Product details
Overview
F280041PZS from Texas Instruments is a 100MHz C28x-based real-time MCU with IEEE 754 FPU, CLA accelerator, 128KB flash, 100KB RAM, and integrated analog (3× 3.45MSPS ADCs, 7 PGAs, 7 CMPSS). It targets high-precision motor control in EV charging power modules and solar string inverters.
For engineers reviewing the F280041PZS datasheet, F280041PZS pinout, F280041PZS application, or F280041PZS equivalent, key selection criteria include its 100-pin LQFP package, ASIL-B functional safety readiness, InstaSPIN-FOC™ ROM support, and dual CAN + FSI communication for isolated control loops.
Technical Context
The F280041PZS implements a dual-core real-time architecture: a 100MHz C28x CPU with TMU/VCU-I for fast trigonometric and complex math, plus an independent 100MHz CLA executing floating-point control law code in parallel. Its analog subsystem integrates three synchronized 12-bit ADCs with per-channel post-processing blocks and seven PGA inputs supporting gain settings of 3/6/12/24.
Control peripherals include 16 ePWM channels with 150ps high-resolution capability, seven eCAP modules (two with HRCAP), two eQEP interfaces, and four SDFM input channels. The device supports functional safety up to ASIL B via hardware integrity features and TÜV SÜD certification documentation.
