The ST16C450 is a universal asynchronous receiver and transmitter. A programmable baud rate generator is provided to select transmit and receive clock rates from 50Hz to 1.5 MHz. The ST16C450 is an improved version of the NS16C450 UART with higher operating speed and lower access time. The ST16C450 on board status registers provides the error conditions, typ.
· Pin to pin and functional compatible to NS16450,VL16C450,WD16C450
· Modem control signals (CTS
*, RTS
*, DSR
*, DTR
*, RI
*, CD
*)
· Programmable character lengths (5, 6, 7, 8)
· Even, odd, or no parity bit generation and detection
· Status report register
· Independent transmit and receive control
· TTL compatible inputs, outputs
· 460.8 kHz transmit/receive operation with 7.372
MHz crystal or external clock source
