PALCE22V10H-20E4/B3A

Programmable Logic Device Pld Overview

The PALCE22V10H-20E4/B3A is an Electrically Erasable Programmable Logic Device (EE PLD) manufactured by Advanced Micro Devices. It utilizes a PAL-type architecture implemented in CMOS technology, housed in a 24-pin Plastic Dual In-line Package (PDIP). The device features 22 dedicated inputs and 10 I/O lines, organized into 132 product terms with macrocell output logic. Designed for operation at a supply voltage of 5 V, the -20 speed grade specifies a maximum propagation delay of 20 ns, supporting a maximum clock frequency of 50 MHz. It operates within a commercial temperature range of 0 °C to 70 °C.

Programmable Logic Device Pld Feature Summary

• PAL-type EE PLD architecture with 22 inputs and 10 I/Os
• CMOS technology ensuring low power consumption
• 20 ns maximum propagation delay (50 MHz max clock)
• Standard 24-pin PDIP package

Programmable Logic Device Pld Applications

• Address decoding and chip select generation
• Bus protocol translation
• Simple state machine implementation
• Logic replacement for discrete gates

Programmable Logic Device Pld Procurement Notes

Verify the specific suffix 'B3A' against official AMD documentation to confirm if it denotes a unique tape-and-reel packaging variant or a specific quality certification, as standard datasheets often list only the base part number. Confirm RoHS compliance status, as older PALCE series devices may have non-compliant variants. Ensure the supplier provides valid traceability for this legacy component.

Programmable Logic Device Pld Selection Notes

Select the -20 speed grade when system timing requirements demand a maximum propagation delay of 20 ns. Choose the PDIP package for through-hole prototyping or high-reliability manual assembly applications. Verify that the 10 I/O capacity and 132 product terms are sufficient for the target logic complexity before finalizing the design.

Programmable Logic Device Pld Part Context

This component belongs to the PALCE (Programmable Array Logic, Commercial, Erasable) family from AMD. These devices were designed to replace complex discrete logic circuits, offering reprogrammability via UV erasure and electrical programming. The PALCE22V10 specifically targets general-purpose logic applications requiring moderate I/O density and fast switching speeds.

Programmable Logic Device Pld Replacement Considerations

Direct pin-compatible replacements include the Lattice GAL22V10 or Atmel ATF22V10C. When substituting, verify that the new device supports the same 5 V supply voltage and matches the 20 ns timing specifications to ensure signal integrity in existing designs.
