ST16C2450IQ48-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The ST16C2450IQ48-F is a single-channel Universal Asynchronous Receiver/Transmitter (UART) manufactured by MaxLinear. It operates within a supply voltage range of 2.97V to 5.5V and supports data rates up to 4 Mbps. The device features a 16-byte transmit FIFO and a 16-byte receive FIFO to enhance throughput efficiency. It is housed in a 48-pin Thin Quad Flat Package (TQFP) with surface mount installation. The component is rated for an operating temperature range from -40°C to +85°C, ensuring reliability in industrial environments.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Supports high-speed asynchronous serial communication with data rates reaching 4 Mbps
• Integrates dual 16-byte FIFO buffers for improved data handling and reduced CPU overhead
• Compatible with standard RS232 and RS485 interface protocols

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial automation control systems requiring robust serial connectivity
• Embedded devices utilizing RS485 multi-drop networks
• Point-to-point serial communication links in embedded controllers

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'IQ48' confirms the TQFP-48 package variant. Confirm the manufacturer designation as MaxLinear or Exar depending on the production era. Ensure the RoHS compliance status matches current regulatory requirements for your assembly process. Check for any specific moisture sensitivity level classifications required for storage and reflow soldering profiles.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a single UART channel with moderate FIFO depth is sufficient. The 4 Mbps rate suits most standard industrial protocols. Consider the 48-pin TQFP footprint for PCB layout constraints. Verify that the 2.97V minimum voltage aligns with the system's power rail stability under load conditions.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the ST16C2xxx series of UART controllers. It shares functional similarities with the ST16C2550 but offers only one channel instead of two. The device is often compared to legacy 16550-compatible UARTs but provides enhanced FIFO capabilities and higher speed support. It serves as a bridge between parallel microprocessor buses and serial communication lines.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The ST16C2550IQ48-F is a related dual-channel variant. For single-channel replacements, verify pin compatibility with other 16550-compatible UARTs in TQFP-48 packages. Cross-reference datasheets for register-level compatibility if migrating from older Exar or National Semiconductor designs.
