NXP Semiconductors MPC8280ZUQLDA

Overview

MPC8280ZUQLDA from NXP (formerly Freescale) is a PowerQUICC II integrated communications processor featuring a dual-issue G2_LE core (450 MHz max), 32 KB on-chip RAM, 3 Fast Communication Controllers (FCCs), 4 Serial Communications Controllers (SCCs), and integrated PCI bridge, UTOPIA II, USB 2.0, and IMA/TC layer for ATM transport - deployed in telecom access equipment, DSLAMs, and enterprise edge routers.

For engineers reviewing the MPC8280ZUQLDA datasheet, MPC8280ZUQLDA pinout, MPC8280ZUQLDA application, or MPC8280ZUQLDA equivalent, this page delivers verified package mapping (480 TBGA, leaded), confirmed clocking architecture (dual PLLs for core/CPM), validated thermal resistance (RθJA = 16°C/W, 4-layer board), and real-world interface timing (FCC MII/RMII, SCC HDLC/Ethernet, TDM up to 8 channels).

Technical Context

The MPC8280ZUQLDA integrates a Power Architecture–compliant G2_LE core with separate 16 KB instruction and data caches, and a dedicated 32-bit RISC Communications Processor Module (CPM) with 32 KB dual-port RAM/ROM. Core and CPM operate at independent frequencies via dual PLLs - enabling optimized power/performance trade-offs in packet-processing workloads.

It supports three 10/100-Mbps Ethernet interfaces via MII/RMII, two UTOPIA II ports for ATM SAR, eight TDM interfaces (four per MCC), and inverse multiplexing for ATM (IMA) with TC layer hardware acceleration - all routed through a 64-bit 60x bus and 32-bit local bus, plus a PCI 2.2-compliant bridge operating up to 66 MHz.

Key Specifications

Pinout & Package

Equivalent & Alternatives

The following parts are listed as comparable options for similar integrated communications processor applications.

Compared with MPC8275VR, MPC8280ZUQLDA adds TC/IMA and dual UTOPIA for ATM transport; versus MPC8360EVRAGDB, it retains legacy TDM/UTOPIA support but lacks DDR and crypto - making MPC8280ZUQLDA optimal for brownfield telecom upgrades where protocol continuity is critical.

FAQ

What is the maximum supported core frequency for MPC8280ZUQLDA?

The MPC8280ZUQLDA supports a maximum core frequency of 450 MHz, achieved using the internal PLL with an 8:1 multiplication ratio applied to a 56.25 MHz CLKIN source. This frequency is validated under recommended operating conditions (VDD = 1.45–1.60 V, TA = 0–70°C) and delivers 855 Dhrystone MIPS performance per the Freescale MPC8280EC Rev. 2 specification.

Does MPC8280ZUQLDA support USB 2.0 device mode?

Yes, MPC8280ZUQLDA supports USB 2.0 full/low-speed device (peripheral) mode with four independent endpoints, CRC16/CRC5 checking, NRZI encoding, and automatic retransmission on transmit error. It does not include a USB PHY - an external transceiver such as the ISP1583 is required for physical layer compliance, as specified in Section 1.1 of the MPC8280EC document.

What package type is used by MPC8280ZUQLDA?

MPC8280ZUQLDA uses a 480-pin TBGA (leaded) package, code ZU, measuring 27 mm × 27 mm with 1.27 mm pitch. This package is distinct from the VR/ZQ 516 PBGA variants and features a thermal pad on the underside that must be soldered to a PCB ground plane to achieve the rated RθJB = 6°C/W thermal performance.

Can MPC8280ZUQLDA operate without external SDRAM?

Yes, MPC8280ZUQLDA can operate without external SDRAM by utilizing its on-chip 32 KB instruction RAM and 32 KB data RAM for boot code and real-time CPM tasks. However, full Linux or VxWorks operation requires external memory - the 12-bank memory controller supports SDRAM, SRAM, Flash, and EPROM, with page-mode pipeline support for high-bandwidth access.

What is the purpose of the TC layer in MPC8280ZUQLDA?

The Transmission Convergence (TC) layer in MPC8280ZUQLDA provides hardware acceleration for ATM cell processing, including cell delineation, HEC correction, and IMA frame assembly/disassembly across up to eight TDM links. It interfaces directly with FCC2 and the two MCCs, offloading these functions from the CPM and enabling deterministic latency for broadband access applications.
