DRM138, Flow Meter Reference Design based on MC9S08GW64

DRM138, flow meter reference design based on MC9S08GW64 is a low-cost, low-power system. This reference design is specifically targeted for gas and fluid meters. This design fulfils the basic market requirement for the Flow meter: low-power, low-cost, able to run on battery and with automated meter reading (AMR). The main attraction of this design is that the flow sensing module of the MCU keeps running even when the MCU goes into low-power mode. Since the MCU is in low-power mode for most of the time, it reduces the power consumption
