NXP Semiconductors XPC8240RVV250E

Overview

XPC8240RVV250E from Freescale Semiconductor is a 250 MHz integrated PowerPC processor with MPC603e core, dual PLL architecture (CPU and peripheral/memory bus), 2.625 V ±125 mV core supply, and TBGA package optimized for embedded control in PCI-based industrial systems requiring deterministic real-time response and memory coherency.

For engineers reviewing the XPC8240RVV250E datasheet, XPC8240RVV250E pinout, XPC8240RVV250E application, or XPC8240RVV250E equivalent, this part supports 66 MHz PCI bus operation, 100 MHz memory bus, and 250 MHz CPU clock via configurable PLL_CFG[0:4] inputs - critical for legacy PCI-to-embedded bridge designs, telecom line cards, and industrial automation controllers where voltage tolerance, thermal range (0–105°C), and power management modes (Doze/Nap/Sleep) are design-critical.

Technical Context

The XPC8240RVV250E implements two independent PLLs: one for CPU clock generation (memory-to-CPU multiplier up to 4×) and another for peripheral/memory bus clocking (PCI-to-memory multiplier up to 3×), both configured via five-pin PLL_CFG[0:4] strap inputs. It retains full MPC8240 instruction set compatibility and integrates EPIC (Embedded Performance Interface Controller) for PCI host bridge functionality.

It operates within a die-junction temperature range of 0–105°C and requires four distinct supply domains: VDD/AVDD/AVDD2/LAVDD at 2.625 V ±5%, OVDD at 3.3 V ±0.3 V, GVDD at 3.3 V ±5%, and LVDD at either 3.3 V or 5.0 V ±5%. LVDD-tolerant inputs include PCI interface, EPIC control, and OSC_IN signals.

Manufacturer

Freescale Semiconductor (now part of NXP Semiconductors) was a leading designer of embedded processors and analog/mixed-signal ICs, specializing in automotive, industrial, and networking solutions before its 2015 acquisition.

The XPC8240RVV250E belongs to the MPC824x family of integrated PCI host processors targeting cost-sensitive, thermally constrained embedded systems needing deterministic real-time performance without external bridge logic.

FAQ

What is the maximum guaranteed CPU frequency for XPC8240RVV250E?

The XPC8240RVV250E is characterized and tested for guaranteed operation at 250 MHz CPU frequency under all recommended operating conditions - including 2.625 V ±125 mV core supply and 0–105°C junction temperature. This frequency is fixed by mask option and cannot be overclocked; higher frequencies require different part numbers such as XPC8240RZU250E (same spec, alternate marking).

Does XPC8240RVV250E support PCI 66 MHz operation?

Yes, XPC8240RVV250E supports 66 MHz PCI bus operation as confirmed in Table 18 (Ref. No. E, C, 1C, 1D) with valid PLL_CFG[0:4] configurations. The device meets PCI v2.2 electrical specifications when OVDD = 3.3 V ±0.3 V and LVDD = 3.3 V or 5.0 V ±5%, and requires proper termination and trace length matching per Freescale's MPC8240RZUPNS layout guidelines.

What power management modes does XPC8240RVV250E support?

XPC8240RVV250E supports three hardware-initiated power saving modes: Doze (2.6 W typical), Nap (900 mW), and Sleep (500 mW). These are entered via EPIC register writes and reduce dynamic power by gating clocks to non-essential blocks while preserving register and cache state - enabling rapid wake-up (<1 µs) without software reinitialization. All modes are validated across the full 0–105°C range.

Is XPC8240RVV250E pin-compatible with other MPC8240 variants?

No, XPC8240RVV250E is not pin-compatible with standard MPC8240RZU250E or MPC8245 parts due to differences in supply pin allocation and thermal pad configuration. While both use 324-pin TBGA packages, the VDD/AVDD/AVDD2/LAVDD pin assignments and decoupling requirements differ per revision - PCB layout must follow Freescale's XPC8240RVV250E-specific mechanical drawing and power sequencing diagram.

What does the 'X' prefix signify in XPC8240RVV250E?

The 'X' prefix in XPC8240RVV250E indicates a pilot production prototype per Freescale SOP 3-13 - meaning it is a limited-volume release with preliminary reliability data, subject to change before final qualification. Customers must obtain written authorization acknowledging this status prior to integration; design-in should include margin for potential spec revisions or mask changes affecting timing or power behavior.
