NXP Semiconductors MC8641VU1333JE

Overview

The MC8641VU1333JE from Freescale Semiconductor is a single-core Power Architecture® e600-based integrated host processor operating at 1333 MHz, featuring a 32-bit superscalar CPU, 32-Kbyte L1 instruction and data caches, and a 1-Mbyte unified L2 cache with ECC. It integrates dual DDR/DDR2 memory controllers (64-bit, up to 600 MHz), 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 dual I²C, DUART, JTAG, and local bus interfaces. It targets high-performance networking and embedded infrastructure applications.

For engineers reviewing the MC8641VU1333JE datasheet, MC8641VU1333JE pinout, MC8641VU1333JE application, or MC8641VU1333JE equivalent, key selection considerations include its 1333 MHz core frequency, 1.05 V core supply, 1023-pin FC-CBGA package, dual DDR2-600 support, and integrated eTSEC, PCIe, and SRIO interfaces for carrier-grade routing, storage controller, and wireless baseband platforms.

Technical Context

The MC8641VU1333JE implements a single e600 core with eleven execution units, separate instruction/data MMUs, and hardware multiprocessing support. Its MPX coherency module enables cache coherency across multiple masters, while ATMUs provide eight inbound/outbound address translation windows for PCI Express and Serial RapidIO.

It supports simultaneous high-bandwidth I/O via four independent eTSECs with RGMII/GMII/MII/TBI interfaces, TCP/IP offload, VLAN handling, and RMON statistics - all backed by a four-channel DMA controller and programmable OpenPIC-compliant interrupt controller supporting 64 interrupt sources and eight high-resolution timers.

Key Specifications

Pinout & Package

MC8641VU1333JE 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 design requires solder-reflow-compatible underfill and copper thermal slug integration per Freescale AN3987.

FAQ

What is the maximum DDR2 data rate supported by the MC8641VU1333JE?

The MC8641VU1333JE supports DDR2-600 operation (300 MHz clock, 600 Mbps per pin) on both memory controllers. This is confirmed in Section 6 of the hardware specifications, where electrical timing parameters for DQ/DQS signals are defined for 600 Mbps operation with 1.8 V ± 90 mV supply. The MC8641VU1333JE achieves this using SSTL-18 signaling and programmable drive strength calibration via DDR Control Driver registers.

Does the MC8641VU1333JE support PCIe Gen1 x8 mode?

Yes, the MC8641VU1333JE supports PCIe 1.0a compliant x1, x2, x4, and x8 link widths at 2.5 Gbaud per lane. Section 14 of the hardware specification confirms full x8 configuration capability, with AC timing validated for 2.0 Gbps per lane. The MC8641VU1333JE implements the PCIe root complex function and requires external SerDes termination per Figure 14-10.

What is the recommended core supply voltage for the MC8641VU1333JE?

The recommended core supply voltage for the MC8641VU1333JE is 1.05 V ± 50 mV, as specified in Table 2 (Recommended Operating Conditions) for devices marked with a 1333 MHz core frequency. This voltage applies to both VDD_Core0 and AVDD_Core0, which must be tracked within 100 mV of each other during operation. The MC8641VU1333JE does not support 0.95 V core operation - that variant is designated MC8641xxx1000NX.

How many Ethernet controllers does the MC8641VU1333JE integrate?

The MC8641VU1333JE integrates four enhanced three-speed Ethernet controllers (eTSECs), each supporting 10/100/1000 Mbps operation. As documented in Section 8, all four eTSECs support MII, RMII, GMII, RGMII, TBI, and RTBI physical layer interfaces, with hardware features including TCP/IP offload, VLAN handling, and RMON statistics. The MC8641VU1333JE uses these controllers for multi-port routing, switching, and protocol bridging tasks.

Is the MC8641VU1333JE pin-compatible with the MPC8641D dual-core variant?

No, the MC8641VU1333JE is not pin-compatible with the MPC8641D dual-core variant. Although both use the same 1023-pin FC-CBGA package, Section 16 notes functional differences in pin assignment: MPC8641D dedicates additional pins to Core1-specific signals (e.g., VDD_Core1, AVDD_Core1, Core1 interrupt lines), while the MC8641VU1333JE repurposes those balls for alternate functions or leaves them NC. PCB layout must be specific to the single-core MC8641VU1333JE.
