Product details
Overview
F280037PTRQ1 from Texas Instruments is an AEC-Q100 qualified real-time microcontroller featuring a 120-MHz C28x DSP core with IEEE 754 FPU, 256KB ECC-protected flash, 69KB ECC-protected RAM, and dual CAN/CAN FD interfaces. 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 inverter modules, on-board chargers, and industrial servo drives.
For engineers reviewing the F280037PTRQ1 datasheet, F280037PTRQ1 pinout, F280037PTRQ1 application, or F280037PTRQ1 equivalent, key selection criteria include ASIL B functional safety certification, 48-pin LQFP (PT) package compatibility, 125°C ambient temperature rating, and support for GaN/SiC gate drive timing precision in high-frequency power conversion.
Technical Context
The F280037PTRQ1 implements a dual-core real-time architecture: the main C28x CPU executes deterministic control loops at 120 MHz with FPU, TMU, and VCRC acceleration, while the independent CLA runs floating-point math tasks concurrently. Its analog subsystem tightly couples three 12-bit ADCs (4 MSPS, 250 ns conversion time) and four CMPSS modules with integrated 12-bit DAC references to enable fast overcurrent protection in motor drives.
Control peripherals include 16 ePWM channels with hardware dead-band insertion and trip-zone logic, two eQEP modules supporting CW/CCW position decoding, and eight SDFM input channels for isolated current sensing. The device supports live firmware update (LFU) with banked flash erase optimization and includes HIC for external host memory access - critical for diagnostic logging in automotive powertrain ECUs.
