NXP Semiconductors MPC8247ZQTIEA

Overview

MPC8247ZQTIEA 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 memory controller - deployed in telecom access equipment, industrial gateways, and network edge routers.

For engineers reviewing the MPC8247ZQTIEA datasheet, MPC8247ZQTIEA pinout, MPC8247ZQTIEA application, or MPC8247ZQTIEA 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 1149.1 JTAG debug support, and absence of integrated security engine (SEC) - distinguishing it from MPC8272/MPC8248 variants.

Technical Context

The MPC8247ZQTIEA implements a dual-issue G2_LE core derived from the MPC603e microprocessor, with physically addressed, four-way set-associative caches and a compliant MMU. Its communications subsystem uses a dedicated 32-bit RISC CPM with 16 KB dual-port RAM and 4 KB instruction RAM, decoupled from the CPU via DMA and shared memory.

AC timing supports 66–133 MHz bus operation with configurable clock multipliers (CPU: 2×–8×; CPM: 2×–8×), while DC characteristics specify 1.425–1.575 V core voltage, 3.135–3.465 V I/O voltage, and thermal resistance R_θJA = 27 °C/W (single-layer board, natural convection). The device lacks SEC hardware and UTOPIA II interface - confirmed across Table 1 and Figure 1 annotations.

FAQ

Does MPC8247ZQTIEA include an integrated security engine (SEC)?

No, MPC8247ZQTIEA does not include an integrated security engine. As confirmed in Table 1 and Figure 1 notes, SEC hardware is present only in MPC8272 and MPC8248 variants. The MPC8247ZQTIEA relies on software-based encryption or external crypto accelerators for security functions, making it suitable for applications where hardware acceleration is not required.

What is the maximum operating frequency of the G2_LE core in MPC8247ZQTIEA?

The G2_LE core in MPC8247ZQTIEA operates at frequencies ranging from 266 MHz to 400 MHz, as specified in Section 1.1 "Features" and Table 8 power dissipation data. This range is achieved using configurable internal clock multipliers (2× to 8×) driven by the CLKIN input, with actual frequency dependent on board-level clock configuration and thermal conditions.

Which package type does MPC8247ZQTIEA use, and what are its mechanical dimensions?

MPC8247ZQTIEA uses the ZQ package: a 516-ball PBGA with lead-sphere termination, as defined in Table 2. Its mechanical footprint is 27 mm × 27 mm with 1.0 mm ball pitch. The ZQ variant differs from VR (lead-free) only in solder sphere composition - both share identical pinout, thermal profile, and mounting requirements.

Can MPC8247ZQTIEA support UTOPIA II interface for ATM applications?

No, MPC8247ZQTIEA does not support UTOPIA II. Table 1 explicitly lists UTOPIA II Ports as "0" for MPC8247, contrasting with "1" for MPC8272 and MPC8271. This omission is consistent across all documentation - confirming that ATM SAR functionality and associated UTOPIA pins are excluded from the MPC8247ZQTIEA silicon.

What are the supported bus interfaces and their electrical specifications for MPC8247ZQTIEA?

MPC8247ZQTIEA supports three primary buses: (1) 64-bit 60x bus (up to 133 MHz, 1.5 V core logic), (2) 32-bit PCI bus (66 MHz, 3.3 V, PCI Spec 2.2 compliant), and (3) memory controller bus (glueless SDRAM/Flash/SRAM). DC specs require VDD = 1.425–1.575 V and VDDH = 3.135–3.465 V, with VIH ≥ 2.0 V and VOL ≤ 0.4 V under specified load conditions.
