MPC8545PXATGD557 概覽

The `MPC8545PXATGD557` from `NXP Semiconductors` is a PowerQUICC III family microprocessor based on the PowerPC `e500` core, operating at 1.2 GHz with a 32-bit datapath, housed in a 783-pin FCPBGA (29 mm x 29 mm) package. The part integrates a single e500 core with double-precision floating-point support, 32 KB instruction and 32 KB data L1 caches, and a unified 256 KB L2 cache. System-on-chip integration includes a 64-bit DDR memory controller, four Gigabit Ethernet MACs, two PCI/PCI-X controllers, a local bus controller, and integrated security engines. Designed for high-performance networking and embedded control, the MPC8545 targets routers, switches, line cards, and storage controllers where deterministic throughput and rich I/O are required. The "PX" suffix in the MPN indicates the PowerQUICC III family, the "ATG" suffix denotes a 1.2 GHz speed grade, and the "D557" marking corresponds to NXP's part identifier scheme. Typical applications include enterprise networking line cards, storage controllers, industrial routers, and secure communications gateways. The wide I/O integration reduces external component count and BOM cost. Design considerations include proper PCB stack-up for the large 783-ball BGA, thermal management for the high-power core, and firmware support via U-Boot, VxWorks, or Linux BSPs. This page synthesizes distributor stock, pricing, and cross-brand drop-in alternatives not found in the manufacturer datasheet.

What is the operating frequency of the MPC8545PXATGD557?

The MPC8545PXATGD557 runs at a maximum core clock frequency of 1.2 GHz on the PowerPC e500 core. The "ATG" speed-grade suffix in the MPN denotes this 1.2 GHz grade within the PowerQUICC III family, per NXP's part numbering scheme. The same MPC8545 silicon die is also offered in lower speed grades such as "A" and "ATG" variants for design flexibility.

How many cores does the MPC8545PXATGD557 have and what is the cache hierarchy?

The MPC8545PXATGD557 is a single-core PowerQUICC III microprocessor based on the e500 core. Cache configuration per NXP documentation: 32 KB 8-way instruction L1, 32 KB 8-way data L1, and a 256 KB unified backside L2 cache. The e500 core includes a double-precision floating-point unit and supports Book-E instruction set extensions for embedded deterministic behavior.

What package does the MPC8545PXATGD557 ship in?

The MPC8545PXATGD557 is packaged in a 783-ball Flip-Chip Plastic BGA (FCPBGA) measuring 29 mm by 29 mm, per NXP's package designation. The large 1.06 mm pitch BGA requires a multi-layer PCB with microvia stack-up for reliable assembly. The 783-FCPBGA package is the only package option offered for this MPN.

What integrated peripherals are inside the MPC8545PXATGD557?

According to NXP's MPC8545 product documentation, the SoC integrates a 64-bit DDR/DDR2 memory controller, four tri-speed Gigabit Ethernet MACs with on-chip SerDes, two PCI/PCI-X controllers (one 64-bit, one 32-bit), an 8/16/32-bit local bus controller, four DMA channels, two I2C controllers, a DUART, and integrated security engines for symmetric/asymmetric crypto acceleration. This SoC integration reduces BOM and board area for networking designs.

Where can I buy the MPC8545PXATGD557 and what does it cost?

As of 2026-10-17, the MPC8545PXATGD557 is available from authorized distributors including Rochester Electronics, LCSC, and JLCPCB, with authorized distributor stock. The target landing page price starts at approximately $95.00 USD for single-unit quantities, with volume discounts bringing the qty-500 unit price to about $74.50 USD. Lead time varies; contact your distributor for current availability.

What is the lead time for the MPC8545PXATGD557?

Lead time for the MPC8545PXATGD557 as of 2026-10-17 typically ranges from 8 to 14 weeks when ordered through authorized distributors, given the part's NCNR/NRND status. Rochester Electronics maintains long-term stock of this device for legacy designs. For volume production we recommend confirming allocation with your distributor at the time of RFQ, as the part may be subject to last-time-buy restrictions.

Is the MPC8545PXATGD557 in stock today?

As of 2026-10-17 the MPC8545PXATGD557 shows in-stock at LCSC (qty-1 from $95.00 USD) and through Rochester Electronics, with additional franchised distributor listings on JLCPCB and Octopart. Because the part is in NCNR/NRND status with limited remaining inventory, we recommend ordering ahead of forecast to avoid supply gaps.

What is the difference between the MPC8545PXATGD557 and the MPC8545PXANGD557?

The MPC8545PXANGD557 typically denotes a lower speed grade variant of the same MPC8545 PowerQUICC III silicon. The "ATN" suffix indicates a slower speed bin (commonly 1.0 GHz), whereas "ATG" denotes the 1.2 GHz grade. Both variants share the same 783-FCPBGA footprint and pin-out, making them functionally drop-in compatible if timing closure is verified at the lower frequency.

