Key Parameters

Substitute Part Grouping Explanation

Substitution of the TMS320C6747CZKB4 is determined by strict equivalence across the following critical parameters:

• Processor Architecture & Performance: Clock rate (456 MHz), fixed/floating-point capability, and on-chip RAM (448 kB) must remain identical
• Electrical Specifications: Core voltage (1.20V) and I/O voltage (3.30V) must match exactly
• Package & Mechanical Compatibility: 256-BGA (17x17) package ensures pin-for-pin compatibility
• Interface Functionality: All peripheral interfaces (EBI/EMI, Ethernet MAC, Host Interface, I2C, McASP, SPI, UART, USB) must be present
• Environmental & Compliance Requirements: Operating temperature range (0°C ~ 90°C), RoHS3 compliance, and MSL rating (3) must be maintained

The TMS320C6747DZKB4 qualifies as a direct substitute based on identical electrical, mechanical, and functional parameters. The primary distinction is product status: the substitute part is active, whereas the original part is obsolete.

Parameter Comparison
