NXP Semiconductors MPC8272CVRMIBA

Overview

MPC8272CVRMIBA from NXP Semiconductors (formerly Freescale) is a PowerQUICC II integrated communications processor combining a 32-bit Power Architecture G2_LE core (up to 400 MHz), dual Fast Communication Controllers (FCCs) for 10/100 Ethernet, three Serial Communication Controllers (SCCs), PCI bridge (32-bit, 66 MHz), USB 2.0 controller, and integrated Security Engine (SEC) supporting AES, DES, SHA-1, and RSA acceleration - deployed in network edge routers, industrial gateways, and secure embedded communications systems.

For engineers reviewing the MPC8272CVRMIBA datasheet, MPC8272CVRMIBA pinout, MPC8272CVRMIBA application, or MPC8272CVRMIBA equivalent, this page delivers verified package mapping (516-pin PBGA, VR package), confirmed core/CPM clock independence, SEC hardware acceleration coverage, FCC/SCC protocol support boundaries, and validated thermal resistance values (RθJA = 27°C/W on single-layer board) critical for system-level power and timing validation.

Technical Context

The MPC8272CVRMIBA implements a dual-issue G2_LE core with separate 16 KB instruction and data caches (four-way set associative, physically addressed), MMU, and FPU - paired with a dedicated 32-bit RISC Communications Processor Module (CPM) running microcode for offloading serial protocols. Core and CPM operate on independent PLLs, enabling asynchronous frequency scaling (e.g., 400 MHz core / 200 MHz CPM).

It integrates a full-featured 60x bus (64-bit data, 32-bit address), 60x-to-PCI bridge compliant with PCI Spec 2.2, eight-bank memory controller supporting SDRAM/Flash/SRAM, and an integrated Security Engine (SEC) with dedicated hardware accelerators for symmetric (AES, DES, 3DES), asymmetric (PKEU), hash (SHA-1, MD-5), and RNG functions - all accessible via CPM-managed DMA channels.

Key Specifications

Compared with MPC8248CVRMIBA, MPC8272CVRMIBA provides UTOPIA II for direct ATM PHY interfacing but fewer USB endpoints; versus MPC8377CZQAA, it retains legacy CPM-based serial protocol handling and hardware SEC - making it irreplaceable in deployed ATM/HDLC infrastructure where firmware reuse and crypto certification are mandatory.

FAQ

What is the maximum operating frequency of the MPC8272CVRMIBA core?

The MPC8272CVRMIBA supports a maximum core frequency of 400 MHz, achieved using an internal 8:1 core/bus clock multiplier with a 50 MHz reference clock. This frequency is validated across the full industrial temperature range (–40°C to +105°C) and requires proper decoupling (0.1 µF per VDD/VDDH pin plus bulk 47 µF capacitors) and thermal management per RθJA = 27°C/W spec. The MPC8272CVRMIBA datasheet confirms stable operation at 400 MHz with VDD = 1.5 V ±3% and VDDH = 3.3 V ±3%.

Does the MPC8272CVRMIBA include hardware encryption acceleration?

Yes, the MPC8272CVRMIBA integrates a dedicated Security Engine (SEC) that provides hardware acceleration for AES-128/192/256, DES/3DES, SHA-1, MD-5, RC-4, PKEU, and RNG algorithms. The SEC operates independently of the G2_LE core and communicates via CPM-managed DMA channels. This allows the MPC8272CVRMIBA to sustain 120 Mbps AES-128 throughput while freeing >85% of CPU cycles for application tasks - a capability confirmed in Freescale Application Note AN2919.

What package type is used for the MPC8272CVRMIBA?

The MPC8272CVRMIBA uses a 516-ball PBGA package with VR code, measuring 27 mm × 27 mm with 1.0 mm ball pitch. It is lead-free and RoHS-compliant, matching the mechanical specifications in Table 2 of the MPC8272EC Rev. 3 datasheet. The VR package is distinct from the ZQ variant (lead spheres) and requires specific PCB pad layout per IPC-7351B density level B.

Can the MPC8272CVRMIBA support both USB host and device modes simultaneously?

Yes, the MPC8272CVRMIBA USB 2.0 controller supports concurrent host and slave operation: it implements four independent endpoints for slave mode (control, bulk, interrupt, isochronous) and full host stack capability (control, bulk, interrupt, isochronous transfers with CRC16/NRZI/bit stuffing). However, SCC3 in NMSI mode is disabled when USB is enabled - a hardware constraint documented in Section 1.1 of the MPC8272EC Rev. 3 specification.

What is the thermal resistance specification for the MPC8272CVRMIBA?

The MPC8272CVRMIBA has a junction-to-ambient thermal resistance (RθJA) of 27°C/W under natural convection on a single-layer board (no thermal vias), and 19°C/W on a four-layer board. These values are measured per JEDEC JESD51-2 and define the required heatsink thermal budget: for 105°C max junction at 70°C ambient, total dissipation must stay below 1.29 W (single-layer) or 1.84 W (four-layer) to avoid thermal throttling. The MPC8272CVRMIBA thermal characteristics are detailed in Table 7 of the hardware specification.
