Texas Instruments F28P650SK7NMRR

Overview

TMS320F28P650SK7NMRR from Texas Instruments is a real-time C2000™ microcontroller with one 200MHz C28x DSP CPU and one 200MHz CLA co-processor, 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-frequency motor control in industrial inverters and EV charging systems.

For engineers reviewing the TMS320F28P650SK7NMRR datasheet, TMS320F28P650SK7NMRR pinout, TMS320F28P650SK7NMRR application, or TMS320F28P650SK7NMRR equivalent, key selection factors include dual-CPU architecture support, EtherCAT SubDevice Controller capability, 36-channel HRPWM with 150ps resolution, CAN FD dual interface, and functional safety certification up to ASIL B/SIL 2.

Technical Context

The TMS320F28P650SK7NMRR implements a single-C28x + CLA subsystem architecture-no lockstep CPU2-enabling deterministic real-time control without redundant core overhead. Its analog subsystem integrates three independent ADCs with hardware oversampling (up to 128×), simultaneous sampling via separate S/H, 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 HRCAP), six eQEP units, and a Configurable Logic Block (CLB) with six logic tiles for custom encoder or PWM logic-eliminating need for external FPGA in multilevel converter topologies.

FAQ

What is the CPU configuration of the TMS320F28P650SK7NMRR?

The TMS320F28P650SK7NMRR features a single 32-bit C28x DSP CPU running at 200MHz and one independent Control Law Accelerator (CLA) CPU also at 200MHz. Unlike dual-CPU variants such as TMS320F28P650DK9, it does not include a second C28x core or lockstep functionality-making it optimized for single-axis, high-performance control tasks where cost and footprint are critical. This configuration is confirmed in TI's Device Comparison table for F28P65x series.

Does the TMS320F28P650SK7NMRR support EtherCAT communication?

Yes, the TMS320F28P650SK7NMRR includes an integrated EtherCAT SubDevice Controller (ESC), enabling direct connection to EtherCAT networks without external ASICs. This capability is explicitly listed in the Device Comparison table under "Ethernet for Control Automation Technology" for the F28P650SK variant. The ESC supports standard EtherCAT frame processing and synchronization, making the TMS320F28P650SK7NMRR suitable for industrial automation nodes requiring deterministic motion control.

What package type and pin count does the TMS320F28P650SK7NMRR use?

The TMS320F28P650SK7NMRR uses a 169-ball New Fine Pitch Ball Grid Array (nFBGA) package with NMR suffix, measuring 9mm × 9mm with 0.65mm ball pitch. This is confirmed in TI's official device nomenclature documentation and Mechanical, Packaging, and Orderable Information section. The "NMRR" suffix specifically denotes the NMR package with industrial temperature grade (–40°C to 125°C).

How many ADC modules does the TMS320F28P650SK7NMRR have, and what are their key capabilities?

The TMS320F28P650SK7NMRR integrates three independent Analog-to-Digital Converters (ADCs), each configurable in 16-bit mode (1.19MSPS) or 12-bit mode (3.92MSPS). Each ADC has its own sample-and-hold circuit enabling true simultaneous sampling, hardware oversampling up to 128×, and automatic result comparison for functional safety. These capabilities are documented in the "Analog Subsystem" section and verified in Table 4-1 of the SPRSP69D datasheet.

Is the TMS320F28P650SK7NMRR certified for functional safety applications?

Yes, the TMS320F28P650SK7NMRR is ISO 26262 certified up to ASIL B and IEC 61508 certified up to SIL 2 by TÜV SÜD. It includes hardware safety mechanisms such as Memory Power-On Self-Test (MPOST), Hardware Built-in Self-Test (HWBIST), Embedded Real-time Analysis and Diagnostic (ERAD), and reciprocal ADC comparison logic-all detailed in the "Safety Peripherals" section of the datasheet. These features make the TMS320F28P650SK7NMRR suitable for safety-critical motor control and power conversion systems.
