Description and Introduction

3.3V In-System Programmable SuperFAST? High Density PLD The ISPLSI2128VE-250LT100 is a high-density programmable logic device (PLD) manufactured by Lattice Semiconductor (LALTCE). Below are the key specifications, descriptions, and features:

### **Specifications:**
- **Device Type:** In-System Programmable Large Scale Integration (ISPLSI) 2128VE  
- **Speed Grade:** -250 (250 MHz performance)  
- **Package:** LT100 (100-pin Thin Quad Flat Pack, TQFP)  
- **Operating Voltage:** 3.3V  
- **Density:** 128 macrocells  
- **Number of I/Os:** 64  
- **Maximum Frequency:** 250 MHz  
- **Propagation Delay:** 5 ns (typical)  
- **Programmable Logic Blocks (PLBs):** 8  
- **Global Routing Pool (GRP):** Yes  
- **JTAG Boundary Scan:** Supported  

### **Descriptions:**
- The ISPLSI2128VE is part of Lattice's high-performance E²CMOS® PLD family.  
- It features in-system programmability (ISP) via IEEE 1149.1 (JTAG) interface.  
- Designed for high-speed logic integration in applications such as telecommunications, networking, and industrial control.  

### **Features:**
- **High-Density PLD:** 128 macrocells for complex logic designs.  
- **In-System Programmability:** Allows reprogramming without removing the device from the circuit board.  
- **5V Tolerant I/Os:** Supports interfacing with 5V logic levels.  
- **Flexible Architecture:** Combines programmable logic blocks with a global routing pool for efficient signal distribution.  
- **Low Power Consumption:** E²CMOS technology ensures low power operation.  
- **Security Fuse:** Protects design intellectual property from unauthorized access.  
- **Wide Operating Temperature Range:** Suitable for industrial environments.  

This device is ideal for applications requiring high-speed logic integration with reconfigurability.

Application Scenarios & Design Considerations

3.3V In-System Programmable SuperFAST? High Density PLD

Alternative Part Number

  • M4A5-128/64-10YNC --: Lattice MACH4 CPLD with 128 macrocells in the same 100-pin TQFP package, a direct functional replacement for the ispLSI 2128VE family with comparable logic density and 5V-tolerant I/O.
  • EPM7128SLC84-10 --: Altera MAX7000S CPLD with 128 macrocells and 10 ns speed grade, widely available and commonly used as a drop-in substitute for ispLSI2128 designs when pinout is adapted.
  • XC95144XL-10TQ100C --: Xilinx XC9500XL CPLD with 144 macrocells in a 100-pin TQFP, offering similar density and 3.3V operation as a practical alternative for the ispLSI2128VE.
  • LC4256V-75TN100C --: Lattice ispMACH 4256V CPLD in the same 100-pin TQFP package with comparable 256-macrocell density and 3.3V operation; a direct functional replacement for the ispLSI 2128VE family.
  • EPM3256AQC208-7N --: Altera MAX 3000A CPLD with 256 macrocells and 3.3V core, offering similar logic capacity and speed grade as the ispLSI2128VE, suitable as a cross-vendor substitute with pinout adaptation.
  • XC9536XL-10VQG44C --: Xilinx XC9500XL CPLD family provides 3.3V in-system programmable logic with fast pin-to-pin delays; a viable lower-density alternative when full 128-macrocell capacity is not required.
