Description

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.

Implementing your design has never been easier than with PSDsoft-WSI's software development suite. Using PSDsoft, you can do the following:
• Configure your PSD211R to work with virtually any 8-bit microcontroller
• Specify what you want implemented in the programmable logic using a high-level Hardware Description
   Language (HDL)
• Simulate your design
• Download your design to the part using a programmer.

Throughout this data sheet, references are made to the PSD211R. In most cases, these references also cover the ZPSD211R and ZPSD211RV products. Exceptions will be noted. Also, references to the ZPSD211R will also cover the low-voltage ZPSD211RV. (Again, exceptions will be noted.) Use the following table to determine what references cover which product versions:
