ST16C580IQ48-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The ST16C580IQ48-F is a dual-channel Universal Asynchronous Receiver/Transmitter (UART) interface integrated circuit 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 16-bit transmit and receive FIFOs for each channel, enhancing throughput efficiency. Packaged in a 48-pin TQFP surface-mount format with dimensions of 9.2mm length and 1.2mm height, it functions reliably across an operating temperature range of -40°C to +85°C.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'F' against the manufacturer's current datasheet to confirm package type and temperature grade alignment. Ensure the 48-TQFP footprint matches the target PCB design. Cross-reference pin assignments with the official ST16C580IQ48-F documentation to prevent interface mismatches during integration.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when dual asynchronous serial ports are required with moderate speed capabilities up to 4 Mbps. The 16-byte FIFO depth balances buffer size and power consumption effectively. Verify that the 2.97V to 5.5V supply range aligns with the system's available voltage rails and that the TQFP-48 package fits the mechanical constraints.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the MaxLinear ST16C series of UART interface controllers. It shares architectural similarities with other devices in the family but is distinct in its dual-channel configuration and 48-pin packaging. It serves as a specialized solution for applications requiring two independent serial links without the complexity of higher-pin-count quad-channel variants.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Direct substitutes include the ST16C550IQ48-F for single-channel requirements or the XR16C854IQ-F for alternative performance profiles. Verify electrical compatibility and pinout correspondence before substitution.
