Product Overview
The TMS320F280049 is a Texas Instruments 32-bit real-time microcontroller for control-oriented embedded systems. Its real-time control subsystem combines a 100 MHz TMS320C28x 32-bit CPU, IEEE 754 single-precision FPU, TMU support, VCU-I complex math acceleration, and a 100 MHz Control Law Accelerator. The TMU provides 3x to 4x cycle improvement for common trigonometric functions versus software libraries, with 13-cycle Park transform latency using the TMU feature set.
Memory resources include 256 KB / 128 KW ECC-protected flash across two independent banks and 100 KB / 50 KW ECC-protected or parity-protected on-chip RAM. System features include dual-zone security, UID support, 2 x 10 MHz internal zero-pin oscillators, crystal or external clock input, a windowed watchdog timer, 6-channel DMA, and 1.2 V core with 3.3 V I/O supply design.
Package options include 100-pin LQFP, 64-pin LQFP, and 56-pin VQFN. Peripheral integration covers ADCs, CMPSS modules, buffered DAC outputs, PGAs, high-resolution ePWM, eCAP, eQEP, sigma-delta filtering, PMBus, I2C, CAN, SPI, SCI, LIN, and FSI for real-time control, power conversion, motor-control feedback, and serial communication designs.
