Overview
TMS320F28P650DK7PTP from Texas Instruments is a dual-CPU C28x real-time microcontroller with CLA, 200MHz operation, 1.28MB ECC-protected flash, 248KB parity-protected RAM, and 36 HRPWM channels - deployed in servo drives, solar string inverters, and EV on-board chargers for deterministic control of SiC/GaN power stages.
For engineers reviewing the TMS320F28P650DK7PTP datasheet, TMS320F28P650DK7PTP pinout, TMS320F28P650DK7PTP application, or TMS320F28P650DK7PTP equivalent, key selection criteria include lockstep CPU2 support, EtherCAT SubDevice capability, dual CAN FD interfaces, hardware ADC redundancy for functional safety, and PTP-package thermal performance in industrial motor control designs.
Technical Context
The TMS320F28P650DK7PTP integrates two independent 200MHz C28x DSP cores (CPU1 + CPU2) with IEEE 754 double-precision FPU, TMU, and VCRC, plus a dedicated 200MHz CLA for parallel control-law execution - enabling simultaneous real-time current loop (CPU1), position loop (CPU2), and observer computation (CLA) without CPU contention.
Its analog subsystem includes three 16-bit/12-bit ADCs (1.19 MSPS @ 16-bit), 11 windowed comparators with slope-compensated DAC references, and hardware oversampling (up to 128×) with outlier rejection - tightly coupled to 36 HRPWM channels featuring MINDB and ICL logic for multilevel converter gate drive timing integrity.

FAQ
What is the core configuration of the TMS320F28P650DK7PTP?
The TMS320F28P650DK7PTP features two independent 32-bit C28x DSP CPUs (CPU1 and CPU2) and one Control Law Accelerator (CLA), all operating at 200MHz. CPU2 supports lockstep mode for functional safety, and the CLA executes control algorithms in parallel - delivering 600 MIPS total deterministic processing. This architecture is implemented in the TMS320F28P650DK7PTP to meet tight timing constraints in servo and inverter applications.
Does the TMS320F28P650DK7PTP support EtherCAT functionality?
The TMS320F28P650DK7PTP does not include the EtherCAT SubDevice Controller - that feature is enabled only in variants with suffix "DK9" (e.g., TMS320F28P650DK9PTP). The TMS320F28P650DK7PTP retains all other peripherals including dual CAN FD, USB 2.0, and FSI, making it suitable for applications where EtherCAT is not required but high-speed deterministic control is essential. This distinction is explicitly defined in TI's device comparison table for the F28P65x family.
What package type and thermal characteristics does the TMS320F28P650DK7PTP use?
The TMS320F28P650DK7PTP uses the 176-pin PowerPAD™ Thermally Enhanced Low-Profile Quad Flatpack (HLQFP), designated by suffix "PTP", with 26mm × 26mm footprint and 0.5mm pitch. Its thermal resistance (θJA) is 22.5°C/W under JEDEC standard conditions, enabling reliable operation at 125°C ambient in motor drive and power conversion applications. This package is validated for the TMS320F28P650DK7PTP in TI's SPRSP69D datasheet Section 6.8.
How many ADC channels and what resolution modes does the TMS320F28P650DK7PTP support?
The TMS320F28P650DK7PTP integrates three configurable Analog-to-Digital Converters (ADCs), each supporting both 16-bit (1.19 MSPS) and 12-bit (3.92 MSPS) modes. It provides up to 40 single-ended or 19 differential input channels, with separate sample-and-hold circuits per ADC for true simultaneous sampling - critical for vector control in 3-phase motor drives. These specifications are confirmed in the TMS320F28P650DK7PTP device comparison table and Section 6.13 of the datasheet.
Is the TMS320F28P650DK7PTP qualified for automotive applications?
No, the TMS320F28P650DK7PTP is an industrial-grade device rated for –40°C to 125°C ambient temperature and is not AEC-Q100 qualified. Automotive variants carry the "-Q1" suffix (e.g., TMS320F28P659DK8-Q1) and undergo additional qualification testing. The TMS320F28P650DK7PTP is intended for industrial motor control, solar inverters, and EV charging infrastructure where extended temperature range and functional safety certification (ISO 26262 ASIL B) are not mandated.
