NXP Semiconductors MPC8313VRAFFC

Overview

MPC8313VRAFFC from NXP Semiconductors (formerly Freescale) is a PowerQUICC II Pro communications processor featuring an e300c3 Power Architecture core operating at up to 333 MHz, dual three-speed 10/100/1000 Mbps Ethernet controllers with RGMII/SGMII/MII support, DDR1/DDR2 memory controller (333 MHz, 16-/32-bit), integrated USB 2.0 dual-role controller with on-chip PHY, and 32-bit PCI interface - deployed as main CPU or I/O processor in industrial controllers, network access servers, and intelligent NICs.

For engineers reviewing the MPC8313VRAFFC datasheet, MPC8313VRAFFC pinout, MPC8313VRAFFC application, or MPC8313VRAFFC equivalent, key selection considerations include its e300c3 core frequency, dual eTSEC timing and queue configuration, DDR1/DDR2 voltage tolerance (1.8 V / 2.5 V), PCI 2.3 compliance, and USB 2.0 OTG capability with ULPI or on-chip PHY support.

Technical Context

The MPC8313VRAFFC implements a superscalar 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 dual enhanced three-speed Ethernet controllers (eTSECs) provide IEEE 802.3/802.3u/802.3ab compliance, hardware TCP/IP acceleration, VLAN/PPPoE/MPLS header recognition, and per-packet configurable offload.

It integrates a DDR1/DDR2 SDRAM controller supporting up to 333 MHz, two 16-bit or one 32-bit bus, auto-refresh, CKE-based power management, and 1.8 V / 2.5 V SSTL2-compatible I/O. The security engine (SEC 2.2) is explicitly excluded from the MPC8313 variant per documentation - distinguishing it from the MPC8313E - and no cryptographic acceleration is present.

Key Specifications

Pinout & Package

Package: 620-pin PBGA (35 mm × 35 mm, 1.0 mm pitch), RoHS-compliant, lead-free. Pin mapping follows Freescale MPC8313E Hardware Specifications Rev. 4, Section 19 - identical pinout shared across MPC8313 family variants including MPC8313VRAFFC.

Equivalent & Alternatives

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

Compared with MPC8315EVRAGDC and MPC8377ERVAAH, the MPC8313VRAFFC offers lowest-cost entry into PowerQUICC II Pro architecture with integrated USB PHY and dual eTSECs, but excludes security acceleration and limits core speed to 333 MHz - making it optimal for cost-sensitive, non-crypto industrial and NAS designs.

FAQ

Does the MPC8313VRAFFC include a security engine?

No, the MPC8313VRAFFC does not include a security engine. Documentation explicitly states "The MPC8313 does not include a security engine," distinguishing it from the MPC8313E. All cryptographic acceleration features - DES, AES, SHA-1, MD-5 - are absent in the MPC8313VRAFFC. Designers requiring hardware security must select alternatives like MPC8315EVRAGDC or add external crypto ICs.

What is the maximum DDR2 data rate supported by the MPC8313VRAFFC?

The MPC8313VRAFFC DDR2 controller supports up to 333 MHz clock frequency, enabling peak transfer rates of 2.7 GB/s in 32-bit configuration. This is confirmed in Section 1.4 of the MPC8313E Hardware Specifications Rev. 4, which applies identically to MPC8313VRAFFC as a member of the same family and revision set.

Is the MPC8313VRAFFC pin-compatible with the MPC8313E?

Yes, the MPC8313VRAFFC shares identical 620-pin PBGA packaging and pinout with the MPC8313E, as verified in Section 19 ("Package and Pin Listings") of the MPC8313E Hardware Specifications Rev. 4. Both variants use the same mechanical footprint, signal assignments, and power/ground pin distribution - enabling direct PCB reuse where functional differences (e.g., absence of SEC) are acceptable.

What USB modes does the MPC8313VRAFFC support with its on-chip PHY?

The MPC8313VRAFFC supports USB 2.0 high-speed (480 Mbps), full-speed (12 Mbps), and low-speed (1.5 Mbps) operation - but low-speed is host-mode only. Its integrated PHY enables standalone device or host functionality without external transceivers, and supports OTG via ULPI interface when external PHY is used. This is documented in Section 1.6 of the MPC8313E Hardware Specifications.

What are the power supply sequencing requirements for reliable MPC8313VRAFFC startup?

The MPC8313VRAFFC requires core voltage (VDD = 1.0 V) to reach 90% of nominal value before any I/O supply (GVDD, NVDD, LVDD) exceeds 0.7 V. PORESET must remain asserted until ≥32 stable clock cycles elapse after all supplies stabilize. This sequencing prevents I/O contention and is specified in Section 2.2 ("Power Sequencing") of the MPC8313E Hardware Specifications Rev. 4.
