UART Communication and Protocol Support

The ST16C654CQ100-F supports asynchronous serial communication, a widely used protocol for reliable data transmission in embedded systems. This device can handle communication speeds up to 5 Mbps per channel, which is suitable for applications where fast data exchange is required.

The 16 independent UART channels allow for multiple data streams to be processed simultaneously, providing flexibility in systems that require multi-channel communication. This makes it ideal for embedded systems, data acquisition, and industrial control systems that need to handle multiple communication lines concurrently.

Operating Voltage and Power Consumption

The ST16C654CQ100-F can operate with a supply voltage of 3.3V to 5V, which makes it compatible with a wide range of systems operating at standard logic voltage levels. This voltage flexibility allows for easy integration into 3.3V or 5V logic systems, commonly found in microcontroller-based applications, automated systems, and data communication devices.

With its low power consumption and ability to operate in a low-power mode, this chip is designed for efficient performance, making it suitable for battery-powered systems, portable devices, and energy-conscious designs. The device provides low standby current, which is essential in power-sensitive applications where power efficiency is paramount.

Data Rate and Baud Rate Support

One of the standout features of the ST16C654CQ100-F is its ability to support a maximum data rate of 5 Mbps per channel. This high data rate ensures fast and reliable communication, making the device suitable for high-performance applications in telecommunication systems, networking equipment, and data logging.

The baud rate is fully configurable from 50 bps to 5 Mbps, allowing the device to be used in a wide range of communication applications. Whether used for low-speed control signals or high-speed data transfer, the ST16C654CQ100-F can be configured to meet specific system requirements.

FIFO Buffer and Flow Control

Each of the 16 UART channels in the ST16C654CQ100-F is equipped with a 128-byte FIFO (First In, First Out) buffer, which helps to reduce the burden on the host processor by allowing the device to temporarily store data before transmitting or after receiving it. This helps to smooth out data transmission, preventing data loss or overflow during high-speed communication.

The device supports both hardware flow control (RTS/CTS) and software flow control (XON/XOFF), allowing for better control of data flow and preventing data overruns during high-speed or burst data transfers.

Interrupts and Programmability

The ST16C654CQ100-F features a fully programmable interrupt system, which allows the device to notify the host processor of certain events such as data ready for transmission or receipt. This interrupt-driven mechanism helps to reduce processor load, as the system can be configured to handle data transfers only when necessary.

The device’s interrupt capabilities support both RX and TX interrupts, enabling efficient management of data streams and reducing the need for continuous polling from the host processor.

Package Type and Integration

The ST16C654CQ100-F is packaged in a 100-pin QFN (Quad Flat No-lead) package, which is ideal for space-constrained applications. The QFN package is known for its compact size and low profile, making it suitable for use in dense PCB designs where real estate is at a premium.

Inside the device, multiple features are integrated, including the line driver, receiver, baud rate generator, and interrupt controller. This level of integration helps reduce component count and simplifies the overall design of the system, resulting in a more efficient and cost-effective solution.

Temperature Range and Reliability

The ST16C654CQ100-F is rated for an operating temperature range of -40°C to +85°C, making it suitable for use in a variety of industrial, automotive, and commercial environments. This broad temperature range ensures that the device can withstand harsh conditions, such as those found in industrial control systems, automotive electronics, and telecom infrastructure, where stable performance is crucial.
