F280049CPZS

F280049CPZS Description

A potent 32-bit floating-point microcontroller unit (MCU), the F280049CPZS enables designers to combine essential control peripherals, distinctive analog, and nonvolatile memory on a single gadget.

Based on TI's 32-bit C28x CPU, which offers 100 MHz of signal processing capabilities, the real-time control subsystem. The new TMU extended instruction set, which enables quick execution of trigonometric algorithms frequently found in transforms and torque loop calculations, as well as the VCU-I extended instruction set, which lowers the latency for complex math operations frequently found in encoded applications, give the C28x CPU even more boosts.
