The ST16C2450 is an improved version of the NS16450 UART with higher operating speed and lower access time. The Obsolescence DAN-108, UART Crystal 2450 provides enhanced UART functions with a modem control interface, Oscillator Design Guide and data rates up to 1.5Mbps. Onboard status registers provide the user Interface Version 1.0.0 with error indications and operational status. Brochure March 2000 58.16 KB IBIS Models System interrupts and modem control features may be tailored by external software to meet specific user requirements. An internal loop-back BSDL capability allows onboard diagnostics. Independent programmable baud rate generators are provided to select transmit and receive clock rates ICI from 50 Bps to 1.5 Mbps. The Baud rate generator can be configured for either crystal or external clock input. UART Finder The 2450 is available in a 40-pin plastic-DIP, 44-pin PLCC, and 48-pin ST16C2450 -Dual UART with Higher Operating Speed and Lower Access Time Quality and TQFP packages. The 2450 is fabricated in an advanced CMOS process to AN-2450/AN-2550 - ST16C2450 Reliability achieve low drain power and high speed requirements. and ST16C2550 Application Example For UART technical support or to obtain an IBIS model for this product, Version 1.0.0 Quality & please email Exar s UART Technical Support group.
