ADP5587ACBZ-R7 Description

Short technical summary and product information.

The ADP5587ACBZ-R7 is a mobile I/O expander and QWERTY keypad controller from Analog Devices. It provides 18 configurable GPIOs that can also be arranged as an 8x10 keypad matrix. Communication is via an I²C interface with clock frequency up to 400 kHz. The device operates from a supply voltage of 1.65V to 3.6V, making it suitable for low-power portable applications. Typical idle current is 1 µA, and polling current is 55 µA. An open-drain interrupt output with level programmability is included, along with a 275 µs debounce time on the reset line and GPIs. Additional features include keypad lock capability, programmable pull-ups, and a key event counter with overflow interrupt. The ADP5587ACBZ-R7 is housed in a 25-UFBGA, WLCSP package (25-WLCSP 1.97x1.97mm) with 0.4 mm lead pitch, designed for surface mount assembly. It operates over a temperature range of -40°C to 85°C.
