The PCA9670D,512 from NXP Semiconductors is a general-purpose remote I/O expander that utilizes the two-wire I2C-bus interface. It provides eight quasi-bidirectional ports, enabling expansion of I/O capabilities in embedded systems.
This device features a 1 MHz I2C-bus interface supporting Fast-mode Plus, with SDA offering a 30 mA sink capability. The operating supply voltage ranges from 2.3 V to 5.5 V, and the I/Os are 5.5 V tolerant. It includes eight remote I/O pins that default to inputs at power-up. The latched outputs have a 25 mA sink capability, suitable for directly driving LEDs, with a total package sink capability of 200 mA.
The PCA9670D,512 operates within a temperature range of -40°C to +85°C. It has an active LOW reset input and supports up to 64 devices on the same I2C-bus through three hardware address pins, allowing for up to 512 I/Os. The device also features a low standby current of 2.5 µA typical.
It is available in a 16-SOIC package and is designed for surface mounting. Applications include LED signs and displays, keypads, industrial control, and mobile devices.
