Description
The typical usage model is to locate the ECE1119/ECE1117 in the keyboard assembly. By mounting theECE1119/ECE1117 onto the keyboard assembly, thekeyboard signals as well as the touchpad/point stickPS/2 signals and the backlight PWMs are routed fromthe keyboard to the motherboard over a single BC-Linkconnection. In all other notebook designs without BCcompanion device, the keyboard matrix signals, as wellas, PS/2 and LEDs are routed to the motherboard via awide ribbon extension for the keyboard switch circuit.
The ECE1119 communicates to the upstream host viaBC-Link or SMBus and provides up to three down-stream BC-Link or SMBus ports to permit communica-tion between the upstream host and downstreamcompanion devices.
The ECE1119/ECE1117 has a single Power SourceVCC and a single digital ground VSS. There are twopower domains VCC and VCC_1.8.

Most Current Data SheetTo obtain the most up-to-date version of this data sheet, please register at our Worldwide Web site at:
http://www.microchip.com
You can determine the version of a data sheet by examining its literature number found on the bottom outside corner of any page. The last character of the literature number is the version number, (e.g., DS30000000A is version A of document DS30000000).
ErrataAn errata sheet, describing minor operational differences from the data sheet and recommended workarounds, may exist for cur-rent devices. As device/documentation issues become known to us, we will publish an errata sheet. The errata will specify therevision of silicon and revision of document to which it applies.
To determine if an errata sheet exists for a particular device, please check with one of the following:• Microchip’s Worldwide Web site; http://www.microchip.com• Your local Microchip sales office (see last page)
When contacting a sales office, please specify which device, revision of silicon and data sheet (include -literature number) you areusing.
