ADP5586ACBZ-03-R7

Overview

The ADP5586ACBZ-03-R7 is a keypad decoder and I/O port expander manufactured by Analog Devices. It features ten configurable input/output pins supporting up to a 5x5 matrix keypad. The device includes a 16-element FIFO for event recording, programmable logic blocks, pulse generators, and a reset generator. It communicates via an I2C interface with Fast-mode Plus support up to 1 MHz. Operating voltage ranges from 1.65 V to 3.6 V, with standby current as low as 1 μA at 1.65 V. The component is housed in a 16-ball WLCSP package measuring 1.59 mm × 1.59 mm and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Integrated 16-element FIFO records key press/release, GPI changes, and logic events to reduce processor monitoring overhead.
• Configurable I/Os support general-purpose input/output functions, including selectable pull-up/pull-down resistors and push-pull or open-drain outputs.
• Built-in programmable logic block allows integration of common logic requirements, saving board area and cost.
• Alternate I2C address configuration distinguishes this model variant within the ADP5586 series.

Applications

• Smartphones and mobile devices requiring keypad entry and I/O expansion
• Remote controls and portable consumer electronics
• Cameras and imaging equipment
• Healthcare, industrial, and instrumentation systems

Procurement Notes

Verify the specific ordering suffix ACBZ-03-R7 confirms the alternate I2C address feature set before procurement. Ensure compatibility with the target system's I2C bus addressing scheme. Confirm package availability and lead times through authorized distributors. Check RoHS compliance documentation for regulatory adherence. Validate that the 1.65 V to 3.6 V supply range matches the application power design.

Selection Notes

Select this part when an alternate I2C address is required to avoid conflicts on the bus. The 5x5 matrix capability suits applications needing up to 25 keys. Consider the 16-event FIFO depth for burst activity scenarios. Evaluate the 1.59 mm × 1.59 mm WLCSP footprint for space-constrained designs. Compare standby current specifications against battery life requirements.

Part Context

This component belongs to the ADP5586 family of I/O expanders. The ACBZ-03-R7 variant specifically offers an alternate I2C address (0x30) compared to other models like the ACBZ-01-R7 which adds a sixth row. All variants share the same core functionality, package, and electrical characteristics. The R7 suffix indicates reel packaging for automated assembly.

Replacement Considerations

Direct substitutes include other ADP5586 variants such as ADP5586ACBZ-00-R7 or ADP5586ACBZ-01-R7 if the alternate I2C address is not critical. Verify pin compatibility and register map consistency. Ensure the replacement supports the required keypad matrix size and I/O configuration needs.
