ADP5585ACPZ-00-R7

Overview

The ADP5585ACPZ-00-R7 is a keypad decoder and I/O expander manufactured by Analog Devices Inc. It features 10 configurable input/output pins supporting keypad matrix decoding up to 5 × 5, general-purpose I/O expansion, PWM generation, programmable logic blocks, and reset generators. The device operates on a supply voltage range of 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. The component is housed in a 16-lead LFCSP package measuring 3 mm × 3 mm.

Feature Summary

• Integrated event FIFO for recording key presses, releases, and GPI changes
• Configurable I/Os supporting keypad decoding, GPIO expansion, and PWM generation
• Built-in programmable logic blocks and dual reset generators
• I2C interface with open-drain interrupt output capability

Applications

• Keypad entries and input/output expansion capabilities
• Smart phones, remote controls, and cameras
• Healthcare, industrial, and instrumentation

Procurement Notes

Verify the specific ordering suffix to confirm package type and feature set. The ADP5585ACPZ-00-R7 variant utilizes the LFCSP package. Confirm compatibility with system voltage levels and I2C bus requirements before integration. Ensure proper thermal management due to power dissipation limits specified in the datasheet.

Selection Notes

Select this model when a 5 × 5 keypad matrix or 10-channel GPIO expansion is required without additional row pin functionality. Compare against the ACBZ-01-R7 variant if Row 5 support is needed. Verify that the LFCSP package fits the PCB footprint constraints. Check I2C address configuration needs as this model uses the default address.

Part Context

The ADP5585 belongs to a family of keypad decoders and I/O expanders from Analog Devices. Variants include WLCSP packages (ACBZ) and different feature sets defined by suffixes like -00, -01, and -02. The ACPZ suffix denotes the Lead-free LFCSP package option within this product line.
