Description and Introduction

In-System Programmable High Density PLD The **ispLSI1032E-70LTN** is a high-performance programmable logic device (PLD) manufactured by **Lattice Semiconductor**.  

### **Key Specifications:**  
- **Family:** ispLSI 1000E  
- **Device Type:** CPLD (Complex Programmable Logic Device)  
- **Logic Cells:** 32  
- **Macrocells:** 64  
- **Gates:** 6000  
- **Speed Grade:** -70 (70 ns pin-to-pin delay)  
- **Package:** **LTN** (44-Lead Thin Plastic Quad Flat Pack, TQFP)  
- **Operating Voltage:** **5V**  
- **I/O Pins:** 32  
- **Maximum Frequency:** ~90 MHz (varies based on design)  
- **Programmability:** In-system programmable (ISP) via IEEE 1149.1 (JTAG)  

### **Features:**  
- **High-Density PLD:** Combines logic, registers, and I/O in a single chip.  
- **In-System Programmability (ISP):** Allows reprogramming without removing from the circuit.  
- **5V Operation:** Compatible with legacy 5V systems.  
- **Flexible I/O:** Supports 32 I/O pins with programmable slew rate control.  
- **JTAG Boundary Scan:** Supports testing and debugging.  
- **Non-Volatile E²CMOS Technology:** Retains configuration when powered off.  
- **Wide Temperature Range:** Commercial (0°C to 70°C) or Industrial (-40°C to 85°C) options.  

### **Applications:**  
- Used in digital logic designs, state machines, and glue logic.  
- Common in industrial control, telecommunications, and embedded systems.  

This device is part of Lattice's **ispLSI 1000E** series, known for reliability and ease of integration in 5V systems.

Application Scenarios & Design Considerations

In-System Programmable High Density PLD

Alternative Part Number

  • M4A5-128/64-10YNC --: Lattice CPLD in the MACH4 series with comparable macrocell count and 10 ns speed grade, suitable as a functional replacement for the ispLSI1032E in many legacy designs.
  • EPM7128SLC84-10N --: Classic MAX 7000S CPLD with 128 macrocells and 10 ns speed, widely used as a drop-in alternative for ispLSI1032E-class devices in 5V legacy systems.
  • XC95144XL-10TQG144C --: Xilinx XC9500XL CPLD with 144 macrocells and 10 ns speed, offering similar logic capacity and 3.3V operation for designs migrating away from the ispLSI1032E.
