Description and Introduction

In-System Programmable 3.3V SuperWIDE? High Density PLD The **ISPLSI5256VA-100LQ208** is a high-performance in-system programmable logic device (ispLSI) manufactured by **LATTICE Semiconductor**. Below are the key specifications, descriptions, and features:

### **Specifications:**
- **Device Family:** ispLSI 5000V  
- **Logic Capacity:** 256 macrocells  
- **Speed Grade:** -100 (10 ns pin-to-pin delay)  
- **Package:** 208-pin Low-Profile Quad Flat Pack (LQFP)  
- **Operating Voltage:** 3.3V  
- **I/O Pins:** 160  
- **Maximum Frequency:** 100 MHz  
- **Programmable Logic Blocks:** 32  
- **Registers:** 256  
- **On-Chip Memory:** 8K bits  

### **Descriptions:**
- **Architecture:** The device features a high-density programmable logic architecture with a combination of programmable AND/OR arrays and macrocells.  
- **In-System Programmability (ISP):** Supports boundary scan testing (IEEE 1149.1 JTAG) for easy reprogramming without removing the chip from the circuit board.  
- **Applications:** Suitable for high-speed logic integration in telecommunications, networking, and industrial control systems.  

### **Features:**
- **High-Speed Performance:** 10 ns pin-to-pin delay.  
- **3.3V Operation:** Low power consumption with TTL-compatible inputs and outputs.  
- **Flexible I/O:** Supports 5V-tolerant inputs and programmable output slew rate control.  
- **Security:** Built-in security bit prevents unauthorized reading of the programmed configuration.  
- **Global Routing Pool (GRP):** Ensures predictable timing and efficient signal routing.  
- **Dedicated Clock Pins:** Multiple clock inputs for synchronous design optimization.  

This device is ideal for designs requiring high-speed logic integration with reprogrammability.

Application Scenarios & Design Considerations

In-System Programmable 3.3V SuperWIDE? High Density PLD

Alternative Part Number

  • LC5256MV-100F256C --: Same ispMACH 5000 family CPLD with equivalent 256-macrocell density and 100 ns speed grade, offered in a different package; functionally compatible replacement.
  • M4A5-256/128-10YNC --: MACH4A5 CPLD with 256 macrocells and comparable 10 ns speed, a well-known drop-in class alternative for legacy ispLSI 5000 designs.
  • EPM3256AQC208-10N --: Altera MAX 3000A CPLD with 256 macrocells and 10 ns speed in a 208-pin QFP, a common cross-vendor substitute for the ispLSI 5256VA.
