XR16C2450 Dual UART with Higher Operating Speed and Lower Access Time
The XR16C2450 (2450) is a dual universal asynchronous receiver and transmitter (UART). The XR16C2450 is an improved version of the NS16450 UART with higher operating speed and lower access time. The 2450 provides enhanced UART functions with a modem control interface, and data rates up to 1.5Mbps. Onboard status registers provide the user with error indications and operational status. System interrupts and modem control features may be tailored by external software to meet specific user requirements. An internal loop-back capability allows onboard diagnostics. Independent programmable baud rate generators are provided to select transmit and receive clock rates from 50 Bps to 1.5 Mbps. The Baud rate generator can be configured for either crystal or external clock input. The 2450 is available in a 40-pin plastic-DIP, 44-pin PLCC, and 48-pin TQFP packages. The 2450 is fabricated in an advanced CMOS process to achieve low drain power and high speed requirements
