NXP Semiconductors MPC8260AZUPJDB

Overview

MPC8260AZUPJDB from NXP Semiconductors (formerly Freescale) is a PowerQUICC™ II integrated communications processor featuring a dual-issue EC603e core operating up to 300 MHz, a dedicated 32-bit communications processor module (CPM), and integrated 60x/PCI/local bus interfaces. It supports 10/100-Mbit Ethernet via MII, ATM over UTOPIA, HDLC at T3 rates, and up to eight TDM channels - deployed in carrier-grade DSLAMs, enterprise routers, and telecom access gateways.

For engineers reviewing the MPC8260AZUPJDB datasheet, MPC8260AZUPJDB pinout, MPC8260AZUPJDB application, or MPC8260AZUPJDB equivalent, key selection criteria include its 480-pin TBGA package, dual PLL architecture enabling independent G2 core and CPM clocking, 32-Kbyte dual-port RAM for CPM–core data exchange, IEEE 1149.1 JTAG debug support, and compliance with PCI Specification Rev. 2.2 (MPC8265/8266 variants).

Technical Context

The MPC8260AZUPJDB implements a split-architecture design: a high-performance PowerPC G2 integer core with 16-Kbyte I/D caches and MMU coexists with a RISC-based CPM handling protocol offload for serial, TDM, and packetized traffic. Its memory controller supports glueless interfacing to SDRAM, SRAM, Flash, and EPROM across 12 programmable banks.

AC timing is defined for 66 MHz and 83 MHz system clocks with 50-pF load; DC operation requires VDD = 1.7–2.24 V (core), VCCSYN = 1.7–2.24 V (PLL), and VDDH = 3.135–3.465 V (I/O). Thermal resistance θJA is 83 °C/W on a four-layer board with natural convection.

FAQ

What is the maximum operating frequency of the MPC8260AZUPJDB core?

The MPC8260AZUPJDB features an EC603e-based G2 core rated for operation up to 300 MHz. This maximum frequency is achievable under specified conditions: VDD = 1.9–2.24 V, ambient temperature ≤ 70 °C, and proper thermal management ensuring junction temperature does not exceed 105 °C. The actual sustained frequency depends on voltage scaling, cooling, and bus loading - for example, at 200 MHz operation, VDD may be reduced to 1.7–1.92 V to lower power dissipation. MPC8260AZUPJDB supports internal clock multipliers (up to 6:1) to derive core frequency from lower-speed CLKIN inputs.

Does the MPC8260AZUPJDB include a PCI interface?

No, the MPC8260AZUPJDB does not integrate a PCI bridge. The PCI interface is exclusive to the MPC8265 and MPC8266 variants within the MPC826xA family. MPC8260AZUPJDB retains full compatibility with the 60x and local buses, supporting high-speed interconnect to external PCI controllers or bridges via its 64-bit 60x bus. Engineers designing systems requiring native PCI must select MPC8265ZUPJDB or MPC8266ZUPJDB instead. MPC8260AZUPJDB remains ideal for applications prioritizing CPM offload and TDM integration over PCI expansion.

What package type and pin count does the MPC8260AZUPJDB use?

The MPC8260AZUPJDB is packaged in a 480-ball thin ball grid array (TBGA) with 19 mm × 19 mm body size and 1.0 mm ball pitch. This RoHS-compliant package supports fine-pitch routing and efficient thermal dissipation, with θJA = 83 °C/W on a four-layer PCB. Pin assignments follow the standardized MPC826xA pinout documented in Freescale's MPC8260AEC Rev. 2.0 datasheet - including dedicated banks for 60x bus, local bus, CPM I/O (PA–PD), JTAG, and power/ground. MPC8260AZUPJDB shares identical mechanical and thermal characteristics with other 480-TBGA MPC826xA variants.

How does the CPM in the MPC8260AZUPJDB handle ATM traffic?

The MPC8260AZUPJDB's CPM supports ATM via its Fast Communications Controllers (FCCs) and optional Transfer Convergence (TC) layer - though the TC layer is only present on MPC8264 and MPC8266 variants, not MPC8260AZUPJDB. For ATM, MPC8260AZUPJDB relies on FCC2 in UTOPIA Level 2 mode to interface with external SAR chips, handling cell delineation, HEC calculation, and rate adaptation in firmware. It does not perform hardware ATM TC-layer functions like payload scrambling or idle-cell insertion - those require MPC8264ZUPJDB or MPC8266ZUPJDB. MPC8260AZUPJDB remains fully capable of ATM endpoint applications when paired with compliant external PHY/SAR devices.

What debug interfaces are supported by the MPC8260AZUPJDB?

The MPC8260AZUPJDB provides IEEE Std. 1149.1-compliant JTAG (TCK/TMS/TDI/TDO) for boundary-scan testing, flash programming, and real-time debugging, plus a Common On-Chip Processor (COP) test interface for low-level silicon validation. It also integrates a hardware watchdog timer, periodic interrupt timer, and real-time clock register accessible via the SIU - enabling robust system monitoring and recovery. These interfaces are fully operational across all voltage and temperature ranges specified in the MPC8260AEC datasheet. MPC8260AZUPJDB does not support Nexus or SWD; JTAG remains the primary debug and test vector for this device.
