NXP Semiconductors XPC8240LZU200E

Overview

XPC8240LZU200E from Freescale Semiconductor is a pilot-production prototype integrated processor combining PowerPC MPC603e core and PCI-to-PCI bridge logic in a single TBGA package. It operates at 200 MHz CPU frequency with 2.625 V ±5% core supply, supports 66 MHz PCI bus and 100 MHz memory bus, and targets embedded control applications requiring deterministic real-time response and legacy PCI expansion.

For engineers reviewing the XPC8240LZU200E datasheet, XPC8240LZU200E pinout, XPC8240LZU200E application, or XPC8240LZU200E equivalent, key selection criteria include verified PLL configuration support for 200 MHz operation, thermal junction range of 0–105°C, TBGA-480 package compatibility, and power management modes (Doze/Nap/Sleep) with sub-watt idle consumption.

Technical Context

The XPC8240LZU200E implements dual-phase PLL architecture: one VCO for peripheral/memory bus clock generation (PCI-to-Mem multiplier), another for CPU clock derivation (Mem-to-CPU multiplier). PLL_CFG[0:4] pins configure both multipliers simultaneously, with HID1[0:4] register reflecting only the CPU-side ratio.

It integrates MPC603e core with 32 KB instruction + 32 KB data cache, PCI controller compliant with PCI Rev 2.2, and memory controller supporting SDRAM. Power domains are segregated: VDD/AVDD/AVDD2/LAVDD at 2.625 V, OVDD/GVDD at 3.3 V, LVDD at 5.0 V or 3.3 V, with strict voltage sequencing constraints during power-up/down.

FAQ

What does the "X" prefix in XPC8240LZU200E signify?

The "X" prefix in XPC8240LZU200E indicates a pilot production prototype per Freescale SOP 3-13. These parts undergo qualified manufacturing and QA inspection but carry only preliminary reliability and characterization data. Customers must provide written authorization acknowledging the prototype status and potential for future product changes before shipment. XPC8240LZU200E remains fully functional for design validation and low-volume integration.

Is XPC8240LZU200E pin-compatible with other MPC8240 variants?

Yes, XPC8240LZU200E uses the TBGA-480 package and shares identical pinout with all RZU-suffixed MPC8240 parts, including XPC8240RZU250E and MPC8245RZUP200B. The "ZU" designation confirms TBGA packaging, and Freescale's part numbering nomenclature (Table 19) guarantees mechanical and electrical pin compatibility across this family. Signal assignments and power domain connections remain consistent.

What PLL configuration supports 200 MHz operation for XPC8240LZU200E?

XPC8240LZU200E achieves 200 MHz CPU frequency using PLL configuration Ref. No. 10 from Table 18: PLL_CFG[0:4] = 10000, PCI_SYNC_IN = 33–66 MHz, memory bus = 75–100 MHz, CPU clock = 150–200 MHz, with PCI-to-Mem multiplier = 3 and Mem-to-CPU multiplier = 2. This configuration is explicitly validated for the 200 MHz variant and requires correct strapping of PLL_CFG pins during power-on reset.

Does XPC8240LZU200E support 5 V-tolerant PCI signaling?

Yes, XPC8240LZU200E supports 5 V-tolerant PCI signaling on LVDD input-tolerant pins (PCI interface, EPIC control, OSC_IN), with absolute maximum input voltage of 5.75 V when LVDD is connected to 5.0 V. This allows direct interfacing with standard 5 V PCI slots without level-shifting circuitry, maintaining full PCI Rev 2.2 compliance while simplifying board design.

What are the power supply sequencing requirements for XPC8240LZU200E?

XPC8240LZU200E requires strict voltage sequencing: VDD/AVDD/AVDD2/LAVDD (2.625 V) must stabilize before OVDD/GVDD (3.3 V), and LVDD (5.0 V or 3.3 V) must not exceed VDD by more than 5.4 V or OVDD by more than 3.6 V during power-up/down. Violating these limits-even briefly beyond the 20 ms allowance-risks latch-up or permanent damage. Sequencing controllers or discrete RC networks are recommended for robust startup.
