Product details
Overview
KMPC8247CVRTIEA from NXP Semiconductors (formerly Freescale) is a PowerQUICC II integrated communications processor featuring a 32-bit Power Architecture® G2_LE core, dual 16 KB instruction/data caches, two Fast Communication Controllers (FCCs), three Serial Communication Controllers (SCCs), PCI bridge, USB 2.0 controller, and memory controller - all in a single 516-pin PBGA package. It operates at up to 400 MHz core frequency with separate 1.5 V core and 3.3 V I/O supplies, targeting embedded networking and telecom edge applications.
For engineers reviewing the KMPC8247CVRTIEA datasheet, KMPC8247CVRTIEA pinout, KMPC8247CVRTIEA application, or KMPC8247CVRTIEA equivalent, this page delivers verified technical context, validated pin functions, confirmed power and timing specs, real-world use scenarios, and two rigorously cross-checked alternative parts for design continuity.
Technical Context
The KMPC8247CVRTIEA integrates a dual-issue G2_LE core (MPC603e derivative) with MMU, 16 KB I-cache and 16 KB D-cache, and a dedicated Communications Processor Module (CPM) running independently via dual-port RAM and microcode. Core and CPM clocks are generated by separate PLLs, enabling asynchronous operation at ratios up to 8:1 for performance/power optimization.
It supports 64-bit/32-bit 60x bus (up to 133 MHz), 32-bit PCI 2.2 interface (66 MHz), two 10/100 Mbps Ethernet ports via MII/RMII, UTOPIA II (MPC8272/MPC8271 only - not supported on KMPC8247CVRTIEA), and USB 2.0 full/low-speed host/slave modes. Security Engine (SEC) is absent - confirmed by Table 1 functionality matrix.

Equivalent & Alternatives
The following parts are listed as comparable options for similar integrated communications processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC8248VR | Includes integrated Security Engine (SEC) supporting AES, DES, SHA-1; otherwise identical architecture, pinout, and package | Required where hardware-accelerated encryption (e.g., IPsec, SSL offload) is mandatory | Select MPC8248VR when SEC functionality is needed; KMPC8247CVRTIEA remains optimal for cost-sensitive non-secure applications |
| MPC8271VR | Same core, CPM, FCC/SCC count, and VR package; adds UTOPIA II interface and ATM SAR support - absent in KMPC8247CVRTIEA | Suitable for ATM-based metro edge deployments requiring UTOPIA PHY interfacing | MPC8271VR is functionally superset for ATM; KMPC8247CVRTIEA offers identical non-ATM capabilities at lower cost and complexity |
Compared with MPC8248VR and MPC8271VR, KMPC8247CVRTIEA provides identical compute, I/O, and memory subsystem capabilities but omits SEC and UTOPIA - making it the leanest, most cost-effective choice for Ethernet- and serial-centric embedded communications where those features are unnecessary.

FAQ
Does KMPC8247CVRTIEA include an integrated security engine (SEC)?
No, KMPC8247CVRTIEA does not include a security engine. Per Table 1 in the MPC8272EC Rev. 3 specification, SEC is present only in MPC8272 and MPC8248 variants. KMPC8247CVRTIEA shares identical core, CPM, FCC, and memory architecture with those parts but excludes SEC hardware - confirmed by functional matrix and block diagram annotations.
What is the maximum operating frequency of the KMPC8247CVRTIEA core?
The KMPC8247CVRTIEA core operates at up to 400 MHz, achieved via internal PLL multiplication (e.g., 100 MHz CLKIN × 4:1 ratio). This is verified in Table 8 (Power Dissipation) and Section 1.1 Features, which states "system core microprocessor supporting frequencies of 266–400 MHz" for all MPC8272 family members including KMPC8247CVRTIEA.
Is KMPC8247CVRTIEA pin-compatible with MPC8248VR?
Yes, KMPC8247CVRTIEA and MPC8248VR are pin-compatible within the VR package. Table 2 confirms both devices share the "VR (516 PBGA-Lead free)" package code, and the pinout section (Section 8) applies uniformly across all VR variants in the MPC8272 family - differences are internal (SEC presence) only.
What voltage supplies are required for KMPC8247CVRTIEA operation?
KMPC8247CVRTIEA requires two independent supplies: 1.5 V ±0.075 V (VDD) for the core logic domain and 3.3 V ±0.165 V (VDDH) for all I/O banks. These values are specified in Table 4 (Recommended Operating Conditions) and must be sequenced properly - VDD/VCCSYN should be raised before or simultaneously with VDDH during power-on reset.
Does KMPC8247CVRTIEA support UTOPIA II interface?
No, KMPC8247CVRTIEA does not support UTOPIA II. Table 1 explicitly lists UTOPIA II Ports as "0" for MPC8247, while MPC8272 and MPC8271 show "1". The block diagram (Figure 1) also annotates UTOPIA as "MPC8272/8271 only", confirming KMPC8247CVRTIEA lacks this interface.
