NXP Semiconductors MPC8248VRPIEA

Overview

MPC8248VRPIEA 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 MPC8248VRPIEA datasheet, MPC8248VRPIEA pinout, MPC8248VRPIEA application, or MPC8248VRPIEA equivalent, key selection criteria include its dual-clock domain architecture (separate PLLs for CPU and CPM), 516-pin PBGA VR package with 1.5 V core / 3.3 V I/O supply separation, SEC hardware acceleration capability, and PCI-to-60x bridge configurability for legacy bus integration.

Technical Context

The MPC8248VRPIEA implements a dual-issue G2_LE core derived from the MPC603e microarchitecture, featuring separate 16 KB instruction and 16 KB data caches (four-way set associative, physically addressed), MMU support, and floating-point unit - all operating at up to 400 MHz via programmable core/bus clock multipliers (ratios 2:1 to 8:1). Its Communications Processor Module (CPM) runs independently at configurable frequencies (multipliers 2:1 to 8:1), managing serial peripherals via dedicated RISC microcontroller and 16 KB dual-port RAM.

Hardware security is delivered through the integrated Security Engine (SEC), which offloads cryptographic operations including AES-128/192/256, DES/3DES, SHA-1, MD-5, RC-4, PKEU, and RNG - eliminating software-only bottlenecks in IPsec, SSL/TLS, and secure boot implementations. The 60x bus interface supports 64-bit data width, burst transfers, and multiple master arbitration, while the PCI bridge complies with PCI Specification 2.2 and enables streaming DMA between PCI and on-chip memory.

Equivalent & Alternatives

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

Compared with MPC8272VRPIEA, MPC8248VRPIEA removes UTOPIA II but retains identical SEC, FCC, SCC, and PCI capabilities - making it optimal for non-ATM secure gateways. Versus MPC8313EVRAGDB, it offers proven SEC acceleration and legacy bus compatibility at lower power, though with older memory interface and lower peak frequency.

FAQ

What is the maximum operating frequency of the MPC8248VRPIEA CPU core?

The MPC8248VRPIEA CPU core operates at up to 400 MHz, achieved via its programmable internal core/bus clock multiplier (supporting ratios from 2:1 to 8:1) driven by a 33–100 MHz CLKIN reference. This frequency is confirmed in Section 1.1 "Features" and Table 8 "Estimated Power Dissipation", where 400 MHz is explicitly listed as a supported configuration under 100 MHz bus and 4× CPU multiplication factor. The MPC8248VRPIEA maintains full functionality - including SEC, FCC, and PCI - at this maximum rate.

Does the MPC8248VRPIEA include a hardware security engine, and what algorithms does it support?

Yes, the MPC8248VRPIEA includes an integrated Security Engine (SEC) - a dedicated hardware accelerator supporting AES (128/192/256-bit), DES/3DES, SHA-1, MD-5, RC-4, PKEU (public-key), and RNG (random number generation). This is explicitly stated in Table 1 ("Security engine (SEC): Yes" for MPC8248), Figure 1 block diagram (labeled "16 KB Security (SEC)"), and Section 1.1 "Features". The SEC operates independently of the G2_LE core, enabling concurrent crypto processing without CPU overhead.

What package type and pin count does the MPC8248VRPIEA use?

The MPC8248VRPIEA uses a 516-ball Plastic Ball Grid Array (PBGA) package in the VR variant - lead-free and RoHS-compliant, with a 27 mm × 27 mm body and 1.27 mm ball pitch. This is confirmed in Table 2 "MPC8272 PowerQUICC II Device Packages", which lists "MPC8248VR" under the VR (516 PBGA-Lead free) code, and in Section 9 "Package Description". The VR package is distinct from the ZQ variant (lead spheres) and is the standard industrial-grade option.

How does the MPC8248VRPIEA handle power supply separation, and why is it important?

The MPC8248VRPIEA mandates strict separation of 1.425–1.575 V core supply (VDD), 3.135–3.465 V I/O supply (VDDH), and dedicated 1.425–1.575 V PLL supply (VCCSYN). This is specified in Table 4 "Recommended Operating Conditions" and Section 4.6 "Layout Practices". Separation prevents noise coupling - especially critical because the PLL supply is highly sensitive, and I/O switching transients could destabilize core clocks. Each supply requires localized 0.1 µF ceramic + 47 µF bulk capacitors, as failure to isolate VDD/VDDH causes timing violations or SEC functional failure.

Is the MPC8248VRPIEA pin-compatible with other PowerQUICC II devices like the MPC8272?

The MPC8248VRPIEA is pin-compatible with the MPC8272VRPIEA in the same VR package - sharing identical 516-ball PBGA layout, power pin distribution, and signal ball assignments per Section 8 "Pinout" and Table 2. However, functional differences exist: MPC8272 includes UTOPIA II interface (absent in MPC8248), while both share SEC, FCC, SCC, PCI, and USB. Thus, MPC8248VRPIEA can replace MPC8272VRPIEA in designs not using UTOPIA II, but not vice versa without hardware modification.
