Functional Description Pin Definitions The USAR GreenCoderTM consists functionally of seven major sections (see Functional Diagram, previous page). These are the Keyboard Encoder, a 16-Bit Timer, the Mode Control Unit, the Data Buffer, the Interrupt Control, the PC Communication Channel and the 8042 Emulation Channel. All sections communicate with each other and operate concurrently.

Smaller-size keyboards are supported provided that all unused row lines are pulled to Vcc. When active, the encoder selects 1 of the 16 column lines (C0-C15) every 512 µS and then reads the row data lines (R0-R7). A key closure is detected as a 0 in the corresponding position of the matrix. A complete scan cycle for the entire keyboard takes approximately 9.2 mS. 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 of the PC keyboard communication channel.

Keyboard Encoder, Cont. Mode Control Embedded Numeric Keypad N-Key Rollover The USAR GreenCoderTM implements an embedded numeric keypad. The Numeric Keypad Function is invoked by pressing the Num Lock Key. In this mode, the code(s) corresponding to each key press are transmitted to the host system as soon as that key is debounced, independently of the release of other keys. FN Key A special FN Key has been implemented to perform the following functions while it is held pressed: • Function Key F1 becomes F11 If a key is defined to be Typematic, the corresponding make code(s) will be transmitted while the key is held pressed. When a key is released, the corresponding break code(s) are then transmitted to the host system. If the released key happens to be the most recently pressed, then Typematic action is terminated. There is no limitation in the number of keys that can be held pressed at the same time. However, two or more key closures, occurring within a time interval less than 5 mS, will set an error flag and will not be processed. This procedure protects against effects of accidental key presses. “Ghost” Keys • Function Key F2 becomes F12 • Control Left Key becomes Ctrl Right • Embedded numeric keypad keys become regular keys If Num Lock is not set: • Embedded numeric keypad keys provide the same codes as a numeric keypad when the Num Lock is not set (Arrow keys, PgUp, PgDn, etc.) Status LED indicators The controller provides an interface for three LED shift status indicators. All three pins are active low to indicate the status of the host system (Num Lock, Caps Lock and Scroll Lock) and are set by the system. After approximately a one-minute period of keyboard inactivity, LEDs are dimmed to conserve power. They are set to full brightness again upon a new keystroke. USAR Datasheet In any scanned contact switch matrix, whenever three keys defining a rectangle on the switch matrix are held 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 Actual key presses to be used in combinations or are likely to be pressed at the same time by a fast typist (i.e., keys located in adjacent positions on the keyboard) should be placed in the same row or “Ghost” column of the matrix whenever Key possible. Shift Keys (Shift, Alt, Ctrl) should not reside in the same row (or column) with any other keys. The USAR GreenCoderTM has built-in mechanisms to detect the presence Figure 1: “Ghost” or “Phantom” Key Problem of a “ghost” key, thus eliminating the necessity of external hardware. DOC5-FJL-DS-104 4 USAR GreenCoderTM UR5HCFJL USAR KeyCoderTM family product specifications USAR Systems Inc. 8042 Emulation Channel Special Handling The USAR GreenCoderTM fully emulates a system’s keyboard port, available to a standard 84/85/101/102 external keyboard or other 8042-compatible device. Communication with a keyboardcompatible device is accomplished by clock and data lines via EKC and EKD pins, respectively. A third pin, EKC1 that connects to the Clock Line, interrupts the controller whenever the external device initiates a communication session. Connection of External Device The UR5HCFJL will detect the presence of an external device. If an external keyboard or other device was not connected during power-on and is connected at a later time, the encoder will proceed with the normal reset routine in order to properly initialize the external device. After communication has been established, the encoder will continue to check for the presence of the external device. While the external device is connected, the encoder will not enter the sleep mode. If the device is disconnected at a later time, the encoder will become aware of it. If a subsequent connection takes place, the controller will re-initiate a reset sequence. This unique feature allows the user to connect or disconnect an external device at any time without having to reset the system. When power is first applied, the controller proceeds with the standard reset sequence with the external device. Data and commands initiated from the external device are buffered in the controller’s FIFO along with data from the scanned matrix, and then are presented to the system as if they were coming from a single source. Once they are acknowledged, commands and data from the system are then transmitted to the external device. Shift Status LEDs USAR Datasheet DOC5-FJL-DS-104 Shift Status LEDs (Num Lock, Caps Lock and Scroll Lock) indicate the status of the system and are controlled by commands sent from the system. Set/Reset Status Indicator Commands from the system will be executed both by the external keyboard and the scanned matrix. For example, if the user presses the Caps Lock Key on either keyboard, the Caps Lock LED will be affected on both keyboards. The LED status indicators are properly set after each new connection of an external keyboard. 5 USAR GreenCoderTM UR5HCFJL USAR KeyCoderTM family product specifications USAR Systems Inc. PC Communication The UR5HCFJL implements all the standard functions of communication with a BIOScompatible PC/XT or AT/PS/2 host system. Two lines, KC and KD, provide bi-directional clock and data signals. In addition, the UR5HCFJL supports all commands from and to the system, as described in the IBM Technical Reference Manuals. The following table shows the commands that the keyboard may send to the system. The following table shows the commands that the system may send and their values in hex.

Presence or absence of an external device will not effect the normal operation of the USAR GreenCoderTM. These commands are supported in the AT/PS/2 protocol and can be sent to the keyboard at any time.

States of Operation Using the GreenCoderTM for System Management Tasks The USAR GreenCoderTM has three states of operation, implemented to minimize the power consumption of the keyboard subsystem. The following diagram illustrates the three states of operation of the GreenCoderTM. The USAR GreenCoderTM provides an ideal complement to low-power chip sets targeted to the portable and mobile computing market. The Green CoderTM can be used to handle several system management tasks for small, portable system designs, thus saving space and additional components for the System Designer. Such system management tasks include those listed below. STAND BY STATE SLEEP STATE However, since most of the system management tasks are application and hardware-dependent, detailed implementation information is outside the scope of this document. For application examples and sample schematics, contact USAR Systems Technical Support. System shut-down/wake-up signal ACTIVE STATE Figure 2: States of Operation of UR5HCFJL The USAR GreenCoderTM can provide the system power management unit with a shut-down/wake-up signal which can be invoked either by a special keyboard combination or after a programmed period of user inactivity. Most of the time, the USAR GreenCoderTM is in the Sleep State. Power consumption in this state is approximately 2 µA at 5 Volts of operation. The GreenCoderTM enters the Active State only when there is an event to process, such as a keystroke, a command from the system, or data from the external PS/2-compatible device. The USAR GreenCoderTM enters and stays in the Stand-By State if an external device is connected to the auxiliary port or if one or more LEDs are turned on. In the Stand-By State, the IC consumes approximately 600 µA at 5 Volts. Transition from one state to the other does not require any input from the system. Note: Self-Power ManagementTM is a feature protected under USAR Systems’ patent and copyright rights. Purchase of any version of the UR5HCFJL encoder conveys a license to utilize the Self-Power Management feature only through use of the UR5HCFJL in a PS/2-compatible keyboard subsystem.
