SMD1102 - Summit Microelectronics

SMD1102 (SMD1102 - SMD1113) 10-Bit Data Acquisition System

Serial Clock (SCL) The SCL input is used to clock data into and out of the device. In the WRITE mode data must remain stable while SCL is HIGH. In the READ mode data is clocked out on the falling edge of SCL. Serial Data (SDA) The SDA pin is a bidirectional pin used to transfer data into and out of the device. Data may change only when SCL is LOW, except du.
