Description and Introduction

PSD3XX/ZPSD3XX FAMILY LOW COST MICROCONTROLLER PERIPHERALS The **PSD313B-90JI** is a highly integrated programmable system device (PSD) designed to streamline microcontroller-based system designs. Combining flash memory, SRAM, and programmable logic in a single chip, it enhances efficiency while reducing board space and component count.  

This component features **90 ns access time**, making it suitable for high-speed applications. Its **dual-bank flash memory** allows simultaneous read and write operations, improving system performance. The integrated **SRAM** ensures fast data storage and retrieval, while the **programmable logic** provides flexible I/O configuration, simplifying interface management.  

The **PSD313B-90JI** supports **5V operation** and is compatible with a wide range of microcontrollers, making it versatile for embedded systems. Its in-system programmability enables easy firmware updates without hardware modifications, reducing development time and costs.  

Common applications include **industrial control systems, automotive electronics, and communication devices**, where reliability and real-time processing are critical. With its robust architecture and advanced features, the **PSD313B-90JI** is a dependable solution for complex embedded designs requiring memory, logic, and I/O integration.  

Engineers benefit from its simplified design approach, reducing development complexity while maintaining high performance in demanding environments.

Application Scenarios & Design Considerations

PSD3XX/ZPSD3XX FAMILY LOW COST MICROCONTROLLER PERIPHERALS

Alternative Part Number

  • EPM7032QC44-15 --: CPLD in the same 44-pin PLCC package with comparable logic density and 5V operation, suitable as a functional substitute for the PSD313B-90JI.
  • ATF1504AS-10JU44 --: 5V CPLD with 44-pin PLCC footprint and similar macrocell count, offering a close functional match for the original PSD device.
  • XC9536XL-10VQG44C --: Low-cost CPLD in a 44-pin package with comparable logic capacity; requires attention to 3.3V versus 5V supply differences but is a viable alternative.
