    Does PSoC4 work on CMOS Level or on TTL Level?


      Hello Everyone


      I am building a GSM Module by using SIM900B Chip, the UART of which works at CMOS level. My question is: Can I connect that UART directly to the UART of my PSoC4?


      Please Find Attached herewith the Datasheet of SIM900B as reference.
