This document introduces the OXCF950 series products from Oxford Semiconductor, which is a single-channel full-duplex asynchronous communication chip. It has a 128-byte deep transmitter/receiver FIFO and is fully compatible with industry standard 16C550 type UARTs. It supports multiple data framing formats, readable FIFO levels, and automated in-band flow control. The product features low power consumption, extended temperature range, and various packaging options.
The OXCF950 rev B is a low‑cost, asynchronous 16‑bit PC‑Card/CF UART driver with extended temperature range and low‑power CMOS operation. It supports 3.3 V operation, 5 V tolerant I/O, and offers 128‑byte deep FIFOs for high‑speed data transfer up to 15 Mbps.
This datasheet provides a block diagram, pin information, configuration and operation details, EEPROM specifications, and electrical characteristics. It also lists differences from the original OXCF950, package options, and contact information for Oxford Semiconductor.
