Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPC8347EVRADDB is based on the following critical parameters that must remain consistent:

• Core Architecture: PowerPC e300 processor family
• Package Format: 620-HBGA (29x29) with 620-BBGA Exposed Pad configuration
• Clock Speed: 266MHz operation
• Bus Width: 32-Bit single core
• Mounting Technology: Surface Mount BGA
• Operating Temperature Range: 0°C ~ 105°C
• I/O Voltage Compatibility: Minimum support for 2.5V and 3.3V levels
• Regulatory Compliance: ROHS3 and REACH requirements

The MPC8343VRADDB qualifies as a substitute based on matching these core electrical and mechanical parameters while maintaining the same package footprint and thermal specifications.

Parameter Comparison

Engineering Selection Recommendations

The MPC8343VRADDB is a direct substitute for the obsolete MPC8347EVRADDB based on matching core processor architecture, clock frequency, package geometry, and thermal operating range. Both devices maintain ROHS3 compliance and identical MSL ratings, ensuring equivalent handling and storage requirements.

The MPC8343VRADDB offers enhanced capabilities including support for DDR2 memory controllers in addition to DDR, an additional Gigabit Ethernet port, and extended I/O voltage support down to 1.8V. These enhancements provide functional compatibility while enabling broader system integration options.

The transition from the obsolete MPC8347EVRADDB to the active MPC8343VRADDB ensures continued component availability and manufacturing support for new production runs and field replacements.

Frequently Asked Questions (FAQ)
