NXP Semiconductors KMPC8248CVRTIEA

Overview

KMPC8248CVRTIEA from Freescale Semiconductor is a PowerQUICC II integrated communications processor featuring a 32-bit Power Architecture® G2_LE core (266–400 MHz), dual 16 KB instruction/data caches, integrated security engine (SEC) supporting AES/DES/SHA-1/RNG, PCI bridge (32-bit, 66 MHz), two Fast Communication Controllers (FCCs) for 10/100 Ethernet, and three Serial Communications Controllers (SCCs). It targets secure network edge routers and industrial gateways requiring deterministic real-time packet processing.

For engineers reviewing the KMPC8248CVRTIEA datasheet, KMPC8248CVRTIEA pinout, KMPC8248CVRTIEA application, or KMPC8248CVRTIEA equivalent, key selection criteria include SEC hardware acceleration support, VR-package 516-pin PBGA compatibility, 1.5 V core / 3.3 V I/O supply separation, dual PLL clocking architecture, and UTOPIA II interface capability (MPC8272/8248 only).

Technical Context

The KMPC8248CVRTIEA integrates a dual-issue G2_LE core with MMU and separate 16 KB I/D caches, a modified Communications Processor Module (CPM) with 16 KB dual-port RAM and 4 KB instruction RAM, and a dedicated Security Engine (SEC) supporting DES, 3DES, AES, SHA-1, MD-5, RC-4, PKEU, and RNG in hardware. It implements a 64-bit 60x bus with up to 66 MHz operation and supports burst/single transfers across 64/32/16/8-bit port sizes.

Its clock system uses independent PLLs for core and CPM domains, enabling frequency ratios of 2:1 to 8:1 (core/bus) and 2:1 to 8:1 (CPM/bus); it includes a 60x-to-PCI bridge compliant with PCI Spec 2.2 (32-bit, 66 MHz, 3.3 V), four DMA channels, and IEEE 1149.1 JTAG test access. The device operates within 0–70°C ambient and 105°C junction temperature limits under 1.425–1.575 V core and 3.135–3.465 V I/O supply conditions.

FAQ

What is the maximum operating frequency of the KMPC8248CVRTIEA CPU core?

The KMPC8248CVRTIEA CPU core operates at 266–400 MHz, with the exact frequency determined by the external CLKIN signal and PLLCFG pin configuration at reset. At 400 MHz, the G2_LE core delivers approximately 700 MIPS performance while maintaining full cache coherency and MMU support - verified in Freescale's MPC8272EC Rev. 3 specification under Section 1.1 Features.

Does KMPC8248CVRTIEA support hardware-accelerated encryption, and which algorithms are implemented?

Yes, KMPC8248CVRTIEA includes a dedicated Security Engine (SEC) supporting DES, 3DES, AES (128/192/256-bit), SHA-1, MD-5, RC-4, PKEU, and RNG in hardware - confirmed in Table 1 and Figure 1 notes of the MPC8272EC Rev. 3 document. This SEC is exclusive to MPC8272 and MPC8248 variants, not present in MPC8271/MPC8247.

What package type and pin count does KMPC8248CVRTIEA use?

KMPC8248CVRTIEA uses a 516-ball PBGA package with VR designation (lead-free), as specified in Table 2 of the MPC8272EC Rev. 3 document. This package has 27 mm × 27 mm body size, 1.0 mm ball pitch, and thermal balls arranged for PCB-level heat conduction - identical to MPC8272VR and MPC8247VR footprints.

Can KMPC8248CVRTIEA be used as a drop-in replacement for MPC8272VR in existing designs?

Yes, KMPC8248CVRTIEA is functionally and pin-compatible with MPC8272VR - sharing identical VR-package 516 PBGA footprint, electrical characteristics, thermal profile, and feature set including SEC, FCCs, SCCs, and PCI bridge. Freescale explicitly groups both devices under "MPC8272 family" in the hardware spec, confirming interchangeability without layout or firmware modification.

What are the supported I/O voltage levels and power supply requirements for KMPC8248CVRTIEA?

KMPC8248CVRTIEA requires two independent supplies: 1.425–1.575 V for core logic (VDD/VCCSYN) and 3.135–3.465 V for I/O (VDDH), per Table 4 of MPC8272EC Rev. 3. Input high voltage (VIH) is 2.0–3.465 V; output low voltage (VOL) is ≤0.4 V at 6 mA drive strength - ensuring compatibility with standard 3.3 V LVTTL peripherals.
