MPC755CRX400LE

The MPC755CRX400LE is a single-core PowerPC RISC microprocessor running at 400 MHz in a 360-CBGA (25×25) package. It targets low-cost, low-power embedded systems and integrates key processor and system interfaces to support compact, surface-mount designs.

Designed with consumer qualification and RoHS compliance, the MPC755CRX400LE combines a 32-bit PowerPC core with on-chip cache and L2 support, power-management features and system debug facilities to simplify embedded system integration.

Key Features

• Core  PowerPC 32-bit single core running at 400 MHz, optimized for RISC execution and embedded workloads.
• Cache and Memory  Integrated processor with 32-Kbyte instruction cache and 32-Kbyte data cache plus an internal L2 tag and a dedicated L2 cache interface (MPC755 family), providing streamlined on-chip caching and L2 support.
• System Bus  60x bus interface for external system connectivity and memory access (per MPC755 family hardware specifications).
• Power and Thermal Management  On-chip power-management modes including doze, nap, sleep and dynamic power management; documented thermal and power management features help manage system-level energy use.
• Debug and System Facilities  JTAG/COP interface, time base counter/decrementer, clock multiplier and performance monitor support system bring-up, debugging and performance analysis.
• Package and Mounting  360-CBGA (25×25) package, surface-mount mounting type; package case identified as 360-BCBGA/FCCBGA in documentation.
• Operating Range  Consumer qualification with an operating temperature range of 0°C to 105°C.
• Environmental Compliance  RoHS compliant to support regulatory and assembly requirements.

Typical Applications

• Low-cost embedded controllers  Suited to compact consumer and embedded applications that require a 32-bit PowerPC core with on-chip cache and L2 support.
• Energy-conscious designs  Systems that benefit from multiple power-management states (doze, nap, sleep, dynamic management) to reduce run-time power consumption.
• Compact, surface-mount systems  Designs requiring a high-density BGA package (360-CBGA, 25×25) for board-level space efficiency and robust mounting.

Unique Advantages

• PowerPC RISC architecture: A 32-bit PowerPC core delivering deterministic RISC execution for embedded software and legacy PowerPC codebases.
• Integrated cache and L2 interface: On-chip 32-Kbyte I and D caches plus L2 tags with a dedicated L2 interface reduce external memory bandwidth pressure and simplify cache hierarchy design.
• System-focused peripherals: Built-in debug (JTAG/COP), time base/decrementer and performance monitoring facilities accelerate bring-up and system validation.
• Flexible power management: Multiple power states (doze/nap/sleep and dynamic power management) support designs that need to balance performance and energy efficiency.
• Compact package: 360-CBGA (25×25) surface-mount package enables high-density board layouts while maintaining secure soldered attachment.
• Regulatory readiness: RoHS compliance helps address environmental and assembly process requirements for consumer-grade products.
