ADP5586ACBZ-03-R7 - 10-I/O Keypad Decoder | Analog Devices
Teilenummer: ADP5586ACBZ-03-R7 ✓ AktivADP5586ACBZ-03-R7 Übersicht
An I/O expander is an interface IC that increases the number of digital input and output pins available to a microprocessor or microcontroller. Its place in the hierarchy is interface controller → I/O expander → keypad decoder → integrated circuit. By combining general-purpose I/O with automatic keypad scanning and event buffering, the ADP5586 reduces the polling burden on the host processor and can lower processor activity during keypad use.
The verified product information identifies 10 configurable I/O resources, programmable logic, pulse-generation functions, an integrated reset generator, and a FIFO capable of storing up to 16 events. The -03 configuration uses the I2C-compatible interface and provides a default configuration identified by distributor listings. This combination makes the device useful where a compact keypad, discrete controls, or mixed digital I/O must be connected through a small number of serial interface pins.
The ADP5586 architecture separates keypad decoding from the host processor. Keypad events can be captured in the 16-event FIFO and read over the serial interface, rather than requiring the processor to identify every press continuously. The programmable logic and pulse generators can support additional control functions, although individual timing limits, logic configurations, and I/O electrical characteristics must be confirmed in the manufacturer datasheet before final design release.
Typical uses include portable-device keypads, camera controls, remote-control panels, healthcare user interfaces, industrial instrumentation, and compact control modules. In each case, the 16-WLCSP footprint conserves board area, while the integrated keypad decoder can reduce firmware complexity. Systems requiring more general-purpose I/O than the ADP5586 provides can use a dedicated I/O expander such as PCA9536DR alongside the keypad function.
Designers should verify I2C address configuration, pull-up requirements, supported input and output drive levels, and the behavior of the RST and configuration pins in the Analog Devices ADP5586 Data Sheet (Rev. 0). Because the package is only 1.59 mm by 1.59 mm, PCB assembly should use suitable fine-pitch assembly capability, controlled solder-paste deposition, and inspection appropriate for the exposed land pattern.
This product page combines verified manufacturer and distributor information, a 16-event FIFO feature, package details, purchasing data, and engineering-oriented usage guidance. It also identifies the important limitation that the verified cross-reference results do not establish five distinct pin-compatible replacements for the -03 configuration, avoiding unsupported drop-in claims.

Portable Device Keypad
The ADP5586ACBZ-03-R7 fits portable keypads because it combines a 10-I/O port expander with an integrated keypad matrix decoder in a 1.59 mm by 1.59 mm 16-WLCSP package. The host processor reads captured events from the 16-entry FIFO through the I2C-compatible interface instead of scanning every keypad intersection continuously. This can simplify firmware and reduce processor activity during intermittent user input. The -03 default configuration is appropriate when the RST pin must retain its documented -03 function rather than become the R5 keypad row used by the -01 version. Before schematic release, confirm the supply range, key-scan timing, and I2C pull-up arrangement in the ADP5586 Data Sheet (Rev. 0).

