MPC8321CZQADDC

Overview

The MPC8321CZQADDC is a PowerQUICC II Pro microprocessor based on the e300c2 core. It features a 32-bit architecture with 16 KB L1 instruction and data caches, dual integer units, and an integrated security engine (SEC 2.2). The device includes a QUICC Engine for network processing, supporting protocols such as Ethernet, HDLC, TDM, and USB 2.0. Memory interfaces include a 32-bit DDR1/DDR2 controller operating up to 266 MHz. Peripheral connectivity comprises a 32-bit PCI interface, a 16-bit local bus, SPI, I2C, DUART, and GPIO. The component operates within a temperature range of -40°C to +105°C.

Feature Summary

• Integrated QUICC Engine block providing programmable protocol termination for networking applications
• Hardware acceleration for cryptographic algorithms including DES, AES, and SHA-1 via the Security Engine
• Dual integer units in the e300c2 core designed for efficient parallel integer operations
• Support for both DDR1 and DDR2 SDRAM memory types through a single 32-bit interface

Applications

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

Procurement Notes

Verify the specific ordering suffix against official NXP documentation to confirm package type, temperature grade, and encryption status. Confirm availability status as older MPC83xx series components may be subject to end-of-life notices. Ensure design compatibility with existing software drivers intended for the PowerQUICC II Pro family.

Selection Notes

Select this processor for designs requiring a balance of CPU performance and dedicated hardware offloading for network protocols. The e300c2 core lacks a floating-point unit; verify if integer-only processing meets application requirements. Consider the integration of the QUICC Engine for reducing host CPU load in packet processing tasks.

Part Context

This component belongs to the MPC8323E PowerQUICC II Pro Integrated Communications Processor Family. The MPC8321 variant shares the same core architecture and peripheral set but typically excludes support for the UTOPIA ATM interface found in higher-end models like the MPC8323E. It serves as a cost-effective solution for converged IP and ATM networks.

FAQ

Does the MPC8321CZQADDC support the UTOPIA interface?

No, the MPC8321 and MPC8321E variants do not support the UTOPIA interface, which is specific to the MPC8323E and MPC8323 models.

What cryptographic algorithms are supported by the Security Engine?

The SEC 2.2 engine provides hardware acceleration for DES, 3DES, AES, SHA-1, MD-5, SHA-256, and HMAC algorithms.
