Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPC8323VRADDC with the MPC8323VRADDCA is based on strict equivalence across all critical electrical and mechanical parameters. The substitute relationship is determined by the following key parameters:

Core Architecture & Performance: Both parts utilize the identical PowerPC e300c2 core with 1 core, 32-bit bus width, and 266MHz clock speed, ensuring functional compatibility at the processor level.

Memory & Co-Processing: Both feature DDR and DDR2 RAM controllers with identical Communications and QUICC Engine co-processor configurations, maintaining system-level memory and signal processing capabilities.

I/O & Connectivity: Both provide 3x 10/100Mbps Ethernet ports, 1x USB 2.0 port, and identical serial interfaces (DUART, I2C, PCI, SPI, TDM, UART), ensuring peripheral compatibility.

Electrical Specifications: Both support identical I/O voltage levels (1.8V, 2.5V, 3.3V) and operating temperature range (0°C ~ 105°C), guaranteeing electrical interchangeability.

Package & Mounting: Both use 516-PBGA (27x27) package with surface mount technology, confirming mechanical and PCB-level compatibility.

Compliance & Environmental: Both are ROHS3 compliant with MSL 3 (168 Hours) rating and REACH unaffected status, meeting regulatory requirements.

The only difference is product status (obsolete vs. active) and packaging format (unspecified vs. tray), with the substitute offering active availability and tray packaging for production environments.
