Product details
Overview
F280049CPMSR from Texas Instruments is a 32-bit real-time microcontroller (MCU) with 100MHz C28x CPU, IEEE 754 single-precision FPU, CLA accelerator, 256KB ECC-protected flash, and 100KB RAM. It integrates three 3.45MSPS 12-bit ADCs, 16 ePWM channels (150ps resolution), dual CAN, FSI, PMBus, and CLB for motor control and power conversion systems.
For engineers reviewing the F280049CPMSR datasheet, F280049CPMSR pinout, F280049CPMSR application, or F280049CPMSR equivalent, key selection criteria include functional safety compliance (ASIL B certified), InstaSPIN-FOC™ ROM support, 100-pin LQFP package compatibility, and high-resolution analog/peripheral integration for closed-loop industrial and EV charging designs.
Technical Context
The F280049CPMSR implements a dual-core real-time control architecture: the main C28x CPU executes at 100MHz with FPU, TMU, and VCU-I for fast trigonometric and complex math; the independent CLA runs parallel floating-point code at 100MHz with dedicated memory and direct peripheral access. Both cores share a unified bus architecture supporting deterministic low-latency response.
Analog subsystem includes three synchronized 12-bit ADCs (3.45MSPS, 290ns conversion time), seven PGAs (gain 3/6/12/24), seven CMPSS with 12-bit DAC references, and four SDFM input channels. Control peripherals feature 16 ePWM channels with hardware dead-band and trip zones, seven eCAP modules (two with HRCAP), and two eQEP interfaces for position sensing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F280041CPMSR | 128KB flash, no CLB, no InstaSPIN-FOC™ ROM | Limited to simpler motor control or lower-cost power supplies without advanced sensorless or logic augmentation needs | Select when flash size, CLB, or embedded FOC are not required - reduces BOM cost while retaining same 64-pin LQFP footprint and peripheral set |
| TMS320F280049CPTMR | 100-pin LQFP (PZ), 40 GPIO, 21 AIO inputs, larger package | Required for designs needing maximum analog channel count, full 16 ePWM routing, or dual eQEP with full pin access | Choose when system requires >26 GPIO, >14 AIO, or full peripheral availability - same core features but higher pin count and board area |

FAQ
What is the operating temperature range for the F280049CPMSR?
The F280049CPMSR is rated for industrial temperature operation from –40°C to 125°C junction temperature (S-grade). It does not carry AEC-Q100 automotive qualification - for automotive applications, the F280049C-Q1 variant must be selected. Thermal design must account for 100MHz CPU and CLA activity, with recommended PCB copper pour and thermal vias under the exposed pad.
Does the F280049CPMSR support InstaSPIN-FOC™ out of the box?
Yes, the F280049CPMSR includes the InstaSPIN-FOC™ motor control library pre-programmed in secure ROM. This enables immediate deployment of sensorless field-oriented control for BLDC and PMSM motors without external flash or license keys. The library is accessible via TI's MotorControl SDK and supports FAST™ estimator for real-time rotor position estimation.
How many analog input channels are accessible on the F280049CPMSR's 64-pin package?
The F280049CPMSR in the 64-pin LQFP (PM) package provides 14 analog input channels (AIO), mapped to pins A0–A10, B0–B4, and C0–C8. These connect directly to the three integrated 12-bit ADCs and support optional front-end conditioning via five integrated PGAs and seven comparator modules.
Is the F280049CPMSR pin-compatible with other F28004x family members in the same package?
Yes, the F280049CPMSR shares identical pinout and electrical characteristics with other 64-pin PM variants including F280041CPMSR and F280045PMSR. All support the same GPIO, analog, and peripheral mappings - enabling hardware reuse across performance tiers while varying flash size, CLB availability, and ROM features.
What safety certifications apply to the F280049CPMSR?
The F280049CPMSR is Functional Safety Quality-Managed (FS-QM), not ASIL B-certified. Only specific Q1-qualified variants (e.g., F280049C-Q1) carry ISO 26262 ASIL B certification by TÜV SÜD. For safety-critical automotive designs, the Q1 variant must be used; the F280049CPMSR remains suitable for industrial applications requiring robust design practices per IEC 61508 SIL 2.
