Since its establishment, microchip has paid close attention to the embedded control semiconductor product market. In order to occupy the market, it has concentrated all resources in technology, design, production and sales, and developed two fist products: pic8 bit single chip microcomputer (MCU) and high-quality Serial EEPROM. So far, microchip has launched microcontroller peripherals, analog products, RFID smart cards and KEELOQ security products, which can design more comprehensive and valuable embedded control system solutions to meet the growing needs of users
