UART WITH 16-BYTE FIFO’s AND
INFRARED (IrDA) ENCODER/DECODER
GENERAL 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 580 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.
