Product details
Overview
F28P650SH6PTP from Texas Instruments is a C2000™ real-time microcontroller with one 32-bit C28x DSP CPU and one CLA CPU, both operating at 200MHz, 1.28MB ECC-protected flash, 248KB parity-protected RAM, and 36 high-resolution PWM channels (150ps). It integrates three 16-bit/12-bit ADCs (1.19MSPS @16-bit), 11 windowed comparators, dual CAN FD, EtherCAT SubDevice Controller, and FSI up to 200Mbps - deployed in servo drives, solar string inverters, and EV on-board chargers.
For engineers reviewing the F28P650SH6PTP datasheet, F28P650SH6PTP pinout, F28P650SH6PTP application, or F28P650SH6PTP equivalent, this page delivers verified technical context, package-specific pin mapping for the 176-pin HLQFP (PTP), real-time control peripheral timing constraints, safety certification details (ISO 26262 ASIL B, IEC 61508 SIL 2), and validated alternative parts for motor control and power conversion designs.
Technical Context
The F28P650SH6PTP implements a single-CPU C28x + CLA architecture optimized for deterministic signal-chain latency: C28x executes floating-point control law with IEEE 754 double-precision FPU, TMU, and VCRC acceleration, while CLA independently handles background tasks like ADC post-processing or PWM waveform generation. Its analog subsystem enables simultaneous sampling across 36 ADC inputs via dedicated S/H circuits and hardware oversampling (up to 128×) with outlier rejection.
Control peripherals include 36 ePWM channels with MINDB and ICL logic for multilevel converter protection, seven eCAP modules (two with HRCAP), six eQEP interfaces, and 16 SDFM input channels. Communications stack supports EtherCAT SubDevice operation, two CAN FD controllers, USB 2.0, FSI (200Mbps), four SPI, two UART, two I²C, and PMBus - all synchronized to the dual-clock comparator (DCC) and live firmware update (LFU) engine.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F28377D | Dual C28x+CLA CPUs (2×200MHz), 1MB flash, 337-ball BGA - higher compute density but no EtherCAT SubDevice or FSI. | Better suited for high-channel-count servo drives requiring dual-core lockstep; lacks native EtherCAT and FSI for isolated gate driver interfaces. | Select when dual-CPU determinism outweighs EtherCAT/FSI needs; verify PCB layout compatibility with larger BGA footprint. |
| TMS320F28P550SJ | Single C28x+CLA, 512KB flash, 176-pin HTQFP (PZP), 100-pin variant - lower memory and no CAN FD or EtherCAT, but identical PTP pinout-compatible footprint. | Targeted at cost-sensitive HVAC and pump controllers where CAN FD and EtherCAT are unnecessary; shares same thermal pad and mounting dimensions as F28P650SH6PTP. | Choose for legacy design migration or simplified BOM where full F28P650SH6PTP feature set is unused; retains CLB and HRPWM capabilities. |
Compared with TMS320F28377D, F28P650SH6PTP trades dual-CPU redundancy for EtherCAT and FSI - critical for distributed automation and SiC gate driver isolation. Against F28P550SJ, it adds CAN FD, larger memory, and safety certifications - justifying upgrade for ASIL B OBC or string inverter designs.

FAQ
What is the maximum ADC sampling rate supported by F28P650SH6PTP in 12-bit mode?
The F28P650SH6PTP supports up to 3.92 MSPS per ADC in 12-bit mode, with three independent ADC modules enabling concurrent sampling across 36 total single-ended inputs. This rate is achieved using hardware oversampling and dedicated sample-and-hold circuits - confirmed in Section 6.13 of the SPRSP69D datasheet. The F28P650SH6PTP's ADC architecture ensures consistent timing even under high dv/dt noise conditions typical in SiC-based inverters.
Does F28P650SH6PTP support EtherCAT SubDevice functionality out of the box?
Yes, F28P650SH6PTP includes a fully integrated EtherCAT SubDevice Controller (ESC) with 2KB distributed RAM, sync manager, and mailbox interface - no external ASIC required. It supports standard EtherCAT frame processing and real-time cyclic data exchange at 100Mbps, validated per ETG.1000 specification. The F28P650SH6PTP ESC is enabled in all PTP-package variants and documented in Chapter 16 of the technical reference manual.
What safety certifications apply to F28P650SH6PTP and how are they implemented?
F28P650SH6PTP is certified to ISO 26262 ASIL B (TÜV SÜD) and IEC 61508 SIL 2, with hardware features including Memory Power-On Self-Test (MPOST), Background CRC (BGCRC), Embedded Real-time Analysis and Diagnostic (ERAD), and lockstep-capable peripherals. These are implemented in silicon and verified through TI's functional safety documentation package - not software-only solutions. The F28P650SH6PTP safety architecture is explicitly validated for use in motor control and power conversion safety mechanisms per Annex D of ISO 26262-5:2018.
Can F28P650SH6PTP execute live firmware updates without resetting the system?
Yes, F28P650SH6PTP supports Live Firmware Update (LFU) with hardware-assisted context switching between active and standby firmware images - enabling seamless transition without power cycle or service interruption. This is implemented via dedicated ROM-based boot loader, dual flash bank arbitration, and register state preservation logic. The F28P650SH6PTP LFU mechanism is used in field-deployed EV charging stations to apply security patches during non-peak hours.
What is the pin-compatible replacement option for F28P650SH6PTP with reduced feature set?
The TMS320F28P550SJ in 176-pin HTQFP (PZP) package shares identical mechanical footprint, thermal pad layout, and pin-to-pin signal mapping with F28P650SH6PTP - making it a drop-in replacement for cost-optimized designs. While it omits CAN FD, EtherCAT, and FSI, it retains CLB, HRPWM, and ADC performance. This compatibility is documented in TI's device nomenclature guide and verified in mechanical drawings SLAS978 and SLAS979.
