Product details
Overview
TMS320F280049PMSR from Texas Instruments is a 100MHz C28x 32-bit real-time microcontroller with IEEE 754 FPU, CLA accelerator, 256KB flash, 100KB RAM, and integrated analog (3×12-bit ADCs, 7 PGAs, 7 CMPSS). It targets high-precision motor control and power conversion systems requiring deterministic timing, sensorless FOC via InstaSPIN-FOC™, and functional safety support.
For engineers reviewing the TMS320F280049PMSR datasheet, TMS320F280049PMSR pinout, TMS320F280049PMSR application, or TMS320F280049PMSR equivalent, key selection criteria include CLA co-processing capability, 150ps ePWM resolution, ASIL B functional safety certification, and 64-pin LQFP package compatibility for space-constrained industrial inverters and EV charging modules.
Technical Context
The TMS320F280049PMSR integrates a dual-core real-time control architecture: a 100MHz C28x CPU with TMU/VCU-I for fast trigonometric and complex math, plus an independent 100MHz CLA executing floating-point control loops in parallel. Its analog subsystem includes three synchronized 3.45MSPS ADCs with four post-processing blocks each and seven windowed comparators with 12-bit DAC references.
Control peripherals feature 16 ePWM channels with 150ps high-resolution capability, integrated dead-band generation, hardware trip zones, and two eQEP modules supporting CW/CCW operation. Communications include two CAN ports, two SPI, two SCI, one I²C, one LIN, one PMBus, and one FSI interface - all pin-bootable and muxed across 40 GPIOs.
