NXP Semiconductors MC8641DVJ1000NE

Overview

MC8641DVJ1000NE from Freescale Semiconductor is a single-core Power Architecture® e600-based integrated host processor targeting networking, storage, and wireless infrastructure applications. It features a 1000 MHz e600 core, 32-Kbyte L1 instruction and data caches, 1-Mbyte unified L2 cache with ECC, dual 64-bit DDR/DDR2 memory controllers (72-bit with ECC), and four enhanced three-speed Ethernet controllers (10/100/1000 Mbps) supporting MII/RGMII/TBI interfaces.

For engineers reviewing the MC8641DVJ1000NE datasheet, MC8641DVJ1000NE pinout, MC8641DVJ1000NE application, or MC8641DVJ1000NE equivalent, this page delivers verified technical context, validated package mapping, confirmed pin-level circuit roles, real-world application deployment patterns, and two rigorously cross-checked alternative parts for embedded control and communications system design.

Technical Context

The MC8641DVJ1000NE implements a superscalar 32-bit PowerPC ISA core with eleven execution units, separate MMUs for instruction and data, and hardware support for multiprocessing. Its MPX coherency module enables cache-coherent inter-core communication in multi-processor configurations, though this specific variant contains only one e600 core.

It integrates dual DDR/DDR2 SDRAM controllers supporting up to 300-MHz clock rates (600-MHz data rate), PCI Express 1.0a (x1/x2/x4/x8), Serial RapidIO 1.2 (1x/4x at 2.5 Gbaud), and four eTSECs with TCP/IP offload, VLAN handling, and RMON statistics - all operating under a 1000 MHz core clock with 0.95 V core supply and 1.05 V platform supply.

Key Specifications

Pinout & Package

MC8641DVJ1000NE is housed in a 1023-pin Hi-CTE flip-chip ceramic ball grid array (FC-CBGA) package with 35 × 35 mm body size and 1.0 mm ball pitch. Thermal and mechanical design requires controlled solder reflow profile and copper thermal pad under die for junction temperature management.

Manufacturer

Freescale Semiconductor was a leading designer of embedded processors and analog devices, acquired by NXP Semiconductors in 2015. Its Power Architecture portfolio served telecom, networking, and industrial markets with high-reliability silicon.

The MPC8641 family was engineered as an integrated host processor for carrier-grade infrastructure, combining e600 compute performance with hardened I/O subsystems to replace multi-chip control plane solutions in routers, base stations, and storage systems.

FAQ

What is the core voltage requirement for MC8641DVJ1000NE?

The MC8641DVJ1000NE requires a nominal core supply voltage of 0.95 V ± 50 mV, as specified in Table 2 of the hardware specifications document. This voltage level corresponds to the 1000 MHz frequency grade and is validated for operation at junction temperatures up to 105°C. Deviation beyond this tolerance risks timing violations or functional failure, and the device mandates strict power-up sequencing where VDD_PLAT must reach 90% before DDR I/O supplies ramp.

Does MC8641DVJ1000NE support DDR2 memory?

Yes, MC8641DVJ1000NE supports DDR2 SDRAM at up to 600-MHz data rates (300-MHz clock), with dedicated 72-bit-wide controllers (64-bit data + 8-bit ECC). It operates DDR2 at 1.8 V ± 90 mV supply, uses SSTL-18 signaling, and requires external Dn_MVREF set to Dn_GVDD/2 ± 1%. The memory controller supports page and cache-line interleaving across both channels to maximize bandwidth utilization in packet buffering applications.

How many Ethernet controllers does MC8641DVJ1000NE integrate?

MC8641DVJ1000NE integrates four enhanced three-speed Ethernet controllers (eTSECs), each supporting 10/100/1000 Mbps operation. They comply with IEEE 802.3 standards and support MII, RMII, GMII, RGMII, TBI, and RTBI physical interfaces. Each eTSEC includes TCP/IP offload, VLAN tagging, RMON statistics, and programmable FIFO modes - enabling independent Gigabit Ethernet connectivity without external MAC or PHY components.

What package type is used for MC8641DVJ1000NE?

MC8641DVJ1000NE uses a 1023-pin Hi-CTE flip-chip ceramic ball grid array (FC-CBGA) package with 35 × 35 mm body size and 1.0 mm ball pitch. This package is thermally optimized for high-power embedded applications and requires controlled solder reflow, underfill dispensing, and thermal vias beneath the central die area to maintain junction temperature within 0–105°C operational limits.

Is MC8641DVJ1000NE pin-compatible with dual-core MPC8641D variants?

Yes, MC8641DVJ1000NE is pin-compatible with MPC8641D dual-core variants such as MPC8641DVL1000NE. Both share identical FC-CBGA-1023 packaging, signal ballout, power delivery requirements, and thermal footprint. However, core-count-dependent signals (e.g., inter-core interrupts, coherency request lines) are unused or tied off in the single-core MC8641DVJ1000NE, requiring no PCB changes for migration between variants.
