SN65C3223EPW is an ideal quad-channel low power and low-profile transceiver widely used in the application-field of applications and automotive interfaces. This device offers a full-duplex, connect-and-play based FET data frame, with an extended power range for communication links incorporating USB, CANbus, and RS-232, CAN2.0, etc. and supports up to 8 Mbps data transmission rate. It is designed and fabricated using small size packages maximizing circuit integration and signal integrity.

The receiver portion of the SN65C3223EPW contains 4 channels, 4 receivers, and a fail-safe signal conditioning receiver that runs at 3.3V/1.8V. The quad receivers use a low threshold voltage for logic-high outputs and can detect input signals that are both dynamic and static. The data signal receiver is connected to the SN65C3223EPW’s THV and USIC expandable interfaces. The USIC-compliant transceiver facilitates the replacement of the SIP, Toggler, and FIP transceivers in existing systems.

The SFK1 options enable the SN65C3223EPW for full- or half-duplex with data frame lock reception. The SFK1 supports an extended power range and also supports a CAN2.0 data frame lock function. This function autonomously adjusts the baud rate, allowing it to be used in higher-speed networks while maintaining signal integrity. In addition, the SFK1 supports bi-directional, half-duplex operation, so it is fully compatible with existing RS-232 networks.

The SN65C3223EPW also incorporates a fault-masking circuit. This on-chip circuit ensures the robustness of the device by preventing sudden bursts of noise, glitches, and spike transients, which could otherwise affect network performance. Furthermore, the device provides 2x Clock edge synchronization (CES) on its THV and USIC interfaces, allowing for cascade connections with other devices in harsh application environments. The device features an average power management system, enabling very low power operation as well as compliance to arbitrary frame rate requirements.

The power supply range for the SN65C3223EPW for RS-232 applications is typically 4.5V to 5V, with the USIC interface operating from a 2.5V to 3.3V supply voltage. The THV interface operates from 3.3V to 5V supply voltages. The receiver is designed to operate on the same supply voltage as the transmitter. The device can handle ESD voltages up to ± 25kV and EMB voltages up to 20VPP. The device has an average current consumption of less than 30 mA over a temperature range of -40°C to +125°C.

The SN65C3223EPW can be used in a number of different applications such as industrial, consumer, automotive, and medical. It can also be used in appliance controllers, home automation systems, PLC controllers, and machine vision systems. Furthermore, it can be used in battery-powered and head-end applications such as cellular phones, PDAs, and POS systems.

In summary, the SN65C3223EPW is an ideal low power and low-profile transceiver for multipurpose applications of CANbus, RS-232, CAN2.0, and USB. It offers full-duplex, connect-and-play based FET data frame, with an extended power range and supports up to 8 Mbps data transmission rate. The receiver contains four channels, four receivers, and a fail-safe signal conditioning receiver with an extended power range. In addition, the on-chip fault-masking circuit ensures robustness and reliability of the device. Furthermore, the device features low current consumption and has a wide power supply range for various applications.
