For engineers reviewing the MC8641VJ1500KE datasheet, MC8641VJ1500KE pinout, MC8641VJ1500KE application, or MC8641VJ1500KE equivalent, this page delivers verified technical context, validated package mapping (1023-pin FC-CBGA), confirmed electrical operating conditions (VDD_Core = 1.10 V ± 50 mV, TJ = 0–105°C), and real-world interface compatibility across eTSEC, DDR2, PCIe, and SRIO subsystems.

Technical Context

The MC8641VJ1500KE implements a superscalar 32-bit PowerPC ISA e600 core with eleven execution units, separate instruction/data MMUs, and 36-bit real addressing. Its memory subsystem integrates dual DDR/DDR2 controllers supporting up to 300-MHz clock rates and 600-MHz DDR2 data rates, with cache line and page interleaving between controllers.

Connectivity is provided via four eTSECs compliant with IEEE 802.3/802.3u/802.3ab, supporting MII/RGMII/TBI/RTBI physical interfaces and TCP/IP offload; one PCI Express 1.0a interface (2.5 Gbaud per lane); and one Serial RapidIO 1.2 interface (1.25/2.5/3.125 Gbaud per lane) with message-unit and atomic transaction support.

FAQ

What is the core voltage requirement for MC8641VJ1500KE?

The MC8641VJ1500KE requires a nominal core supply voltage of 1.10 V ± 50 mV (VDD_Core0) at 1.5 GHz operation, with strict sequencing: VDD_PLAT and AVDD_PLAT must reach 90% of target before DDR I/O supplies (Dn_GVDD/Dn_MVREF) rise. This specification is validated per Table 2 of the MPC8641D Rev. 3 datasheet and applies directly to MC8641VJ1500KE.

Does MC8641VJ1500KE support DDR2-600 memory?

Yes, MC8641VJ1500KE supports DDR2-600 operation (300 MHz clock, 600 Mbps data rate) with 1.8 V ± 90 mV I/O supply (Dn_GVDD) and differential reference voltage Dn_MVREF = Dn_GVDD/2 ± 1%. The dual DDR2 controllers enable up to 16 GB per channel with interleaving, as confirmed in Section 6 of the MPC8641D hardware specifications.

How many Ethernet controllers does MC8641VJ1500KE integrate?

MC8641VJ1500KE integrates four enhanced three-speed Ethernet controllers (eTSECs), each supporting 10/100/1000 Mbps operation and compliant with IEEE 802.3/802.3u/802.3ab. Each eTSEC supports MII, RMII, GMII, RGMII, TBI, and RTBI physical interfaces, with hardware TCP/IP offload and RMON statistics - all documented in Section 8 of the MPC8641D datasheet.

Is MC8641VJ1500KE pin-compatible with MPC8641D variants?

Yes, MC8641VJ1500KE shares identical 1023-pin FC-CBGA package, pinout, and signal definitions with MPC8641D-series devices (e.g., MPC8641DZQ1500KE), as confirmed in Section 16 ("Package") and Section 17 ("Signal Listings") of the MPC8641D Rev. 3 datasheet. Only core count and thermal/power characteristics differ - no PCB redesign is needed for migration.

What boot interfaces does MC8641VJ1500KE support?

MC8641VJ1500KE supports boot from serial ROM via its dual I²C controllers, using an on-chip boot sequencer that validates configuration data with preamble signature and CRC. This capability is explicitly defined in Section 1.1 ("Key Features") and Section 21 ("Ordering Information") of the MPC8641D datasheet, and applies to all MPC8641 variants including MC8641VJ1500KE.
