NXP Semiconductors MPC8248CZQMIBA-NXP

Overview

MPC8248CZQMIBA from NXP (formerly Freescale) is a 32-bit PowerQUICC II™ integrated communications processor featuring a 400 MHz G2_LE PowerPC core, dual 16-Kbyte instruction/data caches, integrated security engine (SEC), PCI bridge, and dual Fast Communication Controllers (FCCs) supporting 10/100-Mbit Ethernet. It targets secure network edge devices such as enterprise routers, firewall appliances, and VoIP gateways requiring hardware-accelerated encryption and deterministic real-time packet processing.

For engineers reviewing the MPC8248CZQMIBA datasheet, MPC8248CZQMIBA pinout, MPC8248CZQMIBA application, or MPC8248CZQMIBA equivalent, key selection considerations include SEC algorithm support (AES, DES, SHA-1, MD-5), 516-pin PBGA ZQ package thermal performance (RθJB = 11°C/W), PCI 2.2 compliance at 66 MHz, and dual-FCC MII/RMII interface timing under 133-MHz bus operation.

Technical Context

The MPC8248CZQMIBA implements a dual-issue G2_LE PowerPC core with separate 16-Kbyte physically addressed, four-way set associative caches and an MMU compliant with PowerPC architecture. Its CPM subsystem includes three SCCs, two FCCs, SPI, I²C, USB 2.0 full/low-speed controller, and eight baud rate generators - all clocked via independent PLLs for core and CPM frequency optimization.

Hardware security acceleration is provided by the integrated Security Engine (SEC), supporting AES, DES/3DES, SHA-1, MD-5, RC-4, PKEU, and RNG in dedicated logic. The 60x-to-PCI bridge operates at 32-bit/66 MHz with streaming DMA, configuration register auto-load from EPROM, and Hot-Swap compliance per PICMG 2.1 R1.0.

FAQ

What is the maximum operating frequency of the MPC8248CZQMIBA core?

The MPC8248CZQMIBA features a G2_LE PowerPC core rated for up to 400 MHz operation. This frequency is achieved using a 100 MHz CLKIN signal with a 4:1 internal core clock multiplier. Stable operation requires adherence to specified VDD (1.425–1.575 V) and ambient temperature (0–70°C) limits per the MPC8272EC Rev. 2 datasheet.

Does the MPC8248CZQMIBA include hardware encryption acceleration?

Yes, the MPC8248CZQMIBA integrates a dedicated Security Engine (SEC) supporting AES, DES/3DES, SHA-1, MD-5, RC-4, PKEU, and RNG algorithms in hardware. This SEC is confirmed in Table 1 of the MPC8272EC specification and is exclusive to the MPC8272 and MPC8248 variants within the family.

What package type does the MPC8248CZQMIBA use, and what are its thermal characteristics?

The MPC8248CZQMIBA uses a 516-ball PBGA package with ZQ code (lead-sphere construction). Its junction-to-board thermal resistance (RθJB) is 11°C/W, measured per JEDEC JESD51-8 on a 2s2p board. This enables reliable operation at 105°C junction temperature with appropriate PCB copper pour and ground plane design.

How many Ethernet interfaces does the MPC8248CZQMIBA support, and what PHY interfaces are available?

The MPC8248CZQMIBA supports two 10/100-Mbps Ethernet interfaces via its dual Fast Communication Controllers (FCCs). Each FCC provides MII and RMII PHY interfaces, allowing flexible connection to standard Ethernet transceivers. UTOPIA II is not supported on this variant, as confirmed in Table 1 of the MPC8272EC document.

Is the MPC8248CZQMIBA pin-compatible with other members of the MPC8272 family?

Yes, the MPC8248CZQMIBA shares identical pinout and package dimensions with other 516-ball ZQ/VR variants in the MPC8272 family (e.g., MPC8272ZQ, MPC8247ZQ). Pin compatibility is confirmed in Table 2 of the MPC8272EC specification, which lists MPC8248ZQ as a valid ordering option for the ZQ package.
