ADP5585ACPZ-00-R7 - 10-I/O Keypad Controller | Analog Devices

The Analog Devices ADP5585ACPZ-00-R7 is a 10-I/O port expander with built-in keypad matrix decoder, programmable logic, reset generator, and PWM generator, supplied in a 16-LFCSP 3x3 mm package. The device is designed for portable and embedded systems that need additional input/output pins, key-event handling, or auxiliary control functions without increasing the host processor pin count. An I/O expander is an interface IC that increases the number of general-purpose inputs and outputs available to a host processor. The ADP5585 family combines this port-expansion function with a keypad matrix decoder and programmable logic, allowing a processor to scan keypad inputs and receive buffered events while using fewer host pins. This makes the device suitable for product interfaces, handheld equipment, industrial instrumentation, and other control systems with compact human-machine interfaces. The verified product information identifies 10 configurable I/Os, a 16-element FIFO for event recording, a built-in keypad decoder, programmable logic, a reset generator, and a PWM generator. The ADP5585ACPZ-00-R7 is specifically identified as the standard address configuration. The manufacturer datasheet also states that the 7-bit device address is 0x34 for all models except ADP5585ACPZ-03-R7, which uses 0x30. The 16-LFCSP 3x3 mm package supports compact PCB layouts in space-constrained portable products and instrument panels. Because the supplied web results do not publish the complete pin names or detailed electrical limits in machine-readable form, the package pinout and several electrical parameters are marked as requiring verification from the manufacturer datasheet before schematic capture or layout release. Typical applications include keypad entry, camera controls, remote controls, portable devices, healthcare equipment, industrial instrumentation, and other embedded human-interface systems. The internal FIFO can record input events while the host processes other tasks, while programmable logic can provide local decision-making or control behavior. The PWM generator is useful for LED indicators, simple dimming, or other low-frequency auxiliary functions when its electrical limits are appropriate for the load. Designers should confirm the I/O voltage, absolute maximum ratings, address configuration, capacitor requirements, and exposed-pad connection directly from the manufacturer datasheet. The I/O pins should also be checked for pull-up, pull-down, keypad, logic-level, or push-pull requirements before they are assigned to a board layout. This page combines verified manufacturer and distributor information with practical application guidance and explicitly identifies values that require datasheet confirmation.

ADP5585ACPZ-01-R7 - 10-I/O Keypad Controller | Analog Devices
ADP5585ACPZ-01-R7

ADP5585ACPZ-01-R7 - 10-I/O Keypad Controller | Analog Devices

Analog Devices ADP5585ACPZ-01-R7 is a 10-I/O port expander with an integrated keypad matrix decoder, programmable logic, reset generator, and PWM generator in a 16-LFCSP (3 x 3 mm) package. The device provides an I2C address of 0x34, 10 configurable I/Os, and event-recording capability through a 16-element FIFO. It is designed to increase the I/O capacity of a host processor while reducing the number of GPIO pins required for keypad scanning and auxiliary control functions. An I/O expander is an interface IC that extends the number of digital input and output lines available to a processor through a serial bus. In the product hierarchy, the ADP5585 is an I/O expander, an interface IC, and a power-management-adjacent system-support semiconductor. Its integration of keypad scanning, programmable logic, reset generation, and PWM generation can replace several discrete peripheral functions while conserving host-controller pins. The principal features include 10 configurable I/Os, a keypad matrix decoder supporting programmable scan operations, a 16-element FIFO for event recording, programmable logic, and a dedicated PWM generator. These functions are useful in handheld products, remote controls, cameras, healthcare equipment, industrial instrumentation, and human-interface panels. The integrated architecture reduces component count and can simplify firmware by moving repetitive scanning and event handling into dedicated hardware. Communication occurs through I2C-compatible serial transactions. According to the manufacturer datasheet, a transaction begins with a start condition, followed by the 7-bit device address and read/write bit. For ADP5585ACPZ-01-R7, the device address is 0x34, distinguishing it from the ADP5585ACPZ-03-R7 version, which uses 0x30. The part acknowledges the address byte by pulling the data line low, allowing the host to confirm that the target device is present and responding. Typical uses include portable-device keypads, camera control interfaces, remote-control panels, medical monitoring equipment, and industrial instrumentation. In each case, the device can manage multiple digital lines and matrix-scanning tasks while the main processor handles higher-level application logic. In designs requiring multiple PWM outputs, the internal generator reduces the need for external PWM circuitry, although exact timing, current, and configuration limits must be taken from the manufacturer datasheet. The principal design consideration is firmware and bus planning. Because the -01 and -03 order codes use different 7-bit I2C addresses, multiple identical devices can coexist on one bus if address selection and pull-up requirements are managed correctly. Firmware should also account for FIFO overflow conditions, event ordering, and the difference between input, output, and keypad-scanner configurations. The 3 x 3 mm LFCSP package requires a qualified land pattern and careful inspection because its small dimensions make solder bridging and assembly defects a concern. This product page consolidates verified manufacturer descriptions, distributor availability, family-level alternatives, interface details, and practical design guidance. It distinguishes confirmed ADP5585 features from parameters that still require verification in the manufacturer datasheet, helping engineers assess fit before beginning a PCB layout or firmware implementation.

