APPLICATIONS Keypad entries and input/output expansion capabilities Smart phones, remote controls, and cameras Healthcare, industrial, and instrumentation GENERAL DESCRIPTION The ADP5585 is a 10 input/output port expander with a built in keypad matrix decoder, programmable logic, reset generator, and PWM generator. Input/output expander ICs are used in portable devices (phones, remote controls, and cameras) and nonportable applications (healthcare, industrial, and instrumentation). I/O expanders can be used to increase the number of I/Os available to a processor or to reduce the number of I/Os required through interface connectors for front panel designs. The ADP5585 handles all key scanning and decoding and can flag the main processor via an interrupt line that new key events have occurred. GPI changes and logic changes can also be tracked Rev. C as events via the FIFO, eliminating the need to monitor different registers for event changes. The ADP5585 is equipped with a FIFO to store up to 16 events. Events can be read back by the processor via an I2C-compatible interface. The ADP5585 frees up the main processor from having to monitor the keypad, thereby reducing power consumption and/or increasing processor bandwidth for performing other functions. The programmable logic functions allow common logic requirements to be integrated as part of the GPIO expander, thus saving board area and cost.

Internal Block Diagram Rev. C | Page 7 of 40 ADP5585 Data Sheet DEVICE ENABLE When sufficient voltage is applied to VDD and the RST pin is driven with a logic high level, the ADP5585 starts up in standby mode with all settings at default. The user can configure the device via the I2C interface. When the RST pin is low, the ADP5585 enters a reset state and all settings return to default. The RST pin features a debounce filter. If using the ADP5585ACBZ-01-R7 or ADP5585ACPZ-01-R7 device model, the RST pin acts as an extra row pin. Without a reset pin, the only method to reset the device is by bringing VDD below the UVLO threshold. DEVICE OVERVIEW The ADP5585 contains 10 multiconfigurable input/output pins. Each pin can be programmed to enable the device to carry out its various functions, as follows: • • • • • Keypad matrix decoding (five-column by five-row matrix maximum). General-purpose I/O expansion (up to 10 inputs/outputs). PWM generation. Logic function building blocks (up to three inputs and one output). Two reset generators. All 10 input/output pins have an I/O structure as shown in Figure 6. Each I/O can be pulled up with a 100 kΩ or 300 kΩ resistor or pulled down with a 300 kΩ resistor. For logic output drive, each I/O has a 5 mA PMOS source and a 10 mA NMOS sink for a pushpull type output. For open-drain output situations, the 5 mA PMOS source is not enabled. For logic input applications, each I/O can be sampled directly or, alternatively, sampled through a debounce filter. The I/O structure shown in Figure 6 allows for all GPI and GPO functions, as well as PWM and clock divide functions. For key matrix scan and decode, the scanning circuit uses the 100 kΩ or 300 kΩ resistor for pulling up keypad row pins and the 10 mA NMOS sinks for grounding keypad column pins (see the Key Scan Control section for details about key decoding). Configuration of the device is carried out by programming an array of internal registers via the I2C interface. Feedback of device status and pending interrupts can be flagged to an external processor by using the INT pin. The ADP5585 is offered with three feature sets. Table 5 lists the options that are available for each model of the ADP5585. Table 5.

