ADP5588XCPZ-X2-R7

Overview

The ADP5588XCPZ-X2-R7 is an I/O expander and column keypad scanner manufactured by Analog Devices Inc. It operates within a supply voltage range of 1.7 V to 3 V and features 18 general-purpose I/O pins. The device supports I2C serial communication with a maximum clock frequency of 400 kHz. It includes interrupt output capabilities and is housed in an LFCSP-24 package suitable for surface mount installation. The component functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates column keypad scanning functionality with general-purpose I/O expansion capabilities
• Provides interrupt output support for efficient event handling
• Supports standard I2C serial interface protocols

Applications

• Embedded systems requiring keypad input and GPIO expansion
• Portable electronic devices with limited pin availability
• Industrial control interfaces utilizing I2C communication

Procurement Notes

Verify the exact suffix against official Analog Devices documentation, as non-standard suffixes may indicate specific tape-and-reel configurations or regional variants. Confirm RoHS compliance status through the manufacturer's current datasheet before procurement. Ensure the supplier provides traceable origin documents matching the specified part number to avoid counterfeit components.

Selection Notes

Select this component when a low-voltage I2C interface is required alongside integrated keypad scanning. Compare the 18 I/O count against system requirements to ensure sufficient expansion capacity. Verify that the LFCSP-24 package dimensions fit the target PCB layout constraints. Check if the 400 kHz I2C speed meets the system's data throughput needs.

Part Context

This part belongs to the ADP5588 series of I/O expanders designed for embedded applications. It complements other Analog Devices interface solutions by providing dedicated hardware for key matrix decoding. The series typically targets cost-sensitive designs requiring reliable input handling without heavy CPU intervention.

Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation for this specific suffix variant. Evaluate generic I2C GPIO expanders with similar pin counts and voltage ranges only after verifying register compatibility and electrical specifications against the original datasheet.
