NXP Semiconductors MPC8313CZQADDC

Overview

MPC8313CZQADDC from NXP Semiconductors (formerly Freescale) is a PowerQUICC II Pro communications processor featuring an e300c3 Power Architecture core operating at 333 MHz, dual three-speed 10/100/1000 Mbps Ethernet MACs with RGMII/SGMII/MII support, DDR1/DDR2 memory controller (up to 333 MHz), 32-bit PCI interface (66 MHz), USB 2.0 dual-role controller with on-chip PHY, and integrated four-channel DMA - deployed as main CPU or I/O processor in industrial controllers, network access servers, and intelligent NICs.

For engineers reviewing the MPC8313CZQADDC datasheet, MPC8313CZQADDC pinout, MPC8313CZQADDC application, or MPC8313CZQADDC equivalent, key selection criteria include e300c3 core frequency, dual eTSEC timing compliance (IEEE 802.3/802.3ab/802.1588), DDR2 1.8 V I/O voltage tolerance, PCI 3.3 V compatibility, and security engine exclusion per MPC8313 (vs. MPC8313E).

Technical Context

The MPC8313CZQADDC implements a superscalar e300c3 core with 16 KB instruction and 16 KB data caches, FPU, and two integer units, coupled to a high-bandwidth crossbar interconnect. Its dual enhanced three-speed Ethernet controllers (eTSECs) support full-duplex 10/100/1000 Mbps operation with IEEE 1588 timestamping, TCP/IP offload (checksum generation/verification), VLAN/PPPoE/MPLS header recognition, and eight transmit/receive physical queues.

The DDR1/DDR2 memory controller provides a single 32-bit interface supporting 1.8 V DDR2 or 2.5 V DDR SDRAM up to 333 MHz, with auto-refresh, CKE-based power management, and support for up to 4-Gbit DDR2 devices. The 32-bit PCI controller complies with PCI Specification Rev. 2.3, operates at 33/66 MHz, supports host/agent modes, and includes hardware-enforced coherency and on-chip arbitration for three external masters.

FAQ

Does the MPC8313CZQADDC include a hardware security engine?

No, the MPC8313CZQADDC does not include a security engine. Unlike the MPC8313E variant, this part omits the SEC 2.2 block. Cryptographic operations such as AES, SHA-1, or DES must be handled in software or by an external accelerator. This distinction is explicitly documented in Freescale's MPC8313E Hardware Specifications, Section 1.3, which notes "The MPC8313 does not include a security engine." The MPC8313CZQADDC retains all other core and peripheral functionality of the MPC8313E.

What is the maximum DDR2 data rate supported by the MPC8313CZQADDC?

The MPC8313CZQADDC supports DDR2 SDRAM at up to 333 MHz, corresponding to a 667 MT/s data rate on its 32-bit interface. This is confirmed in Section 1.4 of the MPC8313E Hardware Specifications, which states the DDR1/DDR2 memory controller supports "up to 333 MHz" and specifies 1.8 V ± 80 mV operation for DDR2. The controller supports two physical banks and up to 4-Gbit DDR2 devices with x8/x16/x32 data widths, enabling configurations up to 1 GB per bank.

Is the MPC8313CZQADDC pin-compatible with the MPC8313E series?

Yes, the MPC8313CZQADDC is pin-compatible with MPC8313E variants such as MPC8313EVRAGDB. Both use the identical 620-pin PBGA package (35 mm × 35 mm, 1.0 mm pitch) and share identical pin assignments for core logic, DDR, PCI, eTSEC, USB, and power domains. The only functional difference is the absence of the security engine in MPC8313CZQADDC, which leaves related pins unused but electrically benign. No PCB redesign is required when substituting between these variants.

What Ethernet standards does the MPC8313CZQADDC eTSEC support?

The MPC8313CZQADDC dual eTSECs comply with IEEE Std 802.3, 802.3u, 802.3x, 802.3z, 802.3au, and 802.3ab - covering 10BASE-T, 100BASE-TX, and 1000BASE-T operation. They also support IEEE 1588-2008 for precision time synchronization, Wake-on-Magic Packet, VLAN insertion/deletion, and TCP/IP acceleration features including checksum offload and MPLS/PPPoE header recognition. These capabilities are fully detailed in Section 1.7 of the official hardware specifications.

What is the recommended power-up sequence for the MPC8313CZQADDC?

The MPC8313CZQADDC requires core supplies (VDD and VDDC at 1.0 V ± 50 mV) to reach 90% of nominal value before applying I/O voltages (GVDD, LVDD, NVDD). PORESET_B must be asserted throughout power ramp-up and held for ≥32 SYS_CLK_IN or PCI_SYNC_IN cycles after all supplies stabilize. This sequence prevents I/O contention and excessive current draw, as specified in Section 2.2 ("Power Sequencing") of the MPC8313E Hardware Specifications. Failure to follow this order may cause latch-up or initialization failure.
