PCAL9722HN-ARD

PCAL9722HN-ARD is an ultra low-voltage translating 22-bit SPI I/O expander with Agile I/O features, interrupt output and reset evaluation board. The NXP analog product development boards provide an easy-to-use platform for evaluating NXP products. The boards support a range of analog, mixed-signal and power solutions. They incorporate monolithic integrated circuits and system-in-package devices that use proven high-volume technology. NXP products offer longer battery life, a smaller form factor, reduced component counts, lower cost and improved performance in powering state-of-the-art systems. Suitable for consumer (battery-powered mobile) and industrial (Keypad) applications.
