Overview

MC8641VJ1000NE from Freescale Semiconductor is a single-core Power Architecture® e600-based integrated host processor with 32-Kbyte L1 instruction and data caches, 1-Mbyte unified L2 cache with ECC, dual 64-bit DDR/DDR2 SDRAM controllers (72-bit with ECC), four enhanced three-speed Ethernet controllers (10/100/1000 Mbps), PCI Express 1.0a (x1/x2/x4/x8), Serial RapidIO 1.2 (1x/4x, 2.5 Gbps/lane), and integrated programmable interrupt controller - deployed in networking infrastructure, wireless baseband units, and storage control systems.

For engineers reviewing the MC8641VJ1000NE datasheet, MC8641VJ1000NE pinout, MC8641VJ1000NE application, or MC8641VJ1000NE equivalent, key selection criteria include confirmed 1000 MHz core frequency at 0.95 V core supply, DDR2-1066 support via dual 64-bit controllers, eTSEC interface flexibility (MII/RGMII/TBI/RTBI), PCIe 1.0a lane scalability, and FC-CBGA-1023 package thermal performance up to 105°C junction temperature.

Technical Context

The MC8641VJ1000NE implements a superscalar 32-bit e600 core with eleven execution units, separate instruction/data MMUs, 36-bit real addressing, and hardware multiprocessing support. Its MPX coherency module enables cache-coherent inter-core communication and supports ten local address windows plus two default windows.

It integrates dual DDR/DDR2 memory controllers supporting up to 300-MHz clock rates (600-MHz data rate), four eTSECs with TCP/IP offload and RMON statistics, and a four-channel DMA controller accessible by both local and remote masters - all synchronized via a platform bus operating at 400–600 MHz depending on voltage/frequency binning.

FAQ

What is the confirmed core frequency and voltage specification for MC8641VJ1000NE?

The MC8641VJ1000NE is explicitly rated for 1000 MHz operation at 0.95 V VDD_Core0, as validated in Table 6 of the MPC8641D Rev. 3 specification under "Typical" and "Thermal" power modes. This binning is distinct from higher-frequency variants (e.g., 1333 MHz at 1.05 V) and requires matching platform supply sequencing per Figure 3.

Does MC8641VJ1000NE support DDR2-1066 memory, and what are the interface requirements?

Yes, MC8641VJ1000NE supports DDR2-1066 (533 MHz data rate) via its dual 64-bit DDR2 SDRAM controllers. It requires D1_GVDD/D2_GVDD at 1.8 V ± 90 mV and Dn_MVREF at Dn_GVDD/2 ± 1%, compliant with SSTL-18 electrical standards per Section 6 of the specification.

How many Ethernet controllers does MC8641VJ1000NE integrate, and which physical interfaces do they support?

The MC8641VJ1000NE integrates four enhanced three-speed Ethernet controllers (eTSECs), each supporting 10/100/1000 Mbps. They natively support MII, RMII, GMII, RGMII, TBI, and RTBI physical layer interfaces - enabling flexible PHY selection for copper/fiber backhaul and management links.

What is the package type and thermal rating of MC8641VJ1000NE?

MC8641VJ1000NE uses a 1023-pin Hi-CTE flip-chip ceramic ball grid array (FC-CBGA) package. Its maximum junction temperature is 105°C, and it is characterized for thermal operation up to this limit under typical and maximum power conditions per Table 6.

Is MC8641VJ1000NE pin-compatible with any dual-core variant of the MPC8641 family?

MC8641VJ1000NE shares the same FC-CBGA-1023 package and pinout with the dual-core MPC8641DZQ1000NE, including identical power, clock, reset, DDR, and I/O ball assignments. However, core-specific signals (e.g., Core1-related interrupts and cache coherency lines) are no-conn on the single-core variant.
