　　这里，我们提供对PSD211R芯片的基本介绍，供客户及解密工程师参考借鉴。
　　The low cost PSD211R family integrates high-performance and user-configurable blocks of EPROM and programmable logic into one part. The PSD211R products also provide a powerful microcontroller interface that eliminates the need for external “glue logic”. The part’s integration, small form factor, low power consumption, and ease of use make it the ideal part for interfacing to virtually any microcontroller.The major functional blocks of the PSD211R include:
　　Two programmable logic arrays
　　256 Kb of EPROM
　　Input latches
　　Programmable I/O ports
　　Programmable security
　　The PSD211R family architecture (Figure 1) can efficiently interface with, and enhance,almost any 8-bit multiplexed microcontroller system. This solution provides microcontrollers the following:
　　Chip-select logic, control logic, and latched address signals that are otherwise implemented discretely
　　Port expansion (reconstructs lost microcontroller I/O)
　　An EPROM (with security)
　　Compatible with 8031-type architectures that use separate Program and Data Space.
　　The PSD211R I/O ports can be used for:
　　Standard I/O ports
　　Programmable chip select outputs
　　Address inputs
　　Demultiplexed address outputs.
