Overview
The PC16550DN/NOPB is a single-channel Universal Asynchronous Receiver/Transmitter (UART) manufactured by Texas Instruments. It supports data rates up to 1.5 MBd and features 16-byte transmit and receive FIFOs with counters. The device operates at a typical supply voltage of 5 V, with an operating temperature range from 0°C to +70°C. It is housed in a 40-pin MDIP package designed for through-hole mounting, measuring 52.58 mm in length, 13.97 mm in width, and 4.19 mm in height.
Feature Summary
- Integrated 16-byte transmit and receive FIFO buffers equipped with counters for efficient data handling.
Applications
- Serial communication controller interfaces
Procurement Notes
Verify the specific ordering suffix against official component documentation to confirm pinout compatibility and functional specifications. Ensure that environmental compliance requirements match the intended deployment conditions. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement decisions.
Selection Notes
Select this component when a single UART channel with moderate-speed serial communication capabilities is required. The 1.5 MBd maximum data rate and integrated FIFOs make it suitable for applications needing reliable asynchronous data transfer without complex external buffering logic. Consider the through-hole MDIP package constraints during PCB layout planning.
Part Context
This component belongs to the 16550 family of UART interface controllers, widely used for serial communication tasks. The PC16550 variant specifically offers enhanced performance over standard 16C550 devices with higher baud rate support. It serves as a bridge between parallel processor buses and serial data streams in embedded systems.
