Product details
Overview
F280025PNQR from Texas Instruments is a C28x-based real-time microcontroller designed for high-efficiency power electronics control, featuring a 100MHz DSP core with IEEE 754 FPU, 128KB ECC-protected flash, 24KB RAM (ECC/parity), and 14 ePWM channels with 8 supporting 150ps high-resolution timing - deployed in solar inverters, EV charging power modules, and industrial motor drives.
For engineers reviewing the F280025PNQR datasheet, F280025PNQR pinout, F280025PNQR application, or F280025PNQR equivalent, this page delivers verified specifications, functional block context, package-validated pin roles, automotive-grade AEC-Q100 qualification (Q temperature grade), and direct alternative part comparisons for power-conversion system design.
Technical Context
The F280025PNQR integrates dual 3.45MSPS 12-bit ADCs with four post-processing blocks per converter and four windowed comparators (CMPSS) with integrated 12-bit DACs, tightly coupled to ePWM and eCAP peripherals for closed-loop control. Its real-time subsystem includes Trigonometric Math Unit (TMU) and VCRC acceleration for NLPID and CRC-intensive firmware tasks.
System-level timing is managed via two internal zero-pin 10MHz oscillators, PLL, dual-clock comparator (DCC), and windowed watchdog - all operating under single 3.3V supply with internal VREG, brownout reset, and dual-zone security for flash/RAM. The 80-pin LQFP package supports 43 GPIOs, 16 analog inputs, and full peripheral pin-muxing including CAN, FSI (200Mbps), PMBus, and dual LIN.
