Texas Instruments F280041CRSHSR

Overview

F280041CRSHSR from Texas Instruments is a 32-bit real-time microcontroller featuring a 100MHz C28x CPU with IEEE 754 single-precision FPU, Trigonometric Math Unit (TMU), and Viterbi/Complex Math Unit (VCU-I). It integrates 128KB flash, 100KB ECC-protected RAM, three 3.45MSPS 12-bit ADCs, 16 ePWM channels with 150ps resolution, and dual CAN interfaces - optimized for high-precision motor control in solar inverters and EV charging power modules.

For engineers reviewing the F280041CRSHSR datasheet, F280041CRSHSR pinout, F280041CRSHSR application, or F280041CRSHSR equivalent, key selection criteria include its 56-pin VQFN (RSH) package, CLA co-processor support, InstaSPIN-FOC™ ROM library, functional safety quality-managed status, and 125°C junction temperature rating.

Technical Context

The F280041CRSHSR implements a dual-core real-time control architecture: the main C28x CPU executes deterministic control loops at 100MHz while the independent Control Law Accelerator (CLA) runs floating-point math tasks in parallel - enabling simultaneous execution of field-oriented control (FOC) and system monitoring without CPU load penalty. Its analog subsystem includes seven programmable gain amplifiers (PGAs) with 3/6/12/24× gain settings and four SDFM input channels for isolated sigma-delta sensor interfacing.

System-level timing is managed via two internal zero-pin oscillators, windowed watchdog, and missing-clock detection. The device supports pin-bootable peripherals including two CAN ports, two SPI, two SCI, I²C, LIN, PMBus, and FSI - all multiplexed across 25 GPIO pins in the RSH package, with 12 external ADC channels and 4 PGA inputs confirmed for this variant.

FAQ

What is the maximum operating junction temperature for F280041CRSHSR?

The F280041CRSHSR is rated for a junction temperature range of –40°C to 125°C, validated per TI's SPRS945H datasheet revision March 2026. This specification applies to the RSH package variant and supports operation in high-ambient environments such as enclosed EV charging cabinets or outdoor solar enclosures without forced cooling.

Does F280041CRSHSR include the Configurable Logic Block (CLB)?

Yes, F280041CRSHSR includes the Configurable Logic Block (CLB) with four programmable logic tiles, as confirmed in TI's Device Comparison Table (Table 4-1) for F280041C variants. This enables custom logic implementation for encoder interfaces, safety interlocks, or position manager functions without external FPGA.

Is F280041CRSHSR certified for functional safety standards like ISO 26262?

No, F280041CRSHSR is designated as Functional Safety Quality-Managed (FS-QM) per TI's documentation - meaning it follows rigorous development processes but does not carry formal ISO 26262 ASIL or IEC 61508 SIL certification. Certified alternatives include F280048CPMQR and F280049CPZQR listed in Table 3-1.

How many ADC channels are accessible on the F280041CRSHSR in the RSH package?

F280041CRSHSR supports 12 external single-ended ADC input channels and 4 PGA-input channels in the 56-pin RSH package, as specified in TI's Device Comparison Table (Table 4-1) and Pin Diagram Figure 5-4. This configuration matches the analog resource allocation for RSH-packaged F280041C devices.

What communication interfaces are pin-bootable on F280041CRSHSR?

F280041CRSHSR supports pin-bootable operation for two CAN ports, one I²C interface, two SPI ports, two UART-compatible SCIs, one LIN interface, one PMBus interface, and one Fast Serial Interface (FSI), all confirmed in the "Communications Peripherals" section of the datasheet and applicable to the RSH package variant.
