ST16C1450CQ48-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The ST16C1450CQ48-F is a single-channel universal asynchronous receiver and transmitter (UART) manufactured by MaxLinear, Inc. It operates within a voltage range of 2.97V to 5.5V and supports data rates up to 1.5 Mbps with a 24 MHz clock input. The device features a 1-byte transmit holding register (THR) and a 1-byte receive holding register (RHR) with error tagging capabilities. It utilizes a 48-pin TQFP surface-mount package and functions across an operating temperature range of 0°C to +70°C.

• Includes onboard status registers for error indications and operational monitoring
• Supports internal loopback capability for system diagnostics
• Features software-controllable reset output and power down mode

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Battery operated electronics
• Internet appliances
• Handheld terminals
• Personal digital assistants
• Cellular phones DataPort

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix 'F' against official documentation to confirm package type and temperature grade. Ensure compatibility with host processor interfaces, as this component is not compatible with standard industry 16450 drivers or MS Windows serial port drivers.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this model when footprint compatibility with legacy SSI UARTs is required alongside enhanced modem control signals. Consider the 1-byte FIFO depth for applications where higher throughput buffering is unnecessary. Verify that the 48-pin TQFP package meets board space constraints.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This component belongs to the ST16C1450 series of single-channel UARTs. It serves as a replacement for older SSI designs while offering lower access times and higher operating speeds compared to the original SSI 73M1550/2550 counterparts.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Direct pin-compatible replacements include the ST16C1450CJ28 (PLCC-28) and ST16C1450IQ48 (TQFP-48, industrial temp). Cross-compatibility with standard 16450 devices is explicitly prohibited.
