Texas Instruments F280039CSPNR

Overview

F280039CSPNR 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 interfaces, FSI up to 200 Mbps, and CLB for FPGA-like logic extension-designed for high-frequency power electronics control in motor drives and digital power converters.

For engineers reviewing the F280039CSPNR datasheet, F280039CSPNR pinout, F280039CSPNR application, or F280039CSPNR equivalent, key selection criteria include CLA offload capability, 150-ps HRPWM timing precision, functional safety compliance (ASIL B/SIL 2), 3× ADC concurrency, and PZ-package pin compatibility with TMS320F280039C-Q1 for automotive-grade designs.

Technical Context

The F280039CSPNR implements a dual-core real-time control architecture: the C28x CPU executes deterministic floating-point control loops at 120 MHz with TMU and VCRC acceleration, while the independent CLA runs parallel math-intensive tasks (e.g., field-oriented control) using its own 120 MHz clock and dedicated message RAM. Both cores share access to ECC-protected memory and synchronized peripherals including ePWM, ADC, and CMPSS.

Its analog subsystem tightly couples three 12-bit ADCs (4 MSPS each, 250 ns conversion time) with four windowed comparators (CMPSS) featuring integrated 12-bit DAC references and digital glitch filters-enabling fast overcurrent protection and closed-loop current sensing. The 16-channel ePWM includes hardware trip zones, dead-band generation, and HRCAP on one eCAP module for precise position feedback capture.

FAQ

What is the maximum operating junction temperature for F280039CSPNR?

The F280039CSPNR has a specified junction temperature range of –40°C to 150°C. This rating applies to the PZ-package variant and enables reliable operation in high-power density applications such as onboard chargers and industrial motor drives where thermal dissipation is constrained. The device includes built-in thermal monitoring circuitry and brownout reset (BOR) to safeguard against overheating-induced failures during sustained 120 MHz operation.

Does F280039CSPNR support CAN FD communication?

Yes, F280039CSPNR includes one Controller Area Network with Flexible Data-Rate (CAN FD/MCAN) port compliant with ISO 11898-1:2015. It supports data rates up to 5 Mbps, payloads up to 64 bytes, and CRC-17 error detection-enabling high-bandwidth diagnostics and firmware updates in automotive and industrial networks. The MCAN module operates independently of the legacy DCAN port, allowing simultaneous CAN 2.0B and CAN FD communication.

How many hardware breakpoints does F280039CSPNR provide for debug?

F280039CSPNR provides ten hardware breakpoints enabled by Embedded Real-time Analysis and Diagnostic (ERAD) module. These breakpoints support complex real-time debugging scenarios-including conditional triggers on memory access, peripheral register changes, or CLA task execution-without halting CPU operation. ERAD also delivers instruction trace and system event logging, essential for validating timing-critical control loops in F280039CSPNR-based designs.

Is F280039CSPNR pin-compatible with other TMS320F28003x variants in the PZ package?

Yes, F280039CSPNR shares identical pin configuration and electrical characteristics with all TMS320F28003x devices offered in the 100-pin PZ package-including F280039C, F280039C-Q1, F280037C, and F280034. Pin mapping, peripheral signal assignments, power domains, and I/O voltage tolerances are fully aligned, enabling drop-in replacement across the family for design reuse and scalability.

What security features are implemented in F280039CSPNR?

F280039CSPNR implements dual-zone security with JTAGLOCK, zero-pin boot, and secure ROM-based boot flow. It supports encrypted firmware loading via AES accelerator and runtime integrity checks using Background CRC (BGCRC). Memory protection units enforce strict access control between secure/non-secure code regions, and DCSM (Device Configuration Security Module) prevents unauthorized read-out of flash contents-even during debug sessions-ensuring IP protection in production F280039CSPNR deployments.
