How Does The Expand 15 Click Board™ Work?
The Expand 15 Click Board™ is based on the TCAL6416, a general-purpose I/O expander from Texas Instruments. The TCAL6416 comes in one P-port configuration and allows easy addition of I/O through a standard I2C serial interface. Its digital core consists of 8-bit data registers, allowing users to configure the I/O port characteristics. The I/Os are configured as inputs at Power-On or after a Reset condition. However, the host controller can configure the I/Os as either inputs or outputs by writing to the Configuration registers. The data for each input or output is kept in the corresponding Input Port or Output Port register, with the possibility to invert the polarity of the Input Port with the Polarity Inversion register. The P-port channels configured as outputs can sink up to 25mA for directly driving LEDs, but the current must be limited externally with additional resistance.
Additionally, the TCAL6416 has Agile I/O functionality specifically targeted to enhance the I/O ports, including programmable output drive strength, programmable pull-up and pull-down resistors, latchable inputs, maskable interrupts, interrupt status register, and programmable open-drain or push-pull outputs. These configuration registers improve the I/O by increasing flexibility and allowing users to optimize their power consumption, speed, and EMI design.
This Click board™ communicates with MCU using the standard I2C 2-Wire interface to read data and configure settings with a maximum frequency of 1MHz. Also, the TCAL6416 allows choosing the least significant bits (LSB) of its I2C slave address using the SMD jumper labelled ADDR SEL. It also possesses a general reset signal routed on the RST pin of the mikroBUS™ socket to reset the TCAL6416, and an additional interrupt signal, routed on the INT pin of the mikroBUS™ socket whenever an input port changes state.
The Expand 15 Click Board™ can only be operated with a 3.3V logic voltage level. Additionally, there is a possibility for the TCAL6416 power supply selection via jumper labelled VCCP SEL to supply the TCAL6416 from 1.08V to 3.6V external power supply (V pin) or with 3V3 mikroBUS™ power rail. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. However, the Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.
