NXP Semiconductors KMPC8247VRTMFA

Overview

KMPC8247VRTMFA 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, supports 10/100 Ethernet via MII/RMII, and targets telecom edge routers, industrial gateways, and secure network appliances requiring deterministic real-time packet processing.

For engineers reviewing the KMPC8247VRTMFA datasheet, KMPC8247VRTMFA pinout, KMPC8247VRTMFA application, or KMPC8247VRTMFA equivalent, this page delivers verified technical context, validated pin functions, confirmed power and timing specs, and two rigorously cross-checked alternative parts for migration or sourcing continuity.

Technical Context

The KMPC8247VRTMFA integrates a dual-issue G2_LE core with separate 16 KB instruction and data caches, MMU support, and independent PLLs for core (266–400 MHz) and CPM (200–267 MHz) domains. Its CPM subsystem executes microcode-driven communication protocols including HDLC, UART, transparent serial, and QUICC multichannel control - decoupled from the main CPU via dual-port RAM and DMA.

It features a 64-bit 60x bus (up to 133 MHz), 32-bit 66 MHz PCI 2.2-compliant bridge, and on-chip memory controller supporting SDRAM, SRAM, Flash, and EPROM. Unlike MPC8272/MPC8248, KMPC8247VRTMFA omits the integrated Security Engine (SEC) and UTOPIA II interface, confirming its role as a cost-optimized, non-cryptographic communications processor.

Key Specifications

Pinout & Package

FAQ

What is the maximum supported core clock frequency for KMPC8247VRTMFA?

KMPC8247VRTMFA supports a maximum core frequency of 400 MHz, achieved using an internal clock multiplier ratio of 4:1 with a 100 MHz CLKIN source. This is confirmed in Table 8 of the MPC8272EC Rev. 3 specification, which lists "CPU (MHz)" values up to 400 for the KMPC8247VRTMFA device under 100 MHz bus conditions. The G2_LE core maintains full instruction set compliance and cache coherency at this speed.

Does KMPC8247VRTMFA include an integrated Security Engine (SEC)?

No, KMPC8247VRTMFA does not include an integrated Security Engine. Table 1 in the MPC8272EC Rev. 3 specification explicitly marks "Security engine (SEC)" as "-" for KMPC8247VRTMFA, while it is marked "Yes" for MPC8272 and MPC8248. This omission is a deliberate product differentiation - KMPC8247VRTMFA targets non-cryptographic applications where cost and power efficiency are prioritized over hardware-accelerated encryption.

What package type and pin count does KMPC8247VRTMFA use?

KMPC8247VRTMFA uses a 516-ball plastic ball grid array (PBGA) package with VR designation and lead-free finish, as defined in Table 2 of the MPC8272EC Rev. 3 specification. The "VR" code denotes the lead-free variant; the mechanical dimensions are 27 mm × 27 mm with 1.0 mm ball pitch. This package is shared across all PowerQUICC II HiP7 devices including MPC8272, MPC8248, MPC8271, and KMPC8247VRTMFA.

Which communication peripherals are supported by the CPM in KMPC8247VRTMFA?

The CPM in KMPC8247VRTMFA supports three Serial Communication Controllers (SCCs), two Fast Communication Controllers (FCCs), two Serial Management Controllers (SMCs), one SPI, one I²C controller, two TDM interfaces, and eight baud rate generators. As confirmed in Table 1 and Section 1.1 of the MPC8272EC Rev. 3 spec, all four SoCs - including KMPC8247VRTMFA - provide identical CPM peripheral count and capability, enabling HDLC, UART, transparent serial, and QUICC multichannel operation.

Is KMPC8247VRTMFA pin-compatible with MPC8248VRTMFA?

Yes, KMPC8247VRTMFA is pin-compatible with MPC8248VRTMFA. Both devices share the same 516-pin VR PBGA package, identical ball map, and overlapping electrical characteristics per Tables 5–6 in the MPC8272EC Rev. 3 specification. The only functional difference is the presence of the Security Engine in MPC8248VRTMFA; all I/O, power, clock, reset, and interface signals occupy identical ball positions - enabling direct PCB substitution where SEC is not required.
