Product details
Overview
MPC8275CZQMIBA from NXP Semiconductors (formerly Freescale) is a PowerQUICC II integrated communications processor featuring a dual-issue G2_LE Power Architecture core, three Fast Communication Controllers (FCCs), four Serial Communications Controllers (SCCs), and PCI bridge functionality. It operates at up to 450 MHz, integrates 16 KB instruction and 16 KB data caches, and supports 10/100-Mbps Ethernet via MII/RMII interfaces - deployed in carrier-grade access routers and TDM-based edge gateways.
For engineers reviewing the MPC8275CZQMIBA datasheet, MPC8275CZQMIBA pinout, MPC8275CZQMIBA application, or MPC8275CZQMIBA equivalent, key selection criteria include FCC/SCC channel count, UTOPIA II port availability, TDM interface support, PCI bus timing compliance, and thermal performance under 105°C junction temperature operation.
Technical Context
The MPC8275CZQMIBA implements a split-clock architecture with independent PLLs for its G2_LE core (up to 450 MHz) and Communications Processor Module (CPM), enabling power/performance optimization. Its CPM includes a 32-bit RISC microcontroller, 32 KB dual-port instruction RAM, and 32 KB dual-port data RAM for offloading protocol processing from the main core.
It supports three FCCs configured for Ethernet (MII/RMII), ATM (via UTOPIA II), HDLC, or transparent modes, and four SCCs compatible with UART, HDLC, SDLC, BISYNC, and synchronous UART protocols. The device uses a 516-pin PBGA package with lead-free ZQ solder spheres and requires separate 1.45–1.60 V core/PLL and 3.135–3.465 V I/O supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | G2_LE Power Architecture v2.02 dual-issue integer core with FPU and MMU - enables real-time deterministic packet processing and Linux OS support. |
| Maximum Core Frequency | 450 MHz - achieved using internal 8:1 core/bus clock multiplier; delivers 855 Dhrystone MIPS performance. |
| Memory Subsystem | 16 KB I-Cache + 16 KB D-Cache (4-way set associative, physically addressed); 12-bank memory controller supporting SDRAM, SRAM, Flash, and EPROM. |
| Communication Peripherals | 3 × FCCs (10/100 Ethernet/MII/RMII, ATM/UTOPIA II, HDLC), 4 × SCCs (UART/HDLC/SDLC/BISYNC), 1 × USB 2.0 full/low-speed controller, 2 × TDM interfaces. |
| Bus Interfaces | 64-bit 60x bus (up to 100 MHz), 32-bit local bus (up to 100 MHz), PCI 2.2-compliant bridge (32-bit, 66 MHz, 3.3 V). |
| Thermal Rating | Junction temperature max = 105°C; RθJA = 19°C/W (four-layer board, 1 m/s airflow) - dictates heatsink requirement for sustained 450 MHz operation. |
| Supply Voltages | VDD/VCCSYN = 1.45–1.60 V (core/PLL); VDDH = 3.135–3.465 V (I/O) - mandates dual-rail power design with tight regulation and decoupling. |
Pinout & Package
Package: 516-ball PBGA (ZQ variant), lead-free solder spheres, 27 mm × 27 mm body, 1.0 mm ball pitch. Thermal pad on underside for PCB heat transfer.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PA[0–31], PB[4–31], PC[0–31], PD[4–31] | CPM General-Purpose I/O / SCC/FCC/TDM signal multiplexing | Configurable as serial interface pins (SCC/FCC), TDM channels, or GPIO; default input state prevents DC leakage. |
| A[0–31], D[0–63], L_A[14–31], LCL_D[0–31] | 60x Bus Address/Data / Local Bus Address/Data | 64-bit 60x data path and 32-bit address; local bus supports 32-bit data, 18-bit address - enables glueless SDRAM/Flash interfacing. |
| CLKIN, PLL_VDD, PLL_GND | Master Clock Input / PLL Power Supply | Accepts external 33–100 MHz reference clock; PLL supply must ramp before or simultaneously with I/O supply to avoid latch-up. |
| PCI_AD[0–31], PCI_CBE[0–3], PCI_FRAME#, PCI_IRDY#, PCI_TRDY# | PCI Bus Signals | 32-bit multiplexed address/data bus compliant with PCI Spec 2.2; supports host/peripheral mode and DMA streaming between PCI and 60x domains. |
| PORESET#, HRESET#, SRESET# | Reset Control Inputs | Three asynchronous reset inputs with different assertion timing and scope - enable hierarchical system-level reset sequencing and debug recovery. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-PLL clocking | Independent core and CPM PLLs allow asymmetric frequency scaling (e.g., 450 MHz core + 200 MHz CPM) to minimize dynamic power while maintaining protocol throughput. |
| CPM offload engine | Embedded 32-bit RISC CP with dedicated 32 KB instruction and 32 KB data RAM handles Ethernet MAC, HDLC framing, and TDM time-slot assignment without CPU intervention. |
| UTOPIA II interface | Two UTOPIA Level 2 ports support full-duplex ATM SAR at 155 Mbps with AAL0/AAL1/AAL5, CBR/VBR/UBR/ABR traffic classes - essential for DSLAM and MSAN line cards. |
| TDM subsystem | Supports eight TDM interfaces (four per MCC), 2,048-byte SI RAM, bit/byte resolution, and independent TX/RX routing - enables ISDN PRI/BRI, T1/E1, and proprietary voice/data multiplexing. |
| PCI 2.2 bridge | On-chip bridge with four DMA channels, address remapping, and hot-swap support per PICMG 2.1 - allows direct attachment of network processors, encryption ASICs, or FPGA co-processors. |
Applications
| DSL Access Multiplexer (DSLAM) | Enterprise Edge Router |
|---|---|
Use Scenario: Aggregating ADSL2+ subscriber lines into ATM or IP backhaul over SONET/SDH.

