Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPC8321VRAFDC is determined by strict equivalence across the following critical parameters:

• Core processor architecture and instruction set (PowerPC e300c2)
• Processing speed (333MHz)
• Bus width (32-Bit)
• Co-processor and DSP capabilities (Communications; QUICC Engine)
• Memory controller support (DDR, DDR2)
• Peripheral interface count and type (Ethernet 10/100Mbps ×3, USB 2.0 ×1)
• I/O voltage levels (1.8V, 2.5V, 3.3V)
• Operating temperature range (0°C ~ 105°C)
• Package form factor (516-PBGA 27x27)
• Compliance certifications (ROHS3, MSL 3)

The MPC8321VRAFDCA is identified as a direct substitute based on complete alignment with all specified parameters. The primary distinction is product status: MPC8321VRAFDC is obsolete, while MPC8321VRAFDCA maintains active status with current manufacturing availability.
