Product details
Overview
TMS320F28P650SK7PTP 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 36 high-resolution PWM channels (150ps). It integrates three 16-bit/12-bit ADCs (up to 3.92MSPS), 11 windowed comparators, two 12-bit DACs, EtherCAT SubDevice Controller, CAN FD, USB 2.0, and FSI for 200Mbps isolated communication - deployed in servo drives, solar string inverters, and EV on-board chargers.
For engineers reviewing the TMS320F28P650SK7PTP datasheet, TMS320F28P650SK7PTP pinout, TMS320F28P650SK7PTP application, or TMS320F28P650SK7PTP equivalent, key selection criteria include dual-CPU real-time signal chain performance, hardware safety features (ASIL B/SIL 2 certified), analog subsystem redundancy, and PTP-package thermal performance for industrial motor control designs.
Technical Context
The TMS320F28P650SK7PTP implements a single-C28x + CLA architecture (no lockstep CPU2), delivering 400 MIPS total real-time processing - optimized for deterministic control loops in power electronics. Its analog subsystem includes simultaneous sampling across three ADCs with hardware oversampling (up to 128×), automatic result comparison, and 24 redundant input channels for functional safety validation.
Control peripherals feature 36 HRPWM channels with MINDB and ICL logic, enabling direct support for matrix converters and resonant topologies without external logic. The Configurable Logic Block (6 tiles) augments ePWM/eCAP functionality and replaces external CPLD/FPGA in encoder interface and custom PWM generation.

FAQ
What is the CPU configuration of the TMS320F28P650SK7PTP?
The TMS320F28P650SK7PTP features one 200MHz C28x DSP CPU and one independent 200MHz Control Law Accelerator (CLA) CPU. Unlike dual-CPU variants (e.g., F28P650DK), it does not include a second C28x core or lockstep comparator. This configuration delivers 400 MIPS of deterministic real-time processing while optimizing cost and power for single-axis control applications. The TMS320F28P650SK7PTP maintains full peripheral compatibility with the F28P65x family.
Does the TMS320F28P650SK7PTP support EtherCAT communication?
Yes, the TMS320F28P650SK7PTP includes an integrated EtherCAT SubDevice Controller (ESC) compliant with ETG.1000 specification. It supports distributed clocks, process data mapping, and mailbox communication - enabling seamless integration into EtherCAT networks without external ASICs. The ESC operates independently of the C28x and CLA CPUs, preserving real-time determinism. The TMS320F28P650SK7PTP uses the same ESC IP block as the F28P650DK9 and F28P650SH7 variants.
What package type and thermal characteristics does the TMS320F28P650SK7PTP use?
The TMS320F28P650SK7PTP is packaged in a 176-pin PowerPAD™ Thermally Enhanced Low-profile Quad Flatpack (HLQFP, suffix PTP), measuring 26mm × 26mm with 0.5mm pitch. Its exposed thermal pad enables low junction-to-board thermal resistance (θJB = 5.2°C/W), supporting continuous operation at 125°C ambient. This package is validated for industrial and automotive under-hood applications and matches the mechanical footprint of legacy F2837xD PTP variants for drop-in layout reuse.
How many ADC channels does the TMS320F28P650SK7PTP support in single-ended mode?
The TMS320F28P650SK7PTP supports up to 36 single-ended ADC input channels when configured in the 176-pin PTP package. This count is derived from the device's pin multiplexing table and confirmed in the Device Comparison table (Table 4-1), which specifies "36" for the PTP variant under "ADC Input channels (single-ended mode)". All three integrated ADC modules (ADC-A, ADC-B, ADC-C) are fully accessible and can be synchronized for simultaneous sampling in motor phase current measurement.
Is the TMS320F28P650SK7PTP certified for functional safety standards?
Yes, the TMS320F28P650SK7PTP is ISO 26262 certified up to ASIL B and IEC 61508 certified up to SIL 2 by TÜV SÜD. Certification covers hardware integrity (ASIL B/SIL 2), systematic capability (ASIL D/SIL 3), and includes documentation for safety analysis (FMEDA, FTA). Safety features implemented in the TMS320F28P650SK7PTP include hardware CRC engines, memory built-in self-test (MBIST), reciprocal ADC comparison, and lockstep-capable peripherals - all verified per the official TI Functional Safety Documentation Package.
