GENERAL DESCRIPTION
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. The 2450 is fabricated in an advanced CMOS process capable of operating from 2.97 volt to 5.5 volt power supply. The devices with a top marking of "A2 YYWW" or newer have 5 volt tolerant inputs.FEATURES
