Once configured, the MAX22516 data link controller operates the IO-Link transceiver and requires no intervention from the external microcontroller during normal operation. Alternatively, the IO-Link transceiver can be controlled using the UART interface (TXEN, TX, and RX) directly, or through the serial-peripheral interface (SPI). The data link controller supports and includes, receive and transmit buffers for IO-link communication. Buffers for maximum size process data, ISDU, event, and page data reduce the need for timecritical microcontroller intervention, which allows the microcontroller to focus on the application layer task.
The MAX22516 features extensive integrated protection to ensure robust communication in harsh industrial environments. All IO-Link interface pins (V24, C/Q, DO, DI, and GND), are reverse voltage protected, shortcircuit protected, and feature integrated ±1kV/500Ω surge protection.
The MAX22516 is available in a tiny WLP package (3.53mm x 3.16mm) or 40-pin TQFN-EP package (5mm x 5mm) and operates over the -40°C to +125°C temperature range.
