Data Sheet FEATURES 18-GPIO port expander or 10 × 8 keypad matrix GPIOs configurable as GPIs, GPOs, and keypad rows or columns I2C interface with auto-increment 1.65 V to 3.6 V operation Keypad lock capability Open-drain interrupt output Key press and key release interrupts GPI interrupt with level programmability Programmable pull-ups Key event counter with overflow interrupt 275 μs debounce on the reset line and GPIs 1 μA typical idle current 55 μA typical polling current 4 mm × 4 mm LFCSP package Small 2 mm x 2 mm WLCSP package, 0.4 mm pitch Multiple I2C addresses available for the LFCSP package to allow multiple port expanders on the same bus APPLICATIONS Keypad and I/O expander designed for QWERTY type phones that require a large keypad matrix GENERAL DESCRIPTION The ADP5587 is an I/O port expander and keypad matrix designed for QWERTY type phones that require a large keypad matrix and expanded I/O lines. I/O expander ICs are used in mobile platforms as a solution to the limited number of GPIOs available in the main processor. In its small 2 mm × 2 mm package, the ADP5587 contains enough power to handle all key scanning and decoding and to flag the processor of key presses and releases via the I2C interface and interrupt. The ADP5587 frees the main microprocessor from the need to monitor the keypad, thereby minimizing current drain and increasing processor bandwidth. The ADP5587 is also equipped with a buffer/FIFO and key event counter to handle and keep track of up to 1.
