NXP Semiconductors MPC8272VRMIBA

Overview

MPC8272VRMIBA from NXP Semiconductors (formerly Freescale) is a PowerQUICC II integrated communications processor combining a 32-bit Power Architecture G2_LE core (400 MHz max), dual Fast Communication Controllers (FCCs) for 10/100 Ethernet, three Serial Communication Controllers (SCCs), PCI bridge (32-bit, 66 MHz), and integrated Security Engine (SEC) supporting AES, DES, SHA-1, and RSA acceleration - deployed in carrier-grade edge routers and industrial protocol gateways.

For engineers reviewing the MPC8272VRMIBA datasheet, MPC8272VRMIBA pinout, MPC8272VRMIBA application, or MPC8272VRMIBA equivalent, key selection criteria include its dual-clock domain architecture (separate PLLs for CPU and CPM), 516-pin PBGA package with 1.5 V core / 3.3 V I/O supply separation, SEC hardware acceleration, and UTOPIA II interface support - all critical for deterministic real-time packet processing and secure embedded networking.

Technical Context

The MPC8272VRMIBA implements a dual-issue G2_LE core derived from the MPC603e, featuring separate 16 KB instruction and data caches (four-way set associative, physically addressed), MMU, and FPU. Its Communications Processor Module (CPM) operates independently via dual-port RAM and dedicated RISC microcontroller, enabling concurrent protocol offload for HDLC, UART, transparent serial, and TDM interfaces.

AC timing is defined across four bus speeds (66.67–133 MHz), with CPM outputs specified at 50% signal thresholds under 50 pF load (MAX) and 10 pF (MIN). The 60x bus supports burst transfers, multiple masters, and 64-bit data width, while the PCI bridge complies with PCI Specification 2.2 and supports hot-swap per PICMG 2.1.

FAQ

What is the maximum operating frequency of the MPC8272VRMIBA CPU core?

The MPC8272VRMIBA features a G2_LE core with a maximum rated frequency of 400 MHz, achieved using an internal clock multiplier ratio of 8:1 applied to a 50 MHz CLKIN source. This frequency is validated under recommended operating conditions (VDD = 1.5 V ±5%, TA ≤ 70°C) and requires adequate thermal management to maintain junction temperature below 105°C.

Does the MPC8272VRMIBA support hardware encryption acceleration?

Yes, the MPC8272VRMIBA includes a dedicated Security Engine (SEC) that accelerates AES-128/192/256, DES/3DES, SHA-1, MD-5, RC4, RNG, and PKEU operations in hardware. This enables full IPsec ESP/AH processing at line rate for 10/100 Ethernet without consuming G2_LE core cycles - a capability confirmed in the MPC8272EC Rev. 3 specification.

What package type and pin count does the MPC8272VRMIBA use?

The MPC8272VRMIBA uses a 516-ball plastic ball grid array (PBGA) package designated "VR", with lead-free finish and 1.27 mm ball pitch. It measures 27 mm × 27 mm and includes a thermal pad on the underside for PCB-level heat dissipation - matching the mechanical specifications in Table 2 of the MPC8272EC Rev. 3 datasheet.

Is the MPC8272VRMIBA pin-compatible with other PowerQUICC II devices like the MPC8248?

Yes, the MPC8272VRMIBA is pin-compatible with the MPC8248VRMIBA, MPC8271VRMIBA, and MPC8247VRMIBA within the same VR-package family. All share identical 516-ball PBGA layout, power sequencing, and signal assignments - allowing board reuse across variants differentiated by feature enablement (e.g., SEC presence, UTOPIA II).

What communication interfaces are supported by the MPC8272VRMIBA's CPM module?

The MPC8272VRMIBA's Communications Processor Module (CPM) supports three Serial Communication Controllers (SCCs) for HDLC, UART, transparent, and QUICC multichannel protocols; two Serial Management Controllers (SMCs); one SPI; one I²C; and two TDM interfaces. These are implemented via dedicated CPM pins (PA[8–31], PB[18–31], etc.) with configurable baud rate generators and virtual DMA channels.
