SC16IS762IPW

The SC16IS762IPW is a highly integrated, low-power I2C/SPI to UART bridge from NXP Semiconductors, designed to facilitate communication between microcontrollers and various serial devices. This device is particularly useful in applications where a microcontroller needs to communicate with multiple UART devices over a single I2C or SPI bus, thereby reducing the number of required GPIO pins.

Key Features:

1. Communication Interfaces:

   • UART: The SC16IS762IPW supports a full-duplex UART interface with a maximum baud rate of 5 Mbps. It can handle standard UART features such as 5 to 8 data bits, even/odd/none parity, and 1 or 2 stop bits.
   • I2C/SPI: The device can operate as an I2C slave with a maximum clock frequency of 1 MHz or as an SPI slave with a maximum clock frequency of 30 MHz, allowing for flexible integration into various systems.

2. Integrated FIFO:

   • The SC16IS762IPW includes a 64-byte transmit FIFO and a 64-byte receive FIFO, which helps to minimize CPU overhead and allows for smoother data transmission and reception.

3. Addressing and Configuration:

   • The device supports up to 256 different I2C addresses, making it suitable for multi-device configurations. It can be configured through registers accessible via the I2C or SPI interface.

4. Power Management:

   • The SC16IS762IPW is designed for low power consumption, making it ideal for battery-operated devices. It features a sleep mode that significantly reduces power usage when the device is not in active communication.

5. Interrupt Handling:

   • The device provides interrupt outputs for various events, such as data received, transmit FIFO empty, and error conditions, allowing the host microcontroller to respond promptly to changes in communication status.

6. Error Detection:

   • It includes built-in error detection mechanisms, such as framing errors, overrun errors, and parity errors, which help ensure reliable data transmission.

7. Package and Pin Configuration:

   • The SC16IS762IPW is available in a 28-pin TSSOP package, which is compact and suitable for space-constrained applications. The pin configuration includes dedicated pins for power, ground, I2C/SPI communication, and UART signals.

Applications:

The SC16IS762IPW is well-suited for a variety of applications, including:

• Industrial automation systems
• Consumer electronics
• Medical devices
• Automotive applications
• Remote sensor networks

Conclusion:

Overall, the SC16IS762IPW from NXP Semiconductors is a versatile and efficient solution for bridging I2C/SPI and UART communications. Its combination of high-speed data transfer, low power consumption, and robust error handling makes it an excellent choice for modern embedded systems requiring reliable serial communication.
