UR6HCPS2-SP40

The PS2AdaptTM UR6HCPS2-SP40 is a Zero-PowerTM 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).

The IC UR6HCPS2-SP40 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 A operating between 3-5 Volts.

The UR6HCPS2-SP40 boasts 4 external PS/2 ports that support the hot-plug connection of an external PS/2 keyboard or mouse, including MouseWheel, 5-button mice and touch screens in absolute mode.

Each of four external PS/2 ports also support more than 140 key scan codes including international language keys, internet keys, and power keys. The PS2AdaptTM UR6HCPS2-SP40 also offers 4 reserved pins for LED functions, their functions can be customized by Semtech.
