UR5HCFJ8-FN

LapCoderTM UR5HCFJ8 Low-Power Keyboard Encoder for Portable Systems HID & SYSTEM MANAGEMENT PRODUCTS, KEYCODERTM FAMILY DESCRIPTION The LapCoder is a versatile, lowpower keyboard encoder for portable systems. The UR5HCFJ8 provides two bi-directional channels for communication with a BIOScompatible system as well as any optional keyboard-compatible devices, such as a 101/102 desktop keyboard. TM FEATURES • Interfaces the Fujitsu FKB7211 or other similar laptop/notebook keyboards to a BIOS-compatible systems • AT / PS/2-compatible • Interfaces an external keyboard / keypad or other 8042-compatible devices • Low-power, single IC suitable for 3V battery-operated systems • Implements all functions of an 101/102 keyboard with only 82-keys • Available in DIP, PLCC and Quad Flat packages • Custom versions available in small or large quantities The UR5HCFJ8 fully supports the IBM standard keyboard communication protocol; each key press generates one of the scan codes designated in the IBM Technical Reference Manuals. The keyboard encoder handles the scanning, debounce, and encoding of 82 keys organized on an 8x16 matrix and supports embedded numeric keypad functions as well as alternate scan codes for specific keys, so that a keyboard with only 82 keys is able to emulate the functionality of a 101/102 keyboard. In addition to the system’s keyboard communication port the UR5HCFJ8 provides a fully functional keyboard input port that can be used by a standard 82/101/102 keyboard or another 8042-compatible device, such as an external numeric keypad, an OCR, or a bar-code reader. Input from both the matrix and the external device is multiplexed and presented to the system as if it were coming from a single source. The features of UR5HCFJ8 make it ideal for use in PC/AT/PS/2 laptop/notebook designs that utilize the Fujitsu FKB7211 low-profile, fulltravel membrane keyboard.

These are the Keyboard Encoder, the Mode Control Unit, the PC Communication Channel, the Data Buffer, the Interrupt Control and the 8042 Emulation Channel. All sections communicate with each other and operate concurrently. KEYBOARD ENCODER The controller continuously scans a keyboard organized as an 8 row by 16 column matrix for a maximum of 128 keys. Smaller-size keyboards are supported provided that all unused row lines are pulled to Vcc. The IC selects 1 of the 16 column lines (C0-C15) every 512 mS and then reads the row data lines (R0R7). 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 Communication Channel.

Note: An underscore before a pin mnemonic denotes an active low signal. Switch Matrix Encoding Each matrix location is programmed to represent either a single key or a key combination of the IBM 101/102 standard keyboard. Scan Code Table Sets The UR5HCFJ8 supports all three scan code table sets. Scan Code Sets 1 and 2 are the default sets for AT/PS/2 systems. Scan Code Table Set 3 allows the user to program individual key attributes such as Make/Break and Typematic or Single-Touch Action. For more information, refer to the IBM Technical Reference Manuals.

Embedded Numeric Keypad The UR5HCFJ8 implements an embedded numeric keypad. The Numeric Keypad Function is invoked by pressing the Num Lock Key. N-Key Rollover 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. If a key is defined to be Typematic, the corresponding code(s) will be transmitted while that key is held pressed. When the 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 to the number of keys that can be held pressed at the same time. However, two or more key closures, occurring within a time interval of less than 5 mS, will set an error flag and will not be processed. This procedure protects against the effects of accidental key presses. FN Key A special FN Key has been implemented to perform the following functions while it is held pressed: • • • • Function Key F1 becomes F11 Function Key F2 becomes F12 Ctrl Left Key becomes Ctrl Right Alt Left Key becomes Alt Right “Ghost” Keys 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 Actual key presses 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 or are likely to be pressed at the same “Ghost” Key time by a fast typist (i.e., keys located in adjacent positions on the keyboard) should be placed in the same row or column of the matrix, whenever possible. Shift keys (Shift, Alt, Ctrl) should not reside in the same row (or Figure 1: “Ghost” or “Phantom” Key Problem column) with any other keys. The UR5HCFJ8 has built-in mechanisms to detect the presence of “ghost” keys, thus eliminating the necessity of external hardware. If Num Lock is set: • 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 interfacing 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). They are set by the system (AT/PS/2 protocol).

Two lines, KC and KD, provide bi-directional clock and data signals. In addition, the UR5HCFJ8 supports all commands from and to the system, as described in the IBM Technical Reference Manuals. The following table shows the commands that the system may send and their values in hex. Command Set/Reset Status Indicators Echo Invalid Command Select Alternate Scan Codes Invalid Command Read ID Set Typematic Rate/Delay Enable Default Disable Hex Value ED EE EF F0 F1 F2 F3 F4 F5 F6 F7 F8 F9 FA FB FC FD FE Command Key Detection Error/Overrun Keyboard ID BAT Completion Code BAT Failure Code Echo Acknowledge (Ack) Resend Key Detection Error/Overrun Hex Value 00* 83AB AA FC EE FA FE FF** Hot Plug-Ins of External Device The UR5HCFJ8 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 keyboard. After communication has been established, the encoder will continue to check for the presence of the external keyboard. 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 reinitiate 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. *Code Sets 2 and 3 **Code Set 1 Table 3: Keyboard Commands to the System (AT/PS/2 protocol) 8042 Emulation Channel The UR5HCFJ8 fully emulates a system’s keyboard port, available to a standard 82/101/102 external keyboard or other 8042-compatible device. Communication with a keyboard-compatible device is accomplished by clock and data lines via EKC and EKD pins, respectively. A third pin, EKC1, connects to the Clock Line and interrupts the controller whenever the external device initiates a communication session. 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. After they are acknowledged, commands and data from the system are transmitted to the external device. Shift Status LEDs 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 in both keyboards. The LED status indicators are properly set after every new connection of an external keyboard. Set Default Set All Keys Typematic Make/Break Make Typematic/Make/Break Set Key Type Typematic Make/Break Make Resend Reset FF Table 2: Keyboard Commands from the System (AT/PS/2 protocol) These commands are supported in the AT/PS/2 protocol and can be sent to the keyboard at any time.The following table shows the commands that the keyboard may send to the system.

The Built-in Oscillator on the UR5HCFJ8 requires the attachment of the 4.00 MHz Ceramic Resonators with built-in Load Capacitors.. You can use either an AVX, part number PBRC-1.00 BR; or a Murata part number CSTCC4.00MG ceramic resonator. It may also be possible to operate with the 4.00 MHz Crystal, albeit with reduced performance. Due to their high Q, the Crystal oscillator circuits start-up slowly. Since the LapCoderTM constantly switches the clock on and off, it is important that the Ceramic Resonator is used (it starts up much quicker than the Crystal). Resonators are also less expensive than Crystals. Also, if Crystal is attached, two Load Capacitors (33pF to 47pF) should be added, a Capacitor between each side of the Crystal and ground. In both cases, using Ceramic Resonator with built-in Load Capacitors, or Crystal with external Load Capacitors, a feedback Resistor of 1 Meg should be connected between OSCin and OSCout. Troubleshoot the circuit by looking at the Output pin of the Oscillator. If the voltage it half-way between Supply and Ground (while the Oscillator should be running) --- the problem is with the Load Caps / Crystal. If the voltage it all the way at Supply or Ground (while the Oscillator should be running) --there are shorts on the PCB. NOTE: when the Oscillator is intentionally turned OFF, the voltage on the Output pin of the Oscillator is High (at the Supply rail).
