The ADP5589ACBZ-01-R7 from Analog Devices is a versatile I/O expander designed for applications needing enhanced input/output capabilities and keypad decoding. It features 19 configurable I/O pins, allowing for flexible system design.
The device includes a built-in keypad matrix decoder that supports matrices up to 11x8, simplifying keypad integration. It communicates via an I2C interface, supporting fast-mode plus up to 1 MHz, which is ideal for efficient data transfer in embedded systems. A 16-element FIFO buffer is integrated for event recording, capturing key press/release events, GPI changes, and logic changes, thereby reducing the burden on the main processor.
With a configurable operating voltage range of 1.65V to 3.6V, the ADP5589ACBZ-01-R7 is suitable for a wide array of portable and non-portable devices. It offers programmable pull-up and pull-down resistors, dual programmable logic blocks, a reset generator, and a PWM generator, providing extensive functionality within a compact package.
The ADP5589ACBZ-01-R7 is supplied in a 25-ball WLCSP (Wafer Level Chip Scale Package) measuring 1.99 mm x 1.99 mm, making it suitable for space-constrained designs. It is designed for surface mount applications.
The ADP5589ACBZ-01-R7 operates from 1.65V to 3.6V.
It is available in a 25-WLCSP (1.99x1.99 mm) package for surface-mount mounting.
The part is listed as RoHS3 Compliant, but this information is unverified and should be confirmed with official documentation.
The I2C interface supports fast-mode plus (Fm+) with speeds up to 1 MHz.
It has 19 configurable I/Os.
It supports keypad matrices up to 11 rows by 8 columns.
Yes, it features selectable 100 kΩ or 300 kΩ pull-up resistors and 300 kΩ pull-down resistors.
