ADP5589ACBZ-01-R7 - 19 GPIO Channels | ADI Keypad Decoder
N.º de pieza: ADP5589ACBZ-01-R7 ✓ ActivoADP5589ACBZ-01-R7 Descripción general
An I/O expander is an interface IC that increases the number of general-purpose inputs and outputs available to a host processor. In the product hierarchy, the ADP5589 belongs to the GPIO port expander and interface IC family, where it combines digital I/O expansion with dedicated keypad-scanning and event-management functions. This integration allows one serial interface to control a matrix keypad, additional digital lines, and programmable outputs while reducing the number of host GPIO pins required.
The device provides 19 configurable I/O channels and includes a 16-element FIFO for recording key events. Its keypad decoder can handle matrix-keypad scanning up to 8 columns by 8 rows, or 8 by 8 as stated in the manufacturer documentation, and supports key press and release interrupts. Programmable logic, reset generation, and a PWM generator extend its use beyond simple bidirectional GPIO expansion.
The ADP5589 is intended for portable equipment such as phones, remote controls, and cameras, as well as healthcare, industrial, and instrumentation systems. The same 25-ball WLCSP package helps limit board area in space-constrained products. A key advantage over a collection of discrete I/O and keypad-controller devices is the consolidation of scanning, event buffering, programmable functions, and general-purpose I/O into one interface IC.
Typical uses include matrix-keypad decoding, consumer remote controls, camera controls, medical-device panels, industrial instrumentation interfaces, and portable electronic products. The manufacturer identifies portable and non-portable applications as the principal markets for I/O expanders of this type.
Designers should verify the complete electrical limits, serial-interface timing, logic levels, programming model, and ball assignments in the Analog Devices ADP5589 datasheet before layout. Because the device is supplied in a 1.99 mm by 1.99 mm WLCSP, careful escape routing, clean ground return paths, and assembly-process planning are important implementation considerations.
This page combines the verified manufacturer feature set, distributor pricing, source links, design guidance, and application analysis to provide practical information beyond a basic distributor catalog entry. All available pricing information is stated as of 2026-10-29, and unverified electrical details are identified rather than estimated.

Aplicaciones típicas
ADP5589ACBZ-01-R7 es adecuado para 6 aplicacións: Matrix Keypad Decoding, Remote Control Interfaces, Camera and Portable Controls, Healthcare Equipment Panels, Industrial Instrumentation, Programmable Indicator and Control Outputs.
Matrix Keypad Decoding
The ADP5589ACBZ-01-R7 fits matrix-keypad designs because it combines keypad decoding with 19 configurable I/O channels in one 25-ball WLCSP. According to the Analog Devices ADP5589 documentation, the decoder supports matrices up to 8 columns by 8 rows and can report key press and release events. Its 16-element FIFO records events between host interactions, reducing the need for the processor to poll every matrix position continuously. This integration is particularly useful where keypad scanning, limited host pins, and compact board area must be handled together.
Remote Control Interfaces
A remote-control design can use the ADP5589ACBZ-01-R7 to decode a matrix keypad and retain additional programmable I/O for indicators or controls. Its 19 configurable channels and dedicated key press and release interrupts allow a low-power host processor to receive meaningful events rather than repeatedly scanning raw key lines. The 25-ball WLCSP occupies only a 1.99 mm by 1.99 mm area, helping manufacturers meet the compact mechanical constraints of handheld remote controls while consolidating keypad and peripheral-control functions.
Camera and Portable Controls
The ADP5589ACBZ-01-R7 is appropriate for cameras and similar portable products that need a compact keypad plus additional digital control lines. The manufacturer identifies cameras, phones, and remote controls as applications for the ADP5589 family. With 19 configurable I/O channels, an 8-column by 8-row keypad capability, and a 16-element event FIFO, one device can handle user inputs and selected control signals. The package footprint preserves PCB area, while programmable outputs can provide dedicated indicator or control functions.
Healthcare Equipment Panels
Healthcare and diagnostic panels often require several user inputs and status signals without allocating excessive processor GPIO pins. The ADP5589ACBZ-01-R7 supplies 19 configurable channels and a dedicated keypad matrix decoder, allowing a compact controller interface to support operator controls. Its FIFO and key press or release interrupts help organize event handling. Because Analog Devices lists healthcare among the non-portable applications for I/O expanders, the device is relevant to medical equipment where keypad scanning and auxiliary I/O must coexist.
Industrial Instrumentation
Industrial instrumentation can benefit when a front-panel keypad and discrete digital controls share a limited host interface. The ADP5589ACBZ-01-R7 provides 19 configurable I/O channels, key press and release interrupts, programmable logic, reset logic, and PWM generation within one package. The integrated 16-element FIFO can hold keypad events for staged processing, while programmable GPIO expands the available control and monitoring lines. Engineers should verify voltage levels, timing, reset behavior, and industrial temperature requirements against the official datasheet before deployment.
Programmable Indicator and Control Outputs
The ADP5589ACBZ-01-R7 can serve as both an I/O expander and programmable output controller when a system needs more than basic digital lines. Its integrated PWM generator supports applications requiring an adjustable output signal, while the programmable logic and 19 configurable channels provide flexible signal routing. Compared with adding separate GPIO, PWM, and reset devices, the integrated 25-ball WLCSP can reduce component count and conserve board area, although the designer must confirm the exact PWM and logic parameters in the manufacturer documentation.

Notas de diseño
Treat the 1.99 mm by 1.99 mm 25-ball WLCSP as a fine-pitch assembly constraint. Route the host interface, keypad lines, power, ground, and any required exposed-ball connections directly from the manufacturer reference layout and pin table. Confirm whether the selected board side or land pattern requires a specific WLCSP footprint and whether the thermal or ground ball must be connected according to the datasheet.
Keep the keypad and host-interface escape traces short and place required bypassing capacitors close to their associated device pins using the values and placement guidance specified in the Analog Devices datasheet. Maintain a continuous ground reference beneath and around the WLCSP where board density allows. Review the exact ball map before final routing because the verified search snippets do not provide a complete numbered 25-ball assignment.
Do not treat ADP5589ACBZ-00-R7 as an automatic substitute for ADP5589ACBZ-01-R7. The available cross-reference result identifies the -00 ordering code but does not confirm pin-to-pin compatibility, register behavior, or electrical equivalence. Before substitution, compare the official datasheets, configuration options, package drawings, supply limits, and reset behavior. Also do not derive an unverified ball-level pinout from a generic WLCSP library.
Verify the ADP5589's supply range, I/O voltage limits, power consumption, and power-sequencing requirements from the manufacturer datasheet before connecting it to a host bus. Use the recommended bypass network and exposed-ball connection exactly as specified. Because those electrical details were not included in the supplied verified snippets, they should not be inferred from the package name or from the $0.7401 distributor reference price.
Información de cumplimiento
The supplied verified web results do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These fields remain unknown rather than being inferred from the manufacturer or package type.
