GENERAL DESCRIPTION

The ADP5589 is a 19 I/O port expander with built-in keypad matrix decoder, programmable logic, reset generator, and PWM generator. I/O 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 ADP5589, which handles all key scanning and decoding, can flag the main processor via an interrupt line when new key events have occurred. In addition, GPI changes and logic changes can be tracked as events via the FIFO, eliminating the

need to monitor different registers for event changes. The
ADP5589 is equipped with a FIFO to store up to 16 events.
Events can be read back by the processor via an I interface.
The ADP5589 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, saving board area and cost.

DEVICE OVERVIEW

The ADP5589 contains 19 multiconfigurable input/output pins. Each pin can be programmed to enable the device to carry out its various functions, as follows:
Keypad matrix decoding (11-column by 8-row matrix
maximum).
General-purpose I/O expansion (up to 19 inputs/outputs).
PWM generation.
Clock division of externally supplied source.
Dual logic function building blocks (up to three inputs,
one output).
Two re s et generators.
All 19 input/output pins have an I/O structure, as shown in Figure 6.
DD

I/O
DRIVE
300k
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 push-pull 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 I

C interface. Feedback of device status and pending interrupts can be flagged to an external processor via the
INT
pin.

DETAILED DESCRIPTION

EVENT FIFO

It is important to understand the function of the event FIFO. The ADP5589 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.
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 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 Tab le 1 1 for event decoding.
OVRFLOW_INT
KEY EVENTS
GPI EVENTS
LOGIC EVENTS
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.

FIRST READ
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.
Some of the onboard functions of ADP5589 can be program­med to generate events on the FIFO. A FIFO update control block manages updates to the FIFO. If an I accessing any of the FIFO address locations, updates are paused until the I
A FIFO overflow event occurs when more than 16 events are generated prior to an external processor reading a FIFO and clearing it.
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.

KEY SCAN CONTROL

General

The 19 input/output pins can be configured to decode a keypad
09714-006
matrix up to a maximum size of 88 switches (11 × 8 matrix). Smaller matrices can also be configured, freeing up the unused row and column pins for other I/O functions.
The R0 through R7 I/O pins comprise the rows of the keypad matrix. The C0 through C10 I/O pins comprise the columns of the keypad matrix. Pins used as rows are pulled up via the internal 300 k (or 100 k) resistors. Pins used as columns are driven low via the internal NMOS current sink.

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.
If Switch 6 in the matrix is pressed, R1 connects to C2. The key scan circuit senses that one of the row pins is 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, 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.
To prevent glitches or narrow press times being registered as a valid key press, the key scanner requires the key be pressed for two scan cycles. 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.
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.
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.

Use Registers PIN_CONFIG_A[7:0] (0x49), PIN_CONFIG_B[7:0] (0x4A), and PIN_CONFIG_C[2:0] (0x4B) to configure I/Os for keypad decoding. The number label on each key switch represents the event identifier that is recorded if that switch is pressed. If all row/column pins are configured, it is possible to observe all 88 key identifiers on the FIFO.
If a smaller 3 × 3 matrix is configured, for example, using the C5, C6, and C7 column pins and the R1, R2, and R3 row pins, only the nine event identifiers (17, 18, 19, 28, 29, 30, 39, 40, and 41) can possibly be observed on the FIFO, as shown in Figure 11.
By default, the ADP5589 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 32 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 32 has remained pressed, which sets the EVENT_INT interrupt. The event counter, EC[4:0], is incre­mented to 1, EVENT1[7:0] of the FIFO is updated with its event identifier set to 32, and its Event1_State bit is set to 1, indicating a press.

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[7:0] of the FIFO is updated with its event identifier set to 32. Its Event2_State bit is set to 0, indicating a release. The key scanner goes back to idle mode because no other keys are pressed.
The EVENT_INT interrupt can be triggered by both press and release key events. As shown in Figure 13, if Key 32 is pressed, EVENT_INT is asserted, EC[4:0] is updated, and the FIFO is updated. During the time that the key is still 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 incremented, and the FIFO updated with the release event information.

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 whole row is grounded. When the key scanner completes scanning, it normally detects Key 1 to Key 11 as being pressed; however, this unique condi­tion is decoded by the ADP5589, and Key Event 89 is assigned to it. Up to eight more key event assignments are possible, allowing the keypad size to extend up to 96. 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.

Ghosting

Ghosting is an occurrence where, given certain key press com­binations on a keypad matrix, a false positive reading of an additional key is detected. 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.
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.

