Field programmable gate array. The **XC4006E4PQ160C** is a Field-Programmable Gate Array (FPGA) manufactured by **Xilinx**. Below are its specifications, descriptions, and features based on factual information:
### **Specifications:**
- **Manufacturer:** Xilinx
- **Family:** XC4000E
- **Part Number:** XC4006E-4PQ160C
- **Logic Cells:** ~6,000 gates (configurable logic blocks)
- **Speed Grade:** -4 (medium speed performance)
- **Package:** PQ160 (Plastic Quad Flat Pack, 160 pins)
- **Operating Voltage:** 5V
- **Operating Temperature:** Commercial (0°C to +70°C)
- **Configuration:** SRAM-based (volatile, requires external configuration memory)
- **I/O Pins:** ~140 user I/Os (varies based on configuration)
- **On-Chip RAM:** Distributed RAM (configurable as memory blocks)
- **Clock Management:** Basic clock distribution (no built-in PLLs/DLLs)
### **Descriptions:**
- The **XC4006E** is part of Xilinx's **XC4000E** series, an older generation FPGA optimized for general-purpose logic integration.
- It features a **5V core voltage** and is designed for applications requiring moderate logic density.
- The **PQ160 package** provides a balance between pin count and physical footprint.
- The device is **SRAM-based**, meaning it must be reconfigured at power-up via an external PROM or microcontroller.
### **Features:**
- **Flexible Logic Structure:** Configurable Logic Blocks (CLBs) for implementing combinational and sequential logic.
- **Programmable Interconnect:** Hierarchical routing resources for signal distribution.
- **I/O Flexibility:** Supports TTL and CMOS standards (5V tolerant).
- **On-Chip Memory:** Can be configured as small RAMs or lookup tables (LUTs).
- **Design Tools Compatibility:** Supported by Xilinx’s legacy tools (e.g., XACTstep, Foundation Series).
This FPGA is typically used in legacy systems, industrial control, and prototyping applications. For modern designs, Xilinx recommends migrating to newer families (e.g., Spartan, Artix, or Kintex).
(Note: The XC4000E series is now obsolete, and replacement parts may be necessary for new designs.)
