Product details
Overview
TMS320F280049CRSHSR from Texas Instruments is a 100MHz C28x 32-bit floating-point real-time MCU with CLA, TMU, VCU-I, 256KB flash, 100KB RAM, three 3.45MSPS 12-bit ADCs, 16 ePWM channels (150ps resolution), and dual CAN interfaces - designed for high-precision motor control in EV charging power modules and solar string inverters.
For engineers reviewing the TMS320F280049CRSHSR datasheet, TMS320F280049CRSHSR pinout, TMS320F280049CRSHSR application, or TMS320F280049CRSHSR equivalent, key selection criteria include functional safety compliance (ASIL B), integrated InstaSPIN-FOC™ ROM library, CLA offloading capability, 56-pin RSH package constraints, and analog front-end configuration (7 PGAs, 7 CMPSS, 2 DACs).
Technical Context
The TMS320F280049CRSHSR implements a dual-core real-time control architecture: the main C28x CPU runs at 100MHz with IEEE 754 FPU, TMU, and VCU-I for fast trigonometric and complex math; the independent CLA also operates at 100MHz with floating-point support and direct peripheral access - enabling parallel execution of critical control loops without CPU intervention.
Its analog subsystem integrates three synchronized 12-bit ADCs (3.45MSPS, 290ns conversion time), seven programmable gain amplifiers (gain settings: 3/6/12/24), seven windowed comparators with 12-bit DAC references, and two buffered DAC outputs - all coordinated via four post-processing blocks per ADC for real-time signal conditioning in closed-loop power conversion.
Key Specifications
