SN65C3222EPWRG4 Application Field and Working Principle
SN65C3222EPWRG4 is an integrated circuit driver/receiver pair that is able to implement a cost-effective, full-duplex RS-485 serial link up to 1 Mbps. This transceiver has been designed using the latest CMOS technology, combined with careful circuit design, to provide reliable communications in noisy environments.
Application Field
This chip is often used in medical instruments and industrial automation systems, where reliable, cost-effective communications are critical. Additionally, SN65C3222EPWRG4 can be used in factory automation systems, control applications, home automation systems and point of sale systems.
Working Principle
The device works as a transmit/receive pair that contains driver and receiver blocks. The driver block consists of two stages. The first stage is an output buffer for the master transceiver, while the second stage is a differential line driver. The receiver block consists of a differential line receiver, followed by a levelshifter stage. Additionally, the receiver incorporates a fail-safe circuit, which ensures that any idle lines remain in logic "1" to indicate that no transmission is taking place.
The transmitter and receiver blocks are implemented with a low power CMOS logic circuit. This allows the chip to minimize power consumption and improve noise immunity. Additionally, the use of shielded terminals provides improved EMC performance by keeping noise generated by the device to a minimum.
The SN65C3222EPWRG4 is designed to be pin-compatible with the industry-standard RS-485 interface. This makes for easy migration from existing systems. The chip is available in a SOIC-14 package and operates from a single 5V supply. The device is rated for up to 1 Mbps data rates and is capable of handling data transmission up to 4000 feet.
