SK5210-LP SK5210 Keyboard Encoder ICs LQFP48 USB and HID over I2C Dual Interface Keyboard Controller

SK5210 USB and HID over I2C Dual Interface User Programmable FlexMatrix™ Keyboard Encoder
with 1 external PS/2, 1 PWM Backlight and 7 LEDs Control, Field-Upgradable Bootloader

Specification: SK5210 Keyboard Encoder ICs

Description:

The SK5210 is a low power USB and I2C dual interface keyboard encoder with 1 PWM backlight and 7 LEDs control. While the USB interface is connected to the main PC as normal keyboard, the secondary I2C interface can be used to communicate with a system embedded controller (EC) for EC to receive all user events and get full control of the system. It’s the best choice for customized keyboard design for tablet / PC / laptop / docking station / Instrument.

The SK5210 scans and encodes an 8-row by 20-column matrix. The key press events are translated to keyboard report. The encoder gets matrix information from on-chip matrix tables.

The backlight LED PWM brightness control and 7 LEDs can be controlled via the dual interfaces by commands or key press events.

The SK5210 provides an external PS/2 port that supports hot plug and hot swap of PS/2 devices such as touchpad, pointing stick, mouse including wheel mice, and keyboard. The host can send commands via SK5210 PS/2 command relay feature to the external PS/2 device to change default settings.

Applications:

▪ Notebook PCs
▪ Desktop PCs
▪ Tablet PCs
▪ Tablet/Mobile Phone docking station
