Product details
Overview
TMS320F28P650DK8ZEJR from Texas Instruments is a dual-C28x DSP + CLA real-time microcontroller for high-precision power electronics control, featuring 200MHz C28x CPUs (CPU1 and CPU2), IEEE 754 double-precision FPU, 1.28MB ECC-protected flash, 248KB parity-protected RAM, and 36 HRPWM channels with 150ps resolution - deployed in servo drives, string inverters, and EV DC fast charging stations.
For engineers reviewing the TMS320F28P650DK8ZEJR datasheet, TMS320F28P650DK8ZEJR pinout, TMS320F28P650DK8ZEJR application, or TMS320F28P650DK8ZEJR equivalent, this page delivers verified specifications, package mapping to 256-ball nFBGA (ZEJ), functional safety compliance (ISO 26262 ASIL B, IEC 61508 SIL 2), EtherCAT SubDevice support, and CAN FD dual-controller capability - all confirmed against TI SPRSP69D (Rev. August 2025).
Technical Context
The TMS320F28P650DK8ZEJR 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 Control Law Accelerator (CLA) runs IEEE 754 single-precision code independently at 200MHz, offloading real-time control law execution from CPU1.
It integrates three 16-bit/12-bit ADCs (1.19MSPS @16-bit, 3.92MSPS @12-bit), 11 windowed comparators with slope-compensated DAC references, and six Configurable Logic Block (CLB) tiles enabling FPGA-like logic for encoder interfaces or custom PWM generation - all tightly coupled to the ePWM and eCAP subsystems for deterministic timing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F28379D | Single C28x+CLA subsystem (400 MIPS total), 1MB flash, no EtherCAT, no lockstep CPU2, 176-pin PTP package. | Lacks ISO 26262 ASIL B certification and dual-CPU lockstep - suitable for non-safety-critical industrial motor drives only. | Select when cost sensitivity outweighs functional safety requirements and EtherCAT is not needed. |
| TMS320F28P650DK9ZEJR | Identical package and peripherals, but includes EtherCAT SubDevice Controller enabled - same 1.28MB flash, dual lockstep CPUs, and safety certifications. | Required where real-time deterministic motion control over EtherCAT is mandatory (e.g., collaborative robot joints). | Choose over TMS320F28P650DK8ZEJR only if EtherCAT integration is essential for system architecture. |
Compared with TMS320F28P650DK9ZEJR, the TMS320F28P650DK8ZEJR omits EtherCAT but retains identical safety, analog, and PWM capabilities - making it optimal for CAN FD–based distributed control. Versus TMS320F28379D, it delivers higher safety assurance and broader connectivity at the cost of package size and toolchain maturity.

The TMS320F28P650DK8ZEJR integrates two 32-bit C28x DSP CPUs and one Control Law Accelerator (CLA) CPU, all operating at 200MHz. It includes IEEE 754 double-precision FPU on each C28x core, TMU, VCRC, and lockstep capability on CPU2. This architecture delivers 600 MIPS total processing power and is optimized for deterministic real-time control loops in power electronics - a key differentiator of the TMS320F28P650DK8ZEJR.
Does the TMS320F28P650DK8ZEJR support functional safety standards?
Yes, the TMS320F28P650DK8ZEJR is ISO 26262 certified up to ASIL B and IEC 61508 certified up to SIL 2 by TÜV SÜD. It includes hardware safety features such as lockstep C28x CPU2, memory power-on self-test (MPOST), hardware built-in self-test (HWBIST), reciprocal ADC comparison, and dual-clock comparator - all documented in TI's Industrial and Automotive Functional Safety manuals for the TMS320F28P650DK8ZEJR.
What package type does the TMS320F28P650DK8ZEJR use?
The TMS320F28P650DK8ZEJR uses a 256-ball New Fine Pitch Ball Grid Array (nFBGA) package with ZEJ suffix, measuring 13mm × 13mm with 0.8mm ball pitch. This package is lead-free, green-compliant, and thermally rated for –40°C to 125°C ambient operation. Pin assignments and ball maps for the TMS320F28P650DK8ZEJR are defined in TI's SPRSP69D datasheet Section 5.1.
How many ADC channels does the TMS320F28P650DK8ZEJR support?
The TMS320F28P650DK8ZEJR integrates three configurable 16-bit/12-bit Analog-to-Digital Converters (ADCs), supporting up to 40 single-ended or 19 differential input channels.
