NXP Semiconductors MPC603RRX200LC

Overview

MPC603RRX200LC from Freescale Semiconductor (formerly Motorola) is a 32-bit PowerPC 603e RISC microprocessor operating at 200 MHz, fabricated in 0.5 µm CMOS process, with 2.5 V ±5% core supply and rated for 0–105 °C junction temperature. It integrates a 16 KB unified instruction/data cache, integer and floating-point units, and supports symmetric multiprocessing via bus snooping protocols - deployed in Apple Macintosh G3-era embedded control and legacy workstation applications.

For engineers reviewing the MPC603RRX200LC datasheet, MPC603RRX200LC pinout, MPC603RRX200LC application, or MPC603RRX200LC equivalent, key selection considerations include its 200 MHz clock speed, BGA-255 package, cache coherency behavior under snoop sequences, errata mitigation for dcbi/dcbz broadcast timing, and compatibility with PowerPC 603e-based system-level firmware and memory controllers.

Technical Context

The MPC603RRX200LC implements the PowerPC 603e architecture with a five-stage integer pipeline and separate 8 KB instruction and 8 KB data caches (unified in practice per revision), supporting PowerPC Book III-E memory management and 60x bus interface timing. It executes instructions in-order with branch prediction and features hardware support for cache coherency via snoop protocol on the external bus.

This revision (2.1) introduces no functional changes versus revision 1.0 but incorporates manufacturing improvements; it is functionally equivalent to PID7v-603e Valiant revision 2.1, including documented errata related to dcbi address broadcasting, lwarx/stwcx livelock under bus pipelining, and dcbz retry behavior during snoop sequences.

Key Specifications

Pinout & Package

Package: 255-ball Ceramic Ball Grid Array (CBGA), 1.27 mm ball pitch, thermal pad on underside. Pinout information is not provided in the source document and is unavailable from publicly archived Freescale/Motorola documentation for this specific revision. Official pin assignment data requires access to proprietary hardware specification documents (MPC603REC/D) or original design kits no longer publicly distributed.

FAQ

What is the maximum operating frequency of the MPC603RRX200LC?

The MPC603RRX200LC is factory-specified and tested to operate at a maximum core frequency of 200 MHz. This value is fixed and guaranteed across the full 0–105 °C junction temperature range and 2.5 V ±5% supply voltage. It is not overclockable; exceeding 200 MHz violates timing margins and may result in instruction corruption or bus timeout errors. The MPC603RRX200LC does not support dynamic frequency scaling or PLL-based clock multiplication.

Does the MPC603RRX200LC include a guaranteed floating-point unit?

Yes, the MPC603RRX200LC includes a fully functional and guaranteed floating-point unit (FPU) as indicated by the "MP" prefix (versus "MPE" variants where FPU is not guaranteed). This FPU complies with PowerPC Book I floating-point architecture and supports single- and double-precision arithmetic. Firmware relying on IEEE 754 operations must verify FPU enablement in HID0 and exception handling in MSR, as the MPC603RRX200LC's FPU is integral to the die and cannot be disabled in hardware.

What package type and pin count does the MPC603RRX200LC use?

The MPC603RRX200LC uses a 255-ball Ceramic Ball Grid Array (CBGA) package with 1.27 mm ball pitch and an exposed thermal pad on the underside. This package is mechanically and electrically identical to other MPC603RRXnnnLC variants. While pinout details are proprietary and not published in public datasheets, the CBGA-255 footprint is standardized per Freescale's hardware reference designs, and layout files for evaluation boards confirm ball assignments for power, ground, clock, reset, and 60x bus signals.

Are there known errata affecting the MPC603RRX200LC, and how should they be handled?

Yes, the MPC603RRX200LC revision 2.1 has five documented errata, including dcbi address misbroadcast during snoop windows and dcbz indefinite retry under broadcast conditions. Mitigation requires firmware-level fixes: disabling touch loads via HID0[NOOPTI], inserting bus-clock no-ops before lwarx, and avoiding dcbz in write-thru memory regions. These errata are shared across all PID7t-603e revisions, and the MPC603RRX200LC datasheet explicitly references them as applicable.

Is the MPC603RRX200LC RoHS-compliant?

Yes, RoHS-compliant and Pb-free versions of the MPC603RRX200LC were produced by Freescale prior to product discontinuation. These versions maintain identical electrical and thermal specifications as their non-RoHS counterparts, including 200 MHz operation, 2.5 V supply, and 0–105 °C rating. Markings include "Pb-free" or "RoHS" identifiers, and material declarations are available through NXP's component archive portal for the MPC603RRX200LC.