See Table 4 for details. Rev. C | Page 8 of 40 Data Sheet ADP5585 FUNCTIONAL DESCRIPTION EVENT FIFO EC = 3 Before going into detail on the various ADP5585 blocks, it is important to understand the function of the event FIFO. The ADP5585 features an event FIFO that can record as many as 16 events. By default, the FIFO primarily records key events, such as key press and key release. However, it is possible to configure the general-purpose input (GPI) and logic activity to generate event information on the FIFO as well. An event count, EC[4:0], is composed of five bits and works in tandem with the FIFO so that the user knows how much of the FIFO must be read back at any given time. FIRST READ KEY 3 PRESSED KEY 3 RELEASED GPI 7 ACTIVE EC = 2 SECOND READ KEY 3 RELEASED GPI 7 ACTIVE EC = 1 THIRD READ GPI 7 ACTIVE The FIFO is composed of 16 eight-bit sections that the user accesses by reading the FIFO_x registers. The actual FIFO is not in user accessible registers until a read occurs. The FIFO can be thought of as a “first in first out” buffer that is used to fill Register 0x03 to Register 0x12. The event FIFO is made up of 16 eight-bit registers. In each register, Bits[6:0] hold the event identifier, and Bit 7 holds the event state. With seven bits, 127 different events can be identified. See Table 11 for event decoding. OVRFLOW_INT KEY EVENTS GPI EVENTS FIFO UPDATE EC[4:0] LOGIC EVENTS EVENT2[7:0] EVENT3[7:0] EVENT4[7:0] The FIFO registers (0x03 to 0x12) always point to the top of the FIFO (that is, the location of EVENT1[7:0]). If the user tries to read back from any location in a FIFO, data is always obtained from the top of that FIFO. This ensures that events can only be read back in the order in which they occurred, thus ensuring the integrity of the FIFO system. A FIFO overflow event occurs when more than 16 events are generated prior to an external processor reading a FIFO and clearing it. EVENT5[7:0] EVENT6[7:0] EVENT7[7:0] 7 6 5 4 3 2 1 0 If an overflow condition occurs, the overflow status bit is set. An interrupt is generated if overflow interrupt is enabled, signaling to the processor that more than 16 events have occurred. EVENT9[7:0] EVENT10[7:0] EVENT11[7:0] EVENT8_IDENTIFIER[6:0] EVENT12[7:0] KEY SCAN CONTROL EVENT13[7:0] General EVENT8_STATE EVENT15[7:0] EVENT16[7:0] 09841-006 EVENT14[7:0] Figure 8. FIFO Operation As stated above, some of the onboard functions of ADP5585 can be programmed to generate events on the FIFO. A FIFO update control block manages updates to the FIFO. If an I2C transaction is accessing any of the FIFO address locations, updates are paused until the I2C transaction has completed. EVENT1[7:0] EVENT8[7:0] 09841-007 EC = 0 Figure 7. Breakdown of Eventx[7:0] Bits When events are available on the FIFO, the user should first read back the event count, EC[4:0], to determine how many events must be read back. Events can be read from the top of the FIFO only. When an event is read back, all remaining events in the FIFO are shifted up one location, and the EC[4:0] count is decremented. The 10 input/output pins can be configured to decode a keypad matrix up to a maximum size of 25 switches (5 × 5 matrix). Smaller matrices can also be configured, freeing up the unused row and column pins for other I/O functions. The R0 through R4 I/O pins comprise the rows of the keypad matrix. The C0 through C4 I/O pins comprise the columns of the keypad matrix. Pins used as rows are pulled up via the internal 300 kΩ (or 100 kΩ) resistors. Pins used as columns are driven low via the internal NMOS current sink. Rev. C | Page 9 of 40 ADP5585 Data Sheet VDD low and sensing whether a row pin is low or not. All row/column pairs are scanned; therefore, if multiple keys are pressed, they are detected. KEY SCAN CONTROL C2 R0 1 2 3 4 5 6 7 8 9 R1 R2 If Switch 6 is released, the connection between R1 and C2 breaks, and R1 is pulled up high. The key scanner requires that the key be released for two scan cycles because the release of a key is not necessarily in sync with the key scanner, it may take up to two full wait/scan cycles for a key to register as released. When the key is registered as released, and no other keys are pressed, the key scanner returns to idle mode. 3 × 3 KEYPAD MATRIX For the remainder of this document, the press/release status of a key is represented as simply a logic signal in the figures. A logic high level represents the key status as pressed, and a logic low represents released. This eliminates the need to draw individual row/column signals when describing key events. Figure 9. Simplified Key Scan Block Figure 9 shows a simplified representation of the key scan block using three row and three column pins connected to a small 3 × 3, nine-switch keypad matrix. When the key scanner is idle, the row pins are pulled high and the column pins are driven low. The key scanner operates by checking the row pins to see if they are low. KEY PRESSED KEY x KEY RELEASED Figure 10. Logic Low: Released, Logic High: Pressed Figure 11 shows a detailed representation of the key scan block and its associated control and status signals. When all row and column pins are used, a matrix of 25 unique keys can be scanned. If Switch 6 in the matrix is pressed, R1 connects to C2. The key scan circuit senses that one of the row pins has been pulled low, and a key scan cycle begins. Key scanning involves driving all column pins high, then driving each column pin, one at a time, PIN_CONFIG_A[7:0] PIN_CONFIG_B[7:0] PIN_CONFIG_C[7:0] RESET_TRIG_TIME[2:0] RESET1_EVENT_A[7:0] RESET1_EVENT_B[7:0] RESET1_EVENT_C[7:0] RESET2_EVENT_A[7:0] RESET2_EVENT_B[7:0] KEY RELEASED RESET 1_INITIATE RESET 2_INITIATE KEY SCAN CONTROL EVENT_INT OVRFLOW_INT I2C BUSY?

