The AT83C21GC144-Z1RUL is an interface dedicated to the industry leading CAN bus controllers. This device is compatible with CAN buses that use two wire connections and are based on a CAN protocol like CAN FD and CAN 2.0B. It is designed to provide a powerful interface with the controller and allow the user to access and control various information, such as real-time data, status indicators, and alarms. With a minimum operating voltage of 5V, it is suitable for a wide range of applications including automotive, industrial, and medical.

The AT83C21GC144-Z1RUL has a unique low-power design that makes it well-suited for areas that require low-voltage signals. As a result, the device has a low standby current consumption of around 4µA, making it ideal for battery-powered applications. The onboard EEPROM can store up to 42 bytes of data and is used for storing the configurations and parameters of the device. The AT83C21GC144-Z1RUL can be quickly and easily reconfigured using the I2C bus.

The AT83C21GC144-Z1RUL has two transceiver channels that can be set to support either standard or extended frame formats. The device supports baud rates up to 1Mbaud and a wide range of data rates, ranging from 125 kHz to 1 MHz. When transmitting data, the AT83C21GC144-Z1RUL can issue an interrupt that is triggered when certain conditions are met. This helps to improve the system responsiveness and provide more efficient CAN bus communication.

The AT83C21GC144-Z1RUL also supports four error detection and correction algorithms. These algorithms can detect errors in the received messages and can provide correction for most of them. The four error detection and correction algorithms are Bit Stuffing, CRC, Parity, and Difference.

The main features of the AT83C21GC144-Z1RUL include a Dedicated Chip Select input and four General Purpose Input and Output pins. The Dedicated Chip Select input allows the device to be connected directly to an external CAN bus and the four General Purpose Input and Output pins allow interfacing with additional external devices. The GPIOs are also programmable, meaning they can be configured to operate in various modes, such as Digital Input Mode, Digital Output Mode and PWM Output Mode.

The AT83C21GC144-Z1RUL is a powerful and versatile CAN bus controller designed to provide a simple and intuitive interface between CAN bus controllers and external devices. With its wide range of data rates, error detection and correction algorithms, and powerful GPIOs, it is well-suited for a wide range of embedded systems applications, from automotive and industrial to medical.
