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.

FUNCTION BLOCK DESCRIPTION

The SK5210 consists functionally of several major sections (see the block diagram on the previous page). These include power on reset, oscillator circuit, 16-bit timer, power management, programming interface, keyboard scan, keyboard LEDs, backlight brightness control, matrix data block, USB keyboard interface, I2C keyboard interface, external PS/2 interface. All sections communicate with each other and operate concurrently.

Keyboard Scan

The SK5210 scans a keyboard organized as an 8 row by 20 column matrix for a maximum of 160 keys. Smaller size matrixes can be accommodated by leaving unused pins open. The IC provides internal pull-ups for the row input pins. When active, the encoder selects each column line (C0-C19); for each column selected, it reads the row data lines (R0-R7). A key closure is detected as a zero in the corresponding position of the matrix.

Each key found pressed is debounced for a period of 20 ms. Once the key is verified, the corresponding key code(s) are loaded into the transmit buffer.

In any scanned contact switch matrix, whenever three keys defining a rectangle on the switch matrix are pressed at the same time, a fourth key positioned on the fourth corner of the rectangle is sensed as being pressed. This is known as the “ghost” or “phantom” key problem.

Although the problem cannot be totally eliminated without using external hardware, there are methods to neutralize its negative effects for most practical applications. Keys that are intended to be used in combinations should be placed in the same row or column of the matrix, whenever possible. Shift keys (Shift, Alt, Ctrl, Window, Fn) should not reside in the same row (or column) as any other keys. The SK5210 has built-in mechanisms to detect and reject “ghost” keys.

Notes: Column 16 to 19 pins are shared with LED1 to LED4. They can be configured to be either LED functions or column functions. At default, they are configured as column function.

Pin# LED Function Name Keyboard Scan Function Name

13 LED1 C16

14 LED2 C17

15 LED3 C19

16 LED4 C18

When a key event is detected, it will be reported to both USB interface and HID over I2C interface. The key event can be either enabled or disabled for each interface.

Keyboard LEDs

The SK5210 provides 7 pins to directly drive LEDs for CapsLock, Numlock, Scrolllock, Fnlock functions and general LED indicators.

USB Interface

The SK5210 follows USB.org’s Universal Serial Bus Specification 2.0 and Device Class Definition for HID 1.11 as a full speed HID keyboard device.



HID over I2C Interface

The SK5210 follows Microsoft’s HID Over I2C Protocol Specification – Device Side Version 1.00 as a HID over I2C keyboard and mouse combo device.

nINT pin can be configured to low assertion or high assertion. nINT high assertion is default.

Power Management

When USB interface is connected, the SK5210 supports selective suspend and remote wake up to get maximum power saving.

The host embedded controller can instruct the SK5210 to connect/disconnect USB interface to save power.

Backlight Brightness Control

The 10-bit PWM output controls the brightness of backlight circuit. The PWM clock is sourced from 12MHz clock, and the parameters such as period, positive width are programmable.

Power On Reset Circuit

The SK5210 has built-in power on reset circuit with simple external RC components.

Oscillator Circuit

The SK5210 has built-in oscillator circuit and no external crystal or resonator is needed.

16-bit Timer

The 16-bit timer provides the timing control for USB and I2C communication, keyboard scan and sleep timer wakeup.

External PS/2 Port

The SK5210 provides an external PS/2 port that supports hot plug and hot swap of PS/2 mouse including wheel mouse, and keyboard devices.

Matrix Data Block

The SK5210 provides an on-chip data block to store keyboard matrix, scan code mapping table and etc. The matrix data block is pre-defined and cannot be changed in the field. Custom matrix data block can be done via Sprintek custom keyboard service.

Programming Interface

The programming interface is reserved for Sprintek to programming new firmware. PRGC and PRGD pins are recommended to be connected to a 6 pin header in the schematic. The header needn’t be populated in the final assembly. Three test points are preferred if 6 pin header is not allowed due to space reason.



I2C COMMAND PROTOCOL

I2C Slave Device Address

The 7-bit address of the device is shown as below 0x39. After combined with R/W bit, the 8-bit address is 0x72 for I2C write operation, 0x73 for I2C read operation.

Command and Data Register

The HID over I2C spec requires that all devices respond to certain commands. The commands are issued to the command register. The command is an opcode as defined by the HID over I2C spec. The operand for the command goes to the data register. Below is a list of commands supported by the SK5210.

Op Code Command Name Effective on Device

0001b RESET Device is reset and all registers are returned to default value. This command has the same effect on the device as a power on reset.

0010b GET_REPORT Most recent input report is transferred to Data Register

0011b SET_REPORT Data register contents are used to turn on/off LED.

1000b SET_POWER All LEDs are turned off, USB interface is shut down and disconnected from USB bus, and device is in lowest current mode (will still detect key presses)



KEYBOARD MATRIX DESIGN

Four Keyboard Matrix

The SK5210 supports four 8X20 keyboard matrixes for the following cases: LFn off/on, RFn off/on.

Design Keyboard Matrix

Please refer to Microsoft Windows Platform Design Notes “Keyboard Scan Code Specification” to get more information.

Create Keyboard Matrix

The FlexMatrix Editor program enables the user to create keyboard matrix including macro key definition and function key definition, then save them in binary format.

The Editor program allows the user to assign a logical key to any position in the 8 x 20 matrix. Once a matrix has been created, it is saved in a binary file. The file can be downloaded to the SK5210 flash data block via FlexMatrix Programmer software.

The Editor program can be downloaded from http://sprintek.com/support/Downloads.aspx. Here is the screen snapshot of FlexMatrix Editor software.

DEFAULT KEYBOARD MATRIX

The following table shows the default keyboard matrix on chip. Please fill out this table and send it to Sprintek for customized design.

Matrix0 and Matrix1(LFn Off)

The following are key matrix0 and matrix1 tables when LFn is off. Matrix0 – RFn is off and LFn is off; Matrix1 – RFn is on and LFn is off. When a single key definition in the table, it will work for RFn off case only. For example, location (C1, R2) “A” will works for matrix 0; but not in matrix1. When double keys are defined in the table, key in the upper side is for matrix 0 and key in the lower side is for matrix 1. For examples, Location (C12,R7) “F10 / Scroll Lock”, when RFn is off, “F10” is selected; when RFn is on, “Scroll Lock” is selected. R0 R1 R2 R3 R4 R5 R6 R7

SKEY is the Sprintek key number. AT-101 is the key reference number on the standard AT-101 keyboard layout, shown in the diagram below USB page is the Universal Serial Bus (USB) Human Interface Device (HID) usage page for the key. Most keys are on the keyboard page, page 0x07. For information about USB codes, see the USB HID specifications, published by the USB-IF (http://www.usb.org/). USB usage is the USB HID usage ID for the key on the specified USB HID page. PS/2 codes are the make (key press) and break (key release) codes for PS/2 scan sets 1, 2, and 3; U/A means unassigned. Note that some keys, by default, do not generate break codes, even if the break codes are shown in this table.
