NXP Semiconductors MPC8313CVRAFFC

Overview

MPC8313CVRAFFC from NXP Semiconductors (formerly Freescale) is a PowerQUICC II Pro communications processor featuring the 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), 32-bit PCI interface (66 MHz), USB 2.0 dual-role controller with on-chip PHY, and integrated DMA, I²C, SPI, DUART, and GPIO. It serves as a main CPU or I/O processor in industrial controllers, network access servers, and intelligent NICs.

For engineers reviewing the MPC8313CVRAFFC datasheet, MPC8313CVRAFFC pinout, MPC8313CVRAFFC application, or MPC8313CVRAFFC equivalent, key selection considerations include its 333 MHz e300c3 core performance, dual GbE MACs with IEEE 1588 support, DDR1/DDR2 memory interface voltage flexibility (1.8 V / 2.5 V), PCI 2.3 compliance, and USB 2.0 host/device capability - all in a 620-pin PBGA package rated for industrial temperature range (–40°C to +105°C).

Technical Context

The MPC8313CVRAFFC integrates an e300c3 core with 16 KB instruction and 16 KB data caches, FPU, and two integer units. Its memory subsystem supports one 16-/32-bit DDR1/DDR2 interface with up to 333 MHz clocking, two physical banks, and auto-refresh. The security engine (SEC 2.2) is omitted in the MPC8313 variant per documentation - unlike the MPC8313E - confirming this part lacks hardware acceleration for DES, AES, SHA-1, or MD-5.

Its dual enhanced three-speed Ethernet controllers (eTSECs) implement full TCP/IP offload including IPv4/IPv6 header recognition, checksum generation/verification, VLAN tagging, and eight transmit/receive queues. The USB 2.0 controller supports OTG via external ULPI PHY or operates with its on-chip full-speed/high-speed PHY, while the 32-bit PCI interface complies with revision 2.3 and supports both host and agent modes with 3.3-V signaling only.

FAQ

Does MPC8313CVRAFFC include a hardware security engine?

No, MPC8313CVRAFFC does not include a security engine. Documentation explicitly states "The MPC8313 does not include a security engine," distinguishing it from the MPC8313E variant. Cryptographic operations must be handled in software or via external accelerators. This omission reduces power consumption and cost while maintaining identical pinout and peripheral functionality for non-encrypted applications.

What is the maximum DDR2 data rate supported by MPC8313CVRAFFC?

MPC8313CVRAFFC supports DDR2 SDRAM at up to 333 MHz clock frequency, corresponding to 666 MT/s data rate. This is confirmed in Section 1.4 of the hardware specifications, which states "Support for up to 333 MHz" and lists 333 MHz, 32-bit operation with 1.8 V GVDD in Table 2. The controller supports x8/x16/x32 devices up to 4-Gbit density with auto-refresh and on-the-fly CKE power management.

Is MPC8313CVRAFFC pin-compatible with MPC8313EVRADDC?

Yes, MPC8313CVRAFFC is pin-compatible with MPC8313EVRADDC. Both are 620-pin PBGA packages with identical mechanical dimensions, ball pitch, and signal assignment per the "Package and Pin Listings" section (Section 19) of the MPC8313E datasheet. The only functional difference is the absence of the SEC 2.2 engine in MPC8313CVRAFFC - all I/O, memory, and peripheral pins map identically.

What power supply sequencing is required for reliable MPC8313CVRAFFC startup?

MPC8313CVRAFFC requires core voltage (VDD = 1.0 V) to be applied before I/O supplies (GVDD, NVDD, LVDDA). Per Section 2.2, VDD must reach 90% of nominal value before any I/O rail exceeds 0.7 V, and PORESET must remain asserted for ≥32 SYS_CLK_IN or PCI_SYNC_IN cycles after stable clocks and power are established. Failure to follow this sequence risks I/O contention and excessive current draw.

Which Ethernet PHY interfaces does MPC8313CVRAFFC support natively?

MPC8313CVRAFFC natively supports RGMII, SGMII, MII, RMII, and RTBI interfaces through its dual eTSECs. Section 1.7 confirms "Two RGMII/SGMII/MII/RMII/RTBI interfaces" and notes "On-chip high-speed serial interface to external SGMII PHY interface." No external PHY is needed for SGMII links; RGMII and MII require external PHYs with compatible voltage levels (2.5 V or 3.3 V).
