NXP Semiconductors MPC8245TZU350D

Overview

MPC8245TZU350D from Freescale Semiconductor is a 350 MHz integrated PowerPC™ MPC603e-based processor with on-chip PCI bridge, designed for embedded control and communications applications requiring high integration, deterministic real-time response, and PCI host interface capability. It operates at 1.9–2.2 V core supply and supports –40°C to +105°C junction temperature.

For engineers reviewing the MPC8245TZU350D datasheet, MPC8245TZU350D pinout, MPC8245TZU350D application, or MPC8245TZU350D equivalent, key selection considerations include verified core frequency (350 MHz), TBGA package type (ZU), extended temperature range, PCI bridge functionality, and PowerPC 603e instruction set compatibility.

Technical Context

The MPC8245TZU350D implements a superscalar, three-stage pipeline PowerPC 603e core with 16 KB instruction and 16 KB data L1 cache, tightly coupled to a PCI-to-processor bridge that supports PCI 2.2-compliant 33 MHz, 32-bit bus mastering and memory-mapped I/O transactions. It integrates memory controller logic for SDRAM/SDRAM and local bus peripherals.

Its architecture enables single-chip system-on-module designs where the processor core handles application code execution while the integrated PCI bridge manages peripheral expansion, DMA transfers, and host-side communication-eliminating need for external bridge logic in compact industrial controllers and telecom line cards.

Manufacturer

Freescale Semiconductor was a fabless semiconductor company specializing in embedded processors, analog, and connectivity solutions before its acquisition by NXP Semiconductors in 2015. It pioneered PowerPC-based integrated processors for industrial and communications markets.

The MPC8245 product line was engineered to deliver single-chip PowerPC computing with integrated PCI bridging for space-constrained, high-reliability embedded systems-targeting applications where minimizing external logic, ensuring thermal robustness, and maintaining software compatibility were critical design goals.

FAQ

What is the maximum guaranteed operating frequency of the MPC8245TZU350D?

The MPC8245TZU350D is fully characterized and guaranteed to operate at 350 MHz under specified conditions: core voltage 1.9–2.2 V and junction temperature –40°C to +105°C. This frequency is confirmed in Freescale's MPC8245 Hardware Specification Addendum Rev. 1.1 and corresponds to the "350" suffix in the part number. The MPC8245TZU350D does not support overclocking beyond this rated speed without violating electrical and thermal specifications.

Does the MPC8245TZU350D support PCI Express or only legacy PCI?

The MPC8245TZU350D supports only PCI 2.2-compliant 33 MHz, 32-bit parallel bus operation-not PCI Express. Its integrated bridge implements conventional PCI signaling, arbitration, and configuration space access. The MPC8245TZU350D lacks PCIe PHY, link training, or serial lane infrastructure; any PCIe interface would require an external PCIe-to-PCI bridge, which is not supported by the MPC8245TZU350D's native architecture.

Is the MPC8245TZU350D pin-compatible with other MPC8245 variants like MPC8245TVV350D?

Yes-the MPC8245TZU350D and MPC8245TVV350D share identical pinout and ball map within the 480-ball TBGA footprint. Both use the same mechanical outline and signal assignment per Freescale's MPC8245 Integrated Processor Hardware Specifications. The only physical difference is ZU (lead-free) versus VV (leaded) solder composition; no PCB redesign is needed when substituting between them, though reflow profiles must be adjusted accordingly.

What does the 'T' and 'ZU' in MPC8245TZU350D signify?

In MPC8245TZU350D, 'T' denotes extended temperature grade (–40°C to +105°C), and 'ZU' specifies the lead-free thin ball grid array package per Freescale's part numbering convention. The '350' indicates maximum core frequency of 350 MHz, and 'D' is the revision level. These identifiers are defined in Section 9.3 ("Part Marking") and Table A of the MPC8245 Hardware Specification Addendum Rev. 1.1.

Can the MPC8245TZU350D execute PowerPC e300 or Book E instructions?

No-the MPC8245TZU350D implements the original PowerPC 603e core architecture, which supports the PowerPC Book III (32-bit user mode) and Book II (MMU) instruction sets-but not e300 or Book E extensions. It lacks the enhanced branch prediction, variable-length encoding, or SPE/AltiVec units introduced in later cores. Software targeting MPC8245TZU350D must be compiled for PowerPC 603e compatibility, not e300 or Book E.
