NXP Semiconductors MPC8260AVVPJDB

Overview

MPC8260AVVPJDB from NXP (formerly Freescale) is a PowerQUICC™ II integrated communications processor featuring a dual-issue EC603e core running up to 300 MHz, 16 KB instruction and 16 KB data caches, and a dedicated 32-bit RISC communications processor module (CPM) with 32 KB dual-port RAM. It integrates FCCs for 10/100-Mbit Ethernet via MII, SCCs for HDLC/UART/SDLC, SMCs for BRI/GCI, SPI/I²C interfaces, eight TDM ports, and supports ATM IMA via TC-layer hardware. It targets telecom edge routers and carrier-grade access gateways.

For engineers reviewing the MPC8260AVVPJDB datasheet, MPC8260AVVPJDB pinout, MPC8260AVVPJDB application, or MPC8260AVVPJDB equivalent, key selection considerations include its 480-pin TBGA package, 1.7–2.2 V core supply range, 3.135–3.465 V I/O supply, support for 66 MHz PCI bridge (MPC8265/8266 only), and CPM-based offload of protocol processing from the G2 core - critical for deterministic real-time packet handling in embedded networking systems.

Technical Context

The MPC8260AVVPJDB implements a split-architecture design: the G2 core handles general-purpose control and routing stack execution, while the CPM executes time-critical serial protocol processing (Ethernet, HDLC, ATM, TDM) independently using microcode and dedicated DMA channels. Its dual PLL architecture allows independent clocking - e.g., 266 MHz core with 133 MHz CPM - enabling power/performance tuning without compromising real-time channel throughput.

It features a 64-bit 60x bus (up to 83 MHz), 32-bit local bus (up to 83 MHz), and a twelve-bank memory controller supporting SRAM, SDRAM, Flash, and EPROM with ECC/parity. The CPM includes three FCCs (FCC1–FCC3), four SCCs, two SMCs, SPI, I²C, eight baud rate generators, and hardware TC-layer support for ATM cell delineation, HEC generation/correction, and IMA sub-rate adaptation - all confirmed for the MPC826xA family including MPC8260A variants.

Key Specifications

Pinout & Package

Package: 480-pin Thin Ball Grid Array (TBGA), 27 mm × 27 mm, 1.27 mm ball pitch, JEDEC MO-215 compliant. Thermal pad on underside requires solder paste stencil opening and ≥6 thermal vias to internal ground plane.

Equivalent & Alternatives

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

Compared with MPC8272VRVVB and MPC8360EVVAJDB, the MPC8260AVVPJDB delivers superior CPM-based protocol offload for legacy telecom interfaces (TDM, HDLC, ATM IMA) at lower power and cost, while lacking PCI integration and modern security engines - making it ideal for established carrier access equipment where long-term availability and deterministic real-time behavior are prioritized over raw bandwidth.

FAQ

What is the maximum operating frequency of the MPC8260AVVPJDB core?

The MPC8260AVVPJDB supports a maximum G2 core frequency of 300 MHz, validated under recommended operating conditions (VDD = 1.9–2.2 V, TA = 0–70°C). At 300 MHz, it achieves 1.90 Dhrystone MIPS/MHz and 7.65 SPEC95 benchmark score. Core frequency is set via internal PLL multipliers (1.5:1 to 6:1) driven by the CLKIN reference clock.

Does the MPC8260AVVPJDB include an integrated PCI bridge?

No, the MPC8260AVVPJDB does not include an integrated 60x-to-PCI bridge. Per the MPC8260A Hardware Specifications (Rev. 2.0), PCI bridge functionality is exclusive to the MPC8265 and MPC8266 variants. The MPC8260AVVPJDB relies on external PCI interface solutions if host expansion is required.

What package type and thermal characteristics apply to the MPC8260AVVPJDB?

The MPC8260AVVPJDB uses a 480-pin TBGA package (27 mm × 27 mm, 1.27 mm pitch) with θJA = 83 °C/W (4-layer board, 1 m/s airflow) and θJB = 4 °C/W. It requires a thermal pad connected to internal ground plane via ≥6 vias and strict adherence to decoupling guidelines (four 0.1 µF capacitors near package corners) to maintain junction temperature ≤105°C.

How many TDM interfaces does the MPC8260AVVPJDB support, and what protocols are covered?

The MPC8260AVVPJDB supports up to eight TDM interfaces, with hardware routing to SI RAM and TC-layer blocks. It natively handles T1/E1, T3/E3, ISDN basic/primary rate, PCM highway, Freescale IDL, and GCI protocols. Each TDM channel supports bit- or byte-resolution framing and independent transmit/receive routing with programmable frame sync.

Is the MPC8260AVVPJDB pin-compatible with other MPC826xA family members like MPC8272 or MPC8360?

No, the MPC8260AVVPJDB is not pin-compatible with MPC8272VRVVB (516-pin PBGA) or MPC8360EVVAJDB (620-pin PBGA). Pin counts, package dimensions, ball pitch, and I/O assignments differ significantly across these families. Migration requires PCB redesign and firmware adaptation due to architectural changes (e.g., CPM vs. QUICC Engine).
