Product details
Overview
TMS320F28P650DK9PTP from Texas Instruments is a dual-C28x DSP + CLA real-time microcontroller in 176-pin HLQFP (PTP) package, delivering 600 MIPS total processing (2×200MHz C28x + 200MHz CLA), 1.28MB ECC-protected flash, and 248KB parity-protected RAM for high-fidelity motor control in industrial inverters and EV charging systems.
For engineers reviewing the TMS320F28P650DK9PTP datasheet, TMS320F28P650DK9PTP pinout, TMS320F28P650DK9PTP application, or TMS320F28P650DK9PTP equivalent, key selection criteria include dual-lockstep CPU safety support, 36-channel HRPWM with 150ps resolution, EtherCAT SubDevice capability, and integrated analog subsystem with triple 16-bit/1.19MSPS ADCs.
Technical Context
The TMS320F28P650DK9PTP implements a deterministic real-time control architecture with two independent 200MHz C28x DSP cores (CPU1 and CPU2) operating in lockstep mode for functional safety, plus a dedicated 200MHz CLA CPU executing control law code in parallel-enabling simultaneous current/voltage loop execution without CPU intervention.
Its analog subsystem integrates three 16-bit/1.19MSPS ADCs with hardware oversampling (up to 128×), redundant input channels, and automatic result comparison; combined with 11 windowed comparators, two 12-bit DACs, and 36 HRPWM channels featuring MINDB and ICL logic, it targets GaN/SiC-based power conversion requiring sub-nanosecond timing precision and hardware-level fault response.
