NXP Semiconductors MPC8245TZU333D

Overview

MPC8245TZU333D from Freescale Semiconductor is a 333 MHz integrated PowerPC™ MPC603e-based processor combining a CPU core and PCI bridge in a single TBGA package, operating at 2.0 V ±100 mV with junction temperature range –40°C to 105°C, used in legacy industrial control and telecom infrastructure systems requiring embedded processing with PCI interconnect.

For engineers reviewing the MPC8245TZU333D datasheet, MPC8245TZU333D pinout, MPC8245TZU333D application, or MPC8245TZU333D equivalent, key selection criteria include verified core frequency (333 MHz), VDD tolerance (±100 mV), extended temperature rating (–40°C to 105°C), TBGA package compatibility, and PCI bridge integration for host-bridge system partitioning.

Technical Context

The MPC8245TZU333D implements a superscalar PowerPC MPC603e core with 32 KB instruction and 32 KB data L1 cache, and integrates a full PCI 2.1-compliant bridge supporting 33 MHz/32-bit operation. It uses a dual-bus architecture separating CPU and PCI domains with configurable address translation and memory coherency support via software-managed snooping.

It supports external memory interfaces including SDRAM controller (up to 133 MHz), local bus (up to 100 MHz), and programmable chip selects for flash, SRAM, and peripherals. The device requires precise 2.0 V ±100 mV core supply and operates only within the –40°C to 105°C junction temperature envelope.

FAQ

What is the maximum guaranteed operating frequency of the MPC8245TZU333D?

The MPC8245TZU333D is factory-tested and guaranteed to operate at 333 MHz under all specified conditions, including VDD = 2.0 V ±100 mV and junction temperature from –40°C to 105°C. This frequency is encoded in the part number and confirmed by the Processor Version Register value 0x80811014. Operation above 333 MHz is not characterized or supported for the MPC8245TZU333D.

Does the MPC8245TZU333D support PCI Express?

No, the MPC8245TZU333D implements only PCI 2.1 specification (33 MHz, 32-bit parallel bus) and does not support PCI Express. Its PCI interface is strictly compliant with PCI Local Bus Specification Rev 2.1, with no lane enumeration, serial differential signaling, or link training capabilities. Designers requiring PCIe must select newer-generation processors outside the MPC8245 family.

What package type does the MPC8245TZU333D use, and is it RoHS-compliant?

The MPC8245TZU333D uses a 484-ball lead-free TBGA package designated by the "ZU" suffix, fully compliant with RoHS Directive 2002/95/EC. The package is marked per Freescale specification with "MPC8245T" prefix, frequency code "333", and revision "D", and requires standard Pb-free reflow profiles per J-STD-020.

Can the MPC8245TZU333D operate at temperatures below –40°C?

No, the MPC8245TZU333D is characterized and warranted only for junction temperatures from –40°C to 105°C. Operation below –40°C is outside the qualified range and may result in timing violations, increased leakage current, or failure to initialize. For sub–40°C applications, designers must perform full system-level validation and cannot rely on Freescale's published specifications for the MPC8245TZU333D.

What is the purpose of the Processor Version Register value 0x80811014 in the MPC8245TZU333D?

That value uniquely identifies the MPC8245TZU333D silicon revision and feature configuration per Freescale's internal versioning scheme. Bits [31:16] indicate the processor family (0x8081), bits [15:8] encode the mask set (0x10), and bits [7:0] specify the revision level (0x14). Firmware reads this register at boot to confirm compatibility and enable correct errata workarounds for the MPC8245TZU333D.
