MPC755BRX350LE

Overview

The MPC755BRX350LE is a PowerPC-based RISC microprocessor manufactured by NXP Semiconductors. It implements the e600 core architecture with a single processing core and a 32-bit data bus width. The device operates at a maximum clock frequency of 350 MHz and utilizes a CBGA-360 package for surface mount installation. It supports L1 instruction and data caches of 32 kB each, alongside L2 cache options of 256 kB, 512 kB, or 1 MB. The processor functions within a voltage range of 2 V and operates reliably between -40°C and +105°C.

Feature Summary

• Implements the PowerPC instruction set architecture with an e600 core.
• Includes internal L2 tag combined with a dedicated L2 cache interface.
• Supports doze, nap, sleep, and dynamic power management modes.
• Features integrated thermal management assist unit with on-chip sensor.

Applications

• Low-cost embedded systems
• Low-power computing applications
• Systems requiring dynamic power management

Procurement Notes

Verify component authenticity through official manufacturer channels. Confirm that the specific part number matches the required specifications before integration. Check for any relevant errata or hardware specification addendums that may apply to this revision. Ensure compatibility with existing system voltage requirements and thermal constraints during the design phase.

Selection Notes

Select this component for designs requiring a PowerPC-compatible RISC processor with integrated L2 cache support. Consider the CBGA-360 package constraints for PCB layout. Evaluate power consumption profiles across different operating modes to ensure thermal limits are respected. Verify that the 350 MHz frequency meets the performance requirements of the target application.

Part Context

The MPC755 belongs to the MPC755 family of microprocessors designed for low-cost and low-power environments. It shares architectural similarities with the MPC745 but includes additional L2 cache interface capabilities not present in the latter. This series targets applications where efficient power management and reliable processing are critical.

Replacement Considerations

Consult official documentation for recommended upgrades as these devices are no longer in production. Contact the manufacturer's sales office for suitable replacement devices or alternative solutions compatible with the current design requirements.
