Texas Instruments F28P650SH7PTP

Overview

TMS320F28P650SH7PTP from Texas Instruments is a real-time C2000™ microcontroller with one 32-bit C28x CPU and one CLA CPU, both operating at 200 MHz, 768 KB of ECC-protected flash, 244 KB RAM, and 176-pin HLQFP (PTP) package rated for –40°C to 125°C operation. It integrates three 16-bit/12-bit ADCs (up to 3.92 MSPS), 36 HRPWM channels (150 ps resolution), EtherCAT SubDevice Controller, dual CAN FD, and Configurable Logic Block (CLB) for power electronics control in industrial motor drives and solar inverters.

For engineers reviewing the TMS320F28P650SH7PTP datasheet, TMS320F28P650SH7PTP pinout, TMS320F28P650SH7PTP application, or TMS320F28P650SH7PTP equivalent, key selection criteria include single-CPU+CLA architecture, PTP package thermal performance, EtherCAT slave capability, hardware safety features (ERAD, BGCRC), and CLB-based FPGA-like logic augmentation without external components.

Technical Context

The TMS320F28P650SH7PTP implements a deterministic real-time control subsystem where the C28x CPU executes floating-point control loops using IEEE 754 double-precision FPU, TMU, and VCRC acceleration, while the independent CLA handles background tasks like PWM update or ADC post-processing. Its analog subsystem delivers simultaneous sampling across three ADCs with hardware oversampling (up to 128×), redundant comparison, and 11 windowed comparators with slope-compensated DAC references.

Control peripherals include 36 ePWM channels with Minimum Dead-Band Logic (MINDB) and Illegal Combo Logic (ICL) for multilevel converter topologies, six eQEP modules, 16 SDFM inputs, and seven eCAP modules (two with high-resolution capture). Communications support includes EtherCAT SubDevice Controller, two CAN FD interfaces, USB 2.0, FSI (200 Mbps), four SPI, two I²C, and two LIN/SCI UARTs - all synchronized via shared crossbar routing.

FAQ

What is the CPU configuration of the TMS320F28P650SH7PTP?

The TMS320F28P650SH7PTP contains 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 functionality. This configuration balances performance and cost for single-axis motor control and digital power applications where full redundancy is not required. The TMS320F28P650SH7PTP uses the CLA to offload time-critical computations such as PWM update or ADC post-processing from the main C28x core.

Does the TMS320F28P650SH7PTP support EtherCAT?

No, the TMS320F28P650SH7PTP does not include the EtherCAT SubDevice Controller. EtherCAT capability is only present in select F28P65x variants with "DK" or "SK" suffixes (e.g., F28P650DK9, F28P650SK7) and requires the ZEJ or NMR package options. The TMS320F28P650SH7PTP retains all other communications peripherals - including two CAN FD interfaces, USB 2.0, FSI, and multiple SPI/I²C/SCI ports - making it suitable for non-EtherCAT industrial networks such as CANopen or proprietary high-speed serial protocols.

What package and thermal characteristics does the TMS320F28P650SH7PTP use?

The TMS320F28P650SH7PTP uses the 176-pin PowerPAD™ Thermally Enhanced Low-Profile Quad Flatpack (HLQFP), designated by the "PTP" suffix, with dimensions of 26 mm × 26 mm and 0.5 mm pitch. It features an exposed thermal pad for direct PCB copper pour attachment, delivering low junction-to-board thermal resistance (θ_JB = 5.5°C/W per TI documentation). This package supports continuous operation from –40°C to 125°C ambient, validated for industrial motor drive and solar inverter applications with high power density and limited airflow.

How many ADC channels are accessible on the TMS320F28P650SH7PTP?

The TMS320F28P650SH7PTP provides access to 36 single-ended or 18 differential analog input channels across its three integrated 16-bit/12-bit ADCs. This count is specific to the 176-pin PTP package; higher pin-count packages (e.g., ZEJ) support up to 40 single-ended inputs. All ADCs support simultaneous sampling, hardware oversampling (up to 128×), and automatic result comparison - critical for functional safety compliance in motor current sensing and DC-link voltage monitoring within the TMS320F28P650SH7PTP-based designs.

Is the TMS320F28P650SH7PTP certified for functional safety standards?

Yes, the TMS320F28P650SH7PTP is part of the ISO 26262 ASIL B and IEC 61508 SIL 2 certified F28P65x family. Certification applies to the device's safety mechanisms - including ERAD, BGCRC, memory built-in self-test (MPOST), and hardware redundancy checkers - and is supported by TI's Functional Safety Documentation Package. While the TMS320F28P650SH7PTP itself is not individually listed in TÜV SÜD certificates (which cover the broader F28P65x family), its identical safety architecture and qualification testing ensure compliance when implemented per TI's safety manual guidelines.
