HARDWARE UART FOR THE TMS320C3X

The TMS320C3X does not offer a UART for asynchronous communication. On the TI Digital Signal Processor BBS there is a software UART emulator available. This will allow the TMS320C3x to perform asynchronous communication. There are some instances that a hardware UART may be necessary for a particular application. This document describes one possible solution for implementing a hardware UART. This design was originally done in an FPGA and it can be easily transferred to an ASIC. Modification to this design can be done to accommodate faster data rates or different communication protocols. Several schematics are provided.
