NXP Semiconductors MPC8313ECZQAFFC

Overview

MPC8313ECZQAFFC from NXP Semiconductors (formerly Freescale) is a PowerQUICC II Pro communications processor featuring the e300c3 Power Architecture core running at up to 333 MHz, dual 10/100/1000 Mbps Ethernet controllers with RGMII/SGMII/MII support, DDR1/DDR2 memory controller (16-/32-bit, up to 333 MHz), integrated USB 2.0 dual-role controller with on-chip PHY, and 32-bit PCI interface operating at up to 66 MHz - deployed as main CPU or I/O processor in industrial controllers, network access servers, and intelligent NICs.

For engineers reviewing the MPC8313ECZQAFFC datasheet, MPC8313ECZQAFFC pinout, MPC8313ECZQAFFC application, or MPC8313ECZQAFFC equivalent, key selection considerations include its 333 MHz e300c3 core performance, dual eTSEC timing and TCP/IP acceleration capabilities, DDR2-333 memory interface voltage tolerance (1.8 V ± 80 mV), and PCI 2.3 compliance at 3.3 V - all critical for embedded networking and control system design.

Technical Context

The MPC8313ECZQAFFC integrates an e300c3 core with 16 KB instruction and 16 KB data caches, FPU, and two integer units, coupled with a dedicated security engine (SEC 2.2) supporting DES, 3DES, AES, SHA-1, and MD-5 offload. Its clocking architecture uses a programmable PLL with lock time ≤100 µs and supports SYS_CLK_IN or PCI_SYNC_IN inputs (24–66.67 MHz).

It implements dual enhanced three-speed Ethernet controllers (eTSECs) compliant with IEEE 802.3/802.3u/802.3ab/1588, each with 10-KB TX and 2-KB RX FIFOs, VLAN/PPPoE/MPLS header recognition, and per-packet configurable acceleration. The DDR1/DDR2 controller supports up to two physical banks, 16–32-bit bus width, and auto-refresh with CKE-based power management.

FAQ

What is the maximum DDR2 data rate supported by the MPC8313ECZQAFFC?

The MPC8313ECZQAFFC DDR2 interface supports up to 333 MHz clock frequency, corresponding to DDR2-667 data rates (333 MT/s). This is confirmed in Section 1.4 of the hardware specifications, which states "support for up to 333 MHz" and lists GVDD = 1.8 V ± 80 mV as the recommended operating condition for DDR2 operation at that speed. The controller supports 16- or 32-bit bus widths and two physical banks.

Does the MPC8313ECZQAFFC include a hardware security engine?

Yes, the MPC8313ECZQAFFC includes the SEC 2.2 security engine, as explicitly stated in Section 1.3 and Figure 1 of the hardware specifications. It accelerates DES, 3DES, AES, SHA-1, and MD-5 algorithms and is optimized for IPSec, 802.11i, and iSCSI. Note that the base MPC8313 (without 'E') does not include this engine, but the MPC8313ECZQAFFC - being an MPC8313E variant - does.

What are the power supply sequencing requirements for the MPC8313ECZQAFFC?

The MPC8313ECZQAFFC requires core voltage (VDD/VDDC = 1.0 V) to reach 90% of nominal value before any I/O supply (GVDD, LVDD, NVDD) exceeds 0.7 V. PORESET must be asserted until at least 32 SYS_CLK_IN or PCI_SYNC_IN cycles after both core and I/O supplies stabilize. This sequence is defined in Section 2.2 and prevents I/O contention and excessive current draw during power-up.

Which Ethernet PHY interfaces are supported by the MPC8313ECZQAFFC eTSECs?

The MPC8313ECZQAFFC dual eTSECs support RGMII, SGMII, MII, RMII, and RTBI interfaces, as specified in Section 1.7. Each eTSEC can be independently configured for any of these modes via configuration registers and strap pins. SGMII enables direct connection to serial PHYs without external clock forwarding, while RGMII supports standard 1 Gbps PHYs with reduced pin count.

Is the MPC8313ECZQAFFC pin-compatible with other PowerQUICC II Pro processors?

No, the MPC8313ECZQAFFC is not pin-compatible with other PowerQUICC II Pro processors such as the MPC8315E or MPC8377E. While it shares the 620-pin PBGA package with some variants, pin assignments for DDR, PCI, and eTSEC signals differ across the family. The hardware specifications confirm unique pin listings for MPC8313E in Section 19 and do not declare cross-family pin compatibility.
