TMS320C203 Features

The 'C203 features the core CPU of the 'C20x generation and several peripherals that optimize it for low-cost, high-volume applications.

The 'C203 has one synchronous serial port with a 4-deep FIFO,which results in less intervention from the CPU, at a low cost.There is also one full-duplex asynchronous serial port (UART), a 16-bit timer, and a software wait-state generator.The serial ports, timer, and wait-state generator are each mapped into I/Ospace.


Features of the TMS320C203 include:

  • 25-, 35-, and 50-ns instruction cycle times
  • 192K-word external address reach
  • Accepts source code from the TMS320C1x/'C2x generations
  • ANSI C compiler
  • 2, ´1, ´2,and ´4 PLL options
  • IEEE 1149.1-standard (JTAG) emulator control
  • Available Boot loader
  • Full-duplex synchronous serial port with 4-level-deep FIFO
  • Full-duplex asynchronous serial port (UART)
  • 100-pin TQFP package
