Description

Description

The ST16C5801 is a universal asynchronous receiver and transmitter (UART) and is pin compatible with the ST16C550 UART. The 580 is an enhanced UART with 16 byte FIFO's, automatic hardware/software flow control and data rates up to 1.5Mbps. Onboard status registers provide the user with error indications and operational status. Modem interface control is included and can be optionally configured to operate with the Infrared (IrDA) encoder/decoder. The system interrupts may be tailored to meet user requirements. An internal loop-back capability allows onboard diagnostics.

The ST16C580 is available in 40 pin PDIP, 44 pin PLCC, and 48 pin TQFP packages. It is fabricated in an advanced CMOS process to achieve low drain power and high speed requirements.

NOTE: 1Covered by U.S. Patent #5,649,122.
