PAL16R6BCNL

Programmable Logic Device Pld Overview

The PAL16R6BCNL is a high-speed Programmable Logic Device (PLD) manufactured by Vantis, belonging to the PAL16R6B family. It features a PAL-type architecture with 10 inputs and 6 registered outputs, providing 64 product terms for complex logic implementation. The device operates at a maximum clock frequency of 25 MHz with a typical propagation delay of 25 ns. It utilizes a 20-pin Plastic Quad Flat Pack (PQCC) or Leadless Ceramic Chip Carrier (LCCC) package. Key functional features include power-up reset, register preload capabilities, and support for a single external clock input, ensuring reliable synchronous operation in digital systems.

Programmable Logic Device Pld Procurement Notes

Verify the specific suffix 'CNL' against the manufacturer's datasheet to confirm the exact package variant and temperature range. Ensure compatibility with existing PCB footprints for the 20-lead QCCJ package. Confirm RoHS status if required, as older PLD families may have non-compliant variants. Cross-reference pinouts with the official Vantis PAL16R6B specification to avoid wiring errors during integration.

Programmable Logic Device Pld Selection Notes

Select the PAL16R6BCNL when registered outputs are required for timing control in designs needing up to 6 output pins. Compare the 25 MHz speed grade against faster alternatives if system timing margins are tight. Consider the 20-pin package constraints versus higher-density PLDs if more I/O lines are needed later. Verify that the TTL-compatible input levels match the driving logic voltage standards.

Programmable Logic Device Pld Part Context

The PAL16R6B series represents a standard generation of registered PAL devices from Vantis (formerly AMD). These components bridge the gap between simple GALs and complex CPLDs, offering deterministic timing for registered outputs. The PAL16R6BCNL specifically denotes the commercial grade version in the plastic quad flat pack package, widely used in legacy industrial and consumer electronics designs requiring robust synchronous logic.

Programmable Logic Device Pld Replacement Considerations

Direct pin-to-pin replacements include the AMD PAL16R6B-2CNL. Check for equivalent offerings from Microchip Technology, which acquired the PLD portfolio. Verify that substitute devices maintain the same 25 ns speed grade and registered output configuration to ensure timing integrity without redesign.
