求翻译：由于VC33片内没有ROM，掉电后，程序和数据信息都将遗失，因此需要外接存储器，DS1270W是一种非易失性的存储器，用于存储处理数据。是什么意思？

As the VC33 chip no ROM, power-down, programs and data will be lost, so the need for external memory, DS1270W is a non-volatile memory for storing process data.

Because no ROM VC 33 chips, after power-off procedures and data information will be lost, and therefore need for external memory, DS W 1270 is a nonvolatile memory to store data processing.

Because VC33 internal does not have ROM, after falls the electricity, the procedure and the data message will all lose outside, therefore will need to meet the memory, DS1270W will be one kind of non-volatility memory, will use in saving the processing data.

Because the VC33 chip does not have ROM, after loss, and data information will be lost, so you need an external storage, DS1270W is a non-volatile memory to store data.

Because there is no ROM in VC33 chip, after losing the electricity, procedure and data information will be lost, will need to connect the storing device, DS1270W is a kind of non-volatile memory device, are used for storing and dealing with the data.
