NXP Semiconductors MPC8313CVRAFFB

Overview

MPC8313CVRAFFB from NXP Semiconductors (formerly Freescale) is a PowerQUICC II Pro embedded communications processor featuring an e300c3 Power Architecture core operating 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), 32-bit PCI interface (66 MHz), USB 2.0 dual-role controller with on-chip PHY, and integrated security acceleration (SEC 2.2). It serves as a main CPU or I/O processor in industrial controllers, network access servers, and intelligent NICs.

For engineers reviewing the MPC8313CVRAFFB datasheet, MPC8313CVRAFFB pinout, MPC8313CVRAFFB application, or MPC8313CVRAFFB equivalent, key selection criteria include its dual GbE MAC capability, DDR2-333 memory interface timing, PCI host/agent mode flexibility, USB OTG support via ULPI or on-chip PHY, and hardware-accelerated cryptographic offload for IPsec and IEEE 802.11i protocols.

Technical Context

The MPC8313CVRAFFB integrates an e300c3 core with 16 KB instruction and 16 KB data caches, FPU, and two integer units. Its dual enhanced three-speed Ethernet controllers (eTSECs) implement IEEE 802.3/802.3u/802.3ab compliance, TCP/IP acceleration, VLAN/PPPoE/MPLS header recognition, and IEEE 1588 timestamping - all with independent RGMII/SGMII/MII/RMII interface configuration.

It features a unified DDR1/DDR2 SDRAM controller supporting 16-/32-bit buses at up to 333 MHz, two physical banks, auto-refresh, and CKE-based power management. The security engine (SEC 2.2) provides dedicated hardware acceleration for DES, 3DES, AES, SHA-1, SHA-256, and HMAC algorithms - though the MPC8313 (non-E) variant excludes this block per official documentation.

Key Specifications

Pinout & Package

The MPC8313CVRAFFB is housed in a 620-pin, 27 mm × 27 mm, 1.0 mm pitch PBGA package (RoHS-compliant, lead-free). Pin assignments follow the standard MPC8313E footprint defined in Section 19 of the MPC8313EEC Rev. 4 datasheet, with dedicated banks for DDR, PCI, eTSEC, USB, and local bus interfaces.

FAQ

Does the MPC8313CVRAFFB include the security engine (SEC 2.2)?

No, the MPC8313CVRAFFB does not include the security engine. According to the official MPC8313EEC Rev. 4 datasheet, the security engine is present only in the MPC8313E variant - the base MPC8313 (including MPC8313CVRAFFB) omits this block. This distinction is explicitly noted in Figure 1's block diagram footnote: "Note: The MPC8313 does not include a security engine." Therefore, cryptographic acceleration for AES, SHA, or DES must be implemented in software or via external co-processors when using MPC8313CVRAFFB.

What is the maximum DDR2 data rate supported by the MPC8313CVRAFFB?

The MPC8313CVRAFFB supports DDR2 SDRAM at up to 333 MHz clock frequency, corresponding to 666 MT/s effective data rate. This is confirmed in Section 1.4 of the MPC8313EEC Rev. 4 datasheet, which states the DDR1/DDR2 memory controller supports "up to 333 MHz" and specifies GVDD = 1.8 V ± 80 mV for DDR2 operation. The controller handles 16- or 32-bit interfaces, two physical banks, and up to 16 simultaneous open pages - all validated at this speed.

Is the MPC8313CVRAFFB pin-compatible with the MPC8313EVRAGFB?

Yes, the MPC8313CVRAFFB is pin-compatible with the MPC8313EVRAGFB. Both share the identical 620-pin PBGA package (27 mm × 27 mm, 1.0 mm pitch) and identical pin mapping per Section 19 of the MPC8313EEC Rev. 4 datasheet. The only differences are temperature rating (0°C to +105°C vs. –40°C to +105°C) and minor electrical tolerances - making MPC8313EVRAGFB a drop-in replacement for extended-temperature deployments without PCB changes.

What USB modes does the MPC8313CVRAFFB support, and what external components are required?

The MPC8313CVRAFFB supports USB 2.0 dual-role (host/device/OTG) operation. It includes an on-chip full-speed/high-speed PHY, enabling standalone USB device or host functionality without external transceivers in basic configurations. For ULPI-based designs, an external ULPI PHY (e.g., SMSC USB3317) is required. The controller supports high-speed (480 Mbps), full-speed (12 Mbps), and low-speed (1.5 Mbps, host mode only) - all compliant with USB Specification Rev. 2.0.

What are the power sequencing requirements for reliable startup of the MPC8313CVRAFFB?

The MPC8313CVRAFFB requires core voltage (VDD = 1.0 V) to be applied before I/O voltages (GVDD, NVDD, LVDDA/LVDDB). Specifically, VDD must reach 90% of nominal value before any I/O supply exceeds 0.7 V. PORESET must remain asserted until at least 32 SYS_CLK_IN or PCI_SYNC_IN cycles after all supplies stabilize. Failure to follow this sequence risks I/O contention and excessive current draw. These requirements are detailed in Section 2.2 ("Power Sequencing") of the MPC8313EEC Rev. 4 datasheet.
