A Atmel fornece todos os componentes necessários para um sistema de acesso veicular, dos receptores de rádio UHF, transmissores, transceptores até receptores de campos magnéticos de 125kHz, estações base e CIs para driver de bobinas. Esses dispositivos altamente integrados requerem mínimos circuitos externos, pois todos os componentes de RF são integrados no receptor. Eles dispõem de um caminho de sinal RF de terminação única para serem facilmente casados a uma antena de quarto de onda (λ/4) ou antena impressa no PCB.

Os componentes para veículos Atmel incluem valiosos recursos para economia de energia. Por exemplo, o recurso configurável para consulta automática com tempo de verificação programável dos receptores Atmel mantém o mínimo consumo de energia. O modo de baixo consumo de energia dos controladores de antena Atmel minimiza o consumo de energia, enquanto a saída programável de energia dos transmissores Atmel controla eficientemente o consumo de energia.
