NXP Semiconductors MPC8247CVRMIBA

Overview

MPC8247CVRMIBA from NXP Semiconductors (formerly Freescale) is a PowerQUICC II family integrated communications processor combining a 32-bit Power Architecture® G2_LE core (266–400 MHz), dual Fast Communication Controllers (FCCs) for 10/100 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 MPC8247CVRMIBA datasheet, MPC8247CVRMIBA pinout, MPC8247CVRMIBA application, or MPC8247CVRMIBA equivalent, key selection criteria include its 516-pin PBGA (VR package), dual-voltage operation (1.5 V core / 3.3 V I/O), absence of integrated security engine (SEC), UTOPIA II port exclusion, and compatibility with PowerQUICC II software toolchains and Linux BSPs targeting embedded networking.

Technical Context

The MPC8247CVRMIBA implements a dual-issue G2_LE core derived from the MPC603e microarchitecture, featuring separate 16 KB instruction and 16 KB data caches (four-way set associative, physically addressed, LRU replacement), MMU support, and bus snooping for cache coherency. It integrates a modified Communications Processor Module (CPM) with dedicated 16 KB dual-port RAM and 4 KB instruction RAM for offloading protocol processing from the main core.

Its clock architecture employs independent PLLs for the G2_LE core and CPM, enabling asynchronous frequency scaling (core multipliers: 2:1 to 8:1; CPM multipliers: 2:1 to 8:1). The device supports 64-bit/32-bit 60x bus operation up to 133 MHz and includes a compliant PCI 2.2 bridge with four DMA channels, hot-swap capability, and I2O support - all without integrated encryption acceleration.

FAQ

Does MPC8247CVRMIBA include an integrated security engine (SEC)?

No, the MPC8247CVRMIBA does not include an integrated security engine. Unlike the MPC8248CVRMIBA and MPC8272CVRMIBA, this variant omits hardware acceleration for DES, 3DES, AES, SHA-1, and MD-5. Encryption tasks must be handled in software or via external co-processors. This omission reduces die size, power consumption, and cost - making MPC8247CVRMIBA appropriate for applications where cryptographic acceleration is unnecessary.

What is the maximum operating frequency of the G2_LE core in MPC8247CVRMIBA?

The G2_LE core in MPC8247CVRMIBA operates at frequencies ranging from 266 MHz to 400 MHz, determined by the CLKIN frequency and programmable core PLL multiplier (2:1 to 8:1). For example, a 50 MHz CLKIN with a 8:1 multiplier yields 400 MHz core operation. The device's DC and AC specifications are validated across this full range under recommended operating conditions (VDD = 1.425–1.575 V, TA = 0–70°C).

Which package type does MPC8247CVRMIBA use, and what are its mechanical dimensions?

MPC8247CVRMIBA uses the VR package: a 516-ball plastic ball grid array (PBGA), lead-free, compliant with JEDEC MO-205. Its body measures 27 mm × 27 mm with 1.0 mm ball pitch. The package features thermal resistance RθJA = 27°C/W (natural convection, single-layer board) and RθJB = 11°C/W, requiring careful PCB layout with thermal vias to ground planes for sustained 400 MHz operation.

Can MPC8247CVRMIBA support both PCI host and peripheral modes?

Yes, MPC8247CVRMIBA's integrated 60x-to-PCI bridge supports configurable host and peripheral modes via programmable registers. As a host, it controls external PCI devices (e.g., crypto accelerators or wireless modems); as a peripheral, it appears as a PCI target to an external x86 or ARM host. Mode selection is controlled through the PCI configuration space and requires initialization by boot firmware before OS loading.

What are the supported memory interface types for MPC8247CVRMIBA?

MPC8247CVRMIBA's eight-bank memory controller supports glueless interfacing to SRAM, page-mode SDRAM, DRAM, EPROM, and Flash memory. It provides 32-bit address decoding with programmable bank sizes, byte write enables, and dedicated SDRAM pipeline logic. Supported configurations include 32-bit-wide SDRAM with auto-refresh and burst-length control - verified up to 133 MHz bus speeds in the hardware specification.
