ST16C550中文资料UART With 16-Byte FIFOs数据手册MaxLinear规格书

描述 Description

The ST16C550 is a universal asynchronous receiver and transmitter with 16-byte transmit and receive FIFO. A programmable baud rate generator is pro- video to select transmit and receive clock rates from 50bps to 1.5Mbps.
The ST16C550 is an improved version of the NS16C550 UART with higher operating speed and lower access time. The ST16C550 onboard status registers provides the error conditions, type and status of the transfer operation being performed. Included is complete MODEM control capability and a processor interrupt system that may be software tailored to the user’s requirements. The ST16C550 provides internal loop-back capability for onboard diagnostic testing.
The ST16C550 is available in 40-pin PDIP, 44-pin PLCC and 48-pin TQFP packages. It is fabricated in an advanced 0.6m CMOS process to achieve low drain power and high speed requirements.
