Application Scenarios & Design Considerations

CMOS Asynchronous Communications Element

Alternative Part Number

  • SCC2691AC1A44 --: Single-channel UART in a 44-pin PLCC, functionally similar to the 82C50A and widely available as a replacement for legacy Harris UARTs.
  • ST16C550CJ44 --: Industry-standard 16C550-compatible UART with a 44-pin PLCC footprint, offering equivalent serial communication functionality and easy drop-in substitution.
  • TL16C550CFN --: Well-supported 16C550-class UART with FIFO, suitable as a functional alternative when the 82C50A is unavailable, though package and pinout should be verified.
  • ST82C50A-5 --: Pin-compatible UART/LPT controller with the same 82C50A core and 5 MHz speed grade, widely available as a second source.
  • W82C50A-5 --: Direct functional equivalent of the 82C50A UART with matching 5 MHz timing, commonly used as a drop-in replacement.
  • UM82C50A-5 --: Compatible 82C50A-series UART controller offering the same register set and 5 MHz operation for legacy designs.
