Description and Introduction

In-System Programmable High Density PLD The ISPLSI2032-80LT44 is a High-Density Programmable Logic Device (HDPLD) manufactured by Lattice Semiconductor. Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Device Type:** In-System Programmable Large Scale Integration (ISPLSI)  
- **Family:** 2000V  
- **Part Number:** ISPLSI2032-80LT44  
- **Package:** 44-Lead Thin Quad Flat Pack (TQFP)  
- **Speed Grade:** -80 (80ns pin-to-pin delay)  
- **Operating Voltage:** 5V  
- **Number of Logic Cells:** 32  
- **Number of I/O Pins:** 32  
- **Number of GLBs (Generic Logic Blocks):** 4  
- **Number of ORP (Output Routing Pool) Terms per GLB:** 20  
- **Maximum Frequency:** 125 MHz (estimated)  
- **In-System Programmable (ISP):** Yes (via IEEE 1149.1 JTAG interface)  
- **Operating Temperature Range:** Commercial (0°C to +70°C)  

### **Descriptions:**  
- The ISPLSI2032 is a high-performance, electrically erasable programmable logic device (EEPLD).  
- It features a flexible architecture with a combination of programmable AND/OR arrays and macrocells.  
- Supports in-system programming (ISP) for easy field upgrades.  
- Designed for applications requiring medium-density logic integration.  

### **Features:**  
- **High-Density PLD:** 32 logic cells, 4 GLBs, and 32 I/O pins.  
- **Flexible Routing:** Global Routing Pool (GRP) for efficient signal distribution.  
- **Programmable I/O:** Supports bidirectional I/O with individual tri-state control.  
- **JTAG Boundary Scan:** Compliant with IEEE 1149.1 for testing and programming.  
- **5V Operation:** Compatible with TTL and CMOS interfaces.  
- **Security Fuse:** Prevents unauthorized access to programmed logic.  
- **Wide Applications:** Used in digital systems, communication interfaces, and control logic.  

This device is ideal for designs requiring moderate logic capacity with in-system programmability.

Application Scenarios & Design Considerations

In-System Programmable High Density PLD

Alternative Part Number

  • M4A3-32/32-10VC-12VI --: M4A3 series is Lattice's direct successor to ispLSI 2032 CPLDs, offering 32 macrocells in a 44-pin TQFP package with comparable 10ns speed grade and 3.3V operation.
  • EPM7032LC44-15 --: Altera MAX 7000 EPM7032 is a functionally equivalent 32-macrocell CPLD in a 44-pin PLCC package, widely used as a drop-in replacement for ispLSI2032 designs.
  • XC9536XL-10VQG44C --: Xilinx XC9500XL series CPLD in 44-pin VQFP provides comparable logic density and 3.3V operation, suitable for redesigns replacing the ispLSI2032-80LT44.
  • LC4032V-75TN44C --: ispMACH 4000V family provides a pin-compatible 32-macrocell CPLD in 44-pin TQFP with 7.5ns speed, suitable as a functional replacement for the older ispLSI 2032 device.