Can the P2020 or P2010 be used as a drop-in replacement for the MPC8545PXATGD557?

The NXP P2020 and P2010 are QorIQ-based successors in a different ball-out (TEPBGA vs FCPBGA), so they are not pin-compatible drop-in replacements for the MPC8545PXATGD557. They are, however, software-compatible within the same Book-E/e500 family and are often used as migration targets when designers move from PowerQUICC III to QorIQ architectures.

MPC8545PXATGD557 vs P2020 - which is better for a new network line card design?

For a new line card design starting in 2026, the NXP P2020 (1.2 GHz dual-core e500v2 in 780-TEPBGA) is generally preferred over the NCNR MPC8545PXATGD557 because it is active, offers dual cores, and has current Linux/VxWorks BSP support. The MPC8545 remains the right choice only for legacy designs where existing firmware must be preserved and the existing 783-FCPBGA PCB layout is fixed.

When should I choose the MPC8545PXATGD557 over a QorIQ alternative?

Choose the MPC8545PXATGD557 only for legacy designs where the existing PCB layout is fixed to a 783-FCPBGA footprint or where firmware has been certified against the MPC8545 silicon. For new designs, NXP's active QorIQ P2020/P2040 family is preferred. The MPC8545's lifecycle status is NCNR/NRND, so last-time-buy planning is critical.

What is the best drop-in replacement for the MPC8545PXATGD557?

There is no fully pin-compatible drop-in replacement for the MPC8545PXATGD557 in active production today, per NXP's roadmap. The closest migration targets are the QorIQ P2020, P2010, and P2040 families in different packages (TEPBGA), which require PCB rework. For supply continuity on the same 783-FCPBGA footprint, Rochester Electronics holds long-term stock of the original part.

Where can I download the MPC8545PXATGD557 datasheet?

The official NXP MPC8545 datasheet (Integrated Host Processor Hardware Specifications document) is available as a free PDF at https://www.nxp.com/docs/en/data-sheet/MPC8545.pdf. The document covers the full PowerQUICC III family including the MPC8545, MPC8545E, MPC8555, MPC8555E, MPC8560 variants. Always reference the latest revision from NXP for errata and AC timing.

Where can I find the MPC8545PXATGD557 pinout and ball map?

The MPC8545PXATGD557 pinout (783-FCPBGA ball map) is documented in the NXP MPC8545 Hardware Specifications manual available at https://www.nxp.com/docs/en/data-sheet/MPC8545.pdf. The document includes the top-view ball map, signal multiplexing tables, and pin grouping by function (DDR, Ethernet, PCI, local bus, etc.). Cross-reference the device's Rev/CVT mask set in your inventory against the manual revision before routing.

What is the difference between MPC8545 and MPC8555?

The MPC8545 and MPC8555 are siblings within the PowerQUICC III family. The MPC8545E adds integrated security engines (SEC 2.0) for crypto acceleration, while the standard MPC8545 does not include the security block. Both share the same 1.2 GHz maximum e500 core and 783-FCPBGA package, but software must verify which features are enabled in the specific silicon revision.

設計說明

The 783-FCPBGA package uses a 1.06 mm ball pitch, which requires a multi-layer PCB with laser-drilled microvias or stacked-via technology for the breakout layer. Recommended stack-up: 8+ layers with dedicated ground/power planes under the BGA. Use HDI design rules (line/space 4 mil/4 mil minimum) and ensure the BGA breakout fan-out is symmetrical on all four sides. Refer to NXP AN-2800 for FCPBGA layout guidelines.

The MPC8545PXATGD557 can dissipate 8-12 W at 1.2 GHz under typical networking workloads. A thermal pad or heat spreader must be attached to the top of the package using a thermal interface material (TIM). For conduction-cooled applications (VME/CompactPCI), a thermal pad on the lid with a minimum 2 C/W interface is required. Air-cooled designs should provide 200 LFM airflow across the heatsink.

Do not assume the security engine is present in all MPC8545 variants - the standard MPC8545 lacks SEC 2.0. If your firmware uses crypto acceleration, verify the silicon revision (MPC8545E = with SEC; MPC8545 = without). Also confirm the DDR memory topology: the MPC8545 supports only DDR/DDR2, not DDR3. Mixing DIMM types will damage the controller.

Design the core voltage rail (Vdd) at 1.1 V typical with +/-5% tolerance and a peak current capability of 4-5 A during core bursts. Use a multi-phase PWM controller with output inductors rated for at least 6 A saturation. Place decoupling capacitors within 2 mm of every Vdd/Vss pair, with a mix of 0.1 uF, 1 uF, and 10 uF bulk caps.

The DDR2 controller supports up to 533 MHz with 64-bit data plus ECC. Match trace lengths to within +/-25 mils for the data/strobe groups and use matched-impedance routing (50 ohm single-ended, 100 ohm differential for strobes). Place the DDR termination resistors as close as possible to the DRAM to prevent signal reflections.
