Description and Introduction

3.3V In-System Programmable SuperFAST? High Density PLD The **ISPLSI2128VE-135LT100** is a high-performance programmable logic device (PLD) manufactured by **Lattice Semiconductor**. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Family:** ispLSI 2000VE  
- **Logic Cells:** 128  
- **Macrocells:** 64  
- **Gates:** 6000  
- **Speed Grade:** -135 (135 MHz maximum operating frequency)  
- **Package:** 100-Lead TQFP (Thin Quad Flat Pack)  
- **Operating Voltage:** 3.3V  
- **I/O Pins:** 64  
- **Propagation Delay:** 7.5 ns (typical)  
- **Operating Temperature Range:** Commercial (0°C to +70°C)  

### **Descriptions:**
- **Architecture:** In-system programmable (ISP) using Lattice’s proprietary technology.  
- **EEPROM-Based:** Non-volatile, reprogrammable logic.  
- **Density:** Mid-range complexity suitable for glue logic, state machines, and small control applications.  

### **Features:**
- **In-System Programmability (ISP):** Allows programming and reprogramming without removing the device from the circuit board.  
- **High-Speed Performance:** Supports clock frequencies up to 135 MHz.  
- **Low Power Consumption:** Optimized for 3.3V operation.  
- **Flexible I/O:** 64 I/O pins with programmable slew rate and pull-up resistors.  
- **On-Chip Clock Divider:** Includes a programmable clock divider for flexible timing control.  
- **Security:** Built-in security bit to prevent unauthorized readback of the design.  
- **JTAG Interface:** Supports boundary scan testing (IEEE 1149.1 compliant).  

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

(Note: For detailed datasheets, refer to **Lattice Semiconductor’s official documentation**.)

Application Scenarios & Design Considerations

3.3V In-System Programmable SuperFAST? High Density PLD

Alternative Part Number

  • LC4256V-75TN100C --: Lattice CPLD in the ispMACH 4000V family with 256 macrocells and 3.3V core, a direct functional upgrade path for the ispLSI 2128VE in a 100-pin TQFP package.
  • EPM3128ATC100-10N --: Altera MAX 3000A CPLD with 128 macrocells and 3.3V operation in a 100-pin TQFP, offering comparable logic density and pin count for the same socket.
  • XC9536XL-10TQ100C --: Xilinx XC9500XL CPLD in a 100-pin TQFP with 3.3V supply and in-system programmability, suitable as a lower-density drop-in style replacement for legacy ispLSI designs.
  • M4A5-128/64-10YNC --: Lattice ispMACH4A CPLD with 128 macrocells in a 100-pin TQFP, functionally comparable to the ispLSI2128VE and supported by the same ispLEVER toolchain.
  • EPM7128SLC84-15 --: Classic MAX7000S CPLD with 128 macrocells, widely available and commonly used as a drop-in functional replacement for ispLSI2128 designs, though pinout differs.
  • XC95144XL-10TQ100C --: Xilinx XC9500XL CPLD with 144 macrocells in a 100-pin TQFP, offering comparable logic density and 3.3V operation as an alternative CPLD family.
