Description and Introduction

FLASH IN-SYSTEM PROGRAMMABLE (ISP) PERIPHERALS FOR 16-BIT MCUS (3.3V SUPPLY) The **PSD4235G2V-90U** is a highly integrated programmable system device (PSD) designed to enhance microcontroller-based applications by providing flexible memory and peripheral solutions. Combining flash memory, SRAM, and configurable I/O ports, this component simplifies system design while optimizing performance and power efficiency.  

With a **90ns access time**, the PSD4235G2V-90U ensures rapid data retrieval, making it suitable for real-time processing and embedded systems. Its **dual-bank flash memory** architecture allows for efficient firmware updates without interrupting operations, while the integrated SRAM supports dynamic data storage. The device also features **programmable logic**, enabling customization of I/O functions to meet specific application requirements.  

Engineers favor the PSD4235G2V-90U for its **low-power operation**, which extends battery life in portable devices. Its **3.3V operation** aligns with modern low-voltage designs, reducing overall system power consumption. Additionally, the component supports **in-system programming (ISP)**, facilitating easy field upgrades.  

Ideal for industrial control, automotive electronics, and consumer applications, the PSD4235G2V-90U delivers a compact, high-performance solution for complex embedded systems. Its integration of memory, logic, and I/O reduces component count, streamlining development and lowering production costs.  

For designers seeking reliability and versatility, the PSD4235G2V-90U represents a robust choice in programmable system devices.

Alternative Part Number

  • EPM7128SLC84-15 --: CPLD in the same 84-pin PLCC package with comparable macrocell count and 15 ns speed, suitable as a functional substitute for the PSD4235 configuration.
  • ATF1508AS-10JU84 --: High-density CPLD with 128 macrocells in an 84-pin PLCC, offering similar logic capacity and 10 ns performance for the PSD4235G2V-90U replacement.
  • XC95144XL-10TQG100 --: 144-macrocell CPLD with 10 ns speed grade, providing comparable programmable logic resources for designs originally using the PSD4235G2V-90U.
  • XC2C256-7TQ144C --: CoolRunner-II CPLD with comparable macrocell count and 144-pin TQFP package; widely available and a common substitute for older ST uPSD devices in legacy designs.
  • EPM3256AQC208-10N --: MAX 3000A CPLD offering similar logic capacity and 3.3V operation; a well-supported alternative when the ST PSD4235 is obsolete.
  • ATF1508AS-10AU100 --: High-density 3.3V CPLD with comparable logic resources and low power, suitable as a functional replacement for the PSD4235G2V-90U in embedded control applications.
  • ST16C554DCQ64 --: Quad UART with FIFO in a 64-pin QFP, functionally similar to the PSD4235 configurable peripheral/UART interface and widely available.
  • TL16C554AIPN --: Quad asynchronous communications element with 16-byte FIFOs, a common drop-in style replacement for UART functions in the PSD4235 family.
  • ATF1508AS-10JU84 --: CPLD with comparable logic density and 5V-tolerant I/O, suitable for replacing the programmable logic portion of the PSD4235 device.
