TMS320C40GFL40

Digital Signal Processor Dsp Overview

The TMS320C40GFL40 is a 32-bit floating-point digital signal processor from Texas Instruments, operating at a 50 MHz clock speed with a 50-ns instruction cycle time. It delivers 330 MOPS and 60 MFLOPS performance. The device features six on-chip communication ports for direct interprocessor connectivity without external glue logic, a six-channel DMA coprocessor, and an IEEE 1149.1 (JTAG) boundary scan interface. Internal memory includes 8 KB of dual-access RAM and a 512-byte instruction cache. It utilizes a 325-pin Ceramic Grid Array (GF) package and operates on a single 5-V supply.

Digital Signal Processor Dsp Feature Summary

• Six on-chip communication ports enabling direct processor-to-processor communication with automatic arbitration and handshaking.
• Single-cycle conversion to/from IEEE-754 floating-point format with 40-bit floating-point and 32-bit integer multipliers.
• Six-channel Direct Memory Access (DMA) coprocessor supporting split-mode operation for doubled channel availability during I/O transfers.
• On-chip program cache (512 bytes) and dual-access RAM (8 KB) to maximize sustained CPU performance.

Digital Signal Processor Dsp Applications

• Parallel image processing systems for non-contact inspection in medical and industrial applications.
• Speech recognition systems utilizing feature extraction and Hidden Markov Models for embedded applications.
• Real-time video restoration and processing using multiple DSP configurations.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'GFL40' against the manufacturer's datasheet to confirm the 50 MHz speed grade ('C40-50') and GF package type. Confirm silicon revision details if software reset or NMI bus-grant features are required, as these depend on revision 5.0 or higher. Check RoHS compliance status for current manufacturing standards.

Digital Signal Processor Dsp Selection Notes

Select this component for high-performance parallel processing tasks requiring low-latency interprocessor communication. Ensure the system design accommodates the 325-pin BGA footprint and 5-V power requirements. Consider the C3x assembly language compatibility if migrating legacy code. Verify that the application benefits from the specific 50 MHz throughput rather than requiring the faster 60 MHz variant.

Digital Signal Processor Dsp Part Context

The TMS320C40 belongs to the fourth generation of Texas Instruments DSPs, designed primarily for parallel processing. It is source-code compatible with the TMS320C3x family. The GFL40 designation indicates the GF ceramic grid array package and the 50 MHz operational speed grade within the C40 series.

Digital Signal Processor Dsp Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The TMS320C44 is a related member of the C4x family but differs in pin count and specifications; verify functional equivalence before substitution.
