Product Summary
The ST16C2450CQ48 is a dual universal asynchronous receiver and transmitter (UART). The ST16C2450CQ48 is an improved version of the ST16C2450 with lower operating voltage and 5 volt tolerant inputs. The ST16C2450CQ48 provides enhanced UART functions, a modem control interface and data rates up to 1.5 Mbps. Onboard status registers provide the user with error indications and operational status. Independent programmable baud rate generators are provided to select transmit and receive clock rates up to 1.5 Mbps. An internal loopback capability allows onboard diagnostics. The ST16C2450CQ48 is available in a 44- pin PLCC and 48-pin TQFP packages. The ST16C2450CQ48 is fabricated in an advanced CMOS process capable of operating from 2.97 volt to 5.5 volt power supply.
