Overview
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 with virtually any microcontroller.
