MPC755CPX400LER2

Overview

The MPC755CPX400LER2 is a PowerPC-based RISC microprocessor featuring an e600 core with a maximum clock frequency of 400 MHz. It utilizes a CBGA-360 package and operates at a core voltage of 2 V, supporting I/O voltages of 2.5 V and 3.3 V. The device includes 32 kB L1 instruction and data caches, alongside an internal L2 cache interface supporting up to 1 MB of external SRAM. Designed for low-power applications, it supports doze, nap, and sleep power management modes.

Feature Summary

• Implements the PowerPC instruction set architecture with out-of-order execution capabilities.
• Integrates an internal L2 cache controller and tags for external SRAM connectivity.
• Includes a thermal management assist unit with on-chip sensors for temperature regulation.
• Supports dynamic power management and multiple static low-power operating modes.

Applications

• Low-cost embedded systems requiring PowerPC compatibility
• Network infrastructure equipment
• Industrial control applications

Procurement Notes

Verify that the specific suffix 'R2' aligns with the manufacturer's current ordering documentation, as datasheets may list standard variants without this suffix. Confirm RoHS compliance status directly with NXP Semiconductors, as historical production data indicates potential non-compliance for older revisions. Ensure the CBGA-360 package availability matches your manufacturing requirements.

Selection Notes

Select this component when a PowerPC e600 core is required for legacy system compatibility or specific architectural features. Consider the CBGA-360 package constraints and the need for external L2 SRAM configuration. Evaluate thermal management needs due to the integrated TAU and verify that the 2 V core voltage supply is supported by the target system design.

Part Context

The MPC755 belongs to the Freescale/NXP MPC755 family of RISC microprocessors targeting low-power, cost-sensitive applications. It shares architectural similarities with the MPC745 but adds an internal L2 cache interface. This specific part number represents a 400 MHz variant within the broader MPC755 product line, designed for integration into complex embedded environments.

Replacement Considerations

Consult NXP sales offices for recommended upgrades, as the general MPC755 specification notes these devices are no longer in production. No direct public substitute part numbers are confirmed in the provided documentation.
