TMS320C32 Features

The TMS320C32 is the lowest-cost 32-bit floating-point device TI offers. The 'C32 is object-code compatible with the 'C30 and 'C31.

The 'C32 has a flexible memory interface that allows access to 8-, 16-, or 32-bit memory. This can lead to considerable savings in system cost.

There are also two low-power modes on the 'C32. One reduces the clock rate of the device but continues execution, while the other suspends instruction execution and puts the device on hold. These are valuable features in power-critical applications.

The 'C32 features the same boot ROM as the 'C31, has two 256-word ´ 32-bit blocks of on-chip RAM, and comes in a 144-pin PQFP.

Features of the TMS320C32 include:

  • 33-, 40-, and 50-ns instruction cycle times
  • Object-code compatible with the 'C30/'C31
  • 16M-word external address reach
  • Flexible memory interface (8, 16, or 32 bits)
  • Two-channel DMA with configurable priorities
  • Low-power modes
  • 64-word program cache
  • Two 32-bit timers
  • 144-pin PQFP or TQFP package
