PALCE16V8H-15JC/4

The Lattice PALCE16V8H-15JC/4 is an advanced 20-pin Programmable Logic Device (PLD) built with low-power, high-speed, electrically erasable CMOS technology. It offers a propagation delay of 5 ns, making it suitable for high-speed applications. This device is functionally compatible with all 20-pin GAL devices and can directly replace PAL16R8 devices, excluding the PAL16C1.

The PALCE16V8 architecture utilizes a sum-of-products (AND/OR) logic structure, allowing users to implement complex logic functions efficiently. The device features eight independently configurable macrocells that can be programmed as registered or combinatorial outputs with active-high or active-low configurations. The programming matrix implements a programmable AND logic array driving a fixed OR logic array. Buffers for device inputs have complementary outputs for user-programmable input signal polarity.

This PLD is pin and function compatible with all 20-pin PAL devices. Its electrically erasable CMOS technology provides reconfigurable logic and full testability. The PALCE16V8Z variant offers zero standby power, drawing a maximum of 30 µA, which is ideal for battery-powered operation. Unused input pins should be tied directly to VCC or GND to ensure proper operation.
