Deep FIFOs reduce CPU overhead and allow utilisation of higher data rates. It is software compatible with the widely used industrystandard 16C550 type devices and compatibles, as well as other OX16C95x family devices. It is pin-compatible with the TL16C550B/C, TL16C750 and ST16C650 devices. In addition to increased performance and FIFO size, the OX16C950B also provides enhanced features including improved flow control. Automated software flow control using Xon/Xoff and automated hardware flow control using CTS#/RTS# and DSR#/DTR# prevent FIFO overrun. Flow control and interrupt thresholds are fully programmable and readable, enabling programmers to fine-tune the performance of their system. FIFO levels are readable to facilitate fast driver applications. The addition of software reset enables recovery from unforeseen error conditions allowing drivers to restart gracefully. The OX16C950B supports 9-bit data frames used in multi-drop industrial protocols. It also offers multiple external clock options for isochronous applications, e.g. ISDN, xDSL. The OX16C950B is ideally suited to PC applications, such as high-speed COM port add-in cards which enable PC users to take advantage of the maximum performance of analogue modems or ISDN terminal adapters. It is also suitable for any equipment requiring high speed RS232/RS422/RS485 interfaces. The OX16C950B also has a low operating current and sleep mode for battery powered applications.