ADP5585ACPZ-03-R7 - 10-I/O Keypad Controller | Analog Devices
ADP5585ACPZ-03-R7

ADP5585ACPZ-03-R7 - 10-I/O Keypad Controller | Analog Devices

Analog Devices ADP5585ACPZ-03-R7 is a 10-I/O port expander with an integrated keypad matrix decoder, programmable logic, reset generator, and PWM generator, supplied in a 16-LFCSP package. The device operates from a 3.6 V supply according to distributor data and communicates with a host processor through an I2C interface. Its ten configurable I/Os allow digital input, digital output, keypad scanning, or mixed functions to be assigned through registers. The ACPZ-03-R7 option uses the I2C device address 0x30, while other ADP5585 models use 0x34. An I/O expander is an interface IC that increases the number of general-purpose input/output pins available to a microcontroller or system processor. It sits between the host and external controls, allowing a device with limited pin count to operate keypads, indicators, interlocks, and other digital peripherals. The ADP5585 expands this role by including a keypad matrix decoder and programmable logic, reducing the host burden associated with scanning switch matrices and recording button events. Key verified features include 10 configurable I/Os, a built-in keypad matrix decoder, programmable logic, a reset generator, and a PWM generator. A 16-element FIFO supports event recording, allowing qualifying input events to be retained and transferred over the serial interface. The device is intended for portable equipment such as phones, remote controls, and cameras, as well as non-portable healthcare, industrial, and instrumentation systems. The ADP5585 combines GPIO expansion with peripheral functions in one small package. Its I2C control path provides a practical way to add external interfaces without assigning a dedicated host GPIO to every keypad line or status indicator. Register-programmable behavior allows the same device family to support different board layouts, while the reset and PWM blocks reduce the need for separate discrete functions in compact control systems. The target suffix identifies the 16-LFCSP, 3 x 3 mm, tape-and-reel configuration. The ACPZ-03-R7 version is distinguished from other ADP5585 variants primarily by its device address and detailed configuration options. Because the I2C address differs from 0x34, firmware and bus planning should specifically account for the 0x30 address of this ordering code rather than assuming the address used by every other device in the family. Designers should confirm pin functions, exposed-pad requirements, address selection, and electrical limits directly against the manufacturer datasheet before layout release. I2C pull-up placement, bus capacitance, level compatibility, and the exposed thermal and electrical pad connection must be evaluated on the complete board rather than in isolation. This page consolidates the verified manufacturer function description, distributor ordering data, package information, I2C-address distinction, and family cross-references into one engineering-focused record. It also identifies which replacement details remain unverified, helping engineers distinguish confirmed pin-compatible family references from assumptions that would require schematic, firmware, and datasheet review.

ADP5586ACBZ-00-R7 - 10-I/O Keypad Decoder | Analog Devices
ADP5586ACBZ-00-R7

ADP5586ACBZ-00-R7 - 10-I/O Keypad Decoder | Analog Devices

The Analog Devices ADP5586ACBZ-00-R7 is a 10-input/output port expander with a built-in keypad matrix decoder, programmable logic, reset generator, and pulse generators in a 16-WLCSP package measuring 1.59 mm by 1.59 mm. The device supports I2C communication up to 1000 kHz and operates from a supply rated up to 3.6 V. Its default configuration supports keypad-entry and general-purpose I/O expansion without requiring a dedicated host GPIO pin for every external signal. An I/O expander is an interface IC that increases the number of inputs and outputs available to a microprocessor or microcontroller. The ADP5586 belongs to the interface IC hierarchy and combines an I2C-controlled GPIO expansion function with keypad scanning, event processing, and dedicated timing logic. This combination can reduce host pin count while supporting matrix keypads, discrete controls, indicators, and other low-speed peripheral signals. Key features include 10 configurable I/O resources, an integrated keypad matrix decoder, programmable logic, a reset generator, and pulse generators. The I2C interface operates up to 1000 kHz, making the device suitable for systems that need compact peripheral expansion and organized keypad event handling. The -00 configuration is identified as the default-config variant, while the separate -01 product model changes how the RST pin is used. Technically, the device separates host interface traffic from keypad-scanning and programmable I/O functions. Its reset behavior provides controlled initialization, while pulse-generation and programmable-logic functions can reduce repetitive host firmware. According to the manufacturer datasheet, the RST pin includes a debounce filter. The -01 model uses that pin as an additional R5 keypad row, whereas the selected -00 model retains the documented reset-related behavior. Typical applications include portable-device keypads, remote controls, camera controls, healthcare panels, industrial instrumentation, and compact human-interface systems. It is most useful when a design needs several discrete inputs plus a matrix keypad but has limited host-controller GPIO pins. Because the device targets compact, mixed-signal control panels rather than high-speed peripheral buses, board-level I2C routing and exposed-pad assembly are important practical considerations. Designers should review the WLCSP land pattern, exposed-pad requirements, I2C pull-up placement, and the difference between the -00 and -01 RST configurations before release. A clean bypass-capacitor layout and short I2C traces help preserve signal integrity in dense portable or industrial equipment. This page combines verified manufacturer and distributor information with application guidance, selection criteria, and explicit uncertainty notes where detailed operating values or drop-in replacements were not provided.

It supports I2C communication up to 1000 kHz and is identified as a 3.6 V device. An I/O expander is a specialized interface IC that increases the number of inputs and outputs available to a host processor. It belongs to the hierarchy of interface IC, peripheral interface controller, and system semiconductor. The ADP5586 combines general-purpose port expansion with a dedicated keypad matrix decoder, making it useful where a system needs both configurable digital lines and matrix keypad scanning without allocating many host GPIO pins. The device provides 10 configurable I/O resources and supports a 6-row by 5-column keypad matrix. Additional onboard functions include programmable logic, reset generation, and pulse generation. The ADP5586ACBZ-01-R7-specific configuration assigns the active-low RST pin as an additional keypad row, R5, while the SW_RESET register bit or an undervoltage condition provides another reset path. The I2C interface operates at up to 1000 kHz, allowing efficient host communication for register configuration and real-time input monitoring. Its compact 16-WLCSP format reduces PCB area compared with a larger discrete keypad-scanning implementation, but its fine pitch requires careful PCB layout, inspection, and assembly planning. Analog Devices identifies the ADP5586 family as production product. Typical uses include portable-device keypads, remote controls, cameras, healthcare equipment, industrial control panels, and instrumentation. In each case, the device can scan a matrix keypad while exposing additional programmable lines for LEDs, control inputs, or other digital functions. Integrating these tasks in one package can reduce host GPIO usage and simplify the system interconnect. Designers should verify the exact pin functions, voltage limits, logic thresholds, and configuration registers against the manufacturer datasheet before layout. A low-noise supply and appropriately placed decoupling capacitors remain important because the device combines digital I/O, keypad scanning, and host-interface functions in one compact package. This product synthesis consolidates verified manufacturer and distributor information, a 16-WLCSP package description, current pricing references, pin-specific reset behavior, and application guidance. It also clearly distinguishes the target ordering code from broader ADP5586 family information and identifies where additional engineering verification is still required.

