POWER MANAGEMENT SH2165 supports suspend command remote wake-up feature. suspend state, SH2165 still runs normally, consuming about because PixiPoint sampling circuit must continuously. This does comply with specification, which requires power consumption under when suspended. host system still other related circuits into power consumption mode. When SH2165 gets keyboard report PixiPoint report, wakes host. Windows supports "selective suspend", which works very well with SH2165. Windows does normally turn "selective suspend" composite device like SH2165. Semtech provides driver initialization file (smtchid.inf) enable "selective suspend" SH2165 under Windows enable "selective suspend" SH2165 under Windows take following steps: Connect SH2165 host system. Windows Control Panel System Hardware Manager Under Human Interface Devices, Human Interface Devices, SH2165 keyboard SH2165 mouse (force stick). Follow step each item. Right-click item, choose update driver manually choose "have disk." Then select smychid.inf file. Note: Semtech does need provide drivers. Semtech provides this driver initialization file that selective suspend feature supported SH2165, using existing Microsoft mouse keyboard drivers.

PIXIPOINT BUILT-IN FEATURES Select Double Execute Press Hold Drag EasyDrag- reduces speed cursor when user dragging object desktop, making simple accurately handle object CleanStop- ensures that cursor stops precisely
PIXIPOINT SIGNAL CONDITIONING CIRCUIT PixiPoint interfaces with sensor that four strain gauges each sides. force applied precisely direction, produces change resistance only gauges. Force direction causes changes only gauges. pair gauges increases, while other decreases resistance. user presses sensor from axis), strain gauges decrease resistance. When test current passed through gauges, these resistance changes converted into voltage changes. These signals very small, typically under Full Scale. signal conditioning circuit balances amplifies incoming signals digitizing built-in converter. Semtech's circuit correct significant imbalance between gauges each pair 25%), allowing relaxed manufacturing tolerances sensors cabling. There performance degradation over full operating temperature range, degradation large temperature gradients between paired gauges. LEDS BACKLIGHT SH2165 supports keyboard backlight four LEDs: Lock, Caps Lock, Scroll Lock, Katakana Lock. Katakana Lock also serves emergency signal. Three special keys defined keyboard matrix that affect backlight LEDs. When backlight increment (BLINC) pressed, SH2165 cycles through backlight states, from backlight (the default starting state), half intensity, full intensity, off, When blackout (BLKOUT) pressed, backlight LEDs turned off; when pressed again, backlight LEDs returned their former state. (Note that blackout affects external lights only; does affect internal state operation keyboard; example, turns Lock LED, does affect Lock state.) When emergency (ALERT) pressed, emergency (the Katakana Lock LED) turns seconds, then turns off. pins BKLTOFF BKLT100 (pins control backlight circuit. backlight used, leave these pins floating.

FUNCTION MODE SH2165 includes single-byte register function mode. There three function modes: simple, sticky lock. (Note that this section, function combination left right function keys.) simple mode (the default), function-key-down state turns when function pressed, turns when function released. other words, function state always changes according this scenario: Function-key-down state Function pressed Function-key-down state turns more other keys pressed Function released Function-key-down state turns sticky mode, function-key-down state persist after function released, terminates after another pressed. Function state changes according these scenarios: Function-key-down state Function pressed Function-key-down state turns more other keys pressed Function released Function-key-down state turns Function-key-down state Function pressed Function-key-down state other keys pressed) Function released Another pressed Function-key-down state turns Function-key-down state Function pressed Function-key-down state turns other keys pressed) Function released Function pressed more other keys pressed Function released Function-key-down state turns

KEYBOARD SCANNER SH2165 scans keyboard organized column matrix maximum keys. Smaller size matrixes accommodated leaving unused pins open. SH2165 provides internal pull-ups input pins. When active, encoder selects each column line (C00C17); each column selected, reads data lines (R0-R7). closure detected zero corresponding position matrix. Each found pressed debounced period Once verified, corresponding code(s) loaded into transmit buffer serial communication channel. "GHOST" ELIMINATION scanned contact switch matrix, whenever three keys defining rectangle switch matrix pressed same time, fourth positioned fourth corner rectangle sensed being pressed. This known "ghost" "phantom" problem. Although problem cannot totally eliminated without using external Actual presses hardware, there methods neutralize negative effects most practical applications. Keys that intended used combinations should placed same "Ghost" column matrix, whenever possible. Shift-type keys (Shift, Alt, Ctrl, Window) should reside same column) keys other type. SH2165 built-in mechanisms detect reject most "ghost" keys.

KEYBOARD MATRIX DESIGN following factors must considered when designing keyboard matrix. Because "ghost" problem described previous section, shift-type keys should treated carefully when designing matrix. Shift-type keys keys that held down while other keys pressed: Shift, Alt, Control, GUI), Function. Some columns rows) should aside shift-type keys only, shift-type keys should assigned those columns rows). Cases where shift-type keys share column should kept minimum. possible, shift-type keys should share column with each other unless their function same, they very unlikely used together, both. example, this diagram standard matrix Fujitsu FKB7654 laptop-type keyboard. shift-type keys assigned columns only shift-type keys assigned those columns. There only four cases where shift-type keys share column, only keys each case, seven keys total: Function Left Right Left column Right Control Left Control column

CIRCUIT NOTES Power Circuit SH2165 reference design uses SC1453 regulator, which recommended. low-noise regulator with output voltage used. Operational amplifier Only LMV321 from Fairchild, National Semiconductor, Texas Instruments have been tested approved. Integration circuit integration capacitor greater capacitance would reduce axis sampling gain. capacitor used adjust speed senitivity. sensitivity also adjusted itself changing value R13. Backlight circuit backlight used, leave backlight control pins (BKLTOFF BKLT100, pins floating. interface circuit When SH2165 used hot-pluggable environment, recommend protection chip like Semtech's STF203-33 interface, shown evaluation board schematic. When SH2165 built product, protection port necessary, customer omit protection chip resistors capacitors instead, shown diagram below.
