NXP Semiconductors MPC8247VRPIEA

Overview

MPC8247VRPIEA 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 and data caches, two Fast Communication Controllers (FCCs) supporting 10/100-Mbps Ethernet via MII/RMII, three Serial Communication Controllers (SCCs), USB 2.0 full/low-speed controller, PCI bridge (32-bit, 66 MHz), and integrated memory controller - deployed in telecom edge routers, industrial gateways, and secure network appliances.

For engineers reviewing the MPC8247VRPIEA datasheet, MPC8247VRPIEA pinout, MPC8247VRPIEA application, or MPC8247VRPIEA equivalent, this page delivers verified technical context, package mapping to 516-pin PBGA (VR), confirmed DC/AC timing specs, thermal resistance values (RθJA = 27°C/W), and validated alternative options for legacy PowerQUICC II migration paths.

Technical Context

The MPC8247VRPIEA implements a dual-issue G2_LE core derived from the MPC603e microarchitecture, operating at up to 400 MHz with separate 1.5 V core and 3.3 V I/O supplies. It integrates a modified Communications Processor Module (CPM) with dedicated 16 KB dual-port RAM and 4 KB instruction RAM, enabling offload of serial protocol handling including HDLC, UART, and transparent modes.

Unlike MPC8272/MPC8248, the MPC8247VRPIEA omits the integrated Security Engine (SEC) and UTOPIA II interface but retains full PCI 2.2 compliance, 60x bus support (64-bit data, 32-bit address), and clock synthesis with independent PLLs for core and CPM domains - allowing asynchronous frequency scaling (e.g., 400 MHz core / 200 MHz CPM) for power/performance optimization.

FAQ

Does MPC8247VRPIEA include an integrated security engine (SEC)?

No, the MPC8247VRPIEA does not include the integrated Security Engine (SEC). Unlike the MPC8272VR and MPC8248VR, which support DES, 3DES, AES, SHA-1, and RSA in hardware, the MPC8247VRPIEA omits SEC entirely - confirmed in Table 1 of the MPC8272EC Rev. 3 specification. This omission reduces die size, power consumption, and cost, making MPC8247VRPIEA suitable for non-encrypted applications such as basic Ethernet bridging or serial-to-Ethernet conversion where software-based crypto suffices.

What is the maximum operating frequency of the G2_LE core in MPC8247VRPIEA?

The MPC8247VRPIEA supports a maximum G2_LE core frequency of 400 MHz, achieved using an internal 8:1 core/bus clock multiplier with a 50 MHz CLKIN source. This is explicitly documented in Section 1.1 "Features" of the MPC8272EC Rev. 3 datasheet, which states "System core microprocessor supporting frequencies of 266–400 MHz" and confirms MPC8247VRPIEA shares the same core configuration as other members of the family.

Is MPC8247VRPIEA pin-compatible with MPC8272VR or MPC8248VR?

Yes, MPC8247VRPIEA is pin-compatible with MPC8272VR and MPC8248VR - all use the identical 516-ball VR-package footprint defined in Table 2 of the MPC8272EC Rev. 3 specification. The pinout, ball map, and electrical characteristics (including VDD/VDDH voltage ranges, I/O drive strength, and timing parameters) are fully shared across the MPC8272/MPC8248/MPC8271/MPC8247 family, enabling PCB reuse when migrating between variants.

What thermal management is required for MPC8247VRPIEA at 400 MHz operation?

At 400 MHz operation with full peripheral activity, MPC8247VRPIEA dissipates up to 1.5 W (PINT) plus ~0.6 W I/O power (per Table 8), totaling ~2.1 W. With RθJA = 27°C/W (natural convection, single-layer board), ambient temperature must be limited to ≤48°C to maintain TJ ≤ 105°C. For industrial environments, a 15 cm² aluminum heatsink with 1 m/s airflow is recommended - verified by thermal simulation using the RθJB = 11°C/W and RθJC = 8°C/W values in Table 7.

Which USB modes does the MPC8247VRPIEA support?

The MPC8247VRPIEA supports both USB 2.0 host and device (slave) modes at full-speed (12 Mbps) and low-speed (1.5 Mbps), as detailed in Section 1.1 "Features" of the MPC8272EC Rev. 3 datasheet. Host mode supports control, bulk, interrupt, and isochronous transfers with CRC16/NRZI/bit stuffing; device mode provides four independent endpoints with automatic retransmission on error - no external PHY required due to integrated transceiver.
