NXP Semiconductors MPC8560VT667LB

Overview

MPC8560VT667LB from Freescale Semiconductor is a PowerQUICC III integrated communications processor featuring an e500 core, 256 KB L2 cache/SRAM, dual 10/100/1000 Mbps Ethernet controllers (TSECs), DDR-1 SDRAM controller (64-bit, up to 333 MHz), PCI/PCI-X (64-bit, up to 133 MHz), and RapidIO (8-bit, 500 MHz data rate). It targets high-throughput networking infrastructure systems requiring deterministic real-time packet processing.

For engineers reviewing the MPC8560VT667LB datasheet, MPC8560VT667LB pinout, MPC8560VT667LB application, or MPC8560VT667LB equivalent, key selection considerations include its 667 MHz e500 core frequency, 1.2 V core supply, 783-pin FC-PBGA package, DDR-1 memory interface timing, and dual TSEC support for IEEE 802.3ab/802.3z-compliant Gigabit Ethernet.

Technical Context

The MPC8560VT667LB implements a Book E–enhanced 32-bit e500 core with 32 KB L1 instruction and 32 KB L1 data caches (parity-protected), MMU optimized for embedded networking, and performance monitor facility. Its CPM subsystem operates at up to 333 MHz and supports FCCs, SCCs, MCCs, SPI, I²C, and time-slot assigner for TDM multiplexing.

System-level integration includes OCeaN four-port crossbar switch for internal packet routing, integrated four-channel DMA controller with scatter-gather and striding, programmable interrupt controller compliant with OpenPIC architecture (16 priority levels), and boot sequencer loading configuration via I²C from serial ROM. All interfaces-including DDR, PCI/PCI-X, RapidIO, and TSEC-support hardware-enforced coherency control.

FAQ

What is the core voltage requirement for MPC8560VT667LB?

The MPC8560VT667LB requires a nominal 1.2 V ± 60 mV core supply (VDD) for operation at 667 MHz. This voltage must be applied before all I/O supplies (GVDD, LVDD, OVDD) per the strict power sequencing defined in Freescale document MPC8560EC Rev. 4.2 Section 2.1.2. Deviation beyond ±60 mV risks timing violations or functional failure. The MPC8560VT667LB datasheet specifies this as the tested and guaranteed operating condition.

Does MPC8560VT667LB support DDR2 memory?

No, the MPC8560VT667LB supports DDR-1 SDRAM only, with a maximum data rate of 333 MHz and 2.5-V SSTL2-compatible I/O. It does not support DDR2, DDR3, or LPDDR memory standards. The DDR controller lacks DDR2-specific features such as additive latency, OCD calibration, or ZQ calibration. Designers must use DDR-1 components rated for 2.5 V and conforming to JEDEC JESD21-C specifications when implementing memory with the MPC8560VT667LB.

What is the function of the OCeaN switch fabric in MPC8560VT667LB?

The OCeaN (On-Chip Ethernet and Networking) switch fabric in the MPC8560VT667LB is a four-port crossbar that routes packets between the e500 core, dual TSECs, RapidIO interface, PCI/PCI-X controller, and DDR SDRAM controller. It enables concurrent, non-blocking data movement-such as simultaneous TSEC-to-DDR packet buffering and RapidIO-to-core control messaging-while implementing priority-based reordering and starvation avoidance. This eliminates bus contention and ensures predictable latency for time-critical networking tasks in the MPC8560VT667LB.

Can MPC8560VT667LB operate in PCI agent mode?

Yes, the MPC8560VT667LB supports both PCI host and agent modes via configuration of the PCI configuration space registers. In agent mode, it functions as a PCI endpoint device-responding to configuration reads/writes, memory-mapped I/O, and DMA requests from an external PCI host. This capability allows the MPC8560VT667LB to serve as a high-performance coprocessor on a PCI bus, as documented in Section 12 of the MPC8560EC Rev. 4.2 specification. Agent mode requires proper initialization of the PCI command/status register and base address registers.

What boot sources are supported by MPC8560VT667LB?

The MPC8560VT667LB supports booting from serial ROM via its I²C interface using the integrated boot sequencer, which verifies image integrity with preamble signature and CRC. It also supports booting from local bus flash (via default chip select), DDR SDRAM, or internal ROM. Boot source selection is controlled by hardware straps (PORCFG pins) at reset. The MPC8560VT667LB does not support booting directly from PCI, RapidIO, or TSEC interfaces-those require secondary initialization after core boot completes.
