A seguir é mostrada uma lista bastante completa, numa compilação de mais de 485 Máscaras (códigos secretos) de chips de produtos eletrônicos Motorola® e Freescale®, presentes em equipamentos eletrônicos como centrais de injeção eletrônica.
É bastante comum o fabricante de eletrônicos que solicita junto ao fabricante do chip (no caso a Motorola/Freescale) que identifique o chip de maneira exclusiva, protegendo assim o chip de tentativas de cópia, espionagem industrial, etc.
Para controle interno do fabricante do chip, ele utliza códigos dados como máscaras, que funciona como se fosse um Part Number simplificado, e é escrito junto ao código do cliente. A tabela a seguir traz centenas de máscaras relacionadas com o chip verdadeiro comercial.
