The 155X is an Oscillator Design Guide improved version of the SSI 73M1550 and SSI 73M2550 UART with higher Interface operating speed and lower access time. The 155X provides enhanced Version 1.0.0 Brochure UART functions with 16 byte FIFOs, a modem control interface, March 2000 independent programmable baud rate generators with clock rates to 1.5 58.16 KB IBIS Models Mbps. BSDL Onboard status registers provide the user with error indications and ICI operational status. System interrupts and modem control features may be tailored by external software to meetspecific user requirements. An internal UART Finder loopback capability allows onboard diagnostics. The 155X is available in a 28-pin PLCC/plastic-DIP, 48-pin TQFP packages. ST16C1550 -UART with 16-Byte FIFOs Quality and The Baud rate generator can be configured for either crystal or external AN-1450/AN-1550, ST16C1450 Reliability clock input with the exception of the 28 pin 1551 package. and ST16C1550 Application Example An external clock must be provided for the 28 pin 1551 package. Each Version 1.0.0 Quality & package type, with the exception of the 28 pin 1550, provides a buffered December 1996 Reliability reset output that can be controlled through user software. DMA monitor Homepage 43.29 KB signals TXRDY/RXRDY are not available at the 155X I/O pins but these signals are accessible through ISR register bits 4-5. Except as listed Material General UART Application Note above, each package version has the same features. The 155X is Declaration Version 1.0.0 functionally compatible with the 16C550. The 155X is fabricated in an Sheets December 1996 advanced CMOS process to achieve low drain power and high speed requirements. 39.81 KB Quality Manual For UART technical support or to obtain an IBIS model for this product, please email Exar s UART Technical Support group.
