NXP Semiconductors MPC8247CZQTIEA

Overview

MPC8247CZQTIEA from Freescale Semiconductor is a PowerQUICC II integrated communications processor featuring a 32-bit Power Architecture® G2_LE core (266–400 MHz), dual 16 KB instruction/data caches, PCI bridge (32-bit, 66 MHz), two Fast Communication Controllers (FCCs) for 10/100 Ethernet, three Serial Communication Controllers (SCCs), USB 2.0 full/low-speed controller, and integrated security engine (SEC) support - deployed in telecom access gateways and industrial protocol converters.

For engineers reviewing the MPC8247CZQTIEA datasheet, MPC8247CZQTIEA pinout, MPC8247CZQTIEA application, or MPC8247CZQTIEA equivalent, key selection criteria include its 516-pin PBGA (ZQ package), dual-clock domain architecture (separate PLLs for CPU and CPM), 1.5 V core / 3.3 V I/O supply scheme, IEEE 802.3-compliant MII/RMII interfaces, and SEC acceleration for AES/DES/SHA-1.

Technical Context

The MPC8247CZQTIEA implements a dual-issue G2_LE core derived from the MPC603e microarchitecture, with physically addressed, four-way set-associative 16 KB I-cache and D-cache, and a Power Architecture-compliant MMU. It integrates a dedicated communications processor module (CPM) running a 32-bit RISC microcontroller with 16 KB data RAM and 4 KB instruction RAM, enabling offload of serial protocol handling including HDLC, UART, and transparent modes.

Its clocking architecture features independent PLLs for the G2_LE core and CPM, supporting configurable multiplication ratios (core: 2:1 to 8:1; CPM: 2:1 to 8:1), allowing asynchronous operation for power/performance tuning. The 60x bus provides 64-bit data width at up to 133 MHz, interfacing with external memory via an eight-bank memory controller supporting SDRAM, SRAM, Flash, and EPROM.

FAQ

What is the maximum operating junction temperature for the MPC8247CZQTIEA?

The MPC8247CZQTIEA has a maximum rated junction temperature of 105°C under recommended operating conditions. This limit applies to commercial temperature grade devices (0°C to 70°C ambient). Thermal design must ensure TJ ≤ 105°C using the specified RθJA = 19°C/W (four-layer board, natural convection) or lower RθJB = 11°C/W for board-conducted heat dissipation. Exceeding this temperature risks permanent reliability degradation.

Does the MPC8247CZQTIEA support PCIe or only legacy PCI?

The MPC8247CZQTIEA supports only PCI Specification Revision 2.2 - a 32-bit, 33/66 MHz parallel bus interface - and does not implement PCIe (PCI Express) physical or link layers. Its PCI bridge operates in synchronous or asynchronous 60x/PCI clock modes, provides four DMA channels, and supports host/agent configurations per the PCI 2.2 standard. PCIe capability was introduced in later PowerQUICC III and QorIQ families.

Is the security engine (SEC) in the MPC8247CZQTIEA identical to that in the MPC8248CZQTIEA?

Yes, the MPC8247CZQTIEA and MPC8248CZQTIEA share identical security engine (SEC) hardware: both support DES, 3DES, AES (128/192/256), SHA-1, MD-5, RC-4, PKEU, and RNG acceleration. The SEC implementation, register map, and driver compatibility are functionally equivalent. The distinction lies solely in peripheral sets - MPC8248 adds UTOPIA II and enhanced ATM SAR, not SEC enhancements.

Can the MPC8247CZQTIEA's USB 2.0 controller operate in device mode with full-speed capability?

Yes, the MPC8247CZQTIEA USB 2.0 controller fully supports device (peripheral) mode at full speed (12 Mbps), including control, bulk, interrupt, and isochronous transfer types. It provides four independent endpoints, CRC5/CRC16 checking, NRZI encoding/decoding with bit stuffing, and automatic retransmission on transmit errors - meeting USB 2.0 specification requirements for peripheral operation without requiring external transceivers.

What boot sources are supported by the MPC8247CZQTIEA during reset initialization?

The MPC8247CZQTIEA supports booting from multiple sources via its memory controller: 8-bit or 16-bit NOR Flash (mapped to CS0), 32-bit SDRAM (CS1–CS5), or 8-bit NAND Flash (via GPIO-controlled interface). Boot configuration is determined by strap pins (RSTCONF, BADDR[27–31]) sampled at power-on reset. Internal boot ROM initializes the CPM and configures essential clocks before loading firmware from the selected external source.
