H16450S: UART with Synchronous CPU Interface

Computer Aided Software Technologies, Inc (dba CAST)

Member

The H16450S is a standard UART providing 100% software compatibility with the popular Texas Instruments 16450 device. It performs serial-to-parallel conversion on data originating from modems or other serial devices, and performs parallel-to-serial conversion on data from a CPU to these devices. Developed for easy reuse in ASIC and FPGA applications, the H16450S is available optimized for several technologies with competitive utilization and performance characteristics.

Key Features

  • Capable of running all existing 16450 software
  • Fully Synchronous design. All inputs and outputs are based on rising edge of clock
  • Adds or deletes standard asynchronous communication bits (start, stop and parity) to or from the serial data
  • Independently controlled transmit, receive, line status and data set interrupts
  • Programmable baud generator divides any input clock by 1 to (2^16 - 1) and generates the 16x clock
  • Modem control functions (CTSn, RTSn, DSRn, DTRn, RIn, and DCDn)
  • Modem control functions (CTSn, RTSn, DSRn, DTRn, RIn, and DCDn)
  • False start bit detection; complete status register
