5.8GHz All-in-One SoC Including RF Transceiver, DSRC Modem & MCU

概要

The FC3860A is a single-chip SoC for electronic toll collection, in which 5.8GHz RF, a Dedicated Short-range Communication (DSRC) modem, and MCU are integrated. The chips provide performance and functions which conform to the Korean DSRC standard, TTAS.KO-06.0025/R1.

Various peripherals like smart card interface, USB, DAC, ADC, LCD interface, keypad scanner, UART, SPI, IIC, IIS, etc. are integrated.

A software development kit (SDK) that fully covers all the parts of the SoC is also provided. Users can easily develop their own DSRC applications through the well-defined APIs.

With its high-level of integration, small size, high performance, and ease of use, the FC3860A is the ideal choice for Electronic Toll Collection System (ETCS), Advanced Traveler Information System (ATIS) and other various DSRC applications.
