As life quality continues to improve, increased attention is being given to personal safety and the prevention of accidents in both homes and commercial premises. Safety related products are usually regulated by national policies due to their inherent life protection and property protection qualities. The security product development industry shows remarkable stability when compared with other industries and continues to exhibit good market potential and beneficial development value.
Holtek Semiconductor has been deeply involved in the security and safety product field for many years, during which time it has developed a wide range of special MCUs for fire protection, security and environmental detection. These MCU devices are seeing widespread use in smoke detectors, CO/GAS detectors, smoke and CO composite detectors and other products. One of the main features in the Holtek fire protection and security MCUs is their functionally integrated AFE analog circuit which offers a higher level of internal characteristic consistency. This greatly reduces the number of required external components with a resulting large reduction in product development time.
