PAL20R6A2CNS

Programmable Logic Device Pld Overview

The PAL20R6A2CNS is a high-speed Programmable Logic Device (PLD) from the Vantis PAL family, manufactured by Lattice Semiconductor. It features an Output Term (OT) architecture with 10 dedicated inputs and 2 I/O lines, providing 6 registered outputs. The device operates with a maximum propagation delay of 25 ns and supports clock frequencies up to 40 MHz. Packaged in a 28-pin PLCC (Plastic Leaded Chip Carrier), it utilizes TTL-compatible logic levels and is designed for applications requiring fast combinatorial or registered logic functions within a compact form factor.

Programmable Logic Device Pld Feature Summary

• PAL Architecture: 10 dedicated inputs, 2 I/Os, and 6 registered outputs.
• High Speed: 25 ns typical propagation delay; 40 MHz max clock frequency.
• Package: 28-pin PLCC (PQCC28).
• Logic Type: TTL compatible.

Programmable Logic Device Pld Applications

• Address decoding and bus control logic.
• State machine implementation.
• Data path control and timing generation.
• Interface translation between different logic families.

Programmable Logic Device Pld Procurement Notes

Verify the manufacturer origin, as Vantis products were originally AMD/ATI assets now held by Lattice. Confirm the package type matches the specific suffix requirements for your PCB footprint. Ensure the voltage supply aligns with standard 5V TTL operation unless otherwise specified in the official datasheet.

Programmable Logic Device Pld Selection Notes

Select this component when a small number of registered outputs are needed with minimal input count. The 25 ns speed is suitable for moderate-speed digital systems. Compare against the PAL20R6A series for similar functionality but verify pinout compatibility if substituting.

Programmable Logic Device Pld Part Context

This part belongs to the classic PAL20R6 family, widely used in legacy and industrial systems. The 'Vantis' branding indicates its lineage from Advanced Micro Devices (AMD) programmable logic products, which were later acquired and integrated into Lattice Semiconductor's portfolio.

Programmable Logic Device Pld Replacement Considerations

Direct replacements include other PAL20R6 variants such as PAL20R6ACNLSTD. Verify electrical characteristics and pin compatibility before substitution. Cross-reference with Lattice's current GAL or MachXO series for modern equivalents if new designs are required.
