Description and Introduction

3.3V In-System Programmable SuperFAST? High Density PLD The **ISPLSI2128VE** is a high-density programmable logic device (PLD) manufactured by **Lattice Semiconductor**. Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Family:** ispLSI 2000VE  
- **Logic Cells:** 128  
- **Macrocells:** 64  
- **Gates:** 6,000  
- **Speed Grade:** Up to **125 MHz**  
- **Operating Voltage:** **3.3V** (5V tolerant I/O)  
- **Package Options:**  
  - **44-Pin PLCC (Plastic Leaded Chip Carrier)**  
  - **44-Pin TQFP (Thin Quad Flat Pack)**  
- **I/O Pins:** 32  
- **Programmable Logic Blocks (GLBs):** 8  
- **On-Chip Memory:** 64 registers per GLB  
- **In-System Programmability (ISP):** Yes (via IEEE 1149.1 JTAG)  

### **Descriptions:**  
The **ISPLSI2128VE** is a member of Lattice's **ispLSI 2000VE** family, designed for high-performance, low-power applications. It features **non-volatile E²CMOS technology**, allowing reprogrammability and in-system configuration. The device is optimized for **3.3V operation** while maintaining **5V I/O tolerance**, making it suitable for mixed-voltage systems.  

### **Features:**  
- **High-Speed Performance:** Supports system speeds up to **125 MHz**.  
- **Flexible I/O:** 32 I/O pins with **5V tolerance** for interfacing with legacy systems.  
- **In-System Programmability (ISP):** Reconfigurable via **JTAG interface** without removing from the board.  
- **Low Power Consumption:** Optimized for **3.3V** operation, reducing power usage.  
- **Dedicated Clock Resources:** Includes **global and local clock distribution** for timing control.  
- **Wide Temperature Range:** Industrial-grade operation (**-40°C to +85°C**).  
- **Non-Volatile Configuration:** Retains programming when powered off.  

This device is commonly used in **telecommunications, industrial control, and embedded systems** due to its **reliability, reprogrammability, and mixed-voltage support**.

Application Scenarios & Design Considerations

3.3V In-System Programmable SuperFAST? High Density PLD

Alternative Part Number

  • M4A5-128/64-10YNC --: Lattice's direct in-system programmable CPLD replacement family for the ispLSI 2128VE, offering comparable macrocell count and 3.3V operation with a different naming series.
  • EPM7128AETC100-10 --: Altera MAX 7000AE CPLD with 128 macrocells and 3.3V I/O, a widely used functional alternative to the ispLSI2128VE in similar logic-density applications.
  • XC95144XL-10TQG100C --: Xilinx XC9500XL CPLD with 144 macrocells and 3.3V supply, providing comparable programmable logic capacity as a cross-vendor alternative.
  • LC4256V-75TN100C --: Lattice ispMACH 4000V CPLD with 256 macrocells, a direct functional upgrade path from the ispLSI 2128VE in the same vendor family and toolchain.
  • EPM1270T144C5N --: MAX II CPLD with 1270 logic elements, widely available and commonly used as a drop-in replacement for obsolete ispLSI 2128VE designs.
  • XC2C256-7TQ144C --: CoolRunner-II CPLD with 256 macrocells, low-power alternative suitable for replacing the ispLSI 2128VE in legacy designs.
  • M4A5-128/64-10YC --: Direct pin-compatible CPLD replacement from Lattice's MACH4A5 family, same 128-macrocell density and 5V-tolerant architecture, commonly used as the official migration path for ispLSI 2128VE designs.
  • EPM7128SLC84-10 --: Equivalent 128-macrocell CPLD from the MAX7000S family with similar logic capacity and 84-pin PLCC package, widely available and often used as a functional substitute when ispLSI parts are unavailable.