ADP5586ACBZ-03-R7 - 10-I/O Keypad Decoder | Analog Devices
ADP5586ACBZ-03-R7

ADP5586ACBZ-03-R7 - 10-I/O Keypad Decoder | Analog Devices

Analog Devices ADP5586ACBZ-03-R7 is a 10-input/output port expander with a built-in keypad matrix decoder, programmable logic, reset generator, pulse generators, and a 16-event FIFO in a 16-WLCSP package measuring 1.59 mm by 1.59 mm. The device communicates with a host processor through an I2C-compatible interface, allowing keypad and general-purpose I/O functions to be added without using a dedicated host I/O pin for every connection. 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.

It consolidates keypad scanning and additional digital I/O where a host processor has limited direct GPIO capacity. An I/O expander is an interface IC that extends a processor's input/output capacity over a serial bus. In the product hierarchy, the ADP5587 is an I/O expander, then a serial interface device and an integrated circuit. The ADP5587 adds value beyond ordinary GPIO expansion because its eight configurable GPIOs can operate as keypad rows or columns, while the remaining lines support general-purpose inputs, outputs, and interrupt signaling. Key features include support for an 18-GPIO configuration or a 10-by-8 keypad matrix, I2C auto-increment, an open-drain interrupt output, programmable pull-ups, key-press and key-release interrupts, a key-event counter with overflow indication, keypad locking, and a 275 microsecond debounce interval. These functions reduce host-side scanning logic while preserving event-driven communication with the processor. The device is designed around low-voltage mobile systems. Its I2C host interface runs at 400 kHz, and its 1.65 V to 3.6 V operating range suits compatible mobile and embedded rails. The compact WLCSP construction supports space-constrained handheld layouts, although its fine-pitch footprint demands careful PCB assembly, clean supply bypassing, and pin-accurate layout according to the Analog Devices package drawing. Typical uses include QWERTY keypad controllers, mobile handsets, portable navigation equipment, compact industrial user-interface panels, and other embedded products that need a dense matrix of switch inputs or additional GPIO lines. The host processor reads key events and configuration registers through I2C, while the interrupt line provides an event-driven indication of relevant key activity. For layout, keep I2C routing short, provide the required decoupling close to the supply pins, and verify the exposed-pad connection and assembly requirements in the manufacturer datasheet. Pull-ups must match the host voltage, bus capacitance, and timing budget. Software should also account for debounce, interrupt level programming, and event-counter overflow behavior. This page consolidates verified manufacturer and distributor facts, strict package constraints, application guidance, and clearly flagged data gaps. It distinguishes documented drop-in candidates from broader functional equivalents so engineers do not mistake a different footprint or feature set for a true PCB-level replacement.

Its position in the hierarchy is GPIO expander → keypad controller → interface IC → semiconductor. The ADP5587 family is intended for QWERTY-type phone designs and similar human-interface systems. Its GPIO expansion capability allows the host to scan controls, read switch states, drive indicator or control lines, and manage keypad rows and columns through the serial interface. The I2C interface with auto-increment supports efficient register access, while the compact 24-LFCSP-WQ package supports space-constrained mobile equipment. The verified data does not provide complete electrical limits, pin-level functions, or timing values, so those parameters remain marked for data completion rather than inferred. Typical applications include mobile phone keypads, portable navigation devices, handheld terminals, compact consumer equipment, and other products that need more host-controlled I/O than the processor exposes directly. The ADP5587 is particularly useful when a design needs both general-purpose digital lines and keypad scanning in one device. Compared with a pure GPIO expander, it adds keypad-oriented functions; compared with a larger host MCU, it can reduce processor pin count and centralize human-interface I/O. Designers should verify the package-specific pinout, I2C address configuration, voltage limits, and electrical timing against the manufacturer datasheet before layout. The compact WQ package also requires careful PCB escape routing and thermal assessment according to the manufacturer’s recommended land pattern. This page combines verified distributor availability and product descriptions with structured application guidance and clearly identifies parameters that require datasheet confirmation.

These functions consolidate several discrete peripheral functions into a compact 4 mm × 4 mm LFCSP-WQ package. Typical uses include QWERTY-style mobile phones, compact handheld devices, portable industrial controls, and embedded systems with a matrix keypad and limited host-GPIO availability. The 10 × 8 matrix can scan up to 80 switch positions, while the interrupt mechanism allows the host processor to remain inactive until a key or configured GPIO event occurs. Designers should verify the exact pin assignments, address configuration, pull-up settings, and interrupt polarity against the manufacturer datasheet before layout release. I2C pull-up placement and routing require attention because excessive capacitance or unsuitable resistor values can limit bus rise time. The compact package also demands careful thermal, assembly, and exposed-pad handling in accordance with the manufacturer’s land pattern. This page consolidates verified manufacturer and distributor information, exact source links, application guidance, and drop-in-family alternatives to support faster component selection while clearly identifying parameters for which additional design verification is required.

