PSD301B芯片基本介绍
The low cost PSD3XX family integrates high-performance and user-configurable blocks of EPROM, programmable logic, and optional SRAM into one part. The PSD3XX 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 PSD3XX include:
Two programmable logic arrays
256Kb to 1 Mb of EPROM
Optional 16 Kb SRAM
Input latches
Programmable I/O ports
Page logic
Programmable security.
The PSD3XX I/O ports can be used for:
Standard I/O ports
Programmable chip select outputs
Address inputs
Demultiplexed address outputs
A data bus port for non-multiplexed MCU applications
A data bus “repeater” port that shares and arbitrates the local MCU data bus with
external devices.
