SMSC Introduces the LPC47M15x Advanced I/O Controller for Desktop PCs.

Business/Technology Editors

HAUPPAUGE, N.Y.--(BUSINESS WIRE)--Aug. 7, 2001

Standard Microsystems Corporation (Nasdaq: SMSC) today announced the availability of its latest Advanced I/O (Input/Output) Controller, the LPC47M15x I/O Controller with Hardware Monitoring Capability.

The voltage and temperature monitoring capability of the LPC47M15x with best-in-class accuracy, along with the fan speed detection and control feature, enable the environmental control necessary in today's high-speed, high-heat, small form factor PCs. The LPC47M15x's integration of hardware monitoring capability with complete legacy I/O functionality in a single 128 pin device also assists in reducing the mainboard design's overall bill-of-materials and system cost while maximizing efficient use of board space.

The LPC47M15x is the latest member of SMSC's family of compatible Advanced Desktop I/O Controllers. Each device in this family of parts - comprised of the LPC47M15x, the LPC47M13x, which offers complete I/O functionality, and the LPC47M14x, which additionally includes an integrated USB Hub - maintain functional and pin compatibility of the I/O section. This unique pin compatibility architecture enables the use of a common chip layout, easing design efforts and providing additional flexibility of design through option selection at the chip level.

The LPC47M15x is a 3.3V, LPC-compatible device, which includes an 8042-based keyboard controller, a floppy disk controller with enhanced digital data separator, serial and parallel ports, and infrared support. System control functionality includes an IRQ interface and ACPI embedded controller interface, general purpose I/O pins, fan control with two tachometers and independently programmable pulse width modulators, maskable hardware wake-up events, and a System Management Bus (SMBus) interface.

The LPC47M15x's hardware monitoring capability includes monitoring of seven external analog inputs for monitoring the most common and critical PC voltages - +1.5V, +1.8V, +2.5V, +3.3V, +5V, +12V and Vccp (core processor voltage) - plus internal monitoring of the part's own HVCC or HVSB. The voltage monitoring pins are dedicated to their respective voltages and require no external components for scaling or similar treatment. The LPC47M15x also supports temperature monitoring with inputs for two external thermal diodes, as well as an internal sensor to measure ambient temperature. High and low temperature and voltage ranges are user-selectable and out-of-limit conditions create system alerts by using well established and industry standard system interrupt techniques.

Robert Hollingsworth, Standard Microsystems' Senior Vice President, Sales and Marketing, Advanced I/O Products, stated, "SMSC is meeting the needs dictated by tomorrow's PC designs by continuing to offer the most integrated desktop controllers available. I am convinced that SMSC's concept of pin compatible devices, the high degree of integration of the LPC47M15x, and the world class accuracy of its monitoring capability will lead to winning major designs with this product."

Price, Package and Availability

The LPC47M15x is packaged in an industry standard 128-pin quad flat pack (QFP) package and is priced at $5.50 in production volume.

Samples of the LPC47M15x are available immediately. SMSC also provides a full suite of demonstration and development tools - documentation, evaluation boards and utility software -as well as world-class field application engineering support.

The LPC47M15x data sheet, as well as technical information on SMSC's other products, is available on SMSC's web site at http://www.smsc.com. Please contact your local SMSC sales office for more information.
