Texas Instruments F280037CSPTR

Overview

F280037CSPTR from Texas Instruments is a C28x-based real-time microcontroller optimized for power electronics control, featuring a 120-MHz DSP core with IEEE 754 FPU, 256KB ECC-protected flash, 69KB ECC-protected RAM, and integrated analog peripherals including three 4-MSPS 12-bit ADCs and 16 ePWM channels (8 with 150-ps high-resolution capability). It targets motor drives, digital power converters, and EV charging modules.

For engineers reviewing the F280037CSPTR datasheet, F280037CSPTR pinout, F280037CSPTR application, or F280037CSPTR equivalent, key selection criteria include CLA acceleration support, CLB configurability, CAN FD interface availability, functional safety compliance (ASIL B/SIL 2), and LQFP-64 package compatibility with industrial temperature range (–40°C to 125°C).

Technical Context

The F280037CSPTR implements a dual-core real-time architecture: the main C28x CPU executes at 120 MHz with FPU, TMU, and VCRC extensions for fast control math, while the independent CLA runs parallel floating-point code at 120 MHz with dedicated memory and peripheral access. Its analog subsystem tightly couples three 12-bit ADCs (4 MSPS) and four CMPSS modules with 12-bit DAC references to ePWM timing units for closed-loop feedback.

Control logic is augmented by four Configurable Logic Block (CLB) tiles supporting custom state machines and position manager functions, and the Host Interface Controller (HIC) enables external host access to internal memory. The device supports Live Firmware Update with banked flash and hardware-assisted context switching to minimize downtime during field updates.

FAQ

What is the maximum operating frequency of the C28x CPU in the F280037CSPTR?

The C28x CPU in the F280037CSPTR operates at a maximum frequency of 120 MHz. This clock speed is maintained across the full industrial temperature range (–40°C to 125°C) and supports IEEE 754 single-precision floating-point instructions via the integrated FPU. The F280037CSPTR achieves deterministic real-time performance for control loops with sub-microsecond latency, making it suitable for high-switching-frequency applications such as SiC-based motor drives and digital power converters.

Does the F280037CSPTR support CAN FD communication?

Yes, the F280037CSPTR includes one MCAN (Controller Area Network with Flexible Data-Rate) module compliant with ISO 11898-1 and ISO 11898-2. It supports data phase bit rates up to 5 Mbps and payload lengths up to 64 bytes. The MCAN interface is electrically isolated from the DCAN port, allowing simultaneous legacy CAN and CAN FD communication-critical for EV charging stations interfacing with both vehicle BMS (CAN FD) and grid management systems (classical CAN).

What package type and pin count does the F280037CSPTR use?

The F280037CSPTR uses a 64-pin Low-profile Quad Flatpack (LQFP-64) package with PM suffix, measuring 12 mm × 12 mm with 0.5-mm lead pitch. This package includes an exposed thermal pad for enhanced heat dissipation and supports all core peripherals-including three ADCs, 16 ePWM channels, two CAN interfaces, and CLB logic-within a compact industrial-grade footprint suitable for space-constrained power electronics designs.

How much flash memory does the F280037CSPTR have, and is it ECC-protected?

The F280037CSPTR integrates 256KB (128KW) of on-chip flash memory, organized into two independent 128KB banks. All flash memory is protected by error-correcting code (ECC) capable of detecting and correcting single-bit errors and detecting double-bit errors. This ECC implementation meets IEC 61508 SIL 2 requirements and ensures data integrity in mission-critical power control applications subject to radiation-induced soft errors.

Is the F280037CSPTR qualified for automotive applications?

No, the F280037CSPTR is not AEC-Q100 qualified. It is rated for industrial temperature operation (–40°C to 125°C free-air) and intended for industrial, commercial, and renewable energy applications. For automotive use, Texas Instruments offers the pin-compatible F280037C-Q1 variant (PM package), which carries AEC-Q100 Grade 1 qualification and functional safety certification up to ASIL B/SIL 2-verified by TÜV SÜD.
