TMS320C32PCM60

Digital Signal Processor Dsp Overview

The TMS320C32PCM60 is a high-performance floating-point digital signal processor from the TMS320C3x family, manufactured by Texas Instruments. It features a 32-bit CPU with a 33-ns instruction cycle time, delivering 60 MFLOPS and 30 MIPS at a 5-V supply. The device includes two 256 × 32-bit single-cycle dual-access on-chip RAM blocks, an enhanced external memory interface supporting 8-, 16-, or 32-bit widths, and peripherals such as a serial port, two timers, and a two-channel DMA coprocessor. It is housed in a 144-pin Plastic Quad Flat Package (PQFP) and operates within a commercial temperature range of 0°C to 85°C.

Digital Signal Processor Dsp Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and moisture sensitivity level (MSL 4) prior to soldering. Check for obsolescence status as this model may be discontinued. Ensure proper handling of ESD-sensitive pins during assembly.

Digital Signal Processor Dsp Selection Notes

Select the TMS320C32PCM60 when 60 MFLOPS performance is required with a 5-V logic interface. Compare against TMS320C32PCM40 (40 MHz) or TMS320C32PCM50 (50 MHz) if lower speed suffices. Consider the 144-pin package constraints and external memory interface complexity for system design.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320C3x generation of DSPs, which are object-code compatible with the earlier TMS320C30 and TMS320C31 models. The PCM suffix denotes the 144-pin plastic quad flat package variant operating at 5 V. It utilizes Texas Instruments' 0.7-mm EPIC technology.

Digital Signal Processor Dsp Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Texas Instruments for current equivalent products or migration paths from the C3x family.
