PALCE20V8Q-10PC/5

Overview

The PALCE20V8Q-10PC/5 is a high-performance Complex Programmable Logic Device (CPLD) from the Vantis PALCE family. It features 20 macrocells and supports up to 8 inputs and 8 registered outputs within a 24-pin PLCC package. The device operates at a maximum propagation delay of 10 ns, ensuring fast logic switching speeds suitable for synchronous digital systems. It utilizes advanced CMOS technology for low power consumption while maintaining compatibility with standard TTL and CMOS logic levels.

Feature Summary

• Provides flexible programmable logic architecture with dedicated macrocells for complex state machine implementation
• Supports high-speed synchronous operation with registered outputs for precise timing control
• Features low-power CMOS technology designed for energy-efficient digital applications

Applications

• Address decoding in microprocessor-based systems
• State machine implementation for control logic
• Bus protocol conversion between different logic families

Procurement Notes

Verify the specific suffix 'Q' indicates commercial temperature range and 'PC' denotes the plastic leaded chip carrier package. Confirm the '-10' speed grade matches system timing requirements. Ensure the manufacturer source is authorized to guarantee component authenticity and traceability for critical deployments.

Selection Notes

Select this component when a moderate number of macrocells are required for glue logic or simple state machines. Compare against higher-density CPLDs if more I/O pins or product terms are needed. Consider the 24-pin package size constraints during PCB layout planning to ensure adequate clearance for adjacent components.

Part Context

This part belongs to the PALCE series, which bridges the gap between traditional GAL devices and larger FPGAs. It offers a cost-effective solution for replacing multiple discrete logic gates. The Vantis brand represents the continuation of legacy Lattice Semiconductor CPLD technologies after corporate restructuring.

Replacement Considerations

Direct pin-compatible replacements may include other PALCE20V8 variants with different speed grades or temperature ranges. Verify functional equivalence regarding macrocell configuration and output drive strength before substitution.
