SB16C1054 Quad UART IC

Manufacturer: SystemBase

Price: $9.95

SB16C1054 is a QUAD UART (Universal Asynchrous Receiver/Transmitter) with 256-byte FIFOs, automatic hardware/software flow control, and data rates up to 5 Mbps.

256-byte FIFOs reduce CPU overhead and allow higher data rates and data throughput.

In addition to increased FIFO size and data rates, SB16C1054 also offers enhanced features. It has a GICR (Global Interrupt Control Register)/GISR(Global Interrupt Status Register) that reduces interrupt signal control logic. Also, FUR (Flow control Upper Threshold Register)/FLR(Flow control Lower Threshold Register) that stores receive FIFO threshold levels to start/stop transmission during hardware and software flow control. SB16C1054 allows Xoff re-transmit function as well as Xon any character function in flow control operation. On-chip status registers provide transmission status and all of error-related information (parity, overrun, framing or break interrupt). An internal loop-back capability allows on-board diagnostics.

SB16C1054 is available in plastic TQFP80 and PLCC68 packages.
