MosChip styles its SoCs as "NAPs" (network appliance processors), though that is not an acronym we expect to gain widespread traction. The MCS8142 targets consumer-grade network attached storage (NAS) devices, PC and media docking stations, home networking, and media servers. Meanwhile, the MCS8144 adds a display controller, and targets digital signage, in addition to the above applications. Both are fabricated using 130nm process technology.
Touted as "second-generation," the chips are based on ARM9 cores clocked at 550MHz. They use an interconnect touted as offering a "point-to-point" link to each device on the system bus. An on-chip memory controller supports DDR2 RAM. There's also a dedicated TCP/IP/UDP engine, and a "dual-mode" PCI Express interface, according to the company.
MCS8142
The MCS8142, supplied in a 256-pin TFBGA (thin fine pitch ball grid array) package, includes the following functionality in addition to its CPU, according to MosChip:Gigabit Ethernet port
Integrated DDR2 memory controller
16C550-compatible UART
1 x1 PCI Express port
I2C
SPI
8 GPIOs

MCS8144
The MCS8144, which comes in a 292-pin TFBGA package, may be interfaced to LVDS flat panels directly, and may additionally be connected to TFT/STN displays and TV monitors, with resolutions ranging from QVGA (320 x 240 pixels) to WXGA (1280 x 800 pixels). Compared to the MCS8142, the MSC8144 also adds a second x1 PCI Express port, according to MosChip (see block diagram, below).
