TMS320C31 Features

The TMS320C31 is the second member of the 'C3x generation and is object-code compatible with the 'C30. The 'C31 has the same fast CPU as all other members of the 'C3x generation but offers a different mix of peripherals to achieve a unique price/performance point.

The 'C31 offers a lower cost than the 'C30 by removing the expansion bus and one of the serial ports, and replacing the 4K 32-bit words of internal ROM with a boot ROM. A low-power version of the 'C31 is available at 33 or 40 MHz at 3.3 V that significantly reduces power consumption. The 'C31 comes in a 132-pin plastic quad flat pack (PQFP) package.

The TMS320C31 features:

• 33-, 40-, 50-, and 60-ns instruction cycle times
• 16M-word external address reach
• Single-cycle multiply and accumulate operation
• Optimizing ANSI C compiler
• On-chip DMA
• Boot ROM
• 3.3-V version up to 40 MHz
• Two low-power modes
• Two 32-bit timers
• Serial port
• 64-word cache
• 132-pin PQFP package
