SPICoderTM 06 UR5HCSPI-06 Zero-PowerTM Keyboard Encoder & Power Management IC for H/PCs SPICoder is a trademark of Semtech Corp. All other trademarks belong to their respective companies. Copyright Semtech 1997-2001 DOC5-SPI-06-DS-103 www.semtech.com 1 HID & SYSTEM MANAGEMENT PRODUCTS, H/PC IC FAMILY DESCRIPTION FEATURES • StrongARMTM Handheld PCs • Windows CE® Platforms • Web Phones • Personal Digital Assistants (PDAs) • Wearable Computers • Internet Appliance The UR5HCSPI-06 keyboard encoder and power management IC is designed specifically for handheld PCs (H/PCs). The off-the- shelf UR5HCSPI-06 will readily work with CPUs designed for Windows CE®, saving OEMs significant development time and money as well as minimizing time-to-market for the new generations of handheld products. Three main design features of the UR5HCSPI-06 make it the ideal companion for the new generation of Windows CE® -compatible, single-chip computers: low-power consumption; real estate-saving size; and special keyboard modes. “Quasi” Zero-PowerTM consumption (less than 2µA @ 3V), a must for H/PCs, provides the host system with both power management and I/O flexibility, with almost no battery drainage. Finally, special keyboard modes and built-in power management features allow the SPICoderTM 06 to operate in harmony with the power management modes of Windows CE®, resulting in more user flexibility and longer battery life. The UR5HCSPI-06 also offers programmable features for wake-up keys and general purpose I/O pins. • Special keyboard and power management modes for H/PCs, including programmable “wake- up” keys • Scans, debounces, and encodes an 8 x 14 matrix and controls discrete switches and LED indicators • Available in a small 44-pin QFP package • Custom versions available • SPI-compatible keyboard encoder and power management IC with other interfaces available • Compatible with Windows CE® keyboard specification • Zero-PowerTM — typically consuming less than 2µA, between 3-5V • Offers overall system power management capabilities • Compatible with “system-on silicon” CPUs for H/PCs 111 12 22 33 23 44 34 PWR_OK NC0 OSCO OSCI Vcc NC NC _RESET _WKU Vx C7 NC C12 C13 GIO0 _IOTEST Vss NC R7 R6 R5 R4 QFP C5 C4 C3 C2 C1 C0 R0 R1 R2 R3 R4 _PWR_OK _ATN _SS SCK MOSI MISO XSW SW0 C8 C9 C10/WUKO 40 1 6 7 12 17 18 23 28 29 34 39 PLCC APPLICATIONS PIN ASSIGNMENTS |