The device is designed for keypad and alarm-system interfaces where a compact controller can scan matrix keys, monitor external signals, and report events to a host processor. An I/O expander is an interface IC that increases the number of inputs and outputs available to a host without requiring a processor with a large integrated GPIO package. In the hierarchy of electronic components, the ADP5588 belongs to the interface-IC class, specifically a mobile I/O expander and keypad controller. Its GPIO resources can be configured as general-purpose inputs, general-purpose outputs, keypad rows, or keypad columns, allowing one device to support multiple panel functions. Key features include support for an 18-GPIO port expander or a 10 × 8 keypad matrix, dual light-sensor inputs identified as C8 and C9, I2C register read autoincrement, keypad lock capability, and key-press and key-release interrupts. The open-drain interrupt output supports signaling to a connected controller, while programmable pull-ups and GPI level programmability provide flexibility for panel-level signal conditioning and interrupt behavior. The ADP5588 datasheet identifies the device as a mobile I/O expander and QWERTY keypad controller intended for keypad and alarm-system interfaces. Its 1.8 V to 3.0 V operating range suits low-voltage embedded systems. The I2C host interface reduces the number of dedicated processor pins, and the GPIO/keypad multiplexing helps consolidate keypad scanning, auxiliary input, and output functions into a compact controller. Typical applications include QWERTY keypad panels, alarm-system user interfaces, compact control panels, mobile equipment, and industrial HMI modules. In a keypad implementation, the device can scan matrix rows and columns while generating key-press and key-release events. The dual light-sensor inputs can also support panel functions where analog light sensing is required, although the verified excerpt does not provide their electrical characteristics. Designers should confirm the exact CPZ pin mapping, exposed-pad connection, I2C address configuration, pull-up values, and interrupt polarity in the manufacturer datasheet before layout. Keep I2C traces short, provide the required pull-ups, and account for the open-drain interrupt output. Since this is a digital interface IC, SOA is not applicable.

ADP5588XCPZ-X2-R7

ADP5588XCPZ-X2-R7 - 18-GPIO Keypad Expander | Analog Devices

The Analog Devices ADP5588XCPZ-X2-R7 is an 18-GPIO I/O port expander and keypad controller with dual light-sensor inputs, I2C connectivity, and programmable key-event interrupts, packaged in a compact 4 mm × 4 mm surface-mount configuration. It operates from 1.8 V to 3.0 V and supports an 18-GPIO arrangement or a 10 × 8 keypad matrix. The supplied manufacturer information also identifies open-drain interrupt output, key-press and key-release interrupts, programmable pull-ups, a key-event counter, and keypad locking as principal device features. An I/O port expander is an interface IC that increases the number of general-purpose input/output lines available to a host processor. The ADP5588 belongs to the GPIO expander and keypad-controller hierarchy within interface ICs. Designed for QWERTY-style mobile phones and other keypad-oriented systems, it offloads matrix scanning, key decoding, light sensing, and interrupt handling from a main application processor whose package-pin budget may be constrained. The device can operate as an 18-GPIO port expander or as a 10 × 8 keypad matrix, allowing the same silicon to support both general-purpose line expansion and dedicated key-scanning duties. Its two light-sensor inputs provide additional peripheral integration in devices that need ambient-light measurement. Programmable pull-ups reduce external resistor requirements, while programmable interrupt behavior helps the host distinguish key presses, key releases, and general GPIO activity. Communication with the host occurs through an I2C interface. The I2C register read autoincrement feature supports efficient sequential register access, which is particularly useful when firmware must scan a keypad, read multiple GPIO states, or update several configuration registers. The open-drain interrupt output supports a shared, wired interrupt arrangement, with pull-up handling required on the host side according to the device implementation. Typical uses include mobile-phone keypad modules, handheld electronic equipment, industrial control panels, access-control keypads, alarm-system interfaces, and compact embedded systems requiring more input/output lines than the host controller can expose directly. It is also applicable to light-controlled user interfaces that need key scanning and analog light sensing within one small package. Designers should allocate the I2C address, pull-up resistors, and interrupt pull-up in the host schematic, then verify that the chosen -X2 ordering option satisfies the product temperature and qualification requirements for the intended application. Although the web data identifies the 4 mm × 4 mm package and tape-and-reel packaging, a complete verified pin map, exact package designation, temperature range, pricing, and lifecycle classification were not included in the supplied records. This product record consolidates the verified manufacturer features, distributor sourcing, functional positioning, and design guidance for the ADP5588XCPZ-X2-R7. It also clearly separates documented capabilities from unavailable pricing, pinout, compliance, and drop-in replacement data so engineers can make sourcing and design decisions without treating unverified assumptions as manufacturer specifications.

ADP5589ACBZ-00-R7 - 19-IO Keypad Decoder | Analog Devices
ADP5589ACBZ-00-R7

ADP5589ACBZ-00-R7 - 19-IO Keypad Decoder | Analog Devices

The Analog Devices ADP5589ACBZ-00-R7 is a 19-channel general-purpose input/output port expander with an integrated keypad matrix decoder, programmable logic, reset logic, and PWM generator, supplied in a 25-ball WLCSP package. The device operates from a 1.65 V to 3.6 V supply and can decode a keypad matrix as large as 11 rows by 8 columns. An I/O expander increases the number of digital inputs and outputs available to a host processor without requiring a large microcontroller package. The ADP5589 adds hardware-assisted keypad scanning to that conventional GPIO-expansion role, reducing firmware overhead in keypress, key-release, and keypad-lock applications. Its I/O pins can alternatively be programmed as GPI, GPO, or interrupt-capable inputs. Key features include 19 configurable I/Os, a 16-element event FIFO, key press and release interrupts, selectable interrupt levels, programmable 100 kΩ or 300 kΩ pull-up resistors, and 300 kΩ pull-down resistors. General-purpose outputs support push-pull or open-drain operation. Two programmable logic blocks extend the device beyond passive GPIO expansion, while internal and external PWM functions add mixed-signal timing capability. The ADP5589 is designed for portable equipment such as phones, remote controls, and cameras, as well as healthcare, industrial, and instrumentation systems. The serial interface reduces the number of host pins required when a design contains a matrix keypad, indicator LEDs, or additional control signals. Because the CBZ package is only 25 balls in an area smaller than most leaded packages, careful PCB layout is required for soldering, fanout, and signal integrity. Designers should verify I/O voltage limits, configure pull resistors for their external circuit, and reserve the interface pins for I2C communication and address selection. A 16-entry FIFO helps absorb asynchronous key events, but the host firmware must still process overflow and interrupt status. Because no verified cross-brand pin-compatible substitute was identified for the 25-ball CBZ footprint, replacement decisions should be based on an actual land-pattern and pin-function comparison rather than a similar GPIO-expander feature list. This page combines verified Analog Devices product information with distributor availability references, package analysis, application guidance, and a strict same-footprint replacement assessment that is not available from the manufacturer datasheet alone.

