PALCE16V8Q25JC4

The Advanced Micro Devices PALCE16V8Q25JC4 is an advanced programmable logic device (PLD) from the PALCE16V8 family. Built with low-power, high-speed, electrically erasable CMOS technology, it is functionally compatible with all 20-pin GAL devices and can directly replace PAL16R8 devices. This device utilizes a sum-of-products (AND/OR) architecture, allowing for easy implementation of complex logic functions. The fixed OR array supports up to eight data product terms per output, with each macrocell programmable as registered or combinatorial with active-high or active-low output.

Key features include a 5-ns propagation delay for the "-5" version and 7.5-ns for the "-7" version. The PALCE16V8Z variant offers zero standby power, making it suitable for battery-powered applications. The device is programmed through floating-gate cells in the AND logic array, which can be electrically erased. It comes in a 20-pin package and is RoHS3 compliant.

This PLD is designed for applications requiring flexible logic implementation. Its universal architecture and compatibility with standard PAL devices make it a versatile choice for designers. The ability to configure macrocells as registered or combinatorial outputs provides significant design flexibility.
