CLB Synthesizer

The PIC16F13145 family of microcontrollers introduce a new peripheral, the Configurable Logic Block (CLB).

The CLB peripheral, comprised of 32 Basic Logic Elements (BLE), allows the users to incorporate hardware-based custom logic into their applications. Each logic element’s Look-up Table (LUT) based design offers vast customization options, and the CPU-independent operation improves the response time and power consumption.

The user must configure elements as matrix multiplexers, LUTs, and flip-flops to achieve a given logic function, which is similar to the Configurable Logic Cell (CLC) on PIC® MCUs or the Configurable Custom Logic (CCL) on the AVR® MCUs. However, the matrix is much larger and is interconnected to a higher degree - which enables users to make more complex logic functions. To help users focus on the intended functionality of their logic design without having to understand the inner workings of the peripheral, Microchip provides a GUI (CLB Synthesizer) used for Configurable Logic Block configuration.