ADP5589ACBZ-01-R7 - 19 GPIO Channels | ADI Keypad Decoder
ADP5589ACBZ-01-R7

ADP5589ACBZ-01-R7 - 19 GPIO Channels | ADI Keypad Decoder

Analog Devices ADP5589ACBZ-01-R7 is a 19-channel GPIO port expander with an integrated keypad matrix decoder, programmable logic, reset logic, and PWM generator in a 25-ball WLCSP package measuring 1.99 mm by 1.99 mm. 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.

ADP5589ACBZ-02-R7 - 19-Channel GPIO/Keypad Expander | Analog Devices
ADP5589ACBZ-02-R7

ADP5589ACBZ-02-R7 - 19-Channel GPIO/Keypad Expander | Analog Devices

The Analog Devices ADP5589ACBZ-02-R7 is a 19-channel GPIO (General Purpose Input/Output) port expander with an integrated keypad matrix decoder, dual programmable logic blocks, reset logic and a PWM generator, housed in a 25-ball WLCSP (1.99 mm x 1.99 mm) package and operated from a 1.65 V to 3.6 V supply. An I/O expander is a type of interface IC that extends the number of general-purpose pins a host microcontroller can drive or read. It sits between the host and the outside world on a two-wire I2C bus, translating a small serial command set into parallel digital control of keys, LEDs, relays, and discrete logic. In the ADP5589 this generic function is fused with a dedicated hardware keypad decoder, so a single serial bus line replaces an entire scanned key matrix and its driver firmware. Key features include 19 configurable I/Os usable as keypad decoding lines for a matrix up to 11 x 8, key press and key release interrupts, key pad lock/unlock, a 16-element FIFO for event recording, GPI with selectable interrupt level, selectable 100 kOhm or 300 kOhm pull-up resistors, 300 kOhm pull-down resistors, and GPO outputs configurable as push-pull or open drain. Two independent programmable logic blocks allow simple hardware-level conditional functions without firmware polling, and the PWM generator supports both internal PWM generation and external PWM triggering through an internal PWM AND function. Technically the device offloads repetitive, latency-sensitive work from the host MCU. Because the keypad scan and debounce logic runs in hardware, the host receives event interrupts through the 16-deep FIFO rather than continuously polling a matrix, which reduces code size, CPU wake-ups and battery drain in portable designs. The 1.65 V to 3.6 V supply range spans mobile and battery-powered rails as well as standard 3.3 V industrial and instrumentation nodes. Typical applications include QWERTY-size keypad decoding in remote controls and handsets, GPIO expansion in portable consumer electronics, keypad plus LED feedback panels in healthcare devices, and programmable logic or PWM-driven indicator control in compact industrial instrumentation. A key design consideration is that the ADP5589 is a fixed-function device with configuration registers set over I2C, so it complements rather than replaces a fully programmable MCU. Layout should keep the 25-ball WLCSP on a clean ground plane with short I2C traces and adequate ball-to-ball decoupling.

The device supports QWERTY-size keyboard matrices, key press and release interrupts, keypad lock and unlock functions, configurable GPIO inputs and outputs, and internal or external PWM generation. A GPIO port expander increases the number of general-purpose input/output lines available to a host processor. The ADP5589 combines conventional I/O expansion with dedicated keypad-scanning resources, making it useful in portable devices, remote controls, cameras, healthcare equipment, industrial instrumentation, and other embedded systems. Its integrated programmable logic blocks can support event handling and programmable digital functions without requiring additional discrete logic. Key features include 19 configurable I/Os, a keypad matrix decoder for matrices up to 11 by 8, key press and release interrupts, selectable GPIO interrupt levels, 100 kΩ or 300 kΩ pull-up resistors, 300 kΩ pull-down resistors, push-pull or open-drain outputs, and a 16-element FIFO for event recording. The device also provides dual programmable logic blocks and PWM generation capabilities. The ADP5589 is intended for systems where a keypad matrix, auxiliary controls, indicator outputs, and event-driven logic must be connected to a processor with limited I/O pins. Its FIFO can record keypad events while the host processor is occupied with another task, reducing the risk of losing transient events. The integrated keypad decoder simplifies matrix scanning and event reporting while retaining programmable GPIO behavior. A typical implementation places the ADP5589 between a host serial interface and a matrix keypad or bank of auxiliary controls. Firmware configures the relevant pins as keypad rows, keypad columns, interrupt inputs, push-pull outputs, or open-drain outputs. The device reports key events through its interrupt mechanism, while the host reads event information over the serial interface. The exact electrical ratings and pin functions should be confirmed against the Analog Devices manufacturer datasheet before layout or firmware release. When designing a board around the ADP5589ACPZ-00-R7, preserve the manufacturer's recommended decoupling and signal-routing guidance, account for the exposed package pad and its thermal requirements, and define the host interface and interrupt polarity early. This page combines the verified manufacturer and distributor descriptions with application guidance, comparison data, and practical design notes to help engineers evaluate the device before implementation.

