Description and Introduction

In-System Programmable High Density PLD The **ISPLSI1032E-90LT** is a high-density programmable logic device (PLD) manufactured by **Lattice Semiconductor**. Below are the key specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Device Type:** In-System Programmable Large Scale Integration (ISPLSI)  
- **Family:** 1000E Series  
- **Technology:** E²CMOS (Electrically Erasable CMOS)  
- **Speed Grade:** -90 (90 ns pin-to-pin delay)  
- **Package:** LT (100-pin Thin Quad Flat Pack, TQFP)  
- **Operating Voltage:** 5V ±10%  
- **Number of Logic Cells:** 32 (32 Registers)  
- **Number of I/O Pins:** 64  
- **Macrocells:** 192  
- **Gates (Equivalent):** 6,000  
- **Maximum Frequency:** 90 MHz  

### **Descriptions:**
- **Architecture:** Combines a programmable AND array with fixed OR gates and output logic macrocells.  
- **In-System Programmability (ISP):** Can be reprogrammed while installed in a system via a standard 5V power supply.  
- **Non-Volatile:** Retains configuration after power-off due to E²CMOS technology.  
- **JTAG Support:** IEEE 1149.1 boundary scan testability.  

### **Features:**
- **High-Density PLD:** Suitable for complex logic designs.  
- **Flexible I/O:** 64 I/O pins with programmable slew rate control.  
- **Global Routing Pool (GRP):** Ensures predictable timing performance.  
- **Security Bit:** Prevents unauthorized reading of programmed logic.  
- **Wide Operating Temperature Range:** Commercial (0°C to 70°C) or Industrial (-40°C to 85°C).  

This device is commonly used in applications such as **telecommunications, industrial control, and embedded systems** where reprogrammability and high logic density are required.  

(Note: For the latest datasheet or additional details, refer to **Lattice Semiconductor’s official documentation**.)

Application Scenarios & Design Considerations

In-System Programmable High Density PLD

Alternative Part Number

  • M4A5-128/64-10YC --: Lattice CPLD in the M4A5 (ispMACH 4A) family with 128 macrocells, a functional upgrade path for the ispLSI 1032E; in-system programmable and widely available.
  • EPM7128SLC84-10 --: Altera MAX 7000S CPLD with 128 macrocells and similar 10 ns speed grade; a common cross-family replacement for 5V ispLSI 1032E designs, though pinout and toolchain differ.
  • XC95144XL-10TQG100C --: Xilinx XC9500XL CPLD with 144 macrocells and 10 ns speed, offering comparable logic capacity and 3.3V operation as an alternative architecture to the ispLSI 1032E.
