    CHANDLER, Ariz.--(BUSINESS WIRE)--Jan. 17, 2005--

Expanders Simplify Microcontroller-Based System Upgrades and Reduce Design Cycle Time
    Microchip Technology Inc. (NASDAQ: MCHP), a leading provider of microcontroller and analog semiconductors, today introduced two 8-bit input/output (I/O) expanders.
    The MCP23008 is the only I/O expander that supports standard (100 kHz), fast (400 kHz) and high-speed (up to 1.7 MHz) I2C(TM) communications. The MCP23S08 is the only I/O expander that features SPI(TM) clock speeds up to 10 MHz.
    These unique solutions make it easy and cost-effective for designers to upgrade or enhance their current microcontroller-based systems with additional I/O requirements. The MCP23008 and MCP23S08 provide system I/O expansion via existing microcontroller serial ports, saving development time and cost by eliminating the need to redesign the complete system with a higher I/O microcontroller. The devices can support a broad range of applications with low- and high-bandwidth requirements. Hardware-address pins allow cascading of multiple devices in one system -- up to 64 bits of I/O can be added to existing systems, providing lots of design flexibility.
    Samples and volume production are available today. Packaging is lead(Pb)-free, including 18-pin PDIP, 18-pin SOIC and 20-pin SSOP options. The MCP23008 is priced at $0.75 each in 1,000-unit quantities for the 18-pin PDIP. The MCP23S08 is priced at $0.80 each in 1,000-unit quantities for the 18-pin PDIP.