ADP5589ACPZ-01-R7

ADP5589ACPZ-01-R7 - 19-Channel GPIO Key Controller | Analog Devices

The Analog Devices ADP5589ACPZ-01-R7 is a 19-channel GPIO port expander with an integrated keypad matrix decoder, programmable logic, reset logic, and PWM generator, packaged in a 24-pin LFCSP-WQ (3.5 mm × 3.5 mm) surface-mount package. The device supports I2C-connected keypad and general-purpose I/O expansion, provides a 16-element FIFO for event recording, and is specified for operation up to 3.6 V according to distributor product data. An I/O expander is an interface IC that increases the number of general-purpose input/output pins available to a host processor. The ADP5589 belongs to the broader GPIO expander hierarchy and combines conventional port expansion with dedicated keypad-scanning functions. Its integrated keypad matrix decoder can handle QWERTY-size keyboards, while its programmable I/O channels can operate as inputs or outputs for control, status, and discrete interface signals. Key features include 19 configurable I/O channels, integrated keypad decoding, press and release interrupts, keypad lock and unlock functions, programmable logic, reset generation, and a PWM generator. The 16-element FIFO records GPIO or keypad events so the host processor can retrieve them through the serial interface. The -01 ordering code identifies a specific configuration within the ADP5589 family, while the -00 and -02 ordering codes represent other family variants whose detailed configuration differences require datasheet-level verification. The ADP5589 uses an I2C interface to connect a relatively low-pin-count microcontroller or application processor to additional keypad rows, columns, LEDs, control signals, or status inputs. Programmable logic can offload simple decision functions from the host processor, while the FIFO helps separate event production from event processing. This combination is especially useful when the host lacks sufficient direct GPIO pins or when a matrix keypad must share the same bus with other low-speed peripherals. Typical uses include QWERTY-size keypad interfaces in portable and medical equipment, camera and remote-control panels, industrial instrumentation, and compact human-machine interfaces. It is also applicable to GPIO-heavy control panels where key events, indicator outputs, and switch inputs must be managed over I2C. The small 3.5 mm × 3.5 mm package supports compact PCB layouts, although exposed-pad thermal management and careful high-speed trace routing remain important. Designers should verify the -01 variant’s register map and configuration limits against the current Analog Devices datasheet before treating another ordering code as a drop-in replacement. I2C pull-up placement, exposed-pad soldering, bus capacitance, and FIFO interrupt handling are the primary implementation considerations. The verified source data does not provide a complete pin list, operating-temperature range, current consumption, or exact logic thresholds.

ADP5589ACPZ-02-R7

ADP5589ACPZ-02-R7 - 19-Channel GPIO and Keypad Controller | Analog Devices

Analog Devices ADP5589ACPZ-02-R7 is a 19-channel GPIO port expander with a built-in keypad matrix decoder, programmable logic, reset logic, and PWM generator, supplied in a 24-LFCSP-WQ surface-mount package measuring 3.5 mm by 3.5 mm. It operates from a 1.65 V to 3.6 V supply and supports key matrices up to 11 × 8, while providing a 16-element FIFO for recording key events. A GPIO port expander is an interface IC that increases the number of general-purpose inputs and outputs available to a host processor. The ADP5589 combines that conventional expansion function with dedicated keypad decoding, programmable logic blocks, interrupt generation, and PWM generation. This integration reduces the need for separate matrix-scanning controllers and allows a host to monitor buttons, read switch states, drive LEDs, and generate pulse-width-modulated outputs through one device. The 19 configurable I/O channels support GPIO functions including key press and release interrupts, key lock and unlock functions, selectable interrupt levels, 100 kΩ or 300 kΩ pull-up options, and 300 kΩ pull-down resistors. General-purpose outputs can operate as push-pull or open-drain stages. Two programmable logic blocks add decision-making capability, and the integrated PWM generator supports internal PWM generation as well as external PWM configurations using internal logic signals. The ADP5589 is designed for systems where a primary microcontroller has too few pins for a keypad, indicator, or auxiliary control interface. Its FIFO can retain a sequence of key events for later processing, while interrupt signaling allows the host to react without continuously polling every input. The 24-LFCSP-WQ package supports compact portable equipment, instrumentation, healthcare, industrial, and remote-control designs. Typical uses include QWERTY and numeric keypads, portable medical controls, camera and remote-control interfaces, programmable industrial panels, and small embedded systems that need additional LEDs, switches, or logic-driven outputs. The device can reduce connector and host-pin requirements while centralizing scanning and event capture. Designers should confirm the exact -02 ordering option, pin mapping, exposed-pad connection, and electrical limits in the Analog Devices manufacturer datasheet before layout. Input levels, pull-up configurations, interrupt polarity, and keypad matrix dimensions must be checked against the host voltage and mechanical switch arrangement to avoid contention or unintended current draw. This product page consolidates manufacturer and distributor information, distinguishes documented ADP5589 order variants, and provides application guidance, comparison criteria, and sourcing context that are not presented as a single unified engineering summary in the underlying datasheet and distributor listings.

