MPC8321EVRADDC Equivalent & Substitute Parts

Part Overview

The MPC8321EVRADDC is a PowerPC e300c2 microprocessor IC from the MPC83xx series, featuring a single 32-bit core operating at 266MHz in a 516-PBGA package. This embedded processor integrates communications capabilities through a QUICC Engine, security features including SEC 2.2 cryptography, dual DDR/DDR2 RAM controllers, and multiple interface options including three 10/100Mbps Ethernet ports, USB 2.0, and serial interfaces.

The MPC8321EVRADDC is classified as obsolete. Identifying equivalent substitute parts is necessary to support legacy system maintenance, design updates, and procurement continuity when original inventory becomes unavailable.

Substitute Part Grouping Explanation

Substitute parts for the MPC8321EVRADDC are identified based on strict equivalence across the following critical parameters:

• Core processor architecture: PowerPC e300c2
• Core count and bus width: 1 Core, 32-Bit
• Operating frequency: 266MHz
• Physical package: 516-PBGA (27x27)
• RAM controller support: DDR and DDR2
• Ethernet capability: 10/100Mbps with 3 ports
• USB interface: USB 2.0 (1 port)
• I/O voltage levels: 1.8V, 2.5V, 3.3V
• Operating temperature range: 0°C ~ 105°C
• Security and communications co-processors: SEC 2.2 and QUICC Engine
• Interface set: DUART, I2C, PCI, SPI, TDM, UART

The MPC8321EVRADDCA meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The MPC8321EVRADDCA is a direct functional equivalent to the MPC8321EVRADDC. Both parts share identical electrical specifications, pin configurations, and performance characteristics across all measured parameters.

The primary distinction is product status: the MPC8321EVRADDC is obsolete, while the MPC8321EVRADDCA maintains active status. This status difference reflects manufacturing and supply availability rather than technical capability.

Both parts carry identical export control classifications (ECCN 5A002A1) and tariff codes (HTSUS 8542.31.0001), indicating equivalent regulatory treatment. Both comply with RoHS3 and REACH requirements as specified for their respective product lines.

For new designs or system updates, the MPC8321EVRADDCA is the appropriate selection due to its active product status and ongoing manufacturer support. For legacy system maintenance where the original MPC8321EVRADDC is specified, the MPC8321EVRADDCA provides drop-in compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can the MPC8321EVRADDCA be used as a direct replacement for the MPC8321EVRADDC in existing designs?

A: Yes. The MPC8321EVRADDCA is electrically and mechanically identical to the MPC8321EVRADDC. All electrical parameters, pin assignments, package dimensions, and interface specifications are equivalent. No PCB redesign or firmware modification is required.

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

A: The parts are functionally identical. The difference is product lifecycle status: MPC8321EVRADDC is obsolete, while MPC8321EVRADDCA is active. The manufacturer designation also differs (NXP USA Inc. versus Freescale Semiconductor), reflecting historical corporate transitions within the same product line.

Q: Are the package dimensions identical?

A: Yes. Both parts use the 516-PBGA (27x27) package with 516-BBGA case designation. Physical dimensions, ball pitch, and mounting requirements are identical.

Q: Do both parts support the same operating temperature range?

A: Yes. Both parts operate across 0°C to 105°C (TA). Thermal characteristics and derating curves are equivalent.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical ECCN (5A002A1) and HTSUS (8542.31.0001) classifications. Both comply with RoHS3 and REACH requirements. Moisture sensitivity level (MSL 3, 168 hours) applies to the MPC8321EVRADDC; equivalent handling requirements apply to the MPC8321EVRADDCA.

Q: Which part should be specified for new procurement?

A: The MPC8321EVRADDCA should be specified for new designs and procurement activities due to its active product status and manufacturer support. The MPC8321EVRADDC remains available for legacy system support where original specifications must be maintained.
