Moschip Semiconductor Technology has announced a PCI Express (PCIe) controller chipset for applications such as connectivity for docking stations in media players and serial attached devices.

The MCS99XX’s connectivity controller chips provide built-in support to enable a variety of PCIe to multiple I/O connectivity options.

Further applications for this chipset include serial networking/monitoring equipment, point-of-sale (POS) terminals, parallel/printer ports, add-on serial and/or parallel I/O cards, embedded systems I/O expansions, plus industrial control, security, monitoring and PC applications.

The MCS99XX product range consists of four devices: MCS9900CV-AA, MCS9904CV-AA, MCS9901CV-CC and MCS9922CV-AA.

The core product, MCS9900, offers flexibility while the other three devices are optimised with fixed I/O configurations.

The MCS99XX features serial ports that are compatible with RS232, RS422 and RS485 standards and supports throughput from 50bps to 16Mbps.

The parallel port is compatible with IEEE 1284 and supports nibble, byte, SPP, ECP and EPP modes.

All eight GPIO pins are programmable and can be used as input or output.

An I2C interface is provided to configure MCS9900 device options through an external EEPROM.

All four MCS99XX devices provide an option for peripheral expansion through Moschip’s Cascade interface.

The generic cascade interface allows interconnecting with similar chips from Moschip, such as the MCS9950, to expand the peripheral ports.

The devices are packaged in 128-pin LQFP, RoHS.

The MCS9900 is a single-lane multifunction PCIe to I/O controller.

It supports two modes of operations that are selectable through device mode pin selects.

Mode one supports four serial and eight GPIO ports.

Mode two supports two serial, one parallel and eight GPIO ports.

The MCS9901CV-CC is hardwired to 2-serial plus 1-parallel mode.

It can be programmed to lower configurations (such as 2-serial, or 1-serial and 1-parallel, or 1-parallel) through EEPROM.

The MCS9904 is hardwired to 4-serial mode.

It can be programmed to lower configurations (such as 3-serial, 2-serial or 1-serial) through EEPROM.

The MCS9922 is hardwired to 2-serial mode.

It can be programmed to lower configurations (such as 1-serial) through EEPROM.

Recommended operating conditions are rated for a 1.2V digital or analogue power supply while the I/O supply voltage is rated at 3.3V digital or analogue power supply at 0-85C.

The parts are fully compliant with PCI Express base specification, revision 1.1.

They are offered with robust support and reference design services.

Software support for the respective devices includes: Windows 7, 32 and 64 bit; Windows 32 and 64/XP 2008 server; Windows 32, 2000/XP /2003 server and Windows 64 XP/2003 server; Windows Vista 32 and 64 bit; WinCE 5.0 and 6.0; Linux Kernel 2.6.28 and above; Mac 10.4 and above; and Windows-XP-based EEPROM, GPIO utility and diagnostics.
