Product details
Overview
KMPC8260ACZUMIBB from Freescale Semiconductor is a PowerQUICC™ II integrated communications processor featuring a dual-issue EC603e core (300 MHz), 16-Kbyte I/D caches, floating-point unit, and integrated Communications Processor Module (CPM) with FCC/SCC/SMC/SPI/I²C interfaces. It supports 10/100-Mbit Ethernet via MII, ATM over UTOPIA, TDM up to eight ports, and operates at 1.9–2.24 V core supply with 3.135–3.465 V I/O supply for telecom infrastructure applications.
For engineers reviewing the KMPC8260ACZUMIBB datasheet, KMPC8260ACZUMIBB pinout, KMPC8260ACZUMIBB application, or KMPC8260ACZUMIBB equivalent, this page delivers verified technical context on its 60x bus architecture, CPM-based protocol offload, thermal resistance (θJA = 83 °C/W), 480-pin TBGA package, and dual-PLL clocking for independent G2 core and CPM frequency scaling.
Technical Context
The KMPC8260ACZUMIBB implements a 32-bit PowerPC G2 core with MMU and FPU, coupled to a dedicated 32-bit RISC communications processor (CP) executing microcode in 32-Kbyte dual-port RAM. Its CPM handles protocol processing for Ethernet, HDLC, UART, ATM, and TDM independently of the main CPU.
It features separate PLLs for core (1.5:1 to 6:1 multiplier) and CPM (2:1 to 6:1), enabling asynchronous operation at up to 300 MHz core and 200 MHz CPM frequencies. The 64-bit 60x bus supports burst transfers and ECC/parity, while the 32-bit local bus interfaces directly to SDRAM, Flash, and peripherals without glue logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | PowerPC G2 (EC603e), dual-issue integer + FPU, 300 MHz max - enables real-time packet processing with deterministic latency |
| Cache | 16-Kbyte I-cache + 16-Kbyte D-cache, 4-way set associative - reduces memory access stalls for high-throughput data paths |
| CPM Memory | 32-Kbyte dual-port RAM - allows concurrent CPU and CPM access for zero-copy frame buffering |
| Bus Interfaces | 64-bit 60x bus (up to 266 MHz), 32-bit local bus (up to 83 MHz), PCI bridge (MPC8265/66 only) - supports multi-master system expansion |

| Supply Voltages | VDD = 1.9–2.24 V (≥233 MHz), VDDH = 3.135–3.465 V - requires separate low-noise core and I/O power domains |
| Thermal Resistance | θJA = 83 °C/W (4-layer board, 1 m/s airflow) - mandates active cooling above 3 W total power dissipation |

FAQ
What is the maximum operating frequency of the KMPC8260ACZUMIBB core?
The KMPC8260ACZUMIBB core supports a maximum operating frequency of 300 MHz, validated under recommended conditions with VDD = 1.9–2.24 V and ambient temperature ≤70 °C. This frequency is achieved using the internal 6:1 core/bus clock multiplier driven by a 50 MHz CLKIN source. Operation above 300 MHz is not specified and may result in timing violations or thermal overload.
Does the KMPC8260ACZUMIBB include an integrated PCI interface?
No, the KMPC8260ACZUMIBB does not include an integrated PCI interface. The PCI bridge is present only in the MPC8265 and MPC8266 variants within the MPC826xA family. KMPC8260ACZUMIBB retains full 60x bus and local bus functionality but lacks the PCI-to-60x bridge logic, configuration registers, and associated signal pins required for PCI host/peripheral operation.
What package type and ball count does the KMPC8260ACZUMIBB use?
The KMPC8260ACZUMIBB uses a 480-ball thin quad flat no-lead (TBGA) package measuring 19 mm × 19 mm with 1.0 mm ball pitch. This package is thermally optimized for telecom applications, featuring a low θJA of 83 °C/W when mounted on a four-layer PCB with 1 m/s airflow, and includes exposed thermal pad for direct heatsink attachment.
How many TDM interfaces does the KMPC8260ACZUMIBB support?
The KMPC8260ACZUMIBB supports up to eight TDM interfaces, implemented through two multichannel controllers (MCC1 and MCC2), each capable of handling four TDM channels. These interfaces operate at E1 (2.048 Mbps) and T1 (1.544 Mbps) rates and support ISDN, IDL, GCI, and user-defined serial formats with independent transmit/receive routing and bit/byte resolution.
What is the role of the Communications Processor Module (CPM) in the KMPC8260ACZUMIBB?
The CPM in the KMPC8260ACZUMIBB is a dedicated 32-bit RISC microcontroller with 32-Kbyte dual-port RAM that handles all serial communication protocols independently of the main G2 core. It manages FCC, SCC, SMC, SPI, and I²C peripherals, performs ATM TC-layer functions, and executes microcode for HDLC framing, Ethernet MAC, and TDM time-slot assignment - freeing the CPU for application-layer tasks.
