OX16C950B中文资料OXFORD数据手册PDF规格书

The OX16C950B is a single-channel ultra-high performance UART offering data rates up to 15Mbps and 128-deep transmitter and receiver FIFOs. Deep FIFOs reduce CPU overhead and allow utilisation of higher data rates.

It is software compatible with the widely used industry standard 16C550 type devices and compatibles, as well as other OX16C95x family devices. It is pin-compatible with the TL16C550B/C, TL16C750 and ST16C650 devices.
