KMPC8315VRAGDA Equivalent & Substitute Parts

Part Overview

The KMPC8315VRAGDA is a PowerPC e300c3 Microprocessor IC from the MPC83xx series, featuring a single 32-bit core operating at 400MHz in a 620-HBGA (29x29) package. This embedded processor integrates dual Gigabit Ethernet ports, dual SATA 3Gbps interfaces, USB 2.0 with PHY, and multiple serial communication protocols including DUART, I2C, PCI, SPI, and TDM. The device supports DDR and DDR2 memory controllers and operates across an industrial temperature range of 0°C to 105°C with multi-voltage I/O support (1.8V, 2.5V, 3.3V).

The KMPC8315VRAGDA is classified as obsolete, making equivalent substitute parts necessary for ongoing system support, maintenance, and new design implementations where this processor family remains applicable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KMPC8315VRAGDA is determined by strict equivalence across the following critical parameters:

Core Architecture & Performance: The processor must implement the PowerPC e300c3 instruction set with identical 1-core, 32-bit configuration and 400MHz clock speed to ensure binary compatibility with existing firmware and software stacks.

Memory Interface: DDR and DDR2 controller support is mandatory for system memory compatibility without redesign of memory subsystems.

Peripheral Integration: Dual Gigabit Ethernet (10/100/1000Mbps), dual SATA 3Gbps, and USB 2.0 with PHY must be present. Serial communication support for DUART, I2C, PCI, SPI, and TDM is required for legacy system integration.

Electrical Specifications: Multi-voltage I/O support (1.8V, 2.5V, 3.3V) and operating temperature range (0°C ~ 105°C) must be maintained.

Package & Form Factor: The 620-HBGA (29x29) surface-mount package is mandatory for PCB layout compatibility.

Parameter Comparison

Engineering Selection Recommendations

The MPC8315VRAGDA serves as a direct functional equivalent to the KMPC8315VRAGDA. Both devices share identical core architecture, performance specifications, peripheral integration, and package form factor. The primary distinction is product status: the KMPC8315VRAGDA is obsolete while the MPC8315VRAGDA maintains active production status.

For new designs or system maintenance requiring this processor family, the MPC8315VRAGDA is the appropriate selection due to its active availability and continued manufacturer support. The substitute part maintains full compatibility with existing firmware, software, and PCB designs developed for the KMPC8315VRAGDA.

Compliance considerations: The KMPC8315VRAGDA is documented as ROHS3 Compliant and REACH Unaffected. Compliance documentation for the MPC8315VRAGDA should be verified with the manufacturer for applications requiring specific regulatory certifications.

Frequently Asked Questions (FAQ)

Q: Are the KMPC8315VRAGDA and MPC8315VRAGDA pin-compatible?

A: Yes. Both devices use the 620-HBGA (29x29) package with identical pinout, enabling direct PCB substitution without layout modifications.

Q: Will existing firmware run on the MPC8315VRAGDA substitute?

A: Yes. Both processors implement the PowerPC e300c3 instruction set architecture with identical core configuration, clock speed, and peripheral interfaces, ensuring binary compatibility with existing software stacks.

Q: What is the difference between these two part numbers?

A: The KMPC8315VRAGDA (NXP USA Inc.) and MPC8315VRAGDA (Freescale Semiconductor) are functionally equivalent devices from the same MPC83xx product family. The difference reflects manufacturer designation and product lifecycle status. The KMPC8315VRAGDA is obsolete; the MPC8315VRAGDA is in active production.

Q: Can I use the MPC8315VRAGDA in a system originally designed for the KMPC8315VRAGDA?
