Product details
Overview
F28P659DK8ZEJRQ1 from Texas Instruments is a dual-CPU C28x real-time microcontroller with CLA, operating at 200MHz per core, featuring 1.28MB ECC-protected flash, 248KB parity-protected RAM, three 16-bit/12-bit ADCs (1.19MSPS @ 16-bit), 36 HRPWM channels (150ps resolution), and dual CAN FD interfaces - deployed in automotive HVAC compressor modules and DC fast charging stations.
For engineers reviewing the F28P659DK8ZEJRQ1 datasheet, F28P659DK8ZEJRQ1 pinout, F28P659DK8ZEJRQ1 application, or F28P659DK8ZEJRQ1 equivalent, this page delivers verified specifications, package mapping to 256-ball nFBGA (ZEJ), functional safety compliance (ISO 26262 ASIL B, IEC 61508 SIL 2), and validated alternative part selection for motor control and power conversion designs.
Technical Context
The F28P659DK8ZEJRQ1 implements lockstep operation on C28x CPU2 for functional safety, with hardware redundancy checking across ADC conversions and dual-clock comparator (DCC) for clock fault detection. Its CLA executes independent floating-point control law code at 200MHz while CPU1 and CPU2 handle real-time signal processing and system management.
It integrates EtherCAT SubDevice Controller, Fast Serial Interface (FSI) supporting 200Mbps isolated communication, and Configurable Logic Block (CLB) with six logic tiles - enabling FPGA-like custom PWM generation and encoder interface logic without external components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time motor control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F28P650DK9 | Same ZEJ package, identical dual-CPU+CLA architecture, but includes EtherCAT SubDevice Controller and lockstep mode enabled - no CLA disable option. | Targeted for EtherCAT-enabled servo drives where deterministic network synchronization is mandatory. | Select when EtherCAT integration is required and ASIL B certification is not needed. |
| TMS320F28379D | Legacy dual-core C28x+CLA at 200MHz, 1MB flash, 200KB RAM, no CAN FD or FSI - uses 176-pin HLQFP (PTP) or 337-ball BGA. | Used in cost-sensitive industrial motor drives where automotive qualification and advanced safety features are unnecessary. | Choose for non-automotive applications needing proven toolchain compatibility and lower BOM cost. |
Compared with F28P659DK8ZEJRQ1, TMS320F28P650DK9 adds EtherCAT but lacks AEC-Q100 qualification, while TMS320F28379D offers mature ecosystem support but omits CAN FD, FSI, and ISO 26262 certification - making F28P659DK8ZEJRQ1 optimal for next-gen automotive power electronics requiring both safety and connectivity.
