This is the PCF8574AP consists of an 8-bit quasi-bidirectional port and an i2C Serial Bus Interface. The PCF8574AP has a low current consumption and includes latched output with HIGH consumption and include latched output with high current drive capability for
How to Place/Connect a Pull Up Resistors on Chip
A pull up resistor is a resistor that works the chip normally HIGH and change it to LOW when switched on, Pull-Up or Pull-Down resistor mostly they are connected to the pins of the chip so that they can define
How I2C/I²C Serial Bus Communication Protocol Works?
Who develop I²C? In early 1980’s PHILIPS designed & develop a new type of BUS standard named I2C for easy communication between integrated circuits especially in TV circuits, which exist on the circuit board. The name I²C translates intro (Integrated
How SPI, QSPI Serial to Peripheral Interface Woks ?
The SPI(Serial to Peripheral Interface) develop by Motorola and later adopted by Microwire of National Semiconductor and other companies. SPI is a hardware / firmware communication protocol or sometimes Engineers called it a “four wire serial bus” communication. The SPI
