NXP Semiconductors KMPC8272VRTIEA

Overview

KMPC8272VRTIEA from NXP Semiconductors (formerly Freescale) is a PowerQUICC II integrated communications processor combining a 32-bit Power Architecture G2_LE core, dual Fast Communication Controllers (FCCs), three Serial Communication Controllers (SCCs), PCI bridge, USB 2.0 controller, and integrated Security Engine (SEC). It operates at up to 400 MHz, features 16 KB instruction and 16 KB data caches, supports 10/100 Ethernet via MII/RMII, and targets secure network edge devices requiring deterministic real-time processing.

For engineers reviewing the KMPC8272VRTIEA datasheet, KMPC8272VRTIEA pinout, KMPC8272VRTIEA application, or KMPC8272VRTIEA equivalent, this page delivers verified electrical specs, thermal limits, clock configuration modes, package mapping to 516-pin PBGA (VR), and functional distinctions versus MPC8248/MPC8271 - all critical for board-level integration, power budgeting, and cryptographic subsystem design.

Technical Context

The KMPC8272VRTIEA integrates a dual-issue G2_LE core with separate 16 KB I-cache and D-cache, MMU, and FPU, coupled to a dedicated Communications Processor Module (CPM) running independently at configurable frequencies via its own PLL. Its CPM includes 16 KB dual-port RAM and 4 KB instruction RAM for offloading serial protocol handling including HDLC, UART, and transparent modes.

It embeds a hardware Security Engine supporting AES, DES/3DES, SHA-1, MD-5, RC-4, PKEU, and RNG - exclusive to MPC8272/MPC8248 variants - and implements a 64-bit 60x bus with 32-bit address space, 60x-to-PCI bridge compliant with PCI Spec 2.2 (66 MHz, 3.3 V), and UTOPIA II interface (8-bit, 31 MHz) for ATM SAR support.

FAQ

What is the maximum operating frequency of the KMPC8272VRTIEA core?

The KMPC8272VRTIEA supports a maximum core frequency of 400 MHz, achieved using an internal clock multiplier ratio of 8:1 with a 50 MHz reference clock. This frequency is validated under recommended operating conditions (VDD = 1.425–1.575 V, TA = 0–70°C, TJ ≤ 105°C) and enables high-throughput packet processing for dual 10/100 Ethernet interfaces. The KMPC8272VRTIEA datasheet specifies AC timing parameters for 266 MHz, 300 MHz, and 400 MHz configurations.

Does the KMPC8272VRTIEA include a hardware security engine?

Yes, the KMPC8272VRTIEA includes a dedicated Security Engine (SEC) supporting AES, DES/3DES, SHA-1, MD-5, RC-4, PKEU, and RNG algorithms in hardware. This SEC is shared only with the MPC8248 variant and is absent in MPC8271/MPC8247. The KMPC8272VRTIEA uses this engine to accelerate cryptographic operations, enabling wire-speed IPsec and SSL/TLS offload without burdening the G2_LE core.

What package type and pin count does the KMPC8272VRTIEA use?

The KMPC8272VRTIEA uses a 516-ball plastic ball grid array (PBGA) package with lead-free finish, designated by the "VR" code. It measures 27 mm × 27 mm with 1.7 mm body height and follows JEDEC MO-205 standard. This package is identical across all PowerQUICC II VR variants (MPC8272VR, MPC8248VR, etc.) and supports standard SMT reflow profiles for high-volume manufacturing.

Can the KMPC8272VRTIEA support UTOPIA II interface for ATM applications?

Yes, the KMPC8272VRTIEA provides a full 8-bit UTOPIA II interface operating at 31 MHz, supporting ATM SAR at 155 Mbps with AAL0–AAL5 protocols, CBR/VBR/UBR/ABR traffic types, and up to 64K external connections. This capability is exclusive to KMPC8272VRTIEA and MPC8271VRTIEA within the family - MPC8248 and MPC8247 omit UTOPIA II entirely.

What are the key power supply requirements for the KMPC8272VRTIEA?

The KMPC8272VRTIEA requires two independent supplies: 1.425–1.575 V (VDD) for the core and PLLs, and 3.135–3.465 V (VDDH) for I/O. Each supply must be heavily decoupled with 0.1 µF capacitors per pin plus bulk 47 µF capacitors per supply domain. Layout mandates low-impedance paths to dedicated power/ground planes and strict noise control on VCCSYN (PLL supply) to prevent clock jitter.
