UR6HCPS2-SP40

PS2AdaptTM UR6HCPS2-SP40 Converts PS/2 Data to Serial or SPI HID & SYSTEM MANAGEMENT PRODUCTS, PROTOCOL INTERPRETER FAMILY DESCRIPTION The PS2Adapt is a Zero-Power protocol interpreter that can link an AT/PS/2-compatible Human Input Device (HID), such as a keyboard, mouse, bar-code reader, etc. to any host system equipped with either Asynchronous Serial Interface (ASI) or the Serial Peripheral Interface (SPI). TM TM FEATURES Typically consumes less than 1 µA Interfaces the host system via either Asynchronous Serial Interface or Serial Peripheral Interface (SPI) Jumper selectable interface and Baud rate Offers four PS/2 ports for the hotplug connection of external keyboards or mice including MouseWheel, 5 button mice and absolute mode touch screens APPLICATIONS H/PCs Web Phones PIN ASSIGNMENTS PDAs System Legacy Support Easy to use, one way communication protocol Operating voltage between 3 and 5 Volts Custom versions available in small or large quantities Small 7x7 mm package to accommodate slim designs The IC was designed specifically for RISC-based portable devices that are limited to ASI and SPI interfaces. The PS2AdaptTM allows designers to easily connect PS/2 devices to their system. The UR6HCPS2-SP40 emulates all the functions of the 8042 keyboard controller which typically resides on the AT/PS/2 motherboard. The Zero-PowerTM PS2AdaptTM will power down even between key presses and bewteen mouse reports. Typical power consumption is only 1 µA op...