FIFO Lock/Unlock

The ADP5589 features a lock mode, whereby events are pre­vented from updating the FIFO or the event counter or from generating EVENT_INT interrupts until an unlock event is detected.
The lock feature is enabled by setting the LOCK_EN (0x37[0]) bit or, alternatively, by a user programmable key or GPI event (set via EXT_LOCK_EVENT[7:0], Address 0x35). If the lock feature is enabled by the LOCK_EN bit, the LOCK_STAT (0x02[5]) bit is set. If the lock feature is enabled by an external event, then the LOCK_STAT bit is set, and a LOCK_INT interrupt is generated.
Unlock events are programmed via the UNLOCK1[7:0] (0x33) and UNLOCK2[7:0] (0x34) registers. Bits[6:0] comprise the even number. Bit 7 determines the active/inactive event (see the UNLOCK1 Register 0x33 (Tabl e 59 ) and the UNLOCK2 Register 0x34 (Tabl e 60 ).
If the user chooses to use only one unlock event, only the UNLOCK1[7:0] register should be programmed. Unlock events can be key press events (Event 1 to Event 88). Key release events are ignored when the keypad is locked and should not be used as unlock events.
GPIs configured to generate FIFO updates can also be used as unlock events (Event 97 to Event 115, either active or inactive). If either UNLOCKx register is programmed with Value 127 (Event 127), this means that any allowable event (key or GPI) is the unlock event. For example, if UNLOCK1[6:0] is programmed with 17, and UNLOCK2[6:0] is programmed with 127, the unlock sequence is Key 17 press followed by any other allowable event.
If the first unlock event is detected, partial unlock has occurred. If the next event after the first unlock event is not the second unlock event, then a full lock state is entered again. If the next event after the first unlock event is the second unlock event, then LOCK_STAT is cleared, and a LOCK_INT interrupt is generated. The user can at any stage clear LOCK_EN. This clears the LOCK_STAT bit but does not cause a LOCK_INT interrupt to be generated.
Rev. A | Page 12 of 48
Page 13
ADP5589
When full unlock is achieved, FIFO and event count updates resume. Note that if a key press is used as the second unlock event, the release of that key is captured on the FIFO after unlocking is completed.
The ADP5589 features an unlock timer, UNLOCK_TIMER[2:0] (0x36[2:0]). When enabled, after the first unlock event occurs, the unlock timer begins counting, and the second unlock event must occur before the unlock timer expires. If the unlock timer expires, the first unlock event must occur again to restart the unlock process. Figure 15 shows a simple state diagram of the unlocking process.

When lock mode is enabled, no EVENT_INT interrupts can be generated until the unlock events occur.
The ADP5589 features an interrupt mask timer, INT_MASK_ TIMER[4:0] (0x36[7:3]). When this timer and lock mode are enabled, a single EVENT_INT is generated if any key is pressed or any GPI (programmed to update the FIFO) is active. When the EVENT_INT is generated, the mask timer begins counting. No additional EVENT_INT interrupts are generated until the mask timer expires and a new key is pressed or any GPI (programmed to update the FIFO) is active, unless the unlock events occur, in which case, normal operation is resumed.
Allowing a single EVENT_INT interrupt is useful to alert the processor to turn on its screen and display an unlock message to the user. Blanking out additional key presses ensures that the processor is not unnecessarily interrupted until the unlock events occur. Figure 16 shows the unlock sequence when the interrupt mask timer is enabled.

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 inputs being high or on inputs being low via the GPI_INT_LEVEL_x registers. If any of the GPI interrupts is triggered, the master GPI_INT interrupt is also triggered.
Figure 18 demonstrates a single GPI and how it affects its corresponding status and interrupt status bits.

Figure 19. Multiple GPI Lines Example
The GPI scanner is idle until it detects a level transition. 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 s input debounce filter.

GPIs (programmed for FIFO updating) can be used as keypad unlock events via the UNLOCKx registers (see the FIFO Lock/Unlock section). The LCK_TRK_GPI bit can be used to allow GPIs (programmed for FIFO updating) to be tracked when the keypad is locked.

GPO OUTPUT

Each of the 19 I/O lines can be configured as a general-purpose 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 ADP5589 I/O lines can be used as inputs and outputs for implementing some common logic functions.
The R1, R2, and R3 I/O pins can be used as inputs, and the R0 I/O pin can be used as an output for Logic Block 1.
The C8, C7, and C6 I/O pins can be used as inputs, and the C9 I/O pin can be used as an output, for Logic Block 2. It is also possible to cascade the output of Logic Block 1 as an alternate input for Logic Block 2 (LY1 is used instead of LA2).

