Key Parameters

Substitute Part Grouping Explanation

Substitution of the VCBUP7TC6 is based on strict alignment of the following critical parameters:

• Series and Architecture: Both parts must belong to the TMS320DM646x DaVinci™ series to ensure functional compatibility with existing firmware and software stacks.
• Package and Pinout: Identical 529-pin FCBGA (19x19) package ensures mechanical and electrical compatibility with existing PCB layouts.
• Interface Set: Both parts must support the complete interface suite (EBI/EMI, Ethernet, HPI, I2C, McASP, PCI, SPI, UART, USB) for system integration compatibility.
• Memory Configuration: Matching ROM (8kB) and On-Chip RAM (248kB) specifications ensure software compatibility.
• Voltage Rails: Both I/O (1.8V, 3.3V) and core voltage specifications must be compatible with existing power delivery networks.
• Operating Temperature Range: 0°C ~ 85°C (TC) specification must be maintained for thermal design compatibility.
• Compliance Standards: RoHS3 compliance and MSL 4 rating must be preserved for manufacturing and supply chain requirements.
