KMPC8358VRAGDDA Equivalent & Substitute Parts

Part Overview

The KMPC8358VRAGDDA is a PowerPC e300 microprocessor from the MPC83xx series manufactured by NXP USA Inc. This embedded processor operates at 400MHz with a single 32-bit core and integrates communications interfaces including QUICC Engine, Ethernet (10/100/1000Mbps), USB 1.x, and multiple serial protocols (UART, DUART, HDLC, SPI, I2C). The device is mounted as a 668-PBGA surface mount package with 29x29mm dimensions and supports DDR/DDR2 memory controllers.

The KMPC8358VRAGDDA is classified as obsolete. Locating equivalent or substitute components is necessary for legacy system maintenance, board redesigns, or when original inventory becomes unavailable.

Substitute Part Grouping Explanation

Substitution eligibility for the KMPC8358VRAGDDA is determined by the following core parameters:

• Processor Architecture: PowerPC e300 core
• Clock Speed: 400MHz operation
• Core Configuration: Single 32-bit core
• Memory Support: DDR and DDR2 controllers
• Peripheral Integration: Communications interfaces (QUICC Engine, Ethernet, USB, UART variants, I2C, SPI, PCI)
• Electrical Compatibility: I/O voltage levels (1.8V, 2.5V, 3.3V)
• Thermal Range: 0°C to 105°C operating temperature

The substitute part MPC8358VRAGDDA maintains functional equivalence across all critical processor specifications. Both parts share identical core architecture, clock frequency, memory controller support, and peripheral feature sets. Differences exist in package form factor (668-PBGA versus 740-TBGA), security feature implementation, and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the KMPC8358VRAGDDA and MPC8358VRAGDDA are classified as obsolete products. Selection between these parts must account for the following factors:

Regulatory Compliance: The KMPC8358VRAGDDA maintains ROHS3 compliance, while the MPC8358VRAGDDA is RoHS non-compliant. For applications subject to RoHS directives or environmental regulations, the KMPC8358VRAGDDA is the appropriate choice.

Package Footprint: The KMPC8358VRAGDDA uses a 668-PBGA package (29x29mm), while the MPC8358VRAGDDA uses a 740-TBGA package (37.5x37.5mm). PCB layout compatibility and available board space determine which package is suitable for a given application.

Security Features: The MPC8358VRAGDDA includes integrated cryptography and random number generator functionality. Applications requiring hardware-based security should specify the MPC8358VRAGDDA variant.

Functional Equivalence: Both parts provide identical processor performance, memory controller support, and peripheral integration. Core processor selection should prioritize package compatibility and regulatory requirements over functional differences.

Frequently Asked Questions (FAQ)

Q: Are KMPC8358VRAGDDA and MPC8358VRAGDDA functionally equivalent?

A: Both parts share the same PowerPC e300 core architecture, 400MHz clock speed, single 32-bit configuration, and peripheral feature set (QUICC Engine, Ethernet, USB, UART variants, I2C, SPI, PCI). The MPC8358VRAGDDA includes additional security co-processors. Functional equivalence is confirmed for standard embedded processing applications.

Q: What is the primary difference between these two parts?

A: The main differences are package form factor (668-PBGA versus 740-TBGA), security feature availability, and regulatory compliance status. The KMPC8358VRAGDDA is ROHS3 compliant; the MPC8358VRAGDDA is not.

Q: Can I substitute MPC8358VRAGDDA for KMPC8358VRAGDDA on an existing PCB?

A: Direct PCB substitution is not possible due to different package dimensions and pin configurations. The 668-PBGA (29x29mm) and 740-TBGA (37.5x37.5mm) packages have different footprints. PCB redesign is required for package migration.

Q: Which part should I select for a new design?

A: Both parts are obsolete. For new designs, alternative current-generation MPC83xx variants or successor processor families should be evaluated. If legacy compatibility is mandatory, package requirements and regulatory compliance determine the appropriate selection.

Q: Does the MPC8358VRAGDDA security feature set affect compatibility?

A: The integrated cryptography and random number generator in the MPC8358VRAGDDA do not affect functional compatibility with applications designed for the standard KMPC8358VRAGDDA. Applications not utilizing security features operate identically on both parts.

Q: What are the memory controller specifications for both parts?

A: Both the KMPC8358VRAGDDA and MPC8358VRAGDDA support DDR and DDR2 memory controllers with identical specifications and operating parameters.
