MPC603RRX300LC

Overview

The MPC603RRX300LC is a PowerPC 603e RISC microprocessor manufactured by Motorola, now archived by Freescale Semiconductor. It operates at a CPU frequency of 300 MHz with a supply voltage of 2.5 V ±5%. The device supports an operating junction temperature range from 0°C to 105°C. It utilizes a CBGA package type and corresponds to the PID7v-603e (Goldeneye) specification revision 2.1.

Feature Summary

• Implements the PowerPC 603e RISC architecture for high-performance processing
• Supports hardware and software coherency mechanisms for multi-processor systems
• Includes integrated cache management instructions such as dcbi and dcbz

Applications

• Multi-processor embedded systems requiring hardware/software coherency
• Industrial control applications within commercial temperature ranges
• Systems utilizing bus address pipelining and reservation logic

Procurement Notes

This component is archived and no longer in active production. Verify availability through authorized distributors or surplus channels. Confirm that the specific revision matches system requirements regarding known errata, particularly concerning cache coherency and bus arbitration behaviors documented in the datasheet.

Selection Notes

Select this processor for legacy designs requiring the PowerPC 603e core at 300 MHz. Ensure the design accommodates the specified 2.5V power supply and CBGA packaging constraints. Review the errata section for potential workarounds related to snoop copybacks and touch loads if implementing complex multi-processor coherence protocols.

Part Context

The MPC603R series belongs to the PowerPC 603e family, specifically the Goldeneye variant. This part number represents a manufacturing improvement revision over previous versions without functional changes. It is distinct from the MPE603R series which does not guarantee floating-point performance.

Replacement Considerations

No direct public substitutes are listed. Consider reviewing other PowerPC 603e variants like the MPC603RRX266LC for lower frequency needs, though these remain obsolete.
