ADP5586ACBZ-01-R7

Overview

The ADP5586ACBZ-01-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 6-row by 5-column matrix. The device includes a 16-element FIFO for event recording, programmable logic blocks, pulse generators, and a reset generator. It operates on a supply voltage range of 1.65 V to 3.6 V with a standby current as low as 1 µA. Communication is handled via an I2C interface supporting Fast-mode Plus speeds up to 1 MHz. The component is housed in a 16-ball WLCSP package measuring 1.59 mm × 1.59 mm.

Feature Summary

• Integrated 16-element FIFO records key press/release events, GPI changes, and logic activity to reduce processor monitoring overhead.
• Configurable I/O structure supports general-purpose input/output functions with selectable internal pull-up or pull-down resistors.
• Built-in programmable logic block allows integration of common logic requirements, saving board area and cost.
• Supports keypad scanning for matrices up to 6 rows by 5 columns with automatic ghosting prevention and debounce filtering.

Applications

• Smartphones and mobile devices requiring keypad entry and I/O expansion
• Remote controls and cameras with limited processor I/O resources
• Healthcare equipment and industrial instrumentation systems

Procurement Notes

Verify the specific ordering suffix -01-R7 to confirm the inclusion of Row 5 functionality and the default GPIO configuration. Ensure compatibility with the target I2C bus voltage levels and check for any regional distribution restrictions before finalizing procurement plans.

Selection Notes

Select this model specifically when a 6-row keypad matrix is required, as other variants in the series support only 5 rows. Confirm that the WLCSP-16 package dimensions fit the PCB layout constraints. Verify that the operating temperature range of -40°C to +85°C meets the environmental requirements of the application.

Part Context

This component belongs to the ADP5586 series of interface ICs designed for portable and non-portable applications. It serves as an alternative to discrete logic solutions for keypad decoding and I/O expansion. The series includes variants with different I2C addresses and startup configurations to suit diverse system designs.

Replacement Considerations

Direct substitutes within the same family include the ADP5586ACBZ-00-R7 and ADP5586ACBZ-03-R7. Note that these alternatives lack the additional Row 5 pin available on the -01 variant and may have different default I2C addresses or GPIO states upon power-up.
