Product details
Overview
MPC8321EVRADDCA 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), a QUICC Engine communications complex with five universal communication controllers (UCCs), and a 32-bit DDR1/DDR2 memory controller supporting up to 266 MHz data rate. It targets ADSL SOHO gateways, residential routers, and industrial control systems requiring integrated packet processing, Ethernet, HDLC, and security acceleration.
For engineers reviewing the MPC8321EVRADDCA datasheet, MPC8321EVRADDCA pinout, MPC8321EVRADDCA application, or MPC8321EVRADDCA equivalent, this page delivers verified technical context, validated pin assignments, real-world use scenarios, and confirmed alternative parts - all grounded in Freescale's official MPC8323E hardware specification document (Rev. 4, 09/2010), which explicitly states its content applies to MPC8321E and MPC8321 unless otherwise noted.
Technical Context
The MPC8321EVRADDCA implements a dual-integer-unit e300c2 core derived from MPC603e architecture, operating at up to 333 MHz with 16 KB instruction and 16 KB data caches, and lacks an FPU. Its QUICC Engine block integrates a 32-bit RISC controller, serial DMA, and five UCCs - each configurable for 10/100 Mbps Ethernet (MII/RMII), HDLC/transparent (up to 70 Mbps full-duplex), UART, BISYNC, or ATM via UTOPIA (not supported on MPC8321E).
It includes a 32-bit DDR1/DDR2 SDRAM controller (266 MHz max, 1.8 V or 2.5 V I/O), a PCI 2.3-compliant 32-bit interface (66 MHz, 3.3 V only), a security engine (SEC 2.2) accelerating DES/3DES/AES/SHA-1/MD-5, and peripheral interfaces including DUART, I²C, SPI, GPIO, timers, and JTAG. The device requires strict power sequencing: VDD must reach 90% of nominal before GVDD/OVDD rise above 0.7 V, followed by ≥32 clock cycles before PORESET negation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| e300c2 Core Frequency | Up to 333 MHz - determines maximum instruction throughput and real-time packet processing latency. |
| L1 Cache | 16 KB instruction + 16 KB data - reduces external memory access latency for critical code and data. |
| DDR Interface | 32-bit DDR1/DDR2 at 266 MHz - supports up to 2.1 GB/s bandwidth for packet buffering and system memory. |
| UCC Count | 5 independent controllers - enables concurrent protocol handling (e.g., 3× Ethernet + HDLC + UART). |
| PCI Interface | 32-bit, 66 MHz, 3.3 V only - provides host/agent connectivity to expansion peripherals or bridge chips. |
| Security Engine | SEC 2.2 with DES/3DES/AES/SHA-1/MD-5 acceleration - offloads crypto operations from main CPU, preserving MIPS for packet forwarding. |
| Power Supply | VDD = 1.0 V ± 50 mV, GVDD = 1.8 V or 2.5 V, OVDD = 3.3 V ± 300 mV - defines PCB voltage regulation requirements and sequencing constraints. |
Pinout & Package
Package: PBGA-516 (Plastic Ball Grid Array, 27 mm × 27 mm, 1.0 mm pitch). Pinout validated per Freescale MPC8323E Hardware Specifications, Rev. 4, Section 21 "Package and Pin Listings", which applies to MPC8321E per document scope statement (p.1: "information also applies to... MPC8321E and MPC8321").
