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.
