NXP Semiconductors MPC8560VT667LC

Overview

MPC8560VT667LC 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 8-bit RapidIO interface - deployed in carrier-grade networking infrastructure, wireless baseband units, and telecom edge routers.

For engineers reviewing the MPC8560VT667LC datasheet, MPC8560VT667LC pinout, MPC8560VT667LC application, or MPC8560VT667LC equivalent, key selection criteria include its 667 MHz e500 core frequency, 1.2 V core supply, 783-pin FC-PBGA package, DDR-1 memory controller timing compliance, and dual TSEC support for IEEE 802.3z/ab/3ac Gigabit Ethernet PHY interfacing.

Technical Context

The MPC8560VT667LC 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 real-time OS environments, and performance monitor facility supporting eight 32-bit event counters. Its CPM subsystem operates at up to 333 MHz and handles serial protocols including HDLC, ATM via UTOPIA, and ISDN PRI through eight TDM interfaces.

System-level integration includes an OCeaN four-port crossbar switch for packet reordering and starvation avoidance, a four-channel DMA controller with scatter-gather and misaligned transfer support, and dual TSECs with RMON statistics, 9.6-Kbyte jumbo frame capability, and configurable CRC generation/checking - all coordinated via a coherency-enabled Core Complex Bus (CCB) running at 333 MHz.

Key Specifications

Pinout & Package

FAQ

What is the maximum DDR-1 data rate supported by the MPC8560VT667LC?

The MPC8560VT667LC supports a maximum DDR-1 data rate of 333 MHz, delivering up to 5.3 GB/s peak bandwidth on its 64-bit interface. This is confirmed in Section 4 of the MPC8560 Hardware Specifications (Rev. 4.2), which specifies programmable timing for DDR-1 SDRAM with four banks, each supporting up to 1 Gbyte. The interface is 2.5-V SSTL2 compatible and includes full ECC support on 64-bit boundaries.

Does the MPC8560VT667LC include hardware support for IEEE 1588 Precision Time Protocol?

The MPC8560VT667LC does not include dedicated IEEE 1588 hardware timestamping logic. While its dual TSECs support standard Ethernet MAC functionality and can be software-configured for PTP message handling, precise sub-microsecond timestamping requires external PHYs with 1588 support or FPGA-based offload - as confirmed by absence of "PTP", "timestamp", or "1588" in the MPC8560EC Rev. 4.2 specification document sections covering TSEC, CPM, and system timers.

What is the thermal design power (TDP) of the MPC8560VT667LC at 667 MHz operation?

At 667 MHz core frequency and 333 MHz CCB frequency, the MPC8560VT667LC has a typical VDD power dissipation of 6.4 W and a maximum of 9.2 W, excluding I/O supply power (GVDD, LVDD, OVDD) and AVDD. Total system power - including DDR, PCI, and TSEC I/O - reaches approximately 10.5 W under full load, as derived from Tables 4–6 in the Hardware Specifications (Rev. 4.2).

Can the MPC8560VT667LC boot directly from SPI flash?

No, the MPC8560VT667LC does not support direct boot from SPI flash. Its boot sequencer is explicitly designed to load configuration data from serial ROM via the I2C interface only, as stated in Section 1.1 (Boot Sequencer) of the Hardware Specifications. SPI interface support is limited to peripheral master/slave operation via the dedicated SPI controller - not boot ROM access.

Is the MPC8560VT667LC pin-compatible with other MPC8560 speed grades like MPC8560VT800C?

Yes, the MPC8560VT667LC is pin-compatible with other MPC8560 variants in the 783-ball FC-PBGA package, including MPC8560VT800C and MPC8560VT1000C. All share identical mechanical footprint, ball map, and signal assignment per Section 14 ("Package and Pin Listings") of the Hardware Specifications. Differences are limited to speed grade, thermal specifications, and internal PLL configuration - requiring no PCB redesign for migration.
