ADP5585ACPZ-01-R7

ADP5585ACPZ-01-R7 is a 10 input/output port expander with a built in keypad matrix decoder, programmable logic, reset generator, and PWM generator. Input/output expander ICs are used in portable devices (phones, remote controls, and cameras) and nonportable applications (healthcare, industrial, and instrumentation). I/O expanders can be used to increase the number of I/Os available to a processor or to reduce the number of I/Os required through interface connectors for front panel designs. It handles all key scanning and decoding and can flag the main processor via an interrupt line that new key events have occurred. GPI changes and logic changes can also be tracked as events via the FIFO, eliminating the need to monitor different registers for event changes. It is used in applications such as keypad entries and input/output expansion capabilities, smart phones, remote controls, and cameras, healthcare, industrial, and instrumentation.

• 16-element FIFO for event recording, key press/release interrupts
• GPIO functions, GPI with selectable interrupt level
• GPO with push-pull or open-drain, programmable logic block
• Internal PWM generation, external PWM with internal PWM AND function
• Reset generators, I²C interface with fast mode plus (Fm+) support of up to 1MHz
• Open-drain interrupt output, VDD input voltage range from 1.65V to 3.6V
• Standby current is 1μA typical at (VDD = 1.65V)
