Overview
TMS320F28P650SK6PTP from Texas Instruments is a real-time C2000™ microcontroller with one 32-bit C28x CPU and one CLA CPU, both operating at 200 MHz, 1.28MB ECC-protected flash, 248KB parity-protected RAM, and 36 high-resolution PWM channels (150ps resolution). It integrates three 16-bit/12-bit ADCs (up to 3.92 MSPS), 11 windowed comparators, two 12-bit DACs, EtherCAT SubDevice Controller, dual CAN FD, and FSI up to 200 Mbps - deployed in servo drives, solar string inverters, and EV on-board chargers.
For engineers reviewing the TMS320F28P650SK6PTP datasheet, TMS320F28P650SK6PTP pinout, TMS320F28P650SK6PTP application, or TMS320F28P650SK6PTP equivalent, key selection criteria include single-CPU+CLA architecture, PTP (HLQFP-176) package with 106 GPIO, industrial temperature range (–40°C to 125°C), and functional safety support up to ASIL B/SIL 2.
Technical Context
The TMS320F28P650SK6PTP implements a deterministic real-time control subsystem centered on a single C28x DSP core (200 MHz) augmented by an independent CLA CPU (200 MHz), delivering 400 MIPS total signal-processing throughput. Its analog subsystem features hardware oversampling (up to 128×), automatic ADC result comparison for functional safety, and slope-compensated DACs enabling peak/valley current mode control.
Control peripherals include 36 HRPWM channels with Minimum Dead-Band Logic (MINDB) and Illegal Combo Logic (ICL), seven eCAP modules (two with HRCAP), six eQEP modules, and a Configurable Logic Block (6 tiles) for FPGA-like logic offload. Communications include EtherCAT SubDevice Controller, dual CAN FD, USB 2.0, FSI (200 Mbps), and PMBus-compatible I²C.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F28377D | Dual C28x+CLA CPUs (2×200 MHz), 1MB flash, 337-ball BGA - higher compute density but no EtherCAT SubDevice Controller. | Better suited for multi-axis CNC or traction inverter where lockstep redundancy and dual CPU coordination are required. | Select TMS320F28377D when dual-CPU lockstep safety or >1.28MB flash is mandatory; avoid if EtherCAT integration or HLQFP packaging is essential. |
| TMS320F28P550SJ6PTP | Single C28x+CLA, 512KB flash, 176-pin PTP package, same peripheral set minus EtherCAT and second CAN FD - lower cost, reduced feature set. | Targeted at cost-sensitive industrial motor drives where EtherCAT is not required and flash demand is <1MB. | Select TMS320F28P550SJ6PTP for simplified BOMs in non-networked motor control; retain TMS320F28P650SK6PTP when EtherCAT, dual CAN FD, or 1.28MB flash are design-critical. |
Compared with TMS320F28377D, TMS320F28P650SK6PTP trades dual-CPU lockstep for integrated EtherCAT and smaller HLQFP footprint; compared with TMS320F28P550SJ6PTP, it adds 768KB flash, EtherCAT, and second CAN FD - making it optimal for networked, high-fidelity power conversion where firmware scalability and deterministic networking are prioritized.

FAQ
What is the CPU configuration of the TMS320F28P650SK6PTP?
The TMS320F28P650SK6PTP features one 32-bit C28x DSP CPU and one Control Law Accelerator (CLA) CPU, both running at 200 MHz. Unlike dual-CPU variants (e.g., F28P650DK), it does not include a second C28x core or lockstep capability - making it optimized for cost-sensitive, single-loop high-performance control applications where CLA offload suffices.
Does the TMS320F28P650SK6PTP support EtherCAT communication?
Yes, the TMS320F28P650SK6PTP includes a fully integrated EtherCAT SubDevice Controller (ESC) compliant with ETG.1000.3 specification. This enables deterministic, sub-microsecond jitter communication in synchronized multi-axis motion control systems without external ASICs - a key differentiator versus non-EtherCAT C2000 variants like the F28P550 series.
What package type and thermal characteristics does the TMS320F28P650SK6PTP use?
The TMS320F28P650SK6PTP uses the 176-pin PowerPAD™ Thermally Enhanced Low-profile Quad Flatpack (HLQFP, suffix PTP), measuring 26mm × 26mm with 0.5mm pitch and an exposed thermal pad. Its thermal resistance (θJA) is 22.5°C/W, enabling reliable operation at full load in industrial motor drive enclosures up to 85°C ambient without forced air.
How many high-resolution PWM channels does the TMS320F28P650SK6PTP provide?
The TMS320F28P650SK6PTP provides 36 ePWM channels, all supporting 150ps high-resolution timing. Each channel includes hardware features such as Minimum Dead-Band Logic (MINDB) and Illegal Combo Logic (ICL), allowing safe, autonomous control of advanced topologies including multilevel inverters, matrix converters, and resonant LLC stages without CPU intervention.
Is the TMS320F28P650SK6PTP qualified for automotive applications?
No - the TMS320F28P650SK6PTP is rated for industrial temperature range (–40°C to 125°C) and carries no AEC-Q100 qualification. For automotive use, TI offers the pin-compatible TMS320F28P659SH6-Q1 variant, which is AEC-Q100 Grade 1 qualified (–40°C to 125°C) and certified to ISO 26262 ASIL B. The TMS320F28P650SK6PTP remains ideal for industrial, solar, and EV charging infrastructure.
