Product details
Overview
F280048PMQR from Texas Instruments is a 100MHz C28x 32-bit floating-point real-time MCU with CLA, 128KB flash, 100KB RAM, three 3.45MSPS 12-bit ADCs, 16 ePWM channels (150ps resolution), and dual CAN interfaces - designed for high-precision motor control in industrial inverters and EV charging power modules.
For engineers reviewing the F280048PMQR datasheet, F280048PMQR pinout, F280048PMQR application, or F280048PMQR equivalent, this page delivers verified specifications, functional safety context (ASIL B certified), package-specific peripheral mapping, and validated alternative options for automotive-grade power conversion designs.
Technical Context
The F280048PMQR implements a dual-core real-time control architecture: a 100MHz C28x CPU with IEEE 754 FPU, TMU, and VCU-I accelerates trigonometric and complex math; a parallel 100MHz CLA offloads control-loop tasks without CPU intervention. Its analog subsystem integrates seven PGAs (gain 3/6/12/24), seven CMPSS with 12-bit DAC references, and four SDFM input channels for sigma-delta sensor interfacing.
System-level features include dual-zone security with UID, ECC-protected flash/RAM, 64-pin LQFP (PM) package with 26 GPIOs and 14 AIO inputs, and functional safety compliance up to ASIL B per TÜV SÜD certification - targeting ISO 26262-compliant motor drives and on-board chargers requiring systematic capability at SIL 3.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time motor control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F280049C-Q1 | 256KB flash, CLB enabled, InstaSPIN-FOC™ ROM, same 64-pin PM package and Q-temp rating | Required for designs needing >128KB firmware space, CLB-based position sensing, or pre-validated sensorless FOC | Select when expanding firmware complexity or adding encoderless operation without external FOC library licensing. |
| TMS320F280035PMQR | 120MHz C28x, CAN-FD support, 256KB flash, no CLB or InstaSPIN-FOC™, same 64-pin PM package | Targeted at next-gen chargers requiring higher bandwidth CAN communication and enhanced security features | Choose for new designs prioritizing CAN-FD diagnostics, AES encryption, or migration path to F28003x roadmap. |
Compared with F280048PMQR, the F280049C-Q1 adds CLB and InstaSPIN-FOC™ for advanced motion control, while the F280035PMQR trades CLB for CAN-FD and stronger security - making F280048PMQR optimal for cost-sensitive, ASIL B-compliant inverters where legacy CAN and proven FOC IP suffice.

FAQ
What is the functional safety qualification status of the F280048PMQR?
The F280048PMQR is Functional Safety Quality-Managed (FS-QM) and certified to ISO 26262 ASIL B by TÜV SÜD. It includes hardware safety mechanisms such as ECC on flash/RAM, windowed watchdog timers, and missing-clock detection - documented in TI's Functional Safety Manual SPRUHZ6. The F280048PMQR does not carry full ASIL B compliance like the F280048C-Q1 variant, but supports systematic development up to SIL 3 for IEC 61508 systems.
Does the F280048PMQR include the Configurable Logic Block (CLB)?
No, the F280048PMQR does not include the Configurable Logic Block. CLB is only available on C-suffix variants (e.g., F280048C-Q1). The F280048PMQR is a non-C variant with identical CPU, CLA, analog, and communication peripherals but excludes CLB tiles and InstaSPIN-FOC™ ROM - confirmed in TI's Device Comparison Table (SPRS945H, Section 4).
What are the key differences between F280048PMQR and F280048C-Q1?
The F280048PMQR uses the standard F280048 core with 128KB flash and no CLB or InstaSPIN-FOC™, while the F280048C-Q1 adds CLB (4 tiles), InstaSPIN-FOC™ ROM, and functional safety compliance (ASIL B). Both share the same 64-pin PM package, Q-temp rating (–40°C to 125°C), and peripheral set - but the C-Q1 variant targets safety-critical automotive applications requiring hardware-accelerated position sensing and certified motor control IP.
Which analog peripherals are accessible on the 64-pin PM package of the F280048PMQR?
The F280048PMQR in the 64-pin PM package supports 14 analog input pins (AIO0–AIO13), seven PGA inputs (PGA1_IN through PGA5_IN, PGA7_IN, plus shared grounds), two buffered DAC outputs (DACA_OUT, DACB_OUT), and seven CMPSS modules - all fully functional per TI's Signal Descriptions table (Section 5.3) and Electrical Characteristics (Section 6.10).
Can the F280048PMQR support dual CAN communication simultaneously?
Yes, the F280048PMQR integrates two independent CAN 2.0B controllers (CAN0 and CAN1) with dedicated RX/TX pins on the 64-pin PM package (pins 31/32 and 47/48). Both ports support bit rates up to 1Mbps, loopback/self-test modes, and pin-bootable initialization - enabling concurrent communication with BMS and vehicle gateway in EV charging applications.
