Description and Introduction

In-System Programmable High Density PLD The **ISPLSI2032-135LT44** is a high-performance programmable logic device (PLD) manufactured by **Lattice Semiconductor**. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Device Type:** In-System Programmable Large-Scale Integration (ISPLSI)  
- **Family:** 2000V Series  
- **Logic Cells:** 32 (32 Registers)  
- **Gates:** 1,000 PLD Gates  
- **Macrocells:** 32  
- **I/O Pins:** 32  
- **Speed Grade:** 135 MHz  
- **Operating Voltage:** 5V  
- **Package:** 44-Lead Thin Plastic Quad Flat Pack (TQFP)  
- **Operating Temperature Range:** Commercial (0°C to +70°C)  

### **Descriptions:**
- **Architecture:** Combines a high-density programmable logic array with flexible routing resources.  
- **In-System Programmability (ISP):** Supports reprogramming via a standard 5V power supply without removing the device from the circuit.  
- **On-Chip Memory:** Includes E²CMOS technology for non-volatile configuration storage.  
- **Applications:** Used in digital logic designs, glue logic, and system-level integration.  

### **Features:**
- **High Performance:** Supports clock speeds up to **135 MHz**.  
- **Flexible I/O:** 32 fully configurable I/O pins with programmable slew rate control.  
- **Global Routing Pool (GRP):** Enables efficient signal distribution across the device.  
- **JTAG Boundary Scan:** Supports IEEE 1149.1-compliant testing.  
- **Security Fuse:** Provides protection against unauthorized access to the configuration.  

This device is ideal for designs requiring moderate logic density with high-speed operation and reprogrammability.

Application Scenarios & Design Considerations

In-System Programmable High Density PLD

Alternative Part Number

  • M4A3-32/32-10VC-12VI --: Pin-compatible ispMACH 4A CPLD in the same 44-pin TQFP package with comparable 32-macrocell density and 10 ns speed grade, a direct functional replacement for the ispLSI 2032.
  • EPM7032LC44-15 --: Classic MAX 7000 CPLD with 32 macrocells in a 44-pin PLCC/TQFP footprint, widely available and electrically similar to the ispLSI 2032 for legacy designs.
  • XC9536XL-10VQG44C --: Low-cost XC9500XL CPLD in a 44-pin VQFP package offering comparable logic capacity and 10 ns performance, suitable as a drop-in logic replacement with minor pin remapping.
  • M4A5-32/32-10VNC --: Lattice's direct in-system programmable logic successor family (MACH4A5) with 32 macrocells and 5V operation, functionally compatible with the ispLSI2032 in most legacy designs.
  • ATF1502AS-10JU44 --: Atmel/Microchip CPLD with 32 macrocells in a 44-pin PLCC package, commonly used as a drop-in replacement for ispLSI2032 devices in existing boards.
  • EPM7032SLC44-10 --: Classic MAX7000S CPLD with 32 macrocells and 44-pin PLCC package, widely available alternative for 5V CPLD designs originally using ispLSI2032.
