·其载波频率精确度在商业温度范围内为±150ppm，在工业温度范围内则可达±250ppm，它的精确度比传统的（saw）发射器高出两倍，且无需使用外部晶体振荡器。单片机解密，msc12提供了双数据指针(dptr)加速数据块的移动速度，它能根据外部存储器的速度调节读写速度，在2～9个指令周期之间变化；它还提供给外部存储器16位地址总线(p0和p。低位地址通过p0口复用得到，硬件可以控制p0和p2口是作为地址线还是作为通用的i/o。itisalsopincompatiblewithmicrochip’shcs2codehoppingencoderallowingeasyupgradingtoamoresecureremotekeylessentry(rke)system.the8-pinhcs1operatesoverawidevoltagerangeof5vto13vandhasthreebuttoninputsallowingthesystemdesignerthefreedomtoutilizeupto7functions.theonlycomponentsrequiredfordeviceoperationarethebuttonsandrfcircuitry,allowingaverylowsystemcost.

因指令复杂，故采微指令码控制单元的设计，而risc的指令90%是由硬体直接完成，只有%的指令是由软体以组合的方式完成，因此指令执行时间上risc较短，但risc所须rom空间相对的比较大，至于ram使用大小应该与程序的应用比较有关系。中断可能会在二条指令执行时发生。在这种情况下，允许二条指令和附加的停止周期在isr前执行。这样，与二条指令关联的停止周期会正常执行。但是，停止周期实际上会被嵌入到异常过程时序内。如果一个正常的双周期指令被中断，异常过程将会继续。
