Maxim Integrated MAX14824 IO-Link® Master Transceiver is an IO-Link master interface that integrates an IO-Link physical layer transceiver with an auxiliary digital input and two linear regulators. High port count IO-Link master applications are supported through in-band SPI addressing. The 12MHz SPI interface minimizes host controller access times. In-band addressing and selectable SPI addresses enable cascading up to 16 devices. Maxim MAX14824 supports all the IO-Link data rates and features slew-rate-controlled drivers to reduce EMI. The driver is guaranteed to drive up to 300mA (min.) load currents. Internal wake-up circuitry automatically determines the correct wake-up polarity, allowing for the use of simple UARTs for wake-up pulse generation. MAX14824 is available operates over the extended -40ºC to +105ºC temperature range.
MAX14824 evaluation kit (EV kit) consists of a MAX14824 evaluation board and software. The EV kit is a fully assembled and tested circuit board that evaluates MAX14824.
Maxim Integrated MAX14830 Quad Serial UART is the industry's first quad SPI/I2C UART. Each UART of this Maxim device features 128 words of receive and transmit first-in/first-out (FIFO) and a high-speed serial peripheral interface (SPIK) or I2C controller interface. A PLL and fractional baud-rate generators allow a high degree of flexibility in baud-rate programming and reference clock selection. Logic-level translation on the transceiver and controller interfaces allows ease of interfacing to microcontrollers, FPGAs, and transceivers that are powered by differing supply voltages. Extensive features simplify transceiver control in halfduplex communication applications. Maxim MAX14830 features the ability to synchronize the start of an individual UART’s transmission by SPI-based triggering. On-board timers allow programming of delays between transmitters as well as clock generation on GPIOs. The 128-word FIFOs have advanced FIFO control, reducing host processor data flow management. MAX14830 is specified to operate over the extended -40ºC to +85ºC temperature range.
MAX14830 evaluation kit (EV kit) provides a proven design to evaluate the MAX14830. The EV kit operates from a +3.3V and a +24V DC supply and requires 100mA of current from each supply. This EV kit requires a user-supplied SPI/I2C controller and software. The EV kit comes with a MAX14830ETM+ installed.
