Product details
Overview
TMS320F28P659DK8ZEJQ1 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, 248KB parity-protected RAM, and automotive-grade AEC-Q100 qualification (–40°C to 125°C). It delivers 600 MIPS total processing power and supports safety-critical motor drives with lockstep CPU2 and ISO 26262 ASIL B certification.
For engineers reviewing the TMS320F28P659DK8ZEJQ1 datasheet, TMS320F28P659DK8ZEJQ1 pinout, TMS320F28P659DK8ZEJQ1 application, or TMS320F28P659DK8ZEJQ1 equivalent, key selection considerations include its 256-ball nFBGA (ZEJ) package, dual CAN FD interfaces, EtherCAT SubDevice Controller, 36-channel HRPWM with 150ps resolution, and integrated analog subsystem with three 16-bit/1.19MSPS ADCs.
Technical Context
The TMS320F28P659DK8ZEJQ1 implements a deterministic real-time control architecture with two independent 200MHz C28x DSP cores (CPU1 and CPU2), where CPU2 operates in lockstep mode for functional safety compliance. Its Control Law Accelerator (CLA) runs at 200MHz with IEEE 754 single-precision FPU, executing control loops independently of the C28x cores.
Hardware acceleration includes Trigonometric Math Unit (TMU), Fast Integer Division (FINTDIV), VCRC engine, and dedicated peripherals: 36 HRPWM channels with MINDB/ICL logic, seven eCAP modules (two with HRCAP), six eQEP, 16 SDFM inputs, and Configurable Logic Block (CLB) with six logic tiles for custom PWM or encoder interface logic.
