UARTs (Universal Asynchronous Receiver Transmitter) datasheet and documents for ST16C1550IQ48-F
UARTs (Universal Asynchronous Receiver Transmitter) Overview
The ST16C1550IQ48-F is a dual-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 integrated 16-byte transmit and receive FIFOs to enhance throughput efficiency. Packaged in a 48-pin Thin Quad Flat Package (TQFP) with surface mount installation, it measures 9.2mm in length and 1.2mm in height. The component is rated for an operating temperature range from -40°C to +85°C.
UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary
- Dual-channel UART architecture supporting RS-485 and RS-232 communication standards
- Integrated 16-bit transmit and receive FIFO buffers for improved data handling
- Wide supply voltage compatibility ranging from 2.97V to 5.5V
UARTs (Universal Asynchronous Receiver Transmitter) Applications
- Industrial control systems requiring reliable serial communication
- Embedded devices utilizing RS-485 or RS-232 interfaces
- Multi-port serial expansion solutions in compact form factors
UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes
Verify the specific manufacturer designation, as historical records indicate Exar as the original producer before acquisition by MaxLinear. Confirm that the IQ48 suffix corresponds to the industrial temperature grade (-40°C to +85°C) and TQFP package variant. Ensure compatibility with existing board layouts designed for 48-pin QFP footprints.
UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes
Select this component when dual independent UART channels are required in a single package. It is suitable for designs needing support for both RS-485 and RS-232 protocols without external transceivers if integrated drivers are present. Consider the 48-pin TQFP footprint constraints and the 2.97V to 5.5V power supply requirements during schematic design.
UARTs (Universal Asynchronous Receiver Transmitter) Part Context
This part belongs to the ST16C15xx series of UART controllers. It shares architectural similarities with other members like the ST16C2550 but differs in channel count and specific interface capabilities. The series is characterized by high-performance FIFOs and wide voltage operation, serving as a bridge between parallel microprocessor buses and serial communication lines.
UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations
The XR16M2550IL32-F offers similar UART functionality but utilizes a 32-pin QFN package and lower voltage range (1.62V-3.63V), requiring significant PCB redesign. Direct pin-to-pin replacements within the same 48-pin TQFP form factor should be verified against official substitution lists.
