PAL16R8-4JC

Programmable Logic Device Pld Overview

The PAL16R8-4JC is a Complex Programmable Logic Device (CPLD) manufactured by Vantis Corporation. It belongs to the PALCE16V8 family, featuring an EEPROM-based non-volatile memory architecture. The device provides 16 input lines and 8 registered output lines, with a maximum propagation delay of 4 ns. It operates on a single 5 V power supply and is housed in a 20-pin PLCC package. This component supports high-speed logic applications requiring reprogrammability without the need for UV erasure.

Programmable Logic Device Pld Feature Summary

• EEPROM-based technology for electrical erasure and reprogramming
• 16 inputs and 8 registered outputs
• 4 ns maximum propagation delay
• Single 5 V supply operation

Programmable Logic Device Pld Applications

• High-speed digital logic replacement
• Address decoding circuits
• State machine implementation
• Bus interface control

Programmable Logic Device Pld Procurement Notes

Verify the manufacturer origin as Vantis Corporation or its predecessor entities like AMD/Lattice, as part numbers may vary across generations. Confirm the package type is PLCC-20 and the speed grade is -4 (4 ns). Check for RoHS compliance status, as older EEPROM PLDs may not meet current environmental standards. Ensure the programming tool compatibility matches the specific PALCE16V8 family requirements.

Programmable Logic Device Pld Selection Notes

Select this part when a registered output configuration with 16 inputs is required. The -4 speed grade indicates a 4 ns delay, suitable for moderate to high-frequency applications. Compare against the PAL16R8-10 or PAL16R8-15 if slower speeds are acceptable for cost reduction. Ensure the design utilizes the registered output structure, as combinational variants (PAL16L8) lack flip-flops.

Programmable Logic Device Pld Part Context

This component is part of the PALCE16V8 series, which succeeded the original PAL16R8 devices. Vantis Corporation acquired assets from former manufacturers like AMD and Lattice Semiconductor, leading to multiple branding iterations for identical silicon. The 'JC' suffix typically denotes the PLCC package and commercial temperature range.

Programmable Logic Device Pld Replacement Considerations

Direct pin-compatible replacements include PALCE16V8-4JC from Lattice Semiconductor or AMD. Generic equivalents such as GAL16V8B are not compatible due to different architecture and voltage requirements. Verify that the substitute maintains the EEPROM technology for easy reprogramming.
