Product details
Overview
F280034PTRQ1 from Texas Instruments is an AEC-Q100 qualified real-time microcontroller featuring a 120-MHz C28x DSP core with IEEE 754 FPU, 128KB flash (ECC-protected), 69KB RAM (ECC-protected), and dual CAN interfaces (DCAN + MCAN). It integrates 16 ePWM channels (8 with 150-ps resolution), three 4-MSPS 12-bit ADCs, and CLA for parallel control-law execution - deployed in automotive EV charging station power modules and industrial servo drive position feedback.
For engineers reviewing the F280034PTRQ1 datasheet, F280034PTRQ1 pinout, F280034PTRQ1 application, or F280034PTRQ1 equivalent, key selection criteria include its 48-pin LQFP (PT) package, -40°C to 125°C operating range, functional safety support up to ASIL B/SIL 2, and compatibility with TI's C2000™ real-time control ecosystem including C2000Ware and TMDSCNCD280039C evaluation hardware.
Technical Context
The F280034PTRQ1 implements a deterministic real-time control architecture centered on a 120-MHz C28x CPU with FPU, TMU, and VCRC extensions - enabling fast execution of motor control algorithms like NLPID and trigonometric functions. Its CLA operates at 120 MHz independently, executing floating-point math without CPU intervention and accessing peripherals directly via dedicated message RAM.
Hardware acceleration includes 8 SDFM input channels (two parallel filters per channel), four windowed comparators (CMPSS) with integrated 12-bit DAC references, and Fast Serial Interface (FSI) supporting up to 200 Mbps isolated communication. The device supports Live Firmware Update with bank-parallel flash erase and context switching for minimal downtime during field updates.

FAQ
What is the maximum operating temperature for the F280034PTRQ1?
The F280034PTRQ1 is rated for a free-air operating temperature range of –40°C to 125°C and a junction temperature range of –40°C to 150°C. These limits are validated per AEC-Q100 stress testing and apply to all functional modes including full CPU, CLA, and peripheral operation under worst-case voltage and load conditions. Thermal derating is not required within this envelope when PCB layout follows TI's recommended copper pour and thermal pad guidelines.
Does the F280034PTRQ1 support CAN FD communication?
Yes, the F280034PTRQ1 includes one Controller Area Network with Flexible Data-Rate (CAN FD/MCAN) port compliant with ISO 11898-1:2015. It supports data rates up to 5 Mbps, payloads up to 64 bytes, and CRC-17 error detection - enabling high-bandwidth diagnostics and firmware updates in automotive EV charging and HVAC systems. This is distinct from its separate legacy DCAN port.
How much flash memory does the F280034PTRQ1 have, and is it ECC-protected?
The F280034PTRQ1 contains 128KB (64KW) of on-chip flash memory, organized into two independent 64KB banks. All flash is protected by Error-Correcting Code (ECC) circuitry that detects and corrects single-bit errors and detects double-bit errors - essential for functional safety compliance and long-term reliability in automotive and industrial deployments.
Can the F280034PTRQ1 execute control algorithms independently of the main CPU?
Yes, the F280034PTRQ1 integrates a Control Law Accelerator (CLA) that operates at 120 MHz and executes floating-point code independently of the C28x CPU. The CLA has dedicated program/data RAM, direct peripheral access, and hardware task switching - allowing real-time execution of PID, NLPID, or FOC loops while the CPU handles communications, diagnostics, or user interface tasks.
What development tools are supported for the F280034PTRQ1?
The F280034PTRQ1 is fully supported by TI's C2000™ software ecosystem, including C2000Ware SDK, ControlSuite libraries, and CCS IDE with CLA-aware debugging. Hardware evaluation is enabled by the TMDSCNCD280039C controlCARD, which shares pin-compatible headers and can be adapted for F280034PTRQ1 via configuration files and jumper settings - no PCB redesign required.
