OX16C954 General Description
The OX16C954 is a single chip solution for 4 channel serial add-in cards. Each UART channel in the OX16C954 offers data rates up to 15Mbps and 128-byte deep transmitter and receiver FIFOs. Deep FIFOs reduce CPU overhead and allow utilisation of higher data rates.
Each UART channel is software compatible with the widely used industry-standard 16C550 devices and compatibles, as well as the OX16C95x family of high performance UARTs. It is pin-compatible with the TL16C554, ST16C654 devices.
In addition to increased performance and FIFO size, the UARTs also provide the full set of OX16C95x enhanced features. These include improved flow controls such as automated software flow control using Xon/Xoff and automated hardware flow control using CTS#/RTS# and DSR#/DTR# to prevent FIFO over-run.
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 OX16C954 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 OX16C954 is ideally suited to PC applications, such as high-speed multi-port add-in cards that 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.
Fabricated in 0.6mm process, OX16C954 also has a low operating current and sleep mode for battery powered applications.
