4 / 85 page 1 1.0 Introduction Programmable Peripheral PSD3XX Family Field-Programmable Microcontroller Peripheral 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 family architecture (Figure 1) can efficiently interface with, and enhance, almost any 8- or 16-bit 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) • Expanded microcontroller address space (up to 16 times) • An EPROM (with security) and optional SRAM • Compatible with 8031-type architectures that use separate Program and Data Space • Interface to shared external resources. |