The key scanner has a wait time between each scan cycle; therefore, the key must be pressed and held for at least this wait time to register as being pressed. If the key is continuously pressed, the key scanner continues to scan, wait, scan, wait, and so forth. Figure 11. Detailed Key Scan Block Rev. C | Page 10 of 40 Data Sheet ADP5585 If a smaller 2 × 2 matrix is configured, for example, by using the C2 and C3 column pins and the R1 and R2 row pins, only the four event identifiers (8, 9, 13, and 14) can possibly be observed on the FIFO, as shown in Figure 11. By default, ADP5585 records key presses and releases on the FIFO. Figure 12 illustrates what happens when a single key is pressed and released. Initially, the key scanner is idle. When Key 3 is pressed, the scanner begins scanning through all configured row/column pairs. After the scan wait time, the scanner again scans through all configured row/column pairs and detects that Key 3 has remained pressed, which sets the EVENT_INT interrupt. The event counter, EC[4:0], is incremented to 1, EVENT1_IDENTIFIER[6:0] of the FIFO is updated with its event identifier set to 3, and its EVENT1_STATE bit is set to 1, indicating a press. 1 EC[4:0] KEY 3 PRESS FIFO 1 3 0 0 0 0 0 0 0 FIFO READ FIFO 0 0 0 0 0 0 0 0 1 FIFO KEY 32 RELEASE 0 3 0 0 0 0 0 0 Figure 13. Asserting the EVENT_INT Interrupt Key Pad Extension As shown in Figure 11, the keypad can be extended if each row is connected directly to ground by a switch. If the switch placed between R0 and ground is pressed, the entire row is grounded. When the key scanner completes scanning, it normally detects Key 1 to Key 5 as being pressed; however, this unique condition is decoded by the ADP5585, and Key Event 31 is assigned to it. Up to eight more key event assignments are possible, allowing the keypad size to extend up to 30. However, if one of the extended keys is pressed, none of the keys on that row is detectable. Activation of a ground key causes all other keys sharing that row to be undetectable. 09841-011 2 Figure 12. Press and Release Event The key scanner continues the scan/wait cycles while the key remains pressed. If the scanner detects that the key has been released for two consecutive scan cycles, the event counter, EC[4:0], is incremented to 2, and EVENT2_IDENTIFIER[6:0] of the FIFO is updated with its event identifier set to 3. Its EVENT2_STATE bit is set to 0, indicating a release. The key scanner returns to idle mode because no other keys are pressed. The solution to ghosting is to select a keypad matrix layout that takes into account three key combinations that are most likely to be pressed together. Multiple keys pressed across one row or across one column do not cause ghosting. Staggering keys so that they do not share a column also avoids ghosting. The most common practice is to place keys that are likely to be pressed together in the same row or column. Some examples of keys that are likely to be pressed together are as follows: The navigation keys in combination with Select. The navigation keys in combination with the space bar. The reset combination keys, such as CTRL + ALT + DEL. COL0 The EVENT_INT interrupt can be triggered by both press and release key events. As shown in Figure 14, if Key 3 is pressed, EVENT_INT is asserted, EC[4:0] is updated, and the FIFO is updated. During the time that the key remains pressed, it is possible for the FIFO to be read, the event counter decremented to 0, and EVENT_INT cleared. When the key is finally released, EVENT_INT is asserted, the event counter is incremented, and the FIFO is updated with the release event information.

Ghosting is created when three or more keys are pressed simultaneously on multiple rows or columns (see Figure 14). Key combinations that form a right angle on the keypad matrix can cause ghosting.

It scans the GPI inputs and updates accordingly. It then returns to idle immediately, it does not scan/wait, like the key scanner. As such, the GPI scanner can detect narrow pulses once they get past the 50 μs input debounce filter.

