NXP Semiconductors MC8641DHX1000NE

Overview

MC8641DHX1000NE from Freescale Semiconductor is a single-core Power Architecture® e600-based integrated host processor targeting networking, storage, and wireless infrastructure applications. It features a 32-bit superscalar CPU with 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), four enhanced three-speed Ethernet controllers (10/100/1000 Mbps), PCI Express 1.0a x1/x2/x4/x8 interface, and Serial RapidIO 1.2 1x/4x support.

For engineers reviewing the MC8641DHX1000NE datasheet, MC8641DHX1000NE pinout, MC8641DHX1000NE application, or MC8641DHX1000NE equivalent, key selection considerations include its 1000 MHz core frequency, 0.95 V core supply requirement, 1023-pin FC-CBGA package, dual DDR2-533 support, and eTSEC interface flexibility across MII/RGMII/TBI physical layers.

Technical Context

The MC8641DHX1000NE implements a single e600 core with eleven independent execution units, separate instruction and data MMUs, and hardware multiprocessing support. Its MPX coherency module enables scalable platform bus interconnect, while ATMUs provide eight local address windows and configurable inbound/outbound translations for PCI Express and Serial RapidIO.

Memory subsystem includes two independent 64-bit DDR/DDR2 controllers supporting up to 300-MHz clocking and 16 Gbytes per channel, with cache-line and page interleaving. The four eTSECs integrate TCP/IP offload, VLAN handling, RMON statistics, and MII management interfaces - all compliant with IEEE 802.3/802.3u/802.3z standards.

Key Specifications

Pinout & Package

MC8641DHX1000NE 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 sphere reflow profile compliance per J-STD-020 and underfill for mechanical reliability.

Manufacturer

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

The MPC8641 family was engineered specifically for carrier-grade communications equipment, emphasizing deterministic Ethernet timing, DDR2 memory bandwidth, and RapidIO/PCIe interconnect flexibility in thermally constrained environments.

FAQ

What is the core voltage requirement for MC8641DHX1000NE?

The MC8641DHX1000NE requires a nominal core supply voltage of 0.95 V ± 50 mV, as specified in Table 2 of the hardware specifications document. This voltage must be applied before DDR I/O supplies and maintained within 100 mV of the associated AVDD_Core0 supply. Deviation beyond this tolerance risks timing violations or functional failure during 1000 MHz operation.

Does MC8641DHX1000NE support DDR2-600 memory?

No, MC8641DHX1000NE does not support DDR2-600. Its DDR2 interface is rated for up to 533 MT/s (DDR2-533), as confirmed in Section 1.1 "Key Features" and Table 6 "Power Dissipation (Single Core)" which lists 500 MHz platform frequency at 1000 MHz core speed. The 600 MHz DDR2 rate is only supported on higher-frequency variants like the 1500 MHz MPC8641D.

How many eTSEC controllers does MC8641DHX1000NE integrate?

The MC8641DHX1000NE integrates exactly four enhanced three-speed Ethernet controllers (eTSECs), each supporting 10/100/1000 Mbps operation. This is explicitly stated in Section 1.1 "Key Features" and illustrated in Figure 1. All four eTSECs support MII, RMII, GMII, RGMII, TBI, and RTBI physical interfaces with full-duplex FIFO mode capability.

What package type is used for MC8641DHX1000NE?

MC8641DHX1000NE uses a 1023-pin Hi-CTE flip-chip ceramic ball grid array (FC-CBGA) package, as documented in Section 16 "Package" and the Overview section. The package has a 35 × 35 mm body size and 1.0 mm ball pitch, requiring controlled solder reflow and underfill for reliable mounting in vibration-prone environments.

Is Serial RapidIO support available on MC8641DHX1000NE?

Yes, MC8641DHX1000NE includes a Serial RapidIO 1.2 interface supporting both 1x and 4x LP-Serial link configurations at 1.25/2.5/3.125 Gbaud per lane. This is confirmed in Section 1.1 "Key Features" and Figure 1, where the "AND 1x/4x SRIO (2.5 GB/s)" block is shown adjacent to the e600 core block - a feature retained across all MPC8641 variants including the single-core MC8641DHX1000NE.