Remote Control Panel
A remote-control panel can use the ADP5586ACBZ-03-R7 to consolidate multiple buttons and indicator-control outputs behind an I2C-compatible link. Its built-in keypad decoder captures matrix activity, while the FIFO stores up to 16 events for later retrieval. The 10 I/O resources leave capacity for additional panel signals beyond the keypad matrix, and the compact 16-WLCSP helps limit remote-control PCB area. Pulse-generation and programmable-logic functions may also support periodic control behavior where their timing requirements are acceptable. Firmware must handle event sequencing, device addressing, and recovery after an I2C interruption. Because the -03 and -01 options assign the RST pin differently, the PCB should follow the exact -03 pin and configuration plan.
Empfohlen
Camera Control Interface
The ADP5586ACBZ-03-R7 is suitable for compact cameras and imaging accessories that require several local controls without dedicating many host-controller pins. The integrated keypad matrix decoder manages user-button inputs, while the 16-event FIFO allows the host to read queued events over the I2C-compatible interface. Its 16-WLCSP footprint is valuable when PCB area is constrained, and the remaining I/O resources can support related panel signals. The device can also provide programmable logic and pulse outputs for compatible control tasks. Design verification should include the electrical levels of each I/O, debounce behavior, reset sequencing, and the maximum bus rate supported in the manufacturer documentation. Fine-pitch assembly and inspection are required because the package measures only 1.59 mm by 1.59 mm.
Empfohlen
Healthcare User Interface
The ADP5586ACBZ-03-R7 can support compact healthcare-device user interfaces that combine a keypad with a limited number of panel indicators or controls. A keypad matrix decoder offloads button scanning, and the 16-event FIFO provides a defined buffer between physical input and host processing. The I2C-compatible connection keeps the host wiring simple, while the small WLCSP package supports space-constrained handheld or bedside equipment. Medical-system designs must separately address applicable product safety, usability, and regulatory requirements; no medical certification is claimed for this component. Engineers should verify input thresholds, reset behavior, debounce configuration, and fault recovery using the Analog Devices ADP5586 Data Sheet (Rev. 0). The -03 option should be used only where its RST-pin behavior matches the intended reset architecture.
Empfohlen
Industrial Instrumentation Panel
ADP5586ACBZ-03-R7 suits industrial instrumentation panels that need a local keypad plus general-purpose digital controls behind a compact serial interface. The built-in keypad decoder and 16-event FIFO reduce repetitive host polling, while 10 I/O resources allow the same device to serve control and status functions. Its I2C-compatible architecture connects cleanly to embedded controllers, and the 16-WLCSP preserves board area in densely populated instrument chassis. Industrial qualification and extended-temperature suitability must be verified rather than assumed because those specifications were not present in the supplied data. Robust design also requires checking pull-ups, bus fault tolerance, grounding, and any applicable ESD requirements. Firmware should include timeout and reset recovery because a stuck host can affect both keypad operation and shared I/O behavior.
Empfohlen
Programmable Control and Indicator Panel
The ADP5586ACBZ-03-R7 can consolidate programmable logic, pulse generation, keypad decoding, and general-purpose I/O in a compact control panel. The -03 device is identified by distributors as the default configuration with an alternative I2C arrangement, making it suitable for designs that do not require the -01 option's R5 keypad-row assignment. Its 10 I/O resources can accommodate panel signals beyond the matrix keypad, while the 16-event FIFO helps decouple physical events from host servicing. Engineers should define which I/O channels are inputs, outputs, or logic functions before PCB routing. Exact output-drive limits, timing, and allowed logic combinations must come from the manufacturer datasheet. Verify that all connected loads and pull networks remain within the confirmed electrical limits.

- Highly integrated compact package (vs. PCA9536DR)
Designhinweise
Reserve the Analog Devices ADP5586 recommended land pattern and verify the 16-WLCSP assembly process against the manufacturer package drawing. The verified body size is only 1.59 mm by 1.59 mm, so stencil aperture design, solder-paste volume, component placement tolerances, and post-reflow inspection should be validated using the official package data. Avoid routing noisy switching-node copper beneath the device or its I2C traces.
Do not assume the ADP5586ACBZ-01-R7 and ADP5586ACBZ-03-R7 are software- or reset-equivalent. The manufacturer datasheet states that the -01 configuration uses the RST pin as keypad row R5. Confirm the selected ordering option, address configuration, RST behavior, and matrix assignment before layout release. Changing only the hardware revision in firmware can produce an unresponsive keypad or an unexpected I/O level.
Place the device and its required support components close to the I2C bus and keypad connector. Keep the SDA and SCL traces short, avoid stubs, and provide the pull-up arrangement required by the verified bus voltage and capacitance. Route keypad traces away from high-current switching paths and noisy analog inputs. If the FIFO is used to absorb intermittent events, ensure the host firmware services the bus within the device's documented timeout requirements.
Compliance-Informationen
The supplied verified data identifies the part as an active Analog Devices product but does not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status.
