P80C31X2/32X2：80C51 8位微控制器系列4K/8K/16K/32K ROM/OTP 128B/256B RAM，低压（2.7至5.5 V），低功耗，高速（30/33 MHz）

本数据手册中所述的飞利浦微控制器属高性能静态80C51设计，采用飞利浦?高密度CMOS技术，工作范围从2.7 V至5.5 V。其同时支持6时钟和12时钟操作。

P8xC31X2/51X2和P8xC32X2/52X2/54X2/58X2分别包含128字节RAM 和256字节RAM，32根I/O线，3个16位计数/定时器，一个六源，四优先级嵌套中断结构，一个多处理器通信、I/O扩展或全双工UART的串行I/O端口，以及片内振荡器和时钟电路。

此外，该设备具有低功耗的静态设计，提供低至零的各种工作频率。具有两种可软件配置的降低功耗的模式-空闲模式和掉电模式。空闲模式冻结CPU同时允许RAM、定时器、串口和中断系统继续工作。掉电模式保存RAM内容但冻结振荡器，从而使所有其它芯片功能失效。设计是静态的，因此可以停止时钟而不丢失用户数据。随后可以从时钟停止的时间点恢复执行。
