NXP Semiconductors Document Number: CM3120 Rev. 1.0, 7/2016 Advance Information IO-link master transceiver CM3120 The CM3120 is an IO-Link master physical layer dedicated to the industrial market. It includes two fully-featured IO-Link channels, which can work in three different operation modes. This circuit integrates an IO-Link frame handler fully compliant with the IO-Link v1.1 specification, and which implements most of the IO-Link communication tasks. The frame handler significantly decreases load of IO-LINK TRANSCEIVER the master microcontroller. The CM3120 also provides several protection and monitoring mechanisms such as overcurrent, overvoltage, and overtemperature. Features Two IO-Link channels with three different operation modes (SIO, UART, and frame handler) Protection mechanisms (overcurrent, overtemperature, overvoltage) EP SUFFIX Configurable through a SPI interface 48 QFN Operating voltage range from 8.0 V to 32 V Suitable for 2/4/8/16 port-applications Can operate as a Master or Device Applications Two integrated LED drivers Factory automation Integrated hardware frame handler (supports all IO-link v1.1 frames and Fieldbus gateways COM1, COM2, and COM3 baud rates) Programmable logic controllers Integrated NMOS gate drivers to control current to the C/Q and L+ lines Process controllers 3V3 3V3 CM3120 24 V Monitoring, LED drivers, Temperature and Overvoltage Protection Gate Drivers SPI Logic Core, MCU Frame handler UART 1 IO-Link 1 Logic & Driver UART 2 IO-Link 2 Logic & Driver Figure 1.
