SB16C1058 is an 8-channel UART (Universal Asynchronous Receiver Transmitter) controller with a built-in 256-byte transmit/receive FIFO, supporting communication speeds of up to 5.3Mbps. It provides an Auto Toggle function that controls automatic input/output switching at the hardware level for RS422 and RS485 communication. By leveraging the 256-byte transmit/receive FIFO, SB16C1058 not only reduces CPU overhead but also enables fast processing of large volumes of data.
The powerful, enhanced functionality of SB16C1058 can be easily applied across a wide range of fields and applications. SB16C1058 delivers excellent efficiency even in high-speed data communication through features such as a 256-byte FIFO and effective interrupt management. It also reduces system load during multi-channel communication, enabling more efficient system operation overall. For further details, please refer to the SB16C1058 datasheet.
SB16C1058 has a built-in 256-byte FIFO that helps prevent excessive CPU access, reducing overall system load. A variety of FIFO configuration registers, including FCR, AFR, TTR, and RTR, allow settings to be tailored to a wide range of applications. For further details, please refer to the SB16C1058 datasheet.
SB16C1058 consists of 8 UARTs, with a dedicated internal INT assigned to each UART, and offers a variety of interrupt configuration options. To make efficient use of the 8 internal UART interrupts together with a single external Global interrupt line, SB16C1058 provides interrupt management registers such as GISR, GICR, ISR, and IER, allowing convenient access to useful functions like interrupt polling and masking. For further details, please refer to the SB16C1058 datasheet.
Xon/Xoff is a software flow control method that starts and stops data transmission using mutually agreed Xon/Xoff characters sent over the signal line. SB16C1058 supports the Xon/Xoff software flow control function, and registers such as XON, XOFF, and XRCR allow flow control to be managed automatically. It also includes a feature that automatically retransmits the Xoff character if data continues to be received after Xoff has been sent. In addition, an Xon-any feature is supported, which resumes transmission upon receiving any character, not just the designated Xon character. For further details, please refer to the SB16C1058 datasheet.
RTS/CTS are hardware flow control signal lines that start and stop transmission based on the RTS/CTS signal states. The Auto-RTS function automatically controls the output of the RTS pin, which governs the other device's transmission, based on the configured receive FIFO level, while the Auto-CTS function monitors the CTS input and automatically starts or stops transmission according to the other device's RTS flow control request. Related registers such as FSR and EFR provide convenient access to a variety of useful flow control functions. For further details, please refer to the SB16C1058 datasheet.
