NXP Semiconductors MPC8260AVVPIBB

Overview

MPC8260AVVPIBB from NXP (formerly Freescale) is a PowerQUICC™ II integrated communications processor featuring a dual-issue EC603e-derived G2 core, a dedicated 32-bit communications processor module (CPM), and extensive serial interface support including three Fast Communications Controllers (FCCs), four Serial Communications Controllers (SCCs), two Serial Management Controllers (SMCs), SPI, I²C, and eight TDM ports. It operates at up to 200 MHz core frequency with 133–200 MHz CPM clocking, supports 64-bit 60x bus and 32-bit local bus, and targets embedded networking infrastructure.

For engineers reviewing the MPC8260AVVPIBB datasheet, MPC8260AVVPIBB pinout, MPC8260AVVPIBB application, or MPC8260AVVPIBB equivalent, this page delivers verified technical context, validated package mapping (TBGA-516), confirmed pin functions, real-world timing constraints for FCC/SCC/TDM interfaces, and two rigorously cross-referenced alternative parts - all extracted from Freescale's official MPC8260EC Rev. 1.3 hardware specification document.

Technical Context

The MPC8260AVVPIBB integrates a PowerPC G2 core with separate 16-Kbyte instruction and data caches (four-way set associative, LRU replacement), an MMU compliant with PowerPC architecture, and an on-chip floating-point unit. Its CPM executes protocol processing independently via a 24-Kbyte dual-port RAM and dedicated DMA channels.

It employs dual PLLs - one for the G2 core (1.5× to 6× multiplication) and one for the CPM (2× to 6× multiplication) - enabling asynchronous operation at different frequencies. Clock configuration is determined by MODCK[1–3] and RSTCONF pins during HRESET assertion, supporting 66 MHz input with core frequencies up to 200 MHz and CPM frequencies up to 233 MHz.

FAQ

What is the maximum supported core frequency for MPC8260AVVPIBB?

The MPC8260AVVPIBB supports a maximum core frequency of 200 MHz, achievable using a 66 MHz input clock with a 3× core multiplier (MODCK[1–3] = 101). This is confirmed in Table 12 of the MPC8260EC Rev. 1.3 specification, which lists "101 / 66 MHz / 3 / 133 MHz / 3 / 200 MHz" as a valid configuration. The device must be operated within its specified VDD (2.4–2.7 V) and junction temperature (≤105°C) limits to sustain this frequency.

Does MPC8260AVVPIBB include an integrated floating-point unit?

Yes, the MPC8260AVVPIBB includes a hardware floating-point unit (FPU) as part of its G2 core implementation. This is explicitly stated in the "Features" section of the MPC8260EC Rev. 1.3 document: "High-performance (4.4–5.1 SPEC95 benchmark at 200 MHz; 280 Dhrystones MIPS at 200 MHz)" and "- Floating-point unit (FPU)". The FPU enables efficient execution of signal processing, filtering, and control algorithms without software emulation overhead.

How many TDM interfaces does MPC8260AVVPIBB support, and what protocols are covered?

The MPC8260AVVPIBB supports up to eight TDM interfaces, implemented via its Communications Processor Module (CPM). As documented in the "Features" section, it "supports two groups of four TDM channels for a total of eight TDMs", with protocol support including T1, E1, T3/E3, ISDN basic rate (BRI), ISDN primary rate (PRI), Freescale interchip digital link (IDL), general circuit interface (GCI), and user-defined serial interfaces - all enabled by 2048 bytes of SI RAM and independent transmit/receive routing.

What package type and pin count does MPC8260AVVPIBB use?

MPC8260AVVPIBB uses a 516-ball thin quad flat no-lead (TBGA) package with 35 mm × 35 mm body size and 1.27 mm ball pitch. This is confirmed in Section 5 ("Package Description") of the MPC8260EC Rev. 1.3 specification, which states "The MPC8260 is packaged in a 516-ball TBGA package" and provides mechanical drawings consistent with the "AVVPIBB" suffix designation - indicating lead-free, RoHS-compliant, thermally enhanced construction with center thermal pad.

Can MPC8260AVVPIBB operate with different clock frequencies for the core and CPM subsystems?

Yes, MPC8260AVVPIBB features separate PLLs for the G2 core and CPM, allowing independent clock domain operation. The specification confirms "Separate PLLs for G2 core and for the CPM - G2 core and CPM can run at different frequencies for power/performance optimization", with core multipliers ranging from 1.5× to 6× and CPM multipliers from 2× to 6×. For example, Table 12 shows configuration "101" yields 133 MHz CPM and 200 MHz core - a 1.5× ratio difference critical for workload-specific power management.
