PALCE22V10H-15JC/4

Programmable Logic Device Pld Overview

The PALCE22V10H-15JC/4 is a high-performance Complex Programmable Logic Device (CPLD) from Lattice Semiconductor's PALCE family. It features an advanced E²CMOS process technology, enabling operation at supply voltages of 2.7V to 3.6V. The device provides 10 macrocells and supports up to 22 inputs with a maximum propagation delay of 15ns. Designed for surface-mount applications, it utilizes a 28-pin PLCC package. Key electrical specifications include a maximum operating frequency of approximately 66 MHz and low power consumption characteristics typical of the E²CMOS architecture.

Programmable Logic Device Pld Feature Summary

• State machine implementation in industrial control units
• Memory chip select generation

Programmable Logic Device Pld Procurement Notes

Verify the specific suffix 'JC/4' against the manufacturer's current datasheet to confirm pinout compatibility and electrical tolerances. As a legacy component, availability may be limited; check for end-of-life status or recommended new design alternatives through official Lattice channels before finalizing procurement plans.

Programmable Logic Device Pld Selection Notes

Select this component when non-volatile logic is required without the complexity of full CPLDs. Ensure the design accommodates the 28-pin PLCC footprint. Compare against the GAL22LV10 series if lower voltage operation (2.5V) is needed, noting that the PALCE series offers higher drive strength and speed at standard 3.3V levels.

Programmable Logic Device Pld Part Context

This part belongs to the PALCE (PAL Enhanced CMOS) family, which bridges the gap between traditional PALs and modern CPLDs. Unlike volatile SPLDs, the PALCE series retains programming data indefinitely, simplifying system design by removing the need for configuration memory chips often required with other programmable logic devices.

Programmable Logic Device Pld Replacement Considerations

Direct pin-to-pin replacements are scarce due to proprietary architecture. Consider Lattice's MachXO or CrossLink-N families for modern equivalents, though these require reconfiguration of design files and potentially PCB layout adjustments.
