NXP Semiconductors MPC8313ECZQAGDC

Overview

MPC8313ECZQAGDC from NXP Semiconductors (formerly Freescale) is a PowerQUICC II Pro communications processor featuring an e300c3 Power Architecture core running at 333 MHz, dual 10/100/1000 Mbps Ethernet controllers with RGMII/SGMII/MII support, DDR1/DDR2 memory controller (up to 333 MHz), integrated security engine (SEC 2.2), and USB 2.0 dual-role controller with on-chip PHY - deployed in industrial controllers, network access servers, and intelligent NICs.

For engineers reviewing the MPC8313ECZQAGDC datasheet, MPC8313ECZQAGDC pinout, MPC8313ECZQAGDC application, or MPC8313ECZQAGDC equivalent, key selection considerations include eTSEC TCP/IP offload capability, DDR2 1.8 V I/O compatibility, PCI 2.3 host/agent mode support, SEC 2.2 cryptographic acceleration (AES/SHA-1/MD5), and thermal operation up to 105°C junction temperature.

Technical Context

The MPC8313ECZQAGDC integrates an e300c3 core with 16 KB instruction and 16 KB data caches, FPU, and two integer units, coupled with a programmable interrupt controller supporting 5 external and 34 internal sources. Its DDR1/DDR2 controller supports 16-/32-bit interfaces at up to 333 MHz with auto-refresh, CKE-based power management, and 1.8 V / 2.5 V SSTL2-compatible I/O.

It implements dual enhanced three-speed Ethernet controllers (eTSECs) compliant with IEEE 802.3/802.3u/802.3ab, supporting jumbo frames (9.6 KB), VLAN stacking, IEEE 1588 timestamping, and hardware-accelerated IP/TCP/UDP checksum generation/verification. The security engine provides dedicated crypto execution units for DES/3DES, AES, and SHA-1/MD5.

FAQ

What is the maximum DDR2 memory capacity supported by the MPC8313ECZQAGDC?

The MPC8313ECZQAGDC DDR2 controller supports up to 4-Gbit devices with x8/x16/x32 data widths, enabling configurations up to 512 MB per 32-bit channel. It allows two independent chip selects, so total addressable memory can reach 1 GB using two 512-MB DDR2 modules. The controller validates 1.8 V operation and supports on-the-fly CKE power-down for dynamic power scaling during idle periods. MPC8313ECZQAGDC does not support x4 DDR2 devices.

Does the MPC8313ECZQAGDC include a hardware security engine?

Yes, the MPC8313ECZQAGDC includes the SEC 2.2 security engine with dedicated execution units for DES/3DES (DEU), AES (AESU), and SHA-1/MD5 (MDEU). It supports IPSec, IEEE 802.11i, and iSCSI offload via a single crypto-channel with multi-command descriptor chaining. This hardware acceleration reduces CPU utilization by up to 70% during encrypted packet processing. Note that the non-E variant (MPC8313) omits this engine entirely - MPC8313ECZQAGDC explicitly includes it.

What are the power sequencing requirements for reliable MPC8313ECZQAGDC startup?

MPC8313ECZQAGDC requires core voltage (VDD = 1.0 V ± 50 mV) to reach 90% of nominal before any I/O supply (GVDD, NVDD, LVDDA) exceeds 0.7 V. PORESET must remain asserted for ≥32 SYS_CLK_IN cycles after both core and I/O supplies stabilize. Violating this sequence risks bus contention and excessive current draw. The MPC8313ECZQAGDC datasheet specifies no mandatory power-down order, but recommends disabling unused block clocks first to minimize leakage. All power rails must be connected even if associated peripherals are unused.

Can the MPC8313ECZQAGDC operate in PCI agent mode with a 33 MHz clock?

Yes, the MPC8313ECZQAGDC PCI controller fully supports agent mode at 33 MHz, including PCI 2.3 compliance, 3.3 V signaling, and PME detection. In this configuration, PCI_SYNC_IN serves as the reference clock, and the device responds to memory and I/O cycles initiated by the host. The controller supports selectable coherency enforcement and on-chip arbitration for up to three external masters. MPC8313ECZQAGDC achieves full 132 MB/s bandwidth at 33 MHz, matching standard PCI specification limits.

What Ethernet PHY interfaces are supported by the MPC8313ECZQAGDC eTSECs?

The MPC8313ECZQAGDC dual eTSECs support RGMII, SGMII, MII, RMII, and RTBI interfaces - enabling direct connection to common PHYs like Marvell 88E1111 (RGMII), Broadcom BCM5461 (SGMII), or National DP83848 (MII). Each eTSEC includes an MII management interface for PHY register access and status polling. The on-chip high-speed serial interface supports SGMII PHYs without external level shifters. MPC8313ECZQAGDC does not integrate a PHY; all PHYs remain external components.
