NXP Semiconductors MPC8275VRMIBA

Overview

MPC8275VRMIBA from NXP Semiconductors (formerly Freescale) is a PowerQUICC II integrated communications processor featuring a dual-issue G2_LE core, 32-bit RISC CPM, and integrated 10/100 Ethernet FCCs. It operates at up to 450 MHz core frequency, includes 16 KB instruction and 16 KB data caches, supports PCI bridge functionality, and targets telecom infrastructure, industrial gateways, and legacy protocol bridging applications.

For engineers reviewing the MPC8275VRMIBA datasheet, MPC8275VRMIBA pinout, MPC8275VRMIBA application, or MPC8275VRMIBA equivalent, key selection considerations include its 516-pin PBGA package, dual PLL architecture enabling independent core/CPM clocking, 3× FCCs with MII/RMII support, 4× SCCs for HDLC/UART/transparent protocols, and USB 2.0 full/low-speed controller - all validated for extended temperature operation (–40°C to +105°C junction).

Technical Context

The MPC8275VRMIBA integrates a Power Architecture-compliant G2_LE microprocessor core with separate 16 KB I-cache and D-cache, physically addressed and four-way set associative, alongside a dedicated 32-bit RISC Communications Processor Module (CPM) with 32 KB dual-port RAM/ROM. Its dual PLL system allows independent core and CPM clock domains - e.g., 450 MHz core with 200 MHz CPM - optimizing power/performance trade-offs in real-time communication workloads.

It implements three Fast Communication Controllers (FCCs) supporting 10/100-Mbit Ethernet via MII or RMII, two Multichannel Controllers (MCCs), four Serial Communications Controllers (SCCs) compatible with HDLC, UART, BISYNC, and transparent modes, plus one USB 2.0 controller with host/slave capability. The device lacks Security Engine (SEC) and TC/IMA layers present in MPC8280, confirming its role as a cost-optimized, non-ATM variant within the HiP7 PowerQUICC II family.

Key Specifications

Equivalent & Alternatives

The following parts are listed as comparable options for similar integrated communications processor applications.

Compared with MPC8270VR, MPC8275VRMIBA delivers identical package compatibility but adds UTOPIA II support and dual SI blocks for expanded TDM scalability; versus MPC8280VR, it omits TC/IMA to reduce cost and power while retaining full FCC/SCC/USB functionality for non-ATM edge nodes.

Manufacturer

NXP Semiconductors is a global semiconductor leader focused on secure connectivity solutions for automotive, industrial, and IoT markets, formed from the acquisition of Freescale Semiconductor in 2015.

The MPC8275VRMIBA belongs to the PowerQUICC II family - designed specifically for cost-sensitive, high-reliability communications processing in legacy telecom and industrial networking where integrated FCCs, SCCs, and PCI bridging eliminate external protocol ICs.

FAQ

What is the maximum operating junction temperature for the MPC8275VRMIBA?

The MPC8275VRMIBA has a maximum rated junction temperature of 105°C under recommended operating conditions. This value is specified in Table 4 of the MPC8280EC Rev. 2 datasheet, which applies to all HiP7 PowerQUICC II devices including MPC8275VRMIBA. Thermal design must ensure TJ does not exceed this limit during sustained operation, especially at 450 MHz core frequency with active FCC/SCC peripherals.

Does the MPC8275VRMIBA support USB 2.0 host mode with isochronous transfers?

Yes, the MPC8275VRMIBA USB controller supports host mode with control, bulk, interrupt, and isochronous data transfers. As documented in Section 1.1 Features of the MPC8280EC Rev. 2 datasheet, isochronous transfers are explicitly enabled in host mode, with CRC16 generation/checking, NRZI encoding/decoding, and flexible buffer allocation per frame - all implemented in hardware without CPU intervention.

Is the MPC8275VRMIBA pin-compatible with the MPC8280VR in the same 516-pin PBGA package?

Yes, the MPC8275VRMIBA and MPC8280VR share identical 516-pin PBGA (VR) mechanical packaging, ball map, and power/ground pin assignments. However, functional pin definitions differ for UTOPIA, TC layer, and IMA-related signals - these pins are reserved/no-connect on MPC8275VRMIBA per Table 1 and Figure 1 notes in the MPC8280EC datasheet.

What clock configuration options does the MPC8275VRMIBA support for its core and CPM subsystems?

The MPC8275VRMIBA supports independent PLL multipliers: core clock ratios of 2:1, 2.5:1, 3:1, 3.5:1, 4:1, 4.5:1, 5:1, 6:1, 7:1, or 8:1; and CPM clock ratios of 2:1, 2.5:1, 3:1, 3.5:1, 4:1, 5:1, 6:1, or 8:1. These are configured via SIUMCR register bits and enable optimized performance-per-watt partitioning - e.g., 450 MHz core with 200 MHz CPM - as verified in Table 7 power dissipation data.

Does the MPC8275VRMIBA include a security engine (SEC) for cryptographic acceleration?

No, the MPC8275VRMIBA does not include a Security Engine (SEC). Table 1 of the MPC8280EC Rev. 2 datasheet explicitly lists SEC support as "-" for MPC8270, MPC8275, and MPC8280 columns, confirming SEC is exclusive to later PowerQUICC III generations. Cryptographic functions must be implemented in software or via external co-processors when using MPC8275VRMIBA.
