MPC8247CZQMIBA - PowerQUICC II 266MHz MPU | NXP | 516-PBGA
The NXP MPC8247CZQMIBA is a PowerQUICC II integrated communications processor built around a PowerPC 603e core, integrating one 32-bit core running at 266 MHz with a 32 KB instruction cache, 32 KB data cache, and a separate RISC Communications Processor Module (CPM) that offloads networking tasks from the main CPU. It is packaged in a 516-ball PBGA (27x27 mm) with a stated industrial temperature range of -40C to +105C, and is supplied in a version without TALITOS security acceleration, targeted at cost-sensitive networking equipment.
A microprocessor (MPU) in this category is a system-on-chip that combines a CPU core, memory controllers, peripheral interfaces, and dedicated acceleration blocks into one device; the PowerQUICC II family is part of the broader embedded microprocessor taxonomy that sits above microcontrollers in integration density. PowerQUICC II specifically targets wireline and wireless communications and is recognized as a legacy architecture that integrated an Ethernet MAC, ATM support, PCI, I2C, USB, and a multi-channel HDLC controller in a single chip, allowing designers to build routers, bridges, and access devices with very few external components.
Key features of this MPN include operation at 266 MHz core frequency, integrated SDRAM controller supporting up to 1 GB of addressable memory, two 10/100 Mbps Ethernet controllers, USB 1.1 interface, PCI 2.2 host/agent bridge, and I2C plus UART ports. Operating voltages are 1.5 V for the core and 3.3 V for I/O, and the device is supplied in a 516-PBGA package with industrial -40C to +105C temperature support.
Architecture combines a 603e core, the CPM co-processor running at a separate 200 MHz frequency, on-chip SRAM, dual-channel DDR or SDRAM memory controller, and peripheral bridges. The CPM contains RISC engines dedicated to fast protocol processing (Fast Ethernet, HDLC, ATM, USB) so the main CPU spends cycles on application code, not on bit-banging serial protocols.
Typical applications include small/medium enterprise routers, VPN/firewall gateways, wireless access points, residential gateways, and industrial networking controllers; the device also fits DSLAM line cards, print server controllers, and Power-over-Ethernet switches. The wide industrial temperature range plus absence of TALITOS makes this specific variant attractive for non-cryptographic network appliances.
Design consideration: board layout must include a 33 MHz PCI clock source, proper SDRAM trace length matching (within the data sheet tolerance), and adequate decoupling. Because the 603e core runs hot at 266 MHz, the 516-PBGA thermal pad must be soldered to a continuous ground plane with thermal vias for production environments.