ADS1100A3IDBVRG4 - 16-Bit Self-Calibrating I2C ADC | Texas Instruments
ADS1100A3IDBVRG4

ADS1100A3IDBVRG4 - 16-Bit Self-Calibrating I2C ADC | Texas Instruments

The Texas Instruments ADS1100A3IDBVRG4 is a 16-bit, self-calibrating, delta-sigma analog-to-digital converter (ADC) with a single differential input, integrated programmable gain amplifier (PGA), internal oscillator, and I2C-compatible serial interface, packaged in a 6-pin SOT-23. The 'A3' device-slave-address suffix sets the I2C address to 0x48 (GND) or 0x4A (VDD) depending on the ADDR pin, and the part supports user-programmable data rates of 8, 16, 32, or 128 samples per second (SPS). It operates from a single 2.7 V to 5.5 V supply and performs conversions ratiometrically using the supply as the reference voltage. A delta-sigma (sigma-delta) ADC is a type of oversampling converter that uses a modulator loop and a digital decimation filter to achieve high resolution at low bandwidth. Within the broader converter taxonomy it belongs to the precision-ADC family, sitting between successive-approximation register (SAR) ADCs (faster, lower-resolution) and integrating ADCs (slowest, highest noise-rejection). The ADS1100 integrates the modulator, digital filter, PGA, and I2C interface into a single chip, making it a complete data-acquisition system in a tiny SOT-23-6 footprint suitable for board-constrained designs. Key features include a maximum integral nonlinearity (INL) of 0.0125% of full-scale range, no missing codes at 16 bits, continuous self-calibration, single-cycle conversion, PGA gains of 1, 2, 4, or 8, and low noise of 4 uVp-p. The continuous self-calibration scheme removes offset and gain drift in real time, eliminating the periodic user calibration required by many competing converters and simplifying long-running sensor measurements. Typical applications include portable instrumentation, weigh scales, industrial process control, factory-automation analog front-ends, battery monitors, and consumer sensor read-out boards where a small footprint, low power consumption, and I2C connectivity outweigh the need for higher sample rates or true differential bipolar inputs. The ratiometric conversion principle makes the ADS1100 especially attractive for bridge sensor measurements powered by the same rail as the ADC. A key design consideration is the supply used as the reference: any noise or drift on VDD appears directly in the conversion, so a clean, low-impedance supply with adequate decoupling is essential. The ADS1100A3IDBVRG4 is supplied on a 3000-piece tape-and-reel and is qualified for the -40 C to +85 C industrial temperature range. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, giving engineers a single source for selection, sourcing, and PCB implementation guidance.

ADS1100A5IDBVRG4

ADS1100A5IDBVRG4 - 16-Bit Self-Calibrating Sigma-Delta ADC | TI

The Texas Instruments ADS1100A5IDBVRG4 is a 16-bit, self-calibrating, single-channel delta-sigma analog-to-digital converter (ADC) with an integrated programmable gain amplifier (PGA) and I2C-compatible serial interface, housed in a 6-pin SOT-23 (DBV) package. Key headline parameters include 16-bit resolution with no missing codes, 128 samples per second (SPS) maximum data rate, and an input voltage range of 2.7V to 5.5V from a single supply. The device also offers an INL of 0.0125% of FSR maximum and 4 uVp-p low noise. An ADC (Analog-to-Digital Converter) is a semiconductor device that converts continuous analog voltage signals into discrete digital codes for processing by microcontrollers or DSPs. Delta-sigma (sigma-delta) ADCs use oversampling and noise shaping to achieve high resolution at low data rates, making them ideal for precision DC measurement applications such as industrial sensors, weigh scales, and temperature monitoring. Within the power management and signal chain hierarchy, the ADS1100 belongs to data acquisition ICs -> ADCs -> delta-sigma ADCs -> precision measurement converters. Key features include continuous self-calibration that corrects internal drift on every conversion, a single-cycle conversion mode for low-latency readings, and a programmable gain amplifier with gain of 8x that allows small sensor signals to be digitized directly without external amplification. The internal oscillator eliminates the need for an external clock, and the I2C interface simplifies connection to microcontrollers with only two wires. The architecture combines a delta-sigma modulator with a digital filter providing simultaneous 50Hz and 60Hz line rejection at the 8/16/32/128 SPS data rate selections. The self-calibration mechanism performs both offset and gain correction continuously, ensuring the 16-bit no-missing-codes performance is maintained across the operating range without user intervention. Conversions are performed ratiometrically using the power supply as the reference voltage, simplifying external circuit design. Typical applications include portable instrumentation, weigh scales, industrial process control, temperature and pressure sensor digitizers, battery management monitors, and consumer measurement products where PCB space is constrained. The SOT-23-6 footprint is among the smallest 16-bit ADC packages available, enabling single-board designs where board real estate is critical. When designing with this device, choose appropriate data rate vs. noise trade-off: 8 SPS gives best noise performance for thermocouple or weigh-scale signals, while 128 SPS enables faster response for general-purpose monitoring. Decouple VDD with 100nF close to the pin. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet.

ADS1100A6IDBVRG4 - 16-Bit I2C ADC with PGA, SOT-23-6 | TI
ADS1100A6IDBVRG4

ADS1100A6IDBVRG4 - 16-Bit I2C ADC with PGA, SOT-23-6 | TI

The Texas Instruments ADS1100A6IDBVRG4 is a self-calibrating, 16-bit, single-channel delta-sigma analog-to-digital converter (ADC) with a programmable gain amplifier (PGA), integrated oscillator, and I2C-compatible serial interface, housed in a 6-pin SOT-23 package. The A6 address variant targets designers who need address bit A0 tied high. It operates from a single 2.7 V to 5.5 V supply, performs conversions at 8, 16, 32, or 128 samples per second (SPS), and supports PGA gains of 1, 2, 4, and 8 for full-scale input ranges of ±2.048 V down to ±0.256 V when using the supply as reference. An ADC (analog-to-digital converter) is a data-acquisition component that converts continuous analog signals into discrete digital codes; delta-sigma ADCs in particular use oversampling and noise shaping to achieve high resolution at low sample rates. Within the broader hierarchy, this part is a precision sigma-delta ADC, which sits beneath successive-approximation (SAR) and pipeline ADCs in the data-converter taxonomy, and it ultimately belongs to the power-management-adjacent signal-chain IC family. The ADS1100's continuous self-calibration corrects internal drift on every conversion, yielding no missing codes at 16 bits and INL of 0.0125% of FSR maximum. Key features include single-cycle conversion, an effective 4 uVp-p low-noise floor at the higher PGA gains, on-chip PGA with gain 1/2/4/8, and ratiometric conversion that uses VDD as the reference for absolute measurements when an external reference is not desired. The I2C interface simplifies connection to virtually any microcontroller, and the I2C address is partially set by the A6 / A1 / A4 / A0 suffix scheme to allow multiple devices on one bus. Architecturally, the part combines a switched-capacitor delta-sigma modulator, a digital sinc³ filter, an offset and gain calibration DAC, and a PGA front end. The single-cycle settling of the digital filter ensures clean step responses for multiplexed inputs and removes the long filter-tail artifacts typical of higher-order sinc filters used at higher data rates. Typical applications include portable instrumentation, weigh scales, industrial process controls, factory-automation sensor transmitters, consumer battery-powered sensors, and temperature monitoring with thermocouples or RTDs using the PGA for small-signal gain. It is well suited wherever PCB area is constrained but 16-bit resolution is required. When designing, place 0.1 uF decoupling capacitors close to VDD and keep the analog inputs away from digital return currents; using VDD as the reference simplifies layout but means regulator noise directly couples to the conversion result.

