Product details
Overview
TMS320F280045PMSR from Texas Instruments is a 100MHz C28x-based real-time MCU with IEEE 754 FPU, CLA accelerator, 128KB flash, 100KB RAM (ECC/parity-protected), and integrated analog subsystem including three 3.45MSPS 12-bit ADCs - deployed in solar string inverters and EV on-board chargers for high-precision motor control.
For engineers reviewing the TMS320F280045PMSR datasheet, TMS320F280045PMSR pinout, TMS320F280045PMSR application, or TMS320F280045PMSR equivalent, key selection criteria include CLA offload capability, 16-channel ePWM with 150ps resolution, dual CAN interfaces, functional safety quality management (FS-QM), and 64-pin LQFP package compatibility with industrial temperature range (–40°C to 125°C).
Technical Context
The TMS320F280045PMSR implements a dual-core real-time control architecture: the main C28x CPU executes at 100MHz with FPU, TMU, and VCU-I for fast trigonometric and complex math, while the independent CLA runs parallel floating-point code for time-critical loop tasks. Both cores share access to dual-bank flash and ECC-protected RAM.
Analog integration includes three synchronized 12-bit ADCs (3.45MSPS), seven PGAs (gain 3/6/12/24), seven windowed comparators with 12-bit DAC references, two buffered DAC outputs, and four SDFM input channels - enabling closed-loop sensing across isolated power stages without external signal conditioning.
