TMS320C25 Features

The on-chip memory of the TMS320C25 has been expanded to 4K 16-bit words of program ROM and 544 16-bit words of RAM that can be configured as data or data/program. The off-chip memory has also been increased to 64K 16-bit words of program and 64K 16-bit words of data.

The 'C25 is available in an OTP version, which replaces the 4K program ROM with OTP ROM for prototypes prior to ROM code release. This benefits production on medium-volume designs that need small space/power. It also makes a DSP system easy to implement.

Features of the 'C25 include:

• 80-, 100-, and 120-ns instruction cycle times
• Accepts source code from the TMS320C1x generation
• 128K-word external address reach
• Single-cycle multiply/accumulate (MAC)
• 134 general-purpose and DSP instructions
• Microprocessor features
• Multiprocessor features
• On-chip memory-mapped peripherals
• ANSI C compiler
• 68-pin PLCC and 80-pin PQFP OTP (TMS320P25) package versions
