NXP Semiconductors XPC8260CVVIHBC

Overview

XPC8260CVVIHBC from Freescale Semiconductor is a PowerQUICC II integrated communications processor featuring a dual-issue EC603e-derived G2 core, a dedicated 32-bit communications processor module (CPM), and support for 10/100-Mbps Ethernet, ATM UTOPIA, HDLC, TDM, and serial protocols. It operates at up to 200 MHz core frequency with 16 KB instruction and 16 KB data caches, 24 KB dual-port RAM for CPM–core communication, and integrated memory controllers for SDRAM, SRAM, and Flash. It is used in telecom access equipment, industrial gateways, and legacy network edge routers requiring deterministic real-time protocol offload.

For engineers reviewing the XPC8260CVVIHBC datasheet, XPC8260CVVIHBC pinout, XPC8260CVVIHBC application, or XPC8260CVVIHBC equivalent, this page delivers verified electrical specs (VDD = 2.4–2.7 V, VDDH = 3.135–3.465 V), clock configuration modes (up to 200 MHz core / 166 MHz CPM), thermal resistance (θJA = 7.78 °C/W, 4-layer board), AC timing (66 MHz bus, 50 pF load), and confirmed package mapping (TBGA-516).

Technical Context

The XPC8260CVVIHBC integrates a PowerPC G2 core and an independent RISC-based CPM sharing 24 KB on-chip dual-port RAM, enabling concurrent protocol processing without CPU intervention. Its dual PLL architecture allows asynchronous operation: one PLL drives the G2 core (1.5× to 6× multiplier), another drives the CPM (2× to 6×), supporting power/performance optimization across mixed-workload systems.

It features a 64-bit 60x bus (up to 66 MHz) with burst transfer support, ECC/parity-capable memory controller for SDRAM/SRAM/Flash, and twelve programmable chip-select machines. The CPM provides three FCCs (10/100-Mbps Ethernet + UTOPIA), four SCCs (HDLC/UART/SDLC), two SMCs (GCI/TDM management), SPI, I²C, eight TDM interfaces, and 20 configurable baud rate generators.

Equivalent & Alternatives

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

Compared with MPC8272CZQHBC and MPC8360EVRAGDB, the XPC8260CVVIHBC offers proven reliability in temperature-stressed telecom environments but lacks hardware crypto and modern memory interfaces-making it optimal for cost-sensitive, functionally stable legacy deployments where upgrade path is not required.

Availability

XPC8260CVVIHBC is available at Aetrix Electronics and suitable for DSLAM line cards, industrial protocol gateways, and legacy telecom access routers requiring stable component supply and long-lifecycle support.

Supply support for XPC8260CVVIHBC includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Freescale Semiconductor (now part of NXP Semiconductors) was a pioneer in embedded communications processors, delivering high-integration SoCs for networking and industrial control before its 2015 acquisition.

The XPC8260CVVIHBC belongs to the PowerQUICC II family, designed specifically for deterministic real-time protocol processing in carrier-class access equipment-balancing G2 core compute with autonomous CPM offload for Ethernet, ATM, HDLC, and TDM workloads.

FAQ

What is the maximum operating junction temperature for the XPC8260CVVIHBC?

The XPC8260CVVIHBC has a maximum rated junction temperature of 105°C under recommended operating conditions. This limit assumes proper thermal design-including a 4-layer PCB with dedicated VDD/GND planes, thermal vias under the TBGA thermal pad, and airflow ≥1 m/s. Exceeding 105°C risks timing violations and accelerated electromigration in the HiP3 0.29 μm process. Derating is required above 70°C ambient if total power dissipation exceeds 3 W.

Does the XPC8260CVVIHBC support DDR SDRAM?

No, the XPC8260CVVIHBC does not support DDR SDRAM. Its memory controller supports only single-data-rate SDRAM (SDR SDRAM), as well as SRAM, DRAM, EPROM, and Flash. DDR support was introduced in the subsequent PowerQUICC III generation (e.g., MPC8360). For XPC8260CVVIHBC designs, page-mode SDR SDRAM is the highest-performance memory option, with configurable burst lengths and CAS latencies.

How many Ethernet MACs does the XPC8260CVVIHBC integrate?

The XPC8260CVVIHBC integrates three Fast Communications Controllers (FCC1–FCC3), each capable of implementing a full 10/100-Mbps Ethernet MAC when paired with an external PHY via MII. All three FCCs share the same register set and DMA resources but operate independently-enabling true tri-port Ethernet routing or redundant WAN/LAN interfaces in a single chip.

Can the XPC8260CVVIHBC run Linux?

Yes, the XPC8260CVVIHBC is capable of running Linux, and official kernel support (via Freescale's LSP v2.x) exists for both MMU-enabled and MMU-less configurations. However, due to its 200 MHz max clock speed and 16 KB caches, practical deployment is limited to lightweight distributions (e.g., uClinux or MontaVista CGE) targeting headless network appliances-not desktop or GUI workloads. Real-time patches are available for deterministic interrupt latency.

What is the purpose of the RSTCONF pin on the XPC8260CVVIHBC?

The RSTCONF pin on the XPC8260CVVIHBC enables extended clock configuration beyond the basic MODCK[1–3] settings. When asserted during HRESET, it unlocks 49 additional clock modes (vs. 8 default modes), allowing fine-grained selection of core and CPM frequencies-including non-integer multipliers like 2.5× and 3.5×. This pin must be driven by a stable logic level prior to release of HRESET to ensure correct PLL initialization.
