Abstract: A smart card may include data storage and transmission circuitry, a plurality of voltage controllers to supply operational power to card circuitry, a plurality of oscillators to supply an internal clock for the card, and power management circuitry. The power management circuitry may be configured to shut down the oscillators and at least one, but not all, voltage controllers during a period after a data transmission is completed.
Abstract translation: 智能卡可以包括数据存储和传输电路，向卡电路提供操作电力的多个电压控制器，用于为该卡提供内部时钟的多个振荡器以及电源管理电路。 功率管理电路可以被配置为在数据传输完成之后的一段时间内关闭振荡器和至少一个但不是全部的电压控制器。
