The XR16C2450 is an improved version of the XR16C2450 with lower operating voltage and 5 volt tolerant inputs. The 2450 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 2450 is available in a 44pin PLCC and 48-pin TQFP packages.
