ADP5585ACPZ-03-R7

Overview

The ADP5585ACPZ-03-R7 is a keypad decoder and I/O expander manufactured by Analog Devices Inc. It features 10 configurable input/output pins capable of supporting a 5x5 matrix keypad or general-purpose I/O expansion. The device operates on a supply voltage ranging from 1.65 V to 3.6 V with an operating temperature range of -40°C to +85°C. It communicates via an I2C interface supporting fast mode plus at frequencies up to 1 MHz. Key specifications include a standby current of 1 µA, an operating current of approximately 80 µA during key scanning, and push-pull outputs with a 10 mA sink capability. The component is housed in a 16-lead LFCSP package.

Feature Summary

• Integrated event FIFO for recording up to 16 key press/release and logic events
• Built-in programmable logic block and PWM generator functions
• Configurable internal pull-up (100 kΩ/300 kΩ) and pull-down (300 kΩ) resistors
• Alternate I2C address configuration for system bus flexibility

Applications

• Keypad entries and input/output expansion in portable devices
• Smart phones, remote controls, and cameras
• Healthcare, industrial, and instrumentation equipment

Procurement Notes

Verify the specific ordering suffix to confirm the alternate I2C address feature set. Ensure the LFCSP-16 package matches the target PCB footprint. Confirm RoHS compliance status through official manufacturer documentation prior to final procurement decisions.

Selection Notes

Select this model when an alternate I2C address is required to resolve bus conflicts. Compare against standard variants if default addressing suffices. Consider the WLCSP option if board space constraints are critical, noting the pinout differences between package types.

Part Context

This component belongs to the ADP5585 series of I/O expanders. It shares core functionality with models like the ADP5585ACPZ-00-R7 but differs in its I2C addressing configuration. The series supports various keypad matrix sizes and GPIO configurations across different package options.
