Why Use Programmable Logic?
Low-density programmable logic excels in applications that require speed and reliability. Programmable logic devices operate using dedicated hardware for each processing task, ensuring rapid response and fixed execution time. Choosing a programmable logic device with the right features and complexity can accelerate your time to market and improve design performance. Discover which product best fits your design needs below.
Configurable Logic Block (CLB)
Reconfigurable Digital Logic Integrated Into a Microcontroller (MCU)
- Wide voltage range (1.8–5.5V Vdd)
- Integrated analog
- Low power consumption
- Small package size (3 × 3 mm)
- Up to 100 MHz
- 32 Look-Up Tables (LUTs)
Complex Programmable Logic Device (CPLD)
Larger-Scale Configurable Digital Logic
- Instant boot-up time
- Up to 160 Input/Output (I/O) pins
- More available logic (up to 128 macrocells) than CLBs
- Up to 133 MHz
Why Use a CLB?
Capable of operating while the MCU is in sleep mode, the CLB peripheral provides parallel complex processing with very low power consumption and a wide voltage range, making it suitable for battery-powered applications. When paired with the MCU’s robust 8-bit core and integrated analog and digital peripherals, the CLB seamlessly connects with other sensors and easily integrates into larger systems. Its small package size is great for space-constrained applications that require cost-effective, low-power and efficient programmable logic or applications that require a companion MCU. Explore the CLB with the easy-to-use CLB synthesizer, a user-friendly tool that can sketch, optimize, synthesize and output your logic design for experienced and beginner designers alike.
Why Use a CPLD?
The CPLD provides fast and expansive digital logic, offering more I/O pins, a larger size and faster processing speeds than the CLB. Coupled with a near instant boot-up time, CPLDs are great for time-sensitive and safety-critical applications. Capable of processing more than a hundred inputs and outputs at once, CPLDs provide efficient and complex hardware-based processing for sophisticated and large-scale design needs.
