PALLV22V10-10JC

Overview

The PALLV22V10-10JC is a PAL-type Programmable Logic Device (PLD) IC manufactured by Lattice Semiconductor Corporation. It features 10 macrocells and is housed in a 28-pin PLCC package measuring 11.51x11.51 mm. The device operates with a maximum propagation delay of 10 ns and supports a maximum operating frequency of 100 MHz. It utilizes low-voltage, high-speed, electrically erasable CMOS technology.

Feature Summary

• Built with advanced low-voltage, high-speed electrically erasable CMOS technology for efficient power consumption and rapid signal processing.
• Contains 10 macrocells designed to implement complex combinational or sequential logic functions within a single integrated circuit.
• Utilizes a standard 28-pin Plastic Leaded Chip Carrier (PLCC) package suitable for surface mount applications.

Applications

• Embedded digital logic implementation
• General-purpose programmable logic replacement
• Address decoding circuits

Procurement Notes

Verify the specific suffix 'JC' corresponds to the 28-PLCC package and 10 ns speed grade when sourcing replacements. Confirm that the component is an electrically erasable device requiring appropriate programming equipment. Check current availability status as older GAL/PAL families may have limited supply chains or obsolescence notifications from the manufacturer.

Selection Notes

Select this component for designs requiring a small number of logic outputs with electrical erasability. Ensure the system voltage matches the device specifications. Consider the 28-PLCC footprint constraints during PCB layout. Verify that the 10 macrocell capacity meets the logic density requirements of the target application before finalizing the part selection.

Part Context

This device belongs to the Lattice GAL22LV10 family of simple programmable logic devices. It represents an evolution of traditional PAL architectures using EEPROM technology, allowing for reprogramming without UV exposure. It serves as a drop-in replacement for many older OTP GAL devices in legacy systems.
