NXP Semiconductors MPC8247CVRTIEA

Overview

MPC8247CVRTIEA from Freescale Semiconductor is a PowerQUICC II family integrated communications processor featuring a 32-bit Power Architecture® G2_LE core (266–400 MHz), dual 16 KB instruction/data caches, integrated CPM with three SCCs and two FCCs, PCI bridge (32-bit, 66 MHz), USB 2.0 controller, and 516-pin PBGA (VR) package. It targets embedded networking gateways, industrial routers, and telecom edge devices requiring deterministic real-time communication processing.

For engineers reviewing the MPC8247CVRTIEA datasheet, MPC8247CVRTIEA pinout, MPC8247CVRTIEA application, or MPC8247CVRTIEA equivalent, key selection considerations include its 266–400 MHz CPU frequency range, absence of integrated security engine (SEC), UTOPIA II port exclusion, and VR-package thermal profile (RθJA = 27°C/W on single-layer board).

Technical Context

The MPC8247CVRTIEA implements a dual-issue G2_LE core derived from the MPC603e microprocessor, with physically addressed, four-way set-associative caches and a Power Architecture-compliant MMU. Its CPM executes communications tasks independently via 16 KB dual-port RAM and 4 KB instruction RAM, supporting HDLC, UART, Ethernet (MII/RMII), and TDM protocols.

It integrates a 60x-to-PCI bridge compliant with PCI Specification 2.2 (32-bit, 66 MHz, 3.3 V), supporting host/peripheral modes, DMA streaming, and I2O. Clocking uses separate PLLs for CPU (ratios 2:1 to 8:1) and CPM (ratios 2:1 to 8:1), enabling independent frequency scaling for power/performance optimization.

FAQ

Does MPC8247CVRTIEA include an integrated security engine (SEC)?

No, MPC8247CVRTIEA does not include an integrated security engine. Unlike the MPC8248CVRTIEA and MPC8272CVRTIEA, the MPC8247CVRTIEA omits the SEC block that accelerates DES, AES, SHA-1, and RSA operations. This omission reduces die size and cost, making MPC8247CVRTIEA appropriate for non-encrypted control-plane applications where cryptographic offload is unnecessary. For secure boot or IPsec, MPC8248CVRTIEA is the direct family alternative.

What is the maximum CPU frequency supported by MPC8247CVRTIEA?

The MPC8247CVRTIEA supports a maximum CPU frequency of 400 MHz, achieved using a 50 MHz CLKIN input with an internal 8:1 PLL multiplier. Its operational range spans 266–400 MHz depending on clock configuration and voltage (VDD = 1.425–1.575 V). Frequency selection is controlled via SIUMCR register bits, and thermal limits (Tj ≤ 105°C) must be maintained at sustained 400 MHz operation using appropriate PCB layout and airflow.

Which package type does MPC8247CVRTIEA use, and what are its thermal characteristics?

MPC8247CVRTIEA uses the 516-pin VR package-a lead-free, very thin fine-pitch BGA with 27 mm × 27 mm body and 1.0 mm ball pitch. Its thermal resistance is RθJA = 27°C/W under natural convection on a single-layer board and RθJB = 11°C/W (junction-to-board), indicating primary heat dissipation occurs through the PCB. These values require adherence to Freescale's layout guidelines: dedicated power/ground planes, 0.1 µF + 47 µF decoupling per supply rail, and minimized trace lengths for high-speed buses.

Can MPC8247CVRTIEA support UTOPIA II interface for ATM PHY connectivity?

No, MPC8247CVRTIEA does not support UTOPIA II. According to Table 1 in the MPC8272EC specification, UTOPIA II Ports are present only on the MPC8272 and MPC8271 variants-not on MPC8247CVRTIEA or MPC8248CVRTIEA. Attempting to route UTOPIA signals to MPC8247CVRTIEA will result in undefined behavior, as those pins are either reserved or repurposed. For UTOPIA II, select MPC8271CVR1A instead.

What are the key differences between MPC8247CVRTIEA and MPC8271CVR1A?

MPC8247CVRTIEA and MPC8271CVR1A share identical CPU core, cache, CPM, FCC/SCC count, PCI bridge, and USB 2.0 functionality-but differ critically in peripheral inclusion: MPC8271CVR1A adds UTOPIA II and ATM SAR support (enabling 155 Mbps full-duplex ATM), while omitting the security engine found in MPC8248. MPC8247CVRTIEA excludes both UTOPIA II and SEC, targeting general-purpose communications processing where neither telecom PHY nor crypto acceleration is needed.
