TMS320DM6437ZWT4

Digital Signal Processor Dsp Overview

The TMS320DM6437ZWT4 is a fixed-point digital media processor from the DaVinci family, featuring a C64x+ DSP core with a maximum clock rate of 400 MHz. It operates at a core voltage of 1.2 V and supports I/O voltages of 1.8 V and 3.3 V. The device includes 32 KB of L1 program cache, 80 KB of L1 data cache, and 128 KB of L2 unified RAM/cache. It is housed in a 361-pin NFBGA package (16x16 mm) with a 0.8-mm ball pitch.

Digital Signal Processor Dsp Feature Summary

• C64x+ DSP Core: Up to 3200 MIPS performance at 400 MHz with VelociTI.2 extensions.
• Video Processing Subsystem (VPSS): Includes VPFE for capture (CCDC, Previewer, Resizer) and VPBE for output (OSD, VENC).
• Memory Architecture: Flexible L1/L2 cache configuration totaling 240 KB on-chip RAM plus 64 KB boot ROM.
• Peripherals: Features EMAC, EDMA3 (64 channels), HECC, PCI, McBSP, McASP, and up to 111 GPIOs.

Digital Signal Processor Dsp Applications

• Digital video surveillance systems
• Networked media encode/decode devices
• Video imaging applications

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade suffix '4' corresponds to the required 400 MHz operating frequency. Confirm the ZWT package designation matches the 361-pin BGA requirement. Check RoHS compliance status and moisture sensitivity level (MSL 3) for assembly planning. Ensure development tools are compatible with the C64x+ architecture.

Digital Signal Processor Dsp Selection Notes

Select this model if a 400 MHz processing speed is sufficient for the application. Compare against higher-speed variants like the -5 or -6 suffixes if greater MIPS performance is needed. Consider the ZDU package option if a 1.0-mm pitch is preferred. Verify that the 1.2 V core voltage supply capability is available in the system design.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320DM643x series within the DaVinci platform. It shares the same silicon and peripheral set as other speed grades (e.g., DM6437-5, DM6437-6) but is limited to a 400 MHz clock rate. It is designed for high-performance digital media processing tasks requiring efficient video handling.

Digital Signal Processor Dsp Replacement Considerations

Direct functional substitutes include other TMS320DM6437 variants with different speed grades (e.g., TMS320DM6437ZWT5, TMS320DM6437ZWT6) provided the lower 400 MHz limit meets system requirements. Package alternatives like the ZDU suffix offer the same functionality in a 376-pin BGA.
