Product details
Overview
F280039CSPZR from Texas Instruments is a C28x-based real-time microcontroller with 120 MHz CPU, IEEE 754 FPU, CLA accelerator, 384KB ECC-protected flash, and 69KB ECC-protected RAM. It integrates three 4-MSPS 12-bit ADCs, 16 ePWM channels (8 with 150-ps resolution), dual CAN/CAN FD, FSI (200 Mbps), and CLB for FPGA-like logic extension - deployed in servo drives, solar inverters, and EV on-board chargers.
For engineers reviewing the F280039CSPZR datasheet, F280039CSPZR pinout, F280039CSPZR application, or F280039CSPZR equivalent, key selection criteria include CLA offload capability, 150-ps HRPWM timing precision, functional safety support (ASIL B/SIL 2), dual CAN FD + FSI isolation interface, and 100-pin LQFP package compatibility with industrial temperature range (–40°C to 125°C).
Technical Context
The F280039CSPZR implements a dual-core real-time control architecture: the C28x CPU executes main firmware at 120 MHz with FPU, TMU, and VCRC extensions, while the independent CLA runs parallel floating-point control loops at 120 MHz using dedicated message RAM and direct peripheral access. Both cores share ECC-protected memory resources and coordinate via hardware mailbox.
Its analog subsystem tightly couples three 4-MSPS ADCs with four CMPSS modules (each with 12-bit DAC references) and two buffered DAC outputs, enabling closed-loop current/voltage sensing and fast overvoltage trip response. The 16-channel ePWM subsystem includes integrated dead-band generation, hardware trip zones, and high-resolution capability on eight channels for GaN/SiC gate drive 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 |
|---|---|---|---|
| TMS320F280037CSPZR | 256KB flash, no CLB, same 100-pin LQFP package and peripheral set except reduced CLB and flash bank count | Lacks CLB logic extension and 128KB flash capacity; suitable for cost-sensitive servo or inverter designs without FPGA-augmented I/O | Select when CLB and full 384KB flash are not required; retains identical pinout, timing, and safety certification |
| TMS320F280049CPTFR | 128KB flash, 48-pin LQFP, no CLB, no FSI, no MCAN, but adds USB and enhanced analog (16-bit ADC option) | Smaller footprint and lower I/O count; targets compact digital power supplies and low-cost motor drives where isolation bandwidth is not critical | Choose for space-constrained designs needing USB host interface or higher-resolution ADC, accepting reduced PWM and communication flexibility |
Compared with F280039CSPZR, F280037CSPZR offers identical real-time performance and safety compliance at lower memory cost, while F280049CPTFR trades isolation bandwidth and logic extensibility for USB connectivity and smaller form factor - making each optimal for distinct subsystem-level trade-offs in power electronics architecture.
