The parallel 58.16 KB port is designed such that the user can configure it as general purpose I/O IBIS Models interface, or for connection to other printer devices. DAN-136, Exar s ST16C452 BSDL and ST16C552 Compared to The 552/552A provides enhanced UART functions with 16 byte FIFOs, a Texas Instruments TL16C452 ICI modem control interface, and data rates up to 1.5Mbps. Onboard status Version 1.0.0 registers provide the user with error indications and operational status. June 2002 UART Finder The system interrupts and control may be tailored to meet user 25.00 KB requirements. An internal loop-back capability allows onboard diagnostics. ST16C552 -Dual UART With 16-Byte FIFO and Parallel Printer Port A programmable baud rate generator is provided to select transmit and AN-452, ST16C452 Application receive clock rates from 50 bps to 1.5 Mbps. Quality and Example Reliability Version 1.0.0 The 552/552A is available in a 68 pin PLCC package. The 552/552A is December 1996 compatible with the 16C450 and 16C550. The difference between the 50.62 KB Quality & ST16C552 and ST16C552A is the logic state of the printer port, INTP Reliability interrupt. The INTP interrupt is active high (logic 1) on the ST16C552 General UART Application Note Homepage whereas INTP is active low (logic 0) on the ST16C552A part when the Version 1.0.0 interrupt latch mode is selected. The 552/552A is fabricated in an December 1996 Material advanced CMOS process with power down mode to reduce the power 39.81 KB Declaration consumption. The 552A does not support the power down mode.
