Description and Introduction

High Density Programmable Logic The **ISPLSI3192-70LB272** is a high-performance programmable logic device (PLD) manufactured by **Lattice Semiconductor (LALTCE)**. Below are its key specifications, descriptions, and features based on the available knowledge:

### **Specifications:**
- **Device Type:** In-System Programmable Large Scale Integration (ISPLSI)  
- **Family:** ispLSI 3000 Series  
- **Logic Cells:** 192  
- **Speed Grade:** -70 (70 ns maximum pin-to-pin delay)  
- **Package:** 272-pin Low-Profile Ball Grid Array (LBGA)  
- **Operating Voltage:** 5V  
- **I/O Pins:** 192 (configurable)  
- **Programmable Logic Blocks:** 24  
- **Macrocells:** 96  
- **Maximum Frequency:** ~100 MHz (varies by design)  
- **On-Chip Memory:** None (primarily combinational and sequential logic)  
- **Programmability:** In-system programmable (ISP) via JTAG  

### **Descriptions:**
- The **ISPLSI3192-70LB272** is a member of Lattice’s **ispLSI 3000** family, designed for high-speed, high-density programmable logic applications.  
- It supports **5V operation** and features a flexible architecture with a mix of programmable logic blocks and I/O cells.  
- The device is **in-system programmable (ISP)**, allowing for field upgrades via a standard JTAG interface.  

### **Features:**
- **High-Density PLD:** 192 logic cells with 96 macrocells.  
- **Fast Performance:** 70 ns pin-to-pin delay, suitable for medium-speed designs.  
- **Flexible I/O:** 192 I/O pins with programmable slew rate and pull-up resistors.  
- **JTAG Programming:** Supports boundary scan testing (IEEE 1149.1).  
- **5V Tolerant I/Os:** Compatible with mixed-voltage systems.  
- **Wide Temperature Range:** Commercial (0°C to +70°C) and industrial (-40°C to +85°C) options.  
- **Non-Volatile Configuration:** Retains programming upon power-off.  

This device is commonly used in **digital signal processing, communication systems, and industrial control applications** due to its balance of speed and logic capacity.  

(Note: For exact timing, power consumption, or application-specific details, refer to the official **Lattice Semiconductor datasheet**.)

Application Scenarios & Design Considerations

High Density Programmable Logic

Alternative Part Number

  • LC4256V-75TN176C --: Modern ispMACH 4000V CPLD in a 176-pin TQFP package; offers comparable macrocell count and 75 ns speed grade, and is the recommended migration path for legacy ispLSI 3000 series devices.
  • M4A5-192/96-10VNC --: ispMACH 4A CPLD with 192 macrocells and 96 I/O, functionally similar to the ispLSI3192 architecture and a direct successor family for 5V/3.3V designs.
  • EPM7128SLC84-7 --: Classic MAX 7000S CPLD with 128 macrocells and 7 ns speed; widely available second-source option for legacy 3.3V CPLD sockets, though pinout and logic capacity differ and require redesign.
  • EPM3256AQC208-7 --: Altera MAX 3000A EPM3256A provides 256 macrocells with 7 ns pin-to-pin delay, closely matching the original ispLSI 3192-70 performance and I/O count.
  • XC95288XL-7TQG144C --: Xilinx XC9500XL CPLD family delivers 288 macrocells at 7 ns speed with 3.3V operation, offering a viable cross-vendor alternative for the ispLSI 3192-70.
