Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TMS320C6747BZKB4 is determined by strict alignment across the following critical parameters:

Core Electrical Specifications: Clock rate (456MHz), processor type (fixed/floating-point), core voltage (1.20V), and I/O voltage (3.30V) must remain identical to ensure functional compatibility within existing circuit designs.

Memory Architecture: On-chip RAM capacity (448kB) and non-volatile memory configuration (external) must match to preserve software compatibility and system performance characteristics.

Physical & Thermal Requirements: Package type (256-BGA), supplier device package dimensions (17x17), and operating temperature range (0°C ~ 90°C) must be equivalent to ensure mechanical fit and thermal performance in the target application.

Compliance & Certification: RoHS3 compliance, MSL rating (3), and REACH status must align to meet regulatory and manufacturing process requirements.

Interface Specification: All peripheral interfaces (EBI/EMI, Ethernet MAC, Host Interface, I2C, McASP, SPI, UART, USB) must be present and functionally identical.

Parameter Comparison

Engineering Selection Recommendations

The TMS320C6747DZKB4 is a direct functional equivalent to the TMS320C6747BZKB4. All electrical, thermal, mechanical, and interface specifications are identical. The primary distinction is product status: the TMS320C6747DZKB4 maintains Active status with current manufacturing support, while the TMS320C6747BZKB4 is Obsolete.

For new designs or system refreshes, the TMS320C6747DZKB4 is the appropriate selection. Both parts carry identical RoHS3 compliance and REACH status, ensuring regulatory alignment. The TMS320C6747DZKB4 is available in Tray packaging, whereas the original part was supplied in standard packaging.

Frequently Asked Questions (FAQ)

Q: Can the TMS320C6747DZKB4 be used as a direct replacement for the TMS320C6747BZKB4?

A: Yes. All functional, electrical, thermal, and mechanical parameters are identical. The substitute part is pin-compatible and functionally equivalent for all applications designed for the original part.

Q: What is the difference between these two part numbers?