PWM BLOCK

The ADP5589 features a PWM generator whose output can be configured to drive out on I/O Pin R3. PWM on/off times are programmed via four 8-bit registers.
Newly programmed values are not latched until the final byte, PWM_ONT_HIGH_BYTE (Address 0x41, Bits[7:0]), is written to (see Figure 23).
The highest frequency obtainable from the PWM is performed by setting the least significant bit (LSB) of both the on and off bit patterns, resulting in a 500 kHz signal with a 50% duty cycle. Each LSB respresents 1 µs of on or off time.
The PWM block provides support for continuous PWM mode as well as a one-shot mode (see Tab l e 7 4 ). 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 C6 I/O pin. C6 should be set to GPI (GPIO15). Note that the debounce for C6 will result in a delay of the AND’ing, and can be controlled using register GPI_15_DEB_DIS (Address 0x28, Bit[6]).
Newly programmed values are not latched until the final byte, PWM_ONT_HIGH_BYTE (Address 0x41, Bits[7:0]), is written.

CLOCK DIVIDER BLOCK

The ADP5589 features a clock divider block that divides down the frequency of an externally supplied source via I/O Pin C6. The output of the divider is driven out on I/O Pin R3.

RESET BLOCKS

The ADP5589 features two reset blocks that can generate reset conditions if certain events are detected at the same time. 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_TRIGGER_TIME[2:0] (0x3D[4:2]). If they are, reset-initiate signals are sent to the reset generator blocks. The generated reset signal pulse width is programmable.

The RESET1 signal uses I/O Pin R4 as its output. A pass­through mode allows the main
RST
pin to be output on the
R4 pin also.
The RESET2 signal uses I/O Pin C4 as its output.
The reset generation signals are useful in situations where the system processor has locked up and the system is unresponsive to input events. 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 performing a hard reset.
It is not recommended to use the immediate trigger time (see the details of the RESET_CFG Register, 0x3D, in Tab l e 69 ) because this setting may cause false triggering.

INTERRUPTS

The sources is active. The user can select which internal interrupts interact with the external interrupt pin in register INT_EN (Address 0x4E, Bits[7:0]) (refer to ). 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 ).

REGISTER INTERFACE

Register access of the ADP5589 is acquired via its I2C-compatible serial interface. 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 I to perform an I

an issue to the user.
Figure 27 shows a typical write sequence for programming an internal register. The cycle begins with a start condition, followed by the hard coded 7-bit device address, which for the ADP5589 is 0x34, followed by the R/

4 LOGIC1_INT R/W 0 = no interrupt.
1 = interrupt due to a general Logic 1 condition. Write a 1 to this bit to clear it.
3 LOCK_INT R/W 0 = no interrupt.
1 = interrupt due to a lock/unlock condition. The user can read LOCK_STAT (0x02[5]) to determine if LOCK_INT is due to a lock or unlock event. If LOCK_STAT = 1, LOCK_INT is due to a lock event. If LOCK_STAT = 0, LOCK_INT is due to an unlock event. Write a 1 to this bit to clear it. If lock mode is enabled via the software bit LOCK_EN (0x37[0]), a LOCK_INT is not generated because the processor knows it just enabled lock mode. If lock mode is disabled (while locked) via the software bit LOCK_EN, a LOCK_INT is not generated because the processor knows it just disabled lock mode.
2 OVRFLOW_INT R/W 0 = no interrupt.
1 = interrupt due to an overflow condition. Write a 1 to this bit to clear it.
1 GPI_INT R/W 0 = no interrupt.
1 = interrupt due to a general GPI condition. This bit is not set by a GPI that has been configured to update the FIFO and event count. Write a 1 to this bit to clear it. This bit cannot be cleared until all GPI_x_INT bits are cleared.
0 EVENT_INT R/W 0 = no interrupt.
1 = interrupt due to key event (press/release), GPI event (GPI programmed for FIFO updates), or Logic 1/Logic 2 event (programmed for FIFO updates).Write a 1 to this bit to clear it.

The seven lower bits of each FIFO location contain the event identifier, which can be decoded to reveal the event recorded.
Table 11 outlines each event number, what it represents, and the I/O pins associated with it. Bit 7 is the Event 1 state.
For key events (Event 1 to Event 96). 1 = key is pressed. 0 = key is released. For GPI and logic events (Event 97 to Event 117). 1 = GPI/logic is active. 0 = GPI/logic is inactive. Active and inactive states are programmable.
