PAL20R8BCNL

Programmable Logic Device Pld Overview

The PAL20R8BCNL is a Programmable Array Logic (PAL) device manufactured by Vantis Corporation. It belongs to the OT PLD family with a TTL-compatible architecture. The component features 16 input lines and 8 registered output lines, providing 64 product terms for logic implementation. It operates at a maximum clock frequency of 37 MHz and requires a nominal 5 V power supply. The device is housed in a 20-pin Plastic Quad Flatpack (PQCC) package, specifically identified as QCCJ or LDCC20,.4SQ. It supports surface mount installation and functions within an operating temperature range up to 70 °C.

Programmable Logic Device Pld Procurement Notes

Verify the manufacturer origin, as Vantis assets were acquired by AMD. Confirm the specific suffix 'BCNL' corresponds to the intended package and temperature grade against official datasheets. Check RoHS compliance status, as older PAL devices may not meet current environmental standards. Ensure the supplier provides valid traceability documentation for legacy components.

Programmable Logic Device Pld Selection Notes

Select this part when a registered PAL solution with 16 inputs is required. Compare propagation delays if timing constraints are critical, noting the 37 MHz limit. Consider pin compatibility with existing GAL20V8 footprints if replacing older designs. Verify voltage levels match the 5 V TTL requirement of the system.

Programmable Logic Device Pld Part Context

This component is part of the standard PAL20R8 series, widely used in legacy digital designs. Vantis was a prominent manufacturer of such programmable logic before its acquisition by Advanced Micro Devices (AMD). The BCNL suffix typically denotes the plastic quad flatpack package variant suitable for surface mount technology applications.

Programmable Logic Device Pld Replacement Considerations

Direct pin-compatible replacements include other PAL20R8 variants from different manufacturers. GAL20V8 devices may serve as functional substitutes in many registered logic applications due to architectural similarities. Verify electrical characteristics and timing parameters before substitution.
