MPC8321VRADDC

Overview

The MPC8321VRADDCA is a PowerQUICC II Pro System-on-Chip microprocessor manufactured by NXP Semiconductors. It integrates an e300c2 core operating at 266 MHz with a 32-bit data bus width. The device features a PBGA-516 package and supports DDR1/DDR2 SDRAM storage types. Operating conditions range from -40°C to +105°C, with a core voltage of 1 V and I/O voltages of 1.8 V, 2.5 V, or 3.3 V. Interfaces include Ethernet, GPIO, I2C, SPI, UART, USB, PCI, and QUICC Engine capabilities.

Feature Summary

• Integrates an e300c2 core with dual integer units for efficient parallel operation without a floating-point unit.
• Includes a QUICC Engine block supporting programmable protocol termination for networking applications.
• Features a security engine providing hardware acceleration for cryptographic algorithms such as DES, AES, and SHA.
• Supports multiple communication protocols including Ethernet, ATM via UTOPIA (MPC8323E only), HDLC, and TDM.

Applications

• ADSL SOHO and residential gateways
• Modem/routers
• Industrial control systems
• Test and measurement applications

Procurement Notes

Verify the specific suffix 'VRADDCA' against official NXP documentation to confirm temperature grade and package details. Confirm end-of-life status and obsolescence notices prior to procurement. Ensure compatibility with existing PCB layouts due to the PBGA-516 footprint. Check for moisture sensitivity levels and required reflow profiles during assembly.

Selection Notes

Select this component for cost-effective, low-power communications processing requiring high integration. Consider the absence of a floating-point unit if mathematical operations are intensive. Verify interface requirements against available controllers like PCI, USB, and QUICC Engine. Evaluate power consumption characteristics relative to system thermal constraints.

Part Context

Part of the PowerQUICC II Pro family designed for networking and industrial applications. Extends previous offerings with improved CPU performance and faster interfaces. Targets markets needing converged IP packet and ATM network support. Provides backward software compatibility with earlier PowerQUICC designs.

Replacement Considerations

Consult official NXP documentation for confirmed substitute part numbers. Verify functional equivalence regarding core architecture, interface availability, and pinout compatibility before substitution.
