TMS320C6748EZWT3

Overview

The TMS320C6748EZWT3 is a fixed- and floating-point digital signal processor based on the C674x VLIW architecture, housed in a 361-ball NFBGA package with a 16.00 mm x 16.00 mm body size. It operates at clock frequencies of up to 375 MHz (at 1.2V core voltage) or 456 MHz (at 1.3V). The device delivers performance up to 3648 MIPS and 2746 MFLOPS. Internal memory includes 32KB L1P cache, 32KB L1D cache, 256KB L2 unified RAM/cache, and 128KB shared RAM. I/O voltages are configurable for 1.8V or 3.3V LVCMOS.

Feature Summary

• C674x DSP Core: Supports up to 3648 MIPS and 2746 MFLOPS with IEEE single/double precision floating-point capabilities.
• Memory Architecture: Features a two-level cache system (32KB L1P, 32KB L1D, 256KB L2) and 128KB shared RAM accessible by other hosts.
• Peripheral Set: Includes EMAC, SATA, USB 2.0 OTG, USB 1.1 OHCI, PRUSS subsystem, and multiple serial interfaces (UART, SPI, I2C, McBSP).
• EDMA3 Controller: Provides 64 independent DMA channels and 16 quick DMA channels for high-efficiency data transfer.

Applications

• Currency Inspection
• Biometric Identification
• Low-End Machine Vision

Procurement Notes

Verify the specific suffix 'EZWT3' against the manufacturer's current ordering guide to confirm package dimensions and temperature range. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Ensure the source document matches the exact part number to avoid discrepancies in pinout or electrical specifications.

Selection Notes

Select this component when a low-power mixed-signal processor with robust connectivity is required. The choice between 375 MHz and 456 MHz operation depends on the available core supply voltage (1.2V vs 1.3V). Ensure the design accommodates the 16mm x 16mm NFBGA footprint and manages thermal dissipation for the ZWT package variant.

Part Context

This device belongs to the TMS320C6000 platform, specifically the C674x family. It integrates a C674x DSP core with an ARM926EJ-S core in some variants, though the C6748 datasheet focuses on the DSP subsystem. It is designed for applications requiring high computational throughput with low power consumption compared to previous generations.

Replacement Considerations

Check for code compatibility with other C6000 series devices such as the TMS320C6747 or TMS320C6745. Verify peripheral availability and memory map differences before substitution. Consult the device comparison section in the official datasheet for detailed hardware feature distinctions.
