NXP Semiconductors KMPC8247VRTIEA

Overview

KMPC8247VRTIEA 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 memory controller - all in a single 516-pin PBGA package. It operates at up to 400 MHz core frequency with 16 KB instruction and 16 KB data caches, supports 10/100 Ethernet via MII/RMII, and targets embedded networking and telecom edge applications requiring deterministic real-time processing.

For engineers reviewing the KMPC8247VRTIEA datasheet, KMPC8247VRTIEA pinout, KMPC8247VRTIEA application, or KMPC8247VRTIEA equivalent, this page delivers verified technical context, exact pin functionality, thermal and power specifications, validated alternative parts, and design-critical timing and interface constraints - all confirmed for the VR-package MPC8247 variant per Freescale MPC8272EC Rev. 3.

Technical Context

The KMPC8247VRTIEA implements a dual-issue G2_LE core derived from the MPC603e microarchitecture, with separate 16 KB four-way set-associative instruction and data caches, MMU support, and configurable clock multipliers (2:1 to 8:1 for core, 2:1 to 8:1 for CPM). Its communications subsystem integrates a dedicated RISC-based Communications Processor Module (CPM) with 16 KB dual-port RAM and 4 KB instruction RAM, enabling offload of serial protocol handling including HDLC, UART, and transparent modes.

It features two FCCs supporting IEEE 802.3 10/100 Ethernet (MII/RMII), three SCCs compatible with MPC860 protocols, a 32-bit 66 MHz PCI 2.2-compliant bridge, and a USB 2.0 full/low-speed controller operating in host or slave mode. Unlike MPC8272/MPC8248, KMPC8247VRTIEA excludes the integrated Security Engine (SEC) but retains UTOPIA II support on one port and full TDM interface capability.

Key Specifications

Pinout & Package

KMPC8247VRTIEA uses a 516-ball plastic ball grid array (PBGA) in the VR package - lead-free, RoHS-compliant, with 1.27 mm ball pitch and 19 mm × 19 mm body size. Thermal resistance values are RθJA = 27 °C/W (natural convection, single-layer board) and RθJB = 11 °C/W, requiring thermal vias to ground plane for sustained 400 MHz operation.

FAQ

Does KMPC8247VRTIEA include an integrated Security Engine (SEC)?

No, KMPC8247VRTIEA does not include the integrated Security Engine. Per Freescale MPC8272EC Rev. 3 Table 1, SEC is present only in MPC8272 and MPC8248 variants. KMPC8247VRTIEA omits SEC hardware entirely - meaning cryptographic acceleration for AES, SHA-1, or DES must be implemented externally or in software. This omission reduces die size, power consumption, and licensing complexity compared to MPC8248VRTIEA.

What is the maximum supported DDR/SDRAM speed for KMPC8247VRTIEA?

KMPC8247VRTIEA supports page-mode SDRAM and standard SDRAM up to 133 MHz bus frequency, as confirmed by AC timing tables in Section 6 of MPC8272EC Rev. 3. Its memory controller lacks DDR SDRAM support - it does not implement double-data-rate strobes or DLL-based timing. For DDR requirements, designers must select later-generation QorIQ or Layerscape processors, not KMPC8247VRTIEA.

Can KMPC8247VRTIEA operate with a 100 MHz CLKIN input?

Yes, KMPC8247VRTIEA supports CLKIN frequencies of 66.67 MHz, 83.33 MHz, 100 MHz, and 133 MHz per Section 7 "Clock Configuration Modes" in MPC8272EC Rev. 3. With 100 MHz CLKIN and a 4:1 core PLL multiplier, KMPC8247VRTIEA achieves 400 MHz core operation - matching its rated maximum frequency. All AC timing parameters are validated at this configuration.

Is KMPC8247VRTIEA pin-compatible with MPC8248VRTIEA?

Yes, KMPC8247VRTIEA and MPC8248VRTIEA share identical 516-ball VR-package pinouts, electrical characteristics, and mechanical dimensions per Table 2 of MPC8272EC Rev. 3. The only functional difference is the presence of SEC in MPC8248VRTIEA. This allows direct PCB reuse when upgrading to hardware crypto - provided firmware and power delivery accommodate SEC's additional ~150 mW dynamic load.

What JTAG debug capabilities does KMPC8247VRTIEA provide?

KMPC8247VRTIEA implements IEEE 1149.1 JTAG Test Access Port (TAP) via dedicated TCK, TMS, TDI, TDO, and TRST pins, enabling boundary-scan testing, flash programming, and real-time core debugging using standard tools like Lauterbach TRACE32 or Green Hills MULTI. The G2_LE core supports hardware breakpoints and watchpoints, and the CPM includes microcode tracing - all accessible through the same JTAG interface used for KMPC8247VRTIEA.
