28P650SK6NMRR includes a dedicated EtherCAT SubDevice Controller (ESC) compliant with ETG.1000.3 specification. This hardware block handles frame processing, mailbox communication, and distributed clock synchronization without consuming C28x or CLA resources, enabling deterministic motion control network integration in servo drives and robotics applications.
What package and pin count does the TMS320F28P650SK6NMRR use?
The TMS320F28P650SK6NMRR uses a 169-ball New Fine Pitch Ball Grid Array (nFBGA) package with 9mm × 9mm footprint and 0.65mm ball pitch. It provides 119 general-purpose I/O pins (excluding JTAG and oscillator pins), including 21 analog-capable GPIOs, supporting dense PCB layouts for space-constrained power electronics modules.
How does the safety certification of the TMS320F28P650SK6NMRR compare to automotive-grade variants?
The TMS320F28P650SK6NMRR is certified to ISO 26262 ASIL B and IEC 61508 SIL 2 by TÜV SÜD. Unlike Q1-qualified parts (e.g., F28P659DK-Q1), it is not AEC-Q100 qualified and lacks automotive-specific qualification testing. Its safety mechanisms-including MPOST, HWBIST, and ERAD-are identical, but automotive use requires validation under AEC-Q100 stress conditions and temperature range extension to 150°C junction.
What ADC configurations are supported on the TMS320F28P650SK6NMRR?
The TMS320F28P650SK6NMRR integrates three independent 16-bit/12-bit ADCs. Each supports 16-bit mode at 1.19MSPS (840ns conversion time) or 12-bit mode at 3.92MSPS (255ns). With 40 single-ended or 19 differential input channels per ADC and separate sample-and-hold circuits, it enables simultaneous sampling across multiple current/voltage sensors in three-phase systems.
