Monolithic RFIC and single-chip MCU is used, thus there is less periphery circuit which ensures
high performance reliability. The chips are overmolded by epoxy resins which are excellent
electrical insulation materials. They protect integrated components from short circuiting, dust,
humidity and other environmental factors that could damage the device.
