NXP Semiconductors MPC8247CZQMIBA

Overview

MPC8247CZQMIBA from NXP Semiconductors (formerly Freescale) is a PowerQUICC II integrated communications processor combining a 32-bit Power Architecture G2_LE core (266–400 MHz), dual Fast Communication Controllers (FCCs) for 10/100-Mbit Ethernet, three Serial Communication Controllers (SCCs), USB 2.0 full/low-speed controller, PCI bridge (32-bit, 66 MHz), and memory controller - deployed in telecom access equipment, industrial gateways, and legacy network infrastructure requiring deterministic real-time packet processing.

For engineers reviewing the MPC8247CZQMIBA datasheet, MPC8247CZQMIBA pinout, MPC8247CZQMIBA application, or MPC8247CZQMIBA equivalent, key selection criteria include its 516-pin PBGA (ZQ package), dual-voltage operation (1.425–1.575 V core / 3.135–3.465 V I/O), absence of integrated security engine (SEC), and compatibility with PowerQUICC II software toolchains and Linux BSPs targeting embedded networking.

Technical Context

The MPC8247CZQMIBA implements a dual-issue G2_LE core derived from the MPC603e microarchitecture, featuring separate 16 KB instruction and data caches (four-way set associative, physically addressed, LRU replacement) and a Power Architecture-compliant MMU. It integrates a modified Communications Processor Module (CPM) with dedicated 16 KB dual-port RAM and 4 KB instruction RAM, enabling offload of serial protocol handling (HDLC, UART, transparent, QMC) from the main CPU.

Its clock architecture uses independent PLLs for core and CPM domains, supporting configurable multiplication ratios (core: 2:1 to 8:1; CPM: 2:1 to 8:1), enabling power/performance tuning. The device supports 64-bit 60x bus (up to 133 MHz), 32-bit PCI interface (66 MHz), and glueless interfacing to SDRAM, SRAM, Flash, and EPROM via an eight-bank memory controller with programmable bank sizes and byte write enables.

FAQ

Does the MPC8247CZQMIBA include an integrated security engine (SEC)?

No, the MPC8247CZQMIBA does not include an integrated security engine. Unlike the MPC8248CZQMIBA and MPC8272CZQMIBA, this variant omits hardware acceleration for DES, 3DES, AES, SHA-1, MD-5, and RNG. Security functions must be implemented in software or via external crypto coprocessors when using the MPC8247CZQMIBA.

What is the maximum operating frequency of the G2_LE core in the MPC8247CZQMIBA?

The G2_LE core in the MPC8247CZQMIBA operates at 266–400 MHz, determined by the internal PLL multiplier ratio applied to the CLKIN signal. Valid ratios range from 2:1 to 8:1, allowing precise clock configuration to balance performance and power consumption for the target application.

Which package type does the MPC8247CZQMIBA use, and what are its mechanical dimensions?

The MPC8247CZQMIBA uses the ZQ package: a 516-ball Plastic Ball Grid Array with lead-sphere terminations, RoHS-compliant, measuring 27 mm × 27 mm with 1.0 mm ball pitch. This matches the VR package footprint but differs in solder sphere composition for reflow profile compatibility.

Can the MPC8247CZQMIBA support UTOPIA II interface for ATM applications?

No, the MPC8247CZQMIBA does not support UTOPIA II. That interface is exclusive to the MPC8272 and MPC8271 variants. The MPC8247CZQMIBA lacks the required 8-bit UTOPIA pins and ATM SAR logic, limiting its use to non-ATM protocols such as Ethernet, HDLC, and TDM.

What voltage levels are required for core and I/O operation of the MPC8247CZQMIBA?

The MPC8247CZQMIBA requires VDD = 1.425–1.575 V for the core and VDDH = 3.135–3.465 V for all I/O banks. These must be supplied independently with strict sequencing: VDD/VCCSYN should be established before or simultaneously with VDDH during power-on reset to avoid reliability issues.
