S1C17M01
Flow meter controller with AFE
■ DESCRIPTIONS
The S1C17M01 is an ultra low-power MCU equipped with an MR (magneto resistive) sensor controller that allows an MR
sensor array optimized for flow measurement (recommended sensor: KG1205-61 manufactured by KOHDEN Co., Ltd.) to be
connected directly. This IC includes an LCD driver to display the flow count and the readouts on the indicator, and the
synchronous serial interface, UART, and I2C interface for wireless communication with a remote meter reading system. This
IC allows measurement of various environmental conditions such as a temperature and humidity measurement using the R/F
converter, and a supply voltage measurement using the supply voltage detection circuit.
