It operates at 1333 MHz core frequency and 533 MHz platform frequency with 1.05 V core supply, targeting networking infrastructure, wireless base stations, and storage controllers requiring high-throughput packet processing and deterministic real-time response.

For engineers reviewing the MC8641DVJ1333JE datasheet, MC8641DVJ1333JE pinout, MC8641DVJ1333JE application, or MC8641DVJ1333JE equivalent, this page delivers verified technical context on its dual DDR2/DDR SDRAM controllers, four eTSEC Ethernet interfaces (10/100/1000 Mbps), PCI Express 1.0a x1/x2/x4/x8 support, Serial RapidIO 1.2 compatibility, and 1023-pin FC-CBGA package - all confirmed for the exact MC8641DVJ1333JE variant.

Technical Context

The MC8641DVJ1333JE implements a single e600 core with eleven independent execution units, separate MMUs for instruction and data, and hardware support for multiprocessing via MPX coherency module. Its memory subsystem includes two 64-bit DDR/DDR2 controllers (72-bit with ECC), supporting up to 300-MHz clock and 600-MHz DDR2 data rates.

Connectivity integrates four enhanced three-speed Ethernet controllers (eTSECs) with MII/RGMII/TBI/RTBI physical layer support, PCI Express 1.0a with x1–x8 link widths, and Serial RapidIO 1.2 with 1x/4x LP-Serial links at 2.5 Gbaud per lane. All I/O supplies are segregated: OVDD = 3.3 V, LVDD/TVDD = 2.5/3.3 V, Dn_GVDD = 1.8/2.5 V, and VDD_Core = 1.05 V.

Manufacturer

Freescale Semiconductor was a fabless semiconductor company specializing in embedded processors, analog, and connectivity solutions before its acquisition by NXP Semiconductors in 2015. It pioneered Power Architecture implementations for networking and automotive markets.

The MPC8641 family was designed as a high-performance integrated host processor for carrier-grade networking equipment, combining e600 compute capability with multi-protocol I/O (eTSEC, RapidIO, PCIe) and memory subsystems optimized for packet-forwarding and control-plane workloads.

FAQ

What is the core voltage requirement for MC8641DVJ1333JE?

The MC8641DVJ1333JE requires a nominal core supply voltage of 1.05 V ± 50 mV, as specified in Table 2 of the hardware specifications document. This voltage applies specifically to the 1333 MHz speed grade and must be stabilized before platform supply rails reach 90% of their target value during power-up sequencing. Deviation beyond ±50 mV risks timing violations or functional failure.

Does MC8641DVJ1333JE support DDR2 memory?

Yes, MC8641DVJ1333JE supports DDR2 SDRAM at up to 600 MHz data rates using its dual 64-bit controllers with 72-bit bus width (64-bit + 8-bit ECC). The required I/O supply is Dn_GVDD = 1.8 V ± 90 mV, and reference voltage Dn_MVREF must be set to Dn_GVDD/2 ± 1%. DDR2 operation is validated per JEDEC JESD79-2 specification.

How many Ethernet interfaces does MC8641DVJ1333JE integrate?

The MC8641DVJ1333JE integrates four enhanced three-speed Ethernet controllers (eTSECs), each supporting 10/100/1000 Mbps operation. They support MII, RMII, GMII, RGMII, TBI, and RTBI physical interfaces, with hardware offload for TCP/IP checksum, VLAN tagging, and RMON statistics - all confirmed in Section 8 of the hardware specifications.

What package type is used for MC8641DVJ1333JE?

MC8641DVJ1333JE uses a 1023-pin Hi-CTE flip-chip ceramic ball grid array (FC-CBGA) package, as stated in Section 16 of the hardware specifications. The package has a 35 × 35 mm body size, 1.0 mm ball pitch, and requires specific PCB pad layout, solder mask definition, and thermal via patterns per Freescale's packaging guidelines.

Is MC8641DVJ1333JE pin-compatible with MPC8641D variants?

No, MC8641DVJ1333JE is not pin-compatible with dual-core MPC8641D variants such as MPC8641DVL1333JE. Although both use the same 1023-pin FC-CBGA package, the pin functions differ significantly due to additional core-related signals (e.g., Core1-specific cache coherency, interrupt, and debug lines) present only on MPC8641D devices.
