Texas Instruments F280023PMQR

Overview

F280023PMQR from Texas Instruments is a C28x-based real-time microcontroller designed for high-efficiency power electronics control, featuring a 100MHz 32-bit DSP core with IEEE 754 FPU, 64KB ECC-protected flash, 24KB RAM (ECC/parity), and 30 GPIO pins in a 64-pin LQFP package. It supports motor control, solar inverters, and EV charging power modules.

For engineers reviewing the F280023PMQR datasheet, F280023PMQR pinout, F280023PMQR application, or F280023PMQR equivalent, key selection criteria include its 14-channel ePWM with 8 high-resolution (150ps) outputs, dual 3.45MSPS 12-bit ADCs, integrated CLB logic, CAN/PMBus/FSI interfaces, and AEC-Q100 qualification for automotive-grade reliability.

Technical Context

The F280023PMQR implements a deterministic real-time control architecture centered on the C28x CPU augmented by TMU and VCRC accelerators for fast trigonometric and CRC operations. Its analog subsystem tightly couples two 12-bit ADCs with four CMPSS modules (each with 12-bit DAC references) and post-processing blocks for closed-loop feedback.

Control peripherals include 14 ePWM channels (8 with HRPWM), three eCAP modules (one with HRCAP), two eQEP units, and dual-clock comparator (DCC) for precise timing validation. The Configurable Logic Block (CLB) provides FPGA-like logic augmentation without external components.
