The ADP5587ACBZ-R7 is a robust, versatile keypad and I/O expander IC brought to you by Analog Devices Inc., a leader in high-performance semiconductors. This integrated circuit is designed to facilitate the interfacing of additional I/Os and keypads to a main processor, extending its capabilities without the need for redesigning the core processor architecture. The ADP5587ACBZ-R7 is particularly useful in mobile devices, consumer electronics, and industrial control panels where space is at a premium and functionality is key.

Key Features

• I/O Expansion: Offers 10 GPIOs (General Purpose Input/Output) which can be configured as keypad matrix of up to 8x8, providing up to 64 keys.
• Interrupt Function: Features an interrupt output that signals the host processor when a key press or GPIO event occurs, ensuring prompt response to user inputs.
• Event FIFO: Integrates a 16-event FIFO buffer to store keypress and GPIO events, reducing the risk of missing any user interaction.
• On-Chip GPI Debouncing: Includes built-in debouncing for GPIs, enhancing the reliability of signal interpretation and reducing the need for external components.
• Low Power Consumption: Designed for power-sensitive applications, it supports a low-power mode to conserve energy when not actively scanning the keypad or monitoring GPIOs.
• Easy Communication: Communicates with the main processor via a standard I2C interface, simplifying integration and reducing the number of wires needed for connectivity.

Applications

• Mobile devices such as smartphones and tablets
• Consumer electronics including remote controls and gaming devices
• Industrial control panels and automation systems
• Portable instrumentation and medical devices

Product Specifications
