Dual-Core Delfino Microcontroller - TMS320F28377D

The TMS320F2837xD device introduces the TMU, which is an accelerator that greatly reduces the number of cycles required to perform common trigonometric functions. The TMS320F2837xD device also has a second-generation Viterbi Complex Math Unit, VCU-II, with improved acceleration on Viterbi operations, complex multiplies, and the CRC engine.

The TMS320F2837xD device supports up to 1MB of ECC-protected on-board flash memory and up to 204KB of SRAM with either ECC or parity. Two independent security zones are also available for 128-bit code protection. High-precision control peripherals such as enhanced pulse width modulators (ePWMs) with fault protection, encoders, and captures are also included.
