SI2404-C-FS

Overview

The SI2404-C-FS is a network controller and processor IC categorized as an ISOModem, manufactured by Skyworks Solutions Inc. It operates at a data rate of 2.4 kb/s with a frequency of 4.92 MHz. The device supports SPI, UART, and Parallel interface types and functions within a supply voltage range of 3 V to 3.6 V. Operating current is specified at 17 mA. The component is designed for surface mount installation in a TSSOP-24 package. It supports a minimum operating temperature of -40 C and a maximum of +85 C. Moisture sensitivity is indicated as Yes.

Feature Summary

• Supports V.21, V.22, V.23, V.29, Bell 103, and Bell 212A protocols
• Integrates Data Access Arrangement (DAA) functionality
• Designed for telecom line management applications

Applications

• Telecom line management systems
• Network controller and processor IC implementations
• ISOmodem system-side integration

Procurement Notes

Verify the manufacturer designation carefully, as listings may attribute this part to Silicon Laboratories or Skyworks Solutions due to corporate acquisition history. Confirm the specific suffix FS corresponds to the tube packaging format rather than reel variants. Check RoHS compliance details directly from the datasheet as availability varies. Ensure the source document explicitly identifies the part number to avoid confusion with similar ISOmodem models like the SI2457.

Selection Notes

Select this component when a 2.4 kb/s data rate is required for legacy telecom protocols including Bell and V-series standards. The TSSOP-24 package suits space-constrained surface mount designs. Verify that the 3.3 V supply voltage aligns with the target system architecture. Consider the industrial temperature range if operation outside standard commercial limits is necessary. Confirm interface requirements match the available SPI, UART, and parallel options.

Part Context

This part belongs to the SI2404 series of ISOmodems, which are specialized communication controllers. The series includes evaluation boards such as the SI2404FS10-EVB for development purposes. Related components in the broader portfolio include the SI2457 for higher speed applications. The product falls under the Network Controller & Processor ICs subcategory within Communication & Networking ICs.
