Product details
Overview
MPC8265ACZUMIBC from NXP Semiconductors (formerly Freescale) is a PowerQUICC™ II integrated communications processor featuring a dual-issue EC603e core running up to 300 MHz, integrated 60x-to-PCI bridge (32-bit, 66 MHz), and a dedicated Communications Processor Module (CPM) with FCCs, SCCs, SMCs, SPI, I²C, and TDM support. It targets telecom edge routers, ATM access concentrators, and industrial protocol gateways requiring deterministic real-time packet processing.
For engineers reviewing the MPC8265ACZUMIBC datasheet, MPC8265ACZUMIBC pinout, MPC8265ACZUMIBC application, or MPC8265ACZUMIBC equivalent, this page delivers verified electrical specs, thermal limits, PCI bridge timing, CPM peripheral mapping, and validated alternative selections for embedded communications hardware design.
Technical Context
The MPC8265ACZUMIBC implements a split-clock architecture with independent PLLs for its G2 core (150–300 MHz) and CPM (up to 200 MHz), enabling power/performance optimization. Its 60x bus operates at 64-bit width with burst transfers and ECC/parity support, while the local bus provides 32-bit glueless interface to SDRAM, Flash, and peripherals.
It integrates a full-featured CPM with three Fast Communications Controllers (FCC1–FCC3), four Serial Communications Controllers (SCC1–SCC4), two Serial Management Controllers (SMC1–SMC2), eight TDM interfaces, and UTOPIA Level 2 support - all managed via 32 KB dual-port RAM and microcode-driven virtual DMA channels.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | PowerPC G2 (EC603e), dual-issue integer core with FPU, MMU, and 16 KB I/D caches |
| Max Core Frequency | 300 MHz - enables >1.9 Dhrystone MIPS/MHz for real-time protocol stack execution |
| PCI Interface | 32-bit, 66 MHz, 3.3 V compliant - supports host/agent mode and four DMA channels for streaming transfers |

| TDM Interfaces | 8 independent TDM ports - supports T1/E1, ISDN PRI/BRI, ATM IMA, and custom time-slot assignment |
| Supply Voltages | VDD = 1.7–2.24 V (core), VCCSYN = 1.7–2.24 V (PLL), VDDH = 3.135–3.465 V (I/O) - requires tracking within ±5% + 0.1 V |
| Thermal Resistance | θJA = 83 °C/W (4-layer board, 1 m/s airflow) - mandates heatsink above 3 W total power dissipation at TA ≥ 70 °C |

Equivalent & Alternatives
The following parts are listed as comparable options for similar integrated communications processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC8272CZUMIB | Higher core frequency (400 MHz), added security engine (SEC), no PCI bridge - uses different memory controller and pinout | Targets secure VPN gateways and crypto-accelerated firewalls where PCI connectivity is unnecessary | Select when cryptographic offload and higher CPU throughput outweigh loss of PCI interface and require new PCB layout |
| MPC8313EVRAGDB | PowerPC e300 core (400 MHz), integrated DDR2 controller, USB 2.0, no CPM - replaces CPM with QUICC Engine block supporting similar protocols | Suitable for next-gen industrial routers needing USB device/host, DDR2 memory, and lower power consumption | Choose for migration paths requiring modern peripherals and reduced thermal footprint; not pin-compatible - requires firmware and layout redesign |
Compared with MPC8265ACZUMIBC, MPC8272CZUMIB offers stronger compute and security but removes PCI and changes memory interface, while MPC8313EVRAGDB shifts to DDR2 and QUICC Engine with USB - both require board redesign and software adaptation due to architectural divergence.

FAQ
What is the maximum supported core frequency for the MPC8265ACZUMIBC?
The MPC8265ACZUMIBC supports a maximum core frequency of 300 MHz, confirmed by Freescale's MPC8260AEC Rev. 2.0 specification document (Table 5, "Estimated Power Dissipation"). At this speed, it delivers 1.90 Dhrystone MIPS/MHz with VDD = 1.9–2.24 V and junction temperature ≤105 °C. Operation above 300 MHz is not characterized or guaranteed.
Does the MPC8265ACZUMIBC include an integrated PCI bridge?
Yes, the MPC8265ACZUMIBC includes a fully compliant PCI 2.2 bridge supporting 32-bit, 66 MHz operation, host/peripheral modes, and four dedicated DMA channels. This feature is explicitly confirmed in the "Features" section of the MPC8260AEC Rev. 2.0 document and applies only to MPC8265 and MPC8266 variants - not to MPC8255 or MPC8260.
How many TDM interfaces does the MPC8265ACZUMIBC support?
The MPC8265ACZUMIBC supports eight independent TDM interfaces, as stated in the "Features" section of the MPC8260AEC Rev. 2.0 document. These are implemented via the CPM's SI RAM and TC layer hardware, enabling simultaneous T1/E1, ISDN, and ATM IMA applications with bit-resolution framing and independent Tx/Rx routing.
What are the required supply voltage ranges for MPC8265ACZUMIBC operation?
The MPC8265ACZUMIBC requires three distinct supply rails: VDD (core) = 1.7–2.24 V, VCCSYN (PLL) = 1.7–2.24 V, and VDDH (I/O) = 3.135–3.465 V. Per Table 2 of MPC8260AEC Rev. 2.0, these voltages must track within ±5% and ±0.1 Vdc during all operating conditions, including power-on reset.
Is the MPC8265ACZUMIBC pin-compatible with other PowerQUICC II devices like the MPC8260?
No, the MPC8265ACZUMIBC is not pin-compatible with the MPC8260 or MPC8255. While sharing the same 480-pin TBGA package outline, its pin assignments differ significantly - especially for PCI signals (e.g., PCI_AD[0–31], PCI_CBE[0–3]), DP control pins, and CPM I/O banks - as documented in Section 4 ("Pinout") of MPC8260AEC Rev. 2.0.
