TMS320C53S Features

There are slight differences between the 'C53 and the 'C53S. In order to accommodate the integration capabilities of the 'C53 into a 100-pin TQFP package, some features were removed from the standard 'C53. Some of the features of the 'C53 are not available. The 'C53S offers two standard serial ports instead of the TDM and standard serial ports in the 'C53. The 'C53S has reduced capability of the on-chip analysis block and has no boundary scan.

Features included on the TMS320C53S are:

• 25-, 35-, and 50-ns instruction cycle times
• 192K-word external address reach
• Accepts source code from the 'C1x/'C2x/'C2xx generations
• ANSI C compiler
• IEEE 1149.1-standard (JTAG) emulator control
• Boot ROM option
• Full-duplex synchronous serial port
• 100-pin TQFP package
