NXP Semiconductors MPC8321EVRAFDC

Overview

MPC8321EVRAFDC from Freescale Semiconductor is a PowerQUICC II Pro integrated communications processor featuring an e300c2 Power Architecture core (16 KB I-cache, 16 KB D-cache, dual integer units, no FPU), QUICC Engine communications complex with five UCCs, and DDR1/DDR2 memory controller supporting up to 266 MHz data rate. It delivers packet processing for residential gateways, ADSL modems, and industrial control systems.

For engineers reviewing the MPC8321EVRAFDC datasheet, MPC8321EVRAFDC pinout, MPC8321EVRAFDC application, or MPC8321EVRAFDC equivalent, key selection factors include its 32-bit PCI 2.3 interface, security engine (SEC 2.2) supporting DES/3DES/AES/SHA-1/MD5, lack of UTOPIA support (distinguishing it from MPC8323E), and 1.0 V core supply with 3.3 V/2.5 V/1.8 V I/O voltage domains.

Technical Context

The MPC8321EVRAFDC implements a fixed-function QUICC Engine block with five universal communication controllers (UCCs) supporting 10/100 Mbps Ethernet (MII/RMII), HDLC/transparent (up to 70 Mbps), UART, BISYNC, and TDM interfaces - but explicitly excludes UTOPIA, unlike MPC8323E. Its e300c2 core executes at up to 333 MHz and integrates MMUs without floating-point capability.

It features a single 32-bit DDR1/DDR2 SDRAM controller (32-bit bus, 266 MHz max), 32-bit PCI 2.3 host/agent interface (66 MHz), USB 2.0 full-/low-speed PHY, DUART, I²C, SPI, GPIO, and a security engine (SEC 2.2) with dedicated crypto execution units for DES, 3DES, AES, SHA-1, and MD5 - all operating under strict power sequencing requiring VDD ramp before GVDD/OVDD.

Key Specifications

Pinout & Package

Equivalent & Alternatives

The following parts are listed as comparable options for similar communications processor applications.

Compared with MPC8323EVRAFDC and MPC8315EVRAGD, MPC8321EVRAFDC uniquely balances UCC count, DDR1/DDR2 flexibility, and SEC 2.2 acceleration - making it optimal for mid-tier residential gateways needing IPsec but not ATM.

FAQ

Does MPC8321EVRAFDC support UTOPIA Level 2 interface?

No, MPC8321EVRAFDC does not support UTOPIA. This is explicitly stated in Freescale's MPC8323E Hardware Specifications document (Rev. 4, Section 1.2), which notes "the MPC8321 and MPC8321E do not support UTOPIA." The absence of UTOPIA pins and related QUICC Engine configuration registers confirms this limitation in MPC8321EVRAFDC.

What DDR memory types and speeds does MPC8321EVRAFDC support?

MPC8321EVRAFDC supports both DDR1 (2.5 V) and DDR2 (1.8 V) SDRAM via a unified 32-bit controller operating up to 266 MHz (533 MT/s). It supports two ×16 devices, up to 16 open pages, auto-refresh, and CKE-based power management - but excludes FCRAM, ECC, and hardware calibration features.

What is the maximum operating frequency of the e300c2 core in MPC8321EVRAFDC?

The e300c2 core in MPC8321EVRAFDC operates at up to 333 MHz, as confirmed by Freescale's electrical characteristics tables (Table 5, "MPC8323E Power Dissipation") and the device ordering information section, which lists speed grades including 333 MHz for the MPC8321E family.

Does MPC8321EVRAFDC include a floating-point unit (FPU)?

No, MPC8321EVRAFDC does not include a floating-point unit. The e300c2 core is derived from the MPC603e architecture and contains dual integer units and MMUs, but Freescale's Overview section explicitly states "The e300c2 core does not contain a floating point unit (FPU)."

What security algorithms are accelerated by the SEC 2.2 engine in MPC8321EVRAFDC?

The SEC 2.2 engine in MPC8321EVRAFDC accelerates DES, 3DES, AES, SHA-1, and MD5 cryptographic operations. This is documented in the Security Engine section (1.3) of the MPC8323E Hardware Specifications, which applies to MPC8321E per the document's scope statement: "unless otherwise noted, the information also applies to the MPC8323, MPC8323E, MPC8321E, and MPC8321."
