Product details
Overview
TMS320F28P650DK8PTP from Texas Instruments is a dual-C28x DSP + CLA real-time microcontroller for high-precision power electronics control, featuring 200MHz C28x CPUs (CPU1 & CPU2), IEEE 754 double-precision FPU, 1.28MB ECC-protected flash, and 248KB parity-protected RAM. It integrates three 16-bit/12-bit ADCs (1.19MSPS @16-bit), 36 HRPWM channels (150ps resolution), EtherCAT SubDevice Controller, and dual CAN FD interfaces - deployed in servo drives, string inverters, and EV DC fast chargers.
For engineers reviewing the TMS320F28P650DK8PTP datasheet, TMS320F28P650DK8PTP pinout, TMS320F28P650DK8PTP application, or TMS320F28P650DK8PTP equivalent, key selection criteria include lockstep safety support, 176-pin HLQFP thermal performance, live firmware update (LFU) capability, and CLB-configurable logic for FPGA-replacement in motor control timing paths.
Technical Context
The TMS320F28P650DK8PTP implements a dual-C28x architecture with CPU2 operating in lockstep mode for ASIL B/SIL 2 functional safety compliance, supported by hardware MPOST, ERAD, and reciprocal ADC comparison. Its analog subsystem delivers simultaneous sampling across 40 single-ended ADC inputs with hardware oversampling (up to 128×), outlier rejection, and automatic result comparison - eliminating CPU overhead in safety-critical loop monitoring.
Control execution is distributed across CPU1 (with integrated CLA), CPU2 (lockstep), and six Configurable Logic Block (CLB) tiles enabling custom PWM generation, encoder interface logic, and dead-band enforcement without external CPLD. Communications include EtherCAT SubDevice Controller, two CAN FD controllers, FSI (200Mbps isolated data), and USB 2.0 - all synchronized to deterministic real-time scheduling via ePIE and dual 6-channel DMA.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F28P650DK9PTP | Includes EtherCAT SubDevice Controller; same 176-pin PTP package and 1.28MB flash. | Required for EtherCAT-enabled motion networks; not needed for CAN FD-only architectures. | Select DK9PTP when EtherCAT synchronization and distributed clock support are mandatory; DK8PTP reduces cost where CAN FD suffices. |
| TMS320F28379DPTP | Dual C28x+CLA at 200MHz, 1MB flash, no lockstep CPU2, no EtherCAT, 176-pin PTP package. | Targeted at non-safety-certified industrial drives; lacks ASIL B hardware validation and reciprocal ADC checking. | Choose F28379DPTP for cost-sensitive servo drives without functional safety requirements; DK8PTP adds certified lockstep and LFU for mission-critical infrastructure. |
Compared with TMS320F28P650DK9PTP, the TMS320F28P650DK8PTP removes EtherCAT but retains identical safety features and thermal packaging - making it optimal for CAN FD-based distributed motor control. Versus F28379DPTP, DK8PTP adds lockstep, MPOST, and BGCRC for systematic ASIL B compliance - essential for EV charging and industrial UPS certifications.

FAQ
What is the core configuration of the TMS320F28P650DK8PTP?
The TMS320F28P650DK8PTP integrates two 32-bit C28x DSP CPUs (CPU1 and CPU2) both running at 200MHz, plus a dedicated Control Law Accelerator (CLA) CPU also at 200MHz. CPU2 operates in lockstep mode with CPU1 for functional safety, and the CLA executes control algorithms independently - delivering 600 MIPS total processing capability. This architecture is confirmed in the Device Comparison table and Functional Block Diagram of the SPRSP69D datasheet.
Does the TMS320F28P650DK8PTP support EtherCAT?
No, the TMS320F28P650DK8PTP does not include the EtherCAT SubDevice Controller. The "DK8" variant explicitly omits EtherCAT functionality, unlike the "DK9" variant which includes it. This is documented in Table 4-1 (Device Comparison) under the EtherCAT row, where F28P650DK8 shows "No" while F28P650DK9 shows "Yes". The TMS320F28P650DK8PTP instead provides two CAN FD interfaces and FSI for high-speed isolated communication.
What package and pin count does the TMS320F28P650DK8PTP use?
The TMS320F28P650DK8PTP uses the 176-pin PowerPAD™ Thermally Enhanced Low-profile Quad Flatpack (HLQFP) package, designated by the "PTP" suffix. Its mechanical dimensions are 26mm × 26mm with 0.5mm pitch, and it includes an exposed thermal pad for efficient heat dissipation - verified in the "Device Information" section and Mechanical, Packaging, and Orderable Information (Section 11) of the SPRSP69D datasheet.
What safety certifications apply to the TMS320F28P650DK8PTP?
The TMS320F28P650DK8PTP is ISO 26262 certified up to ASIL B and IEC 61508 certified up to SIL 2 by TÜV SÜD. It implements hardware lockstep on CPU2, Memory Power-On Self-Test (MPOST), Background CRC (BGCRC), and reciprocal ADC comparison - all required for systematic capability up to ASIL D and SIL 3. These certifications and mechanisms are detailed in the Safety Peripherals section and Functional Safety documentation referenced in the datasheet.
How many ADC channels does the TMS320F28P650DK8PTP support in 176-pin PTP package?
In the 176-pin PTP package, the TMS320F28P650DK8PTP supports 36 single-ended or 18 differential ADC input channels. This is specified in Table 4-1 (Device Comparison) under "ADC Input channels (single-ended mode)" for the 176-pin PTP row. The device contains three ADC modules, each configurable for 16-bit (1.19MSPS) or 12-bit (3.92MSPS) operation, with separate sample-and-hold for simultaneous sampling.