GPI Scan and Detect Block The current input state of each GPI can be read back using the GPI_STATUS_x registers. Each GPI can be programmed to generate an interrupt via the GPI_INTERRUPT_EN_x registers. The interrupt status is stored in the GPI_INT_STAT_x registers. GPI interrupts can be programmed to trigger on the positive or negative edge by configuring the GPI_INT_LEVEL_x registers. If any of the GPI interrupts is triggered, the master GPI_INT interrupt is also triggered. Figure 16 shows a single GPI and how it affects its corresponding status and interrupt status bits. GPO OUTPUT Each of the 10 input/output lines can be configured as a generalpurpose output (GPO) line. Figure 6 shows a detailed diagram of the I/O structure. See the Detailed Register Descriptions section for GPO configuration and usage. LOGIC BLOCKS Several of the ADP5585 input/output lines can be used as inputs and outputs for implementing some common logic functions. The R1, R2, and R3 input/output pins can be used as inputs, and the R0 input/output pin can be used as an output for the logic block. The outputs from the logic blocks can be configured to generate interrupts. They can also be configured to generate events on the FIFO.

C | Page 12 of 40 Data Sheet ADP5585 PWM BLOCK LOGIC BLOCK The ADP5585 features a PWM generator whose output can be configured to drive out on the R3 I/O pin. PWM on/off times are programmed via four 8-bit registers (see Figure 20). Each bit of the on or off time represents 1 µs. The highest frequency obtainable from the PWM is performed by setting the least significant bit of both the on and off time bit patterns, resulting in a 500 kHz signal with a 50% duty cycle. (R1) LA (R2) LB (R3) LC LA_INV LB_INV LY (R0) LC_INV LY_INV LOGIC_SEL[2:0] SET Q D CLR The PWM block provides support for continuous PWM mode as well as a one-shot mode (see Table 59). Additionally, an external signal can be AND’ed with the internal PWM signal. This option can be selected by writing a 1 to PWM_IN_AND (PWM_CFG[2]). The input to the external AND is the C3 I/O pin. C3 should be set to GPI. Note that the debounce for C3 results in a delay of the AND’ing, and can be turned on or off using Register 0x21.

Up to three reset trigger events can be programmed for RESET1. Up to two reset trigger events can be programmed for RESET2. The event scan control blocks monitor whether these events are present for the duration of RESET_TRIG_TIME[2:0] (Register 0x2E, Bits[4:2]). If they are, reset-initiate signals are sent to the reset generator blocks. The generated reset signal pulse width is programmable.

The user can press one of the reset event combinations and initiate a system wide reset. This alleviates the need for removing the battery from the system and doing a hard reset. It is not recommended to use the immediate trigger time (see Table 54) because this setting may cause false triggering. Interrupts The INT pin can be asserted low if any of the internal interrupt sources is active. The user can select which internal interrupts interact with the external interrupt pin in Register 0x3C (refer to Table 68). Register 0x3B allows the user to choose whether the external interrupt pin remains asserted, or deasserts for 50 µs, then reasserts, in the case that there are multiple internal interrupts asserted and one is cleared (refer to Table 67).

The interface can support clock frequencies of up to 1 MHz. If the user is accessing the FIFO or key event counter (KEC), FIFO/KEC updates are paused. If the clock frequency is very low, events may not be recorded in a timely manner. FIFO or KEC updates can happen up to 23 μs after an interrupt is asserted because of the number of I2C cycles required to perform an I2C read or write. This delay should not present an issue to the user. line low. The address of the register to which data is to be written is sent next. The ADP5585 acknowledges the register pointer byte by pulling the data line low. The data byte to be written is sent next. The ADP5585 acknowledges the data byte by pulling the data line low. The pointer address is then incremented to write the next data byte, until it finishes writing the n data byte. The ADP5585 pulls the data line low after every byte, and a stop condition completes the sequence. Figure 25 shows a typical byte read sequence for reading internal registers. The cycle begins with a start condition followed by the 7-bit device address (0x34 for all models except the ADP5585ACPZ-03-R7, 0x30 for the ADP5585ACPZ-03-R7 only), followed by the R/W bit set to 0 for a write cycle.
