Product Overview: PCA9535CD,112
The PCA9535CD,112 is a robust I/O expander from NXP Semiconductors designed to provide additional I/O capabilities to microcontrollers over an I²C interface. This makes it an ideal choice for applications where additional inputs/outputs are needed but are not available on the microcontroller itself.
Key Features
- 16-bit I/O Expander: The device offers 16 individual I/Os that can be configured either as inputs or outputs, providing significant flexibility in interfacing with various peripherals.
- Low Standby Current: With a low standby current, the PCA9535CD,112 is suitable for battery-powered and power-sensitive applications.
- Interrupt Output: It features an interrupt output which can be connected to the interrupt input of a microcontroller, notifying it of input changes without the need for constant polling.
- I²C Interface: The I²C-bus interface supports standard (100 kHz), fast (400 kHz), and Fast-mode Plus (1 MHz) I²C protocols.
- Address Pins: Three hardware address pins allow up to eight PCA9535 devices on the same I²C-bus, making it possible to expand I/Os up to 128.
- Power Supply Range: It operates from a power supply range of 2.3V to 5.5V, which is compatible with most logic levels and suitable for a variety of operating environments.