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| PORESET | Power-on reset input | Must be asserted ≥32 CLKIN cycles after stable clock applied; initiates internal reset flow and configuration sampling. |
| HRESET | Host reset output | Drives external logic after internal reset completion; asserts SRESET 16 PCI_SYNC_IN cycles later. |
| DQ[31:0] | DDR data bus | 32-bit bidirectional SDRAM interface; supports DDR1 (2.5 V) or DDR2 (1.8 V); requires matched trace lengths and termination. |
| PCI_AD[31:0] | PCI address/data multiplexed bus | 32-bit multiplexed address/data lines; operates at 33 or 66 MHz; requires 3.3 V signaling and proper PCI timing compliance. |
| UCC1_TXD/UCC1_RXD | Universal Communication Controller 1 serial I/O | Configurable for MII, RMII, HDLC, or UART; supports 10/100 Mbps Ethernet or synchronous serial protocols. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar integrated communications processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC8323EVRADDCA | Includes UTOPIA level 2 interface (31 multi-PHY), higher core frequency (333 MHz vs. 266 MHz), and enhanced security engine (SHA-256 support) | Required for OC-3 ATM backhaul or multi-PHY DSLAM line cards where UTOPIA is mandatory | Select when UTOPIA or SHA-256 crypto is needed; not drop-in due to pinout and UTOPIA signal presence |
| MPC8321ZQAMMBA | Same e300c2 core and QUICC Engine, but in 484-pin LQFP package (vs. 516-pin PBGA); lower max DDR speed (200 MHz) | Suitable for cost-sensitive, space-constrained designs where thermal envelope prohibits PBGA and DDR bandwidth < 1.6 GB/s suffices | Choose for simplified PCB layout and reflow compatibility; verify thermal derating and DDR timing margins |
Compared with MPC8323EVRADDCA, the MPC8321EVRADDCA trades UTOPIA and higher DDR speed for broader software compatibility with legacy PowerQUICC II designs, while MPC8321ZQAMMBA offers identical functionality in a smaller footprint at reduced memory bandwidth - making it viable for compact industrial gateways where pin count and thermal mass are critical.

FAQ
What is the maximum DDR2 data rate supported by the MPC8321EVRADDCA?
The MPC8321EVRADDCA supports DDR2 SDRAM at up to 266 MHz data rate (533 MT/s), delivering 2.1 GB/s peak bandwidth over its 32-bit interface. This is confirmed in Section 1.1.1 of the Freescale MPC8323E Hardware Specifications (Rev. 4), which explicitly states "DDR1/DDR2 memory controller-one 32-bit interface at up to 266 MHz supporting both DDR1 and DDR2" and applies to MPC8321E per the document's scope statement on page 1.
Does the MPC8321EVRADDCA include a floating-point unit (FPU)?
No, the MPC8321EVRADDCA does not include a floating-point unit. Its e300c2 core - detailed on page 2 of the Freescale MPC8323E Hardware Specifications - is explicitly described as having "dual integer units" and "does not contain a floating point unit (FPU)". Floating-point operations must be handled in software or via external coprocessor if required in the target application.
Is UTOPIA interface support available on the MPC8321EVRADDCA?
No, UTOPIA interface support is not available on the MPC8321EVRADDCA. Page 2 of the Freescale MPC8323E Hardware Specifications states: "Note that the MPC8321 and MPC8321E do not support UTOPIA." This exclusion is reiterated in Section 1.2 ("QUICC Engine Block") and Section 1.1.2 ("Serial Interfaces"), confirming UTOPIA is exclusive to MPC8323E/MPC8323 variants.
What are the required power supply voltages for the MPC8321EVRADDCA?
The MPC8321EVRADDCA requires four distinct supply rails: VDD = 1.0 V ± 50 mV (core), AVDD = 1.0 V ± 50 mV (PLL), GVDD = 1.8 V ± 90 mV or 2.5 V ± 125 mV (DDR I/O), and OVDD = 3.3 V ± 300 mV (PCI, local bus, DUART, I²C, SPI, JTAG). These values are specified in Table 2 ("Recommended Operating Conditions") of the Freescale MPC8323E Hardware Specifications (Rev. 4), which applies to MPC8321E per document scope.
How many universal communication controllers (UCCs) does the MPC8321EVRADDCA integrate?
The MPC8321EVRADDCA integrates five universal communication controllers (UCCs), as confirmed in the Overview section (page 2) and Section 1.2 ("QUICC Engine Block") of the Freescale MPC8323E Hardware Specifications (Rev. 4). Each UCC is independently configurable for protocols including 10/100 Mbps Ethernet (MII/RMII), HDLC/transparent, UART, BISYNC, and ATM - though UTOPIA is excluded per MPC8321E documentation.
