Introduction to SP481EEP-L Interface - Drivers, Receivers, Transceivers

The SP481EEP-L is an integrated, low power, full-duplex transceiver designed for low voltage, low I/O count applications. It provides a versatile, cost-effective interface solution for both full-duplex and half-duplex systems and includes both a transmitter and receiver. This device typically operates at 3.3 volts, but can be easily configured to operate at lower voltages when needed.

Application Field

The SP481EEP-L is an ideal solution for providing a low-cost, low-power, full-duplex serial interface between two system devices. It is capable of transmitting and receiving data at high speeds up to 10 Mbits/sec. It is also an ideal choice for low pin count applications or applications with confined board spacings. It can be used in a variety of applications such as field bus, industrial control, point-of-sale, remote terminal, systems interfacing, and networking.

Working principle

The SP481EEP-L is designed to operate in either full-duplex, or half-duplex mode. In full-duplex mode, data is simultaneously transmitted from the transmitter and received by the receiver. When performing half-duplex communication, the device works as either a transmitter or a receiver. In this mode, the device can only transmit or receive data, but cannot do both simultaneously.The SP481EEP-L supports two-wire and four-wire communication modes. In two-wire mode, the same two wires are used to transmit and receive data. In four-wire mode, two wires are used to transmit data, while the other two wires are used to receive data. This allows for easier implementation when dealing with complex systems or applications.The SP481EEP-L supports data frame formats such as character-oriented asynchronous and bit-oriented synchronous modes. CharacterOriented asynchronous mode allows up to 8 data bits to be transmitted per frame, while Bit-Oriented synchronous mode allows up to 11 data bits to be transmitted per frame.The device operates from a single 3.3 V supply with a power dissipation of less than 300 mW and a standby current of less than 0.3 mA. It also supports a wide range of speeds from 300 bps to 10 Mbps.

Conclusion

The SP481EEP-L provides a low-cost, low-power, full-duplex serial interface solution for both full-duplex and half-duplex systems. It is designed to operate from a single 3.3 V supply and provides data rates up to 10 Mbps. It supports a wide range of data modes including character-oriented asynchronous and bit-oriented synchronous modes. It is ideal for low pin count applications or applications with confined board spacings.
