Additional Details

The PEEL18CV8T-7 typically operates on a 5V power supply. It features a programmable AND array and a fixed OR array. Each output macrocell can be configured as either a combinational output, a registered output, or an input. The device is programmed using a standard PEEL programmer. Its electrically erasable nature allows for in-system reprogramming. This feature is particularly beneficial in prototyping and debugging new designs where frequent logic changes are required.

This PEEL device provides a versatile solution for a wide range of digital logic applications, offering a balance of flexibility, performance, and cost-effectiveness. Its reprogrammability allows for design iterations without the need for physical hardware changes, saving time and resources during development. The fast propagation delay ensures high-speed operation, making it suitable for performance-critical applications.