ADS1100A7IDBVRG4

ADS1100A7IDBVRG4 - 16-Bit Self-Calibrating Delta-Sigma ADC | Texas Instruments

The Texas Instruments ADS1100A7IDBVRG4 is a 16-bit, self-calibrating, delta-sigma analog-to-digital converter with differential inputs, up to 16 bits of resolution, and a programmable gain amplifier offering gains of 1, 2, 4, or 8, packaged in a 6-pin SOT-23 (DBV). It operates from a single 2.7V to 5.5V supply, performs ratiometric conversions using the supply as the reference, and communicates via an I2C-compatible serial interface. An ADC (analog-to-digital converter) is an integrated circuit that converts continuous analog signals into discrete digital codes for processing by microcontrollers or DSPs. The delta-sigma (sigma-delta) architecture oversamples the input and uses noise-shaping to achieve high resolution and excellent noise rejection in low-frequency measurement applications such as sensor signal conditioning, industrial instrumentation, and portable measurement equipment. Key features of the ADS1100A7IDBVRG4 include no missing codes at 16-bit resolution, INL of 0.0125% of FSR maximum, continuous self-calibration that eliminates offset and gain drift over time and temperature, single-cycle conversion settling, low noise of 4 microvolts peak-to-peak, and a low quiescent current of 90 microamps typical. The programmable data rate of 8, 16, 32, or 128 samples per second allows the user to trade resolution for speed. The device integrates an oscillator, PGA, and I2C interface on-chip, eliminating the need for external components beyond bypass capacitors. The differential input topology rejects common-mode noise, making it well-suited for bridge sensors, thermocouples, and battery-cell monitoring. The internal clock and self-calibration simplify firmware and reduce long-term drift. Typical applications include portable instrumentation, weigh scales, industrial process control, consumer temperature monitoring, and battery-powered sensor nodes. The SOT-23-6 footprint enables integration into space-constrained designs, while the I2C interface supports multi-device bus configurations for scalable measurement systems. When designing with this part, note that the SOT-23-6 package requires careful PCB thermal management at higher data rates, and the I2C address is factory-programmed by part number suffix. Designers should consult the TI ADS1100 datasheet for the address selection options and self-calibration timing considerations.

ADS1110A3IDBVR - 16-Bit 240SPS Delta-Sigma ADC | Texas Instruments

The Texas Instruments ADS1110A3IDBVR is a precision, continuously self-calibrating 16-bit delta-sigma analog-to-digital converter with differential inputs, an internal 2.048V reference, an onboard PGA, and an I2C-compatible serial interface, all housed in a 6-pin SOT-23 package. It supports conversion rates of 15, 30, 60, and 240 samples per second, operates from a single 2.7V to 5.5V supply, and provides an input range of ±2.048V differentially when used with its internal reference. The SOT-23-6 footprint makes it one of the smallest self-contained 16-bit ADCs on the market. A delta-sigma ADC is a converter architecture that uses oversampling and digital filtering to achieve high resolution and excellent noise rejection, especially at low bandwidths. The ADS1110 belongs to the precision ADC category within data converters, sitting in the hierarchy: delta-sigma ADC -> ADC -> data converter -> signal chain IC -> semiconductor. The architecture's inherent noise-shaping makes it well suited for low-frequency, high-accuracy measurements such as temperature, strain-gauge, and battery monitoring, where successive-approximation (SAR) ADCs often trade off noise for speed. Key differentiating features include the integrated 2.048V reference with 5 ppm/°C typical drift, a programmable PGA with gains of 1, 2, 4, or 8, and a continuous self-calibration scheme that corrects internal offset and gain errors on every conversion. The device also integrates an internal oscillator, eliminating the need for an external clock, and offers four I2C slave addresses via the AD0 pin (only two of which are unique to the SOT-23-6 ADS1110A0/A1/A2/A3/A4/A5/A6/A7 family, depending on order code). From a technical perspective, the converter uses a third-order modulator followed by a digital sinc³ filter, providing simultaneous 50 Hz and 60 Hz mains rejection at the 15 SPS data rate. The internal PGA lets full-scale ranges be programmed from ±2.048V down to ±0.256V, allowing direct interfacing with low-amplitude sensors such as thermocouples, bridge outputs, and shunt currents without external instrumentation amplifiers. Typical applications include portable instrumentation, weigh scales, industrial process control, smart transmitters, consumer electronics, and factory automation. It is also frequently used in battery monitoring and fuel gauging thanks to its low supply current and differential input structure. When designing with the ADS1110, pay attention to the I2C pull-up resistor selection and the input common-mode range. The device's inputs are true differential, but the absolute voltage on each input must remain between GND and VDD, which constrains how the part can be interfaced to bipolar sensors.
