Overview
KMPC8248VRTIEA from NXP Semiconductors (formerly Freescale) is a PowerQUICC II integrated communications processor featuring 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, supports 10/100 Ethernet via MII/RMII, and delivers hardware-accelerated DES, 3DES, AES, SHA-1, and MD-5 encryption - deployed in secure network gateways and industrial protocol converters.
For engineers reviewing the KMPC8248VRTIEA datasheet, KMPC8248VRTIEA pinout, KMPC8248VRTIEA application, or KMPC8248VRTIEA equivalent, this page provides verified technical context, validated package mapping, confirmed pin functions, real-world timing constraints, and two rigorously cross-referenced alternative parts for embedded communications SoC selection.
Technical Context
The KMPC8248VRTIEA integrates a dual-issue G2_LE core with separate 16 KB instruction and data caches, MMU, and FPU, running at 266–400 MHz using programmable PLL multipliers (2:1 to 8:1 for core, 2:1 to 8:1 for CPM). Its communications subsystem includes two FCCs supporting IEEE 802.3 10/100 Ethernet and HDLC, three SCCs compatible with UART, HDLC, and QUICC multichannel protocols, and a dedicated SEC engine handling AES-128/192/256, DES, 3DES, SHA-1, and MD-5 in hardware.
It features a 64-bit 60x bus (up to 133 MHz), 32-bit 66 MHz PCI 2.2-compliant bridge with four DMA channels, eight-bank memory controller supporting SDRAM/Flash/SRAM, and dual 3.3 V I/O / 1.5 V core power domains. The device uses a 516-pin PBGA (VR package) with lead-free finish and is rated for 0–70 °C ambient operation with 105 °C max junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | G2_LE Power Architecture® microprocessor - fully compliant with Power ISA v2.02, enabling legacy MPC603e software compatibility and deterministic real-time execution. |
| Max Core Frequency | 400 MHz - achieved via 8:1 internal PLL multiplier on 50 MHz CLKIN; enables high-throughput packet processing in routing/firewall applications. |
| Integrated Security Engine | Hardware SEC supporting AES-128/192/256, DES, 3DES, SHA-1, MD-5, RC4, PKEU, RNG - offloads crypto operations from main CPU, reducing latency and CPU utilization by >70% in IPsec stacks. |
| Communication Peripherals | 2× FCCs (10/100 Ethernet + HDLC), 3× SCCs (UART/HDLC/SDLC/transparent), 2× SMCs, SPI, I²C, 2× TDM ports - enables concurrent multi-protocol edge node operation without external co-processors. |
| Memory Interface | 8-bank glueless controller supporting 32-bit SDRAM, SRAM, Flash, EPROM - eliminates external address latches and logic, simplifying BOM and PCB layout for compact designs. |
| PCI Bridge | 32-bit, 66 MHz, PCI 2.2-compliant host/agent bridge with four DMA channels - allows direct attachment of network PHYs, FPGA accelerators, or storage controllers without PCIe-to-PCI bridge ICs. |
| Package & Thermal | 516-pin PBGA (VR, lead-free); RθJA = 27 °C/W (natural convection, single-layer board) - requires minimal heatsinking in fanless industrial enclosures operating below 60 °C ambient. |
Pinout & Package
KMPC8248VRTIEA is housed in a 516-ball plastic ball grid array (PBGA) package with 1.0 mm ball pitch, RoHS-compliant lead-free finish, and thermal pad exposed on underside for enhanced heat dissipation. Package dimensions are 27 mm × 27 mm × 1.7 mm (height).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (1.5 V) | Core logic supply | Must be decoupled with 0.1 µF ceramic + 47 µF bulk capacitor per power quadrant; voltage tolerance ±3% (1.425–1.575 V) ensures stable G2_LE core operation at 400 MHz. |
| VDDH (3.3 V) | I/O supply | Powers all digital I/O banks (60x bus, PCI, FCC, SCC, USB); regulated 3.135–3.465 V required to meet VIH ≥ 2.0 V and VOL ≤ 0.4 V across temperature. |
| CLKIN | Main system clock input | Accepts 25–50 MHz crystal or oscillator; drives both core and CPM PLLs; VIHC ≥ 2.4 V ensures reliable lock under EMI stress. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar integrated communications processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC8313EVRAGDB | PowerPC e300 core (400 MHz), no integrated SEC, single FCC, DDR1 memory controller, 416-pin PBGA | Lacks hardware crypto acceleration; requires external crypto IC for IPsec; lower peripheral integration limits multi-protocol concurrency. | Select when crypto offload is unnecessary and cost sensitivity outweighs security performance; verify SEC absence aligns with threat model. |
| MPC8548CVRAGDB | e500v2 core (1.33 GHz), integrated SEC (AES/SHA), dual DDR2 controller, 783-pin FC-PBGA, 1.0 V core | Higher performance and memory bandwidth; larger package and higher power (6–10 W vs. 1.5–1.8 W) demand active cooling and complex PDN. | Select for next-gen throughput demands (>500 Mbps encrypted) and DDR2 migration path; validate thermal budget and PCB layer count. |
Compared with KMPC8248VRTIEA, MPC8313EVRAGDB offers lower cost and power but omits SEC and one FCC - suitable for non-encrypted bridging. MPC8548CVRAGDB delivers 3× crypto throughput and DDR2 support but increases board area, thermal complexity, and BOM cost - justified only for scalable high-bandwidth deployments.

FAQ
What is the maximum operating frequency of the KMPC8248VRTIEA core?
The KMPC8248VRTIEA core supports a maximum operating frequency of 400 MHz, achieved using an 8:1 internal PLL multiplier on a 50 MHz CLKIN reference. This frequency is validated across the full 0–70 °C ambient temperature range and requires strict adherence to 1.425–1.575 V core supply regulation and proper decoupling per the hardware specification.
Does KMPC8248VRTIEA include hardware encryption acceleration?
Yes, KMPC8248VRTIEA includes a dedicated Security Engine (SEC) that performs AES-128/192/256, DES, 3DES, SHA-1, MD-5, RC4, PKEU, and RNG operations in hardware. This enables line-rate IPsec processing at 100+ Mbps with minimal CPU overhead, distinguishing it from non-SEC variants like MPC8247.
What package type and pin count does KMPC8248VRTIEA use?
KMPC8248VRTIEA uses a 516-ball plastic ball grid array (PBGA) package with VR code designation, lead-free finish, and 1.0 mm ball pitch. Its mechanical dimensions are 27 mm × 27 mm × 1.7 mm, and it features an exposed thermal pad on the underside for improved heat transfer to the PCB ground plane.
Which communication peripherals are integrated into KMPC8248VRTIEA?
KMPC8248VRTIEA integrates two Fast Communication Controllers (FCCs) supporting 10/100 Ethernet and HDLC, three Serial Communication Controllers (SCCs) compatible with UART, HDLC, SDLC, and transparent modes, two Serial Management Controllers (SMCs), SPI, I²C, USB 2.0 full-speed host/slave, and two TDM interfaces - all managed by the on-chip Communications Processor Module (CPM).
Is KMPC8248VRTIEA pin-compatible with other PowerQUICC II devices?
No, KMPC8248VRTIEA is not pin-compatible with other PowerQUICC II devices such as MPC8272 or MPC8247, despite sharing the same 516-ball VR package footprint. Pin functions differ significantly across the family - for example, UTOPIA interface pins exist only on MPC8272/MPC8271, and SEC-related signals are unique to MPC8272/MPC8248 - requiring full schematic and layout revision for substitution.
