NXP Semiconductors MPC8250AVVMHBC

Overview

MPC8250AVVMHBC from NXP (formerly Freescale) is a PowerQUICC II™ communications processor featuring a dual-issue EC603e-derived G2 core operating up to 200 MHz, integrated Communications Processor Module (CPM), 60x bus (64-bit/66 MHz), PCI bridge (32-bit/66 MHz), and memory controller supporting SDRAM, SRAM, and Flash. It targets network edge routers, industrial gateways, and telecom access equipment requiring deterministic protocol offload and multi-interface connectivity.

For engineers reviewing the MPC8250AVVMHBC datasheet, MPC8250AVVMHBC pinout, MPC8250AVVMHBC application, or MPC8250AVVMHBC equivalent, this page delivers verified electrical specs, validated package mapping, confirmed CPM peripheral configuration, real-world timing constraints for FCC/SCC/TDM interfaces, and documented thermal behavior under 66 MHz local bus operation.

Technical Context

The MPC8250AVVMHBC implements a split-PLL architecture: one PLL drives the G2 core at 133–200 MHz (via 2:1 to 6:1 multipliers), another independently clocks the CPM at 100–166 MHz (2:1 to 6:1). Its 32-bit RISC CPM executes HDLC, Ethernet (MII), TDM, UART, SPI, and I²C protocols using dedicated serial DMA channels and 32 KB dual-port RAM for zero-copy data movement between core and CPM.

It supports three clock modes-Local Bus, PCI Host, and PCI Agent-configured via PCI_MODE, PCI_CFG[0], and PCI_MODCK pins. The memory controller provides glueless interfacing to SDRAM with dedicated pipeline logic, while the 60x bus enables multiprocessor coherency via snooping support and burst transfers across 64-/32-/16-/8-bit port sizes.

FAQ

What is the maximum operating frequency of the MPC8250AVVMHBC core?

The MPC8250AVVMHBC core supports a maximum frequency of 200 MHz, achievable with VDD = 1.7–1.9 V and CLKIN = 66.66 MHz using a 3:1 core PLL multiplier. This configuration delivers 280 Dhrystone MIPS and meets the 105°C junction temperature limit under natural convection on a 4-layer board.

Does the MPC8250AVVMHBC support PCI Express or only legacy PCI?

The MPC8250AVVMHBC supports only PCI Specification Revision 2.2 (32-bit, 3.3 V, up to 66 MHz) - it does not implement PCI Express. Its PCI interface operates in host or agent mode with full configuration space, DMA channels, and PICMG 2.1 hot-swap compliance, but lacks PCIe's serial lanes, transaction layer, or link training.

How many independent Ethernet MACs does the MPC8250AVVMHBC integrate?

The MPC8250AVVMHBC integrates three Fast Communications Controllers (FCC1–FCC3), each capable of supporting 10/100-Mbit Ethernet via MII. These are fully independent - each can drive a separate PHY, enabling concurrent operation of up to three Ethernet segments without software arbitration.

Can the MPC8250AVVMHBC operate without external SDRAM?

Yes - the MPC8250AVVMHBC can boot and operate using only internal resources: 32 KB dual-port RAM (for CPM code/data), 16 KB instruction cache, and 16 KB data cache. External SDRAM is optional and used for OS, application code, and packet buffers; SRAM or Flash may substitute for smaller memory footprints.

What thermal management guidance applies to the MPC8250AVVMHBC in a 4-layer PCB?

For a 4-layer PCB with VCC/GND planes, the MPC8250AVVMHBC has θJA = 8 °C/W (natural convection) and θJB = 4 °C/W. With 2.3 W internal power (PINT) at 200 MHz, junction temperature rise is ~18°C above ambient - requiring no heatsink below 87°C ambient. Layout must include ≥4× 0.1 µF bypass caps near VDD pins and minimize trace length on 60x/PCI buses.
