请您帮忙翻译一下
各位大虾:
小的以前的搞软件的,对单片机和电路不太熟,现在公司要我设计一电路,要看些英文文献,小的英语一般,对电子,单片机的专业述语很难把握。
The AT89C51 provides the following standard features:
4k bytes of flash;
128 bytes of RAM;
32 I/O lines;
two 16-bit timer/counters;
a five vector two-level interrupt architecture;
a full duplex serial port;
on-chip oscillator and clock circuitry.
In addition:
The AT89C51 is designed with static logic for operation down to
zero frequency and supports two software selectable power saving modes.
The Idle Mode stops the CPU while allowing the RAM, timer/counters,
serial port and interrupt system to continue functioning.
The Power Down Mode saves the RAM contents but freezes the oscillator
disabling all other chip functions until the next hardware reset.
