Product details
Overview
F280049RSHSR from Texas Instruments is a 100MHz C28x-based real-time MCU with IEEE 754 FPU, CLA accelerator, 256KB flash, 100KB RAM, and integrated analog subsystem including three 3.45MSPS 12-bit ADCs - deployed in EV charging power modules and solar string inverters for high-precision closed-loop control.
For engineers reviewing the F280049RSHSR datasheet, F280049RSHSR pinout, F280049RSHSR application, or F280049RSHSR equivalent, key selection criteria include 16-channel ePWM with 150ps resolution, dual CAN interfaces, functional safety documentation up to ASIL B, and RSH package-specific GPIO count (25 pins) and analog input count (12 channels).
Technical Context
The F280049RSHSR implements a dual-core real-time control architecture: the 100MHz C28x CPU executes main control loops with TMU/VCU-I acceleration for trigonometric and complex math, while the independent 100MHz CLA handles time-critical tasks like PWM update and current loop computation without CPU intervention.
Its analog front end integrates seven PGAs (gain settings 3/6/12/24), seven windowed comparators with 12-bit DAC references, two buffered DAC outputs, and four SDFM input channels - enabling direct sigma-delta modulator interfacing across isolation barriers for motor phase current sensing.
Key Specifications

|---|---|
| CPU Core | C28x 32-bit, 100MHz - delivers deterministic real-time execution for motor control and digital power algorithms. |
| Floating-Point Unit | IEEE 754 single-precision FPU - enables high-accuracy field-oriented control (FOC) without fixed-point scaling overhead. |
| Control Law Accelerator | Independent 100MHz CLA with FPU support - offloads PWM update, PID, and observer calculations from main CPU. |
| Flash / RAM | 256KB ECC-protected flash (dual-bank), 100KB ECC/parity-protected RAM - supports concurrent execute-and-program and robust runtime data integrity. |
| Analog Subsystem | Three 12-bit ADCs @ 3.45MSPS, 12 external channels, 4 PPBs per ADC, 7 PGAs, 7 CMPSS - enables multi-sensor acquisition and fast overcurrent trip response. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F280049CPZQR | 100-pin LQFP, automotive-qualified (AEC Q100 Grade 1), same core/peripherals but higher GPIO count (40) and ADC channels (21). | Preferred for automotive traction inverters requiring extended temperature range and qualification evidence. | Select when board layout allows larger package and automotive compliance is mandatory; not drop-in due to pinout and thermal pad differences. |
| TMS320F280041CRSHR | Same RSH package, but 128KB flash, no CLA, no CLB, and only 128KB flash - lacks InstaSPIN-FOC ROM and hardware accelerators. | Suitable for cost-sensitive, lower-performance AC drive control where sensorless FOC is not required. | Choose for simplified designs with reduced memory and compute needs; software FOC possible but increases CPU load and latency. |
Compared with F280049RSHSR, the F280049CPZQR offers greater I/O and analog channel density for complex systems, while the F280041CRSHR trades accelerators and flash for lower BOM cost - making F280049RSHSR optimal for space-constrained, high-fidelity power conversion where CLA and CLB are essential.

FAQ
What is the maximum operating frequency of the F280049RSHSR CPU core?
The F280049RSHSR features a TMS320C28x 32-bit CPU core rated at 100MHz - delivering deterministic real-time performance for demanding control algorithms such as field-oriented control and digital power regulation. This frequency is maintained across the full industrial temperature range (–40°C to 125°C) under specified supply conditions.
Does the F280049RSHSR include hardware support for functional safety standards?
Yes, the F280049RSHSR is developed for functional safety applications with hardware integrity up to ASIL B and systematic capability up to ASIL D. TI provides a Functional Safety Manual and TÜV SÜD certification documentation - though formal ASIL B certification applies to specific automotive-qualified variants (e.g., F280049C-Q1), not the RSHSR commercial-grade part.
How many analog input channels are accessible on the F280049RSHSR in the 56-pin RSH package?
The F280049RSHSR supports 12 external analog input channels in the 56-pin VQFN (RSH) package - derived from its three integrated 12-bit ADCs. These channels are routed through dedicated AIO pins (AIO0–AIO11) and may be sourced directly or via the seven integrated programmable gain amplifiers (PGAs).
What communication interfaces does the F280049RSHSR support for industrial networking?
The F280049RSHSR integrates two Controller Area Network (CAN) 2.0B ports, two UART-compatible SCI interfaces, two SPI ports, one I²C interface, one PMBus interface, one LIN interface, and one Fast Serial Interface (FSI). These support industrial networking protocols including CANopen, Modbus RTU over SCI, and proprietary isolated command links via FSI.
Is the InstaSPIN-FOC™ library included in the F280049RSHSR?
No - the InstaSPIN-FOC™ library is only present in 'C'-suffix variants (e.g., F280049C, F280049C-Q1). The F280049RSHSR lacks the secure ROM containing this certified sensorless FOC engine. Developers must implement FOC in flash or use external libraries, as the base F280049RSHSR does not include preloaded motor control firmware.
