Overview

MPC8560VT833LB from Freescale Semiconductor is a PowerQUICC III integrated communications processor featuring an e500 core operating at 833 MHz, 256 KB L2 cache/SRAM configurable as cache or SRAM, dual 10/100/1000 Mbps Ethernet controllers (TSEC), 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 such as carrier-grade routers and wireless baseband units.

For engineers reviewing the MPC8560VT833LB datasheet, MPC8560VT833LB pinout, MPC8560VT833LB application, or MPC8560VT833LB equivalent, key selection considerations include its 783-pin FC-PBGA package, 1.2 V core supply with 3.3 V/2.5 V I/O domains, support for IEEE 802.3z/ab/ac/gigabit Ethernet PHY interfaces (GMII/TBI/RGMII), and hardware-accelerated communication peripherals including FCCs, SCCs, and CPM.

Technical Context

The MPC8560VT833LB 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 coherency module enables cache consistency between e500 core and L2 resources via Core Complex Bus (CCB).

System-level integration includes OCeaN four-port crossbar switch fabric for packet reordering and starvation avoidance, integrated DMA controller with scatter-gather and misaligned transfer support, and programmable interrupt controller compliant with OpenPIC architecture supporting 16 priority levels and 12 discrete external interrupts.

FAQ

What is the core architecture and clock speed of the MPC8560VT833LB?

The MPC8560VT833LB features a Book E–enhanced 32-bit e500 core operating at 833 MHz. It includes 32 KB L1 instruction cache and 32 KB L1 data cache with parity protection, a memory management unit optimized for embedded real-time OS use, and performance monitor facilities. The core frequency is fixed at 833 MHz for this speed grade, requiring a 1.2 V ±60 mV VDD supply and validated under Dhrystone 2.1 benchmark conditions.

Does the MPC8560VT833LB support DDR2 or DDR3 memory?

No, the MPC8560VT833LB supports only DDR-1 SDRAM. Its DDR memory controller provides a 64-bit data interface with programmable timing for DDR-1 devices operating up to 333 MHz data rate, supporting up to four banks of memory with capacities up to 1 Gbyte per bank. DDR2 and DDR3 interfaces are not implemented in this device; later NXP QorIQ processors (e.g., P1022) introduced DDR3 support.

What Ethernet physical layer interfaces does the MPC8560VT833LB support?

The MPC8560VT833LB integrates two three-speed Ethernet controllers (TSECs) supporting IEEE 802.3z/ab/gigabit standards. It supports GMII, MII, TBI, RGMII, and RTBI physical layer interfaces. Voltage selection on LVDD pins determines compatibility: 2.5 V LVDD enables RGMII/RTBI/GMII/TBI operation, while 3.3 V LVDD supports MII and legacy 10/100 PHYs. Each TSEC includes 2-Kbyte FIFOs, RMON statistics, and 9.6-Kbyte jumbo frame capability.

Is the MPC8560VT833LB pin-compatible with other PowerQUICC III processors like the MPC8548?

No, the MPC8560VT833LB is not pin-compatible with the MPC8548 or other PowerQUICC III variants. Although both belong to the same family, they differ in pin count (783 vs. 783 for MPC8548 but with distinct ball map), I/O voltage assignments (e.g., MPC8548 adds SEC-related pins), and peripheral signal allocation. The MPC8560VT833LB's 783-ball FC-PBGA has unique pinout defined in Section 14 of its Hardware Specifications document; migration requires PCB redesign.

What is the power sequencing requirement for the MPC8560VT833LB?

The MPC8560VT833LB requires strict power sequencing: VDD and AVDD must be applied first and reach 90% of target before GVDD, LVDD, and OVDD are ramped. Violating this sequence may cause I/O contention or latch-up. Core supply is 1.2 V ±60 mV; I/O domains require 2.5 V (GVDD), 2.5/3.3 V (LVDD), and 3.3 V (OVDD). Total typical power dissipation at 833 MHz is 7.4 W (core) plus interface-specific I/O power (e.g., 0.73 W for DDR at 333 MHz).
