MCS8142
The MosChip MCS8142 is a highly integrated and advanced RISC network appliance processor that can be used in a variety of products that require network connectivity. The CPU subsystem of the MCS8142 consists of a 525MHz, 32-bit ARM Compatible RISC microprocessor
Gigabit Networking Speeds (10/100/1000) are supported by the MCS8142, this solution contains a media access controller (MAC) and is fully compliant with IEE802.3 specificationss
Additionally, the MCS8142 network processor contains two USB 2.0 Compliant Host Ports. One of the ports can be configured as an OTG port. These ports have been designed to connect a wide range of USB-based devices to an Ethernet network (Internet or Intranet).
The PCI Express (PCIe) interface supported by the MCS8142 is fully compliant with PCI Express Base specifications, Revision 1.1. One x 1 Lane PCI Express Port is supported enabling connectivity to a variety of PCI Express devices such as 802.11x peripherals, Audio Controllers, PCI Express -SATA and PCI Express -IDE controllers.
A 32 Bit, 262.5 MHz DDR2 SDRAM Memory Controller is supported by the MCS8142 that enables up to 1.5GB of memory space and supports On-Chip Termination.
The MCS8142 also supports a 16C550 compatible UART, I2C Interface complaint with Version 2.1, SPI Interface compliant with industry standard specifications and various power management modes.