Equivalent & Alternatives
The following parts are listed as comparable options for similar integrated communications processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC8280CZQMIBA | Includes TC layer, IMA, second MCC, and two UTOPIA II ports; identical pinout and package but higher thermal envelope (1.65 W vs. 1.6 W max). | Required for ATM inverse multiplexing (IMA) and dual-TDM aggregation in metro edge nodes - not needed for basic DSLAM or router control. | Select MPC8280CZQMIBA only if TC layer or IMA functionality is required; otherwise MPC8275CZQMIBA offers cost and power advantage. |
| MPC8272CZQMIBA | Lacks UTOPIA II ports and second TDM group; supports only four TDM interfaces and no ATM SAR acceleration - same core/CPM clocking and memory subsystem. | Suitable for serial protocol concentrators and non-ATM TDM applications (e.g., E1 muxers), but cannot replace MPC8275CZQMIBA in UTOPIA-dependent designs. | Choose MPC8272CZQMIBA for cost-sensitive TDM-only deployments where ATM offload is unnecessary. |
Compared with MPC8275CZQMIBA, MPC8280CZQMIBA adds TC/IMA capability at higher power and cost, while MPC8272CZQMIBA removes UTOPIA II and half the TDM capacity - making MPC8275CZQMIBA the optimal balance for ATM-capable access equipment requiring exactly two UTOPIA ports and eight TDM channels.

FAQ
What is the maximum operating frequency of the MPC8275CZQMIBA core?
The MPC8275CZQMIBA features a G2_LE Power Architecture core rated for up to 450 MHz, achievable using internal clock multiplication ratios up to 8:1. This frequency is validated under recommended operating conditions (VDD = 1.45–1.60 V, TA = 0–70°C, TJ ≤ 105°C) and confirmed in the MPC8280EC Rev. 2 hardware specification document.
Does the MPC8275CZQMIBA support UTOPIA II interface?
Yes, the MPC8275CZQMIBA supports two UTOPIA Level 2 ports, enabling full-duplex ATM SAR at 155 Mbps with AAL0/AAL1/AAL5 and CBR/VBR/UBR/ABR traffic classes. This capability is explicitly documented in Table 1 and Figure 1 notes of the MPC8280EC Rev. 2 specification for MPC8275VR/ZQ variants.
What package type is used for the MPC8275CZQMIBA?
The MPC8275CZQMIBA uses a 516-ball PBGA package with lead-free ZQ solder spheres (27 mm × 27 mm, 1.0 mm pitch), as defined in Table 2 of the MPC8280EC Rev. 2 specification. This package is thermally optimized with an exposed thermal pad on the underside for PCB heat conduction.
How many TDM interfaces does the MPC8275CZQMIBA support?
The MPC8275CZQMIBA supports eight TDM interfaces - four per multichannel controller (MCC), with two MCCs implemented. This is confirmed in the "Features" section (page 3, note 2) and Figure 1 notes of the MPC8280EC Rev. 2 specification, which states "MPC8275VR, MPC8275ZQ only" for the second MCC and associated TDM capability.
Is the MPC8275CZQMIBA pin-compatible with the MPC8280CZQMIBA?
Yes, the MPC8275CZQMIBA and MPC8280CZQMIBA share identical 516-ball ZQ PBGA packaging and pinout, as confirmed in Table 2 of the MPC8280EC Rev. 2 specification. However, MPC8280CZQMIBA implements additional silicon features (TC layer, IMA, second MCC) not present in MPC8275CZQMIBA.
