GAL22LV10C-10LJ

Programmable Logic Device Pld Overview

The GAL22LV10C-10LJ is a discontinued low-voltage E2CMOS programmable logic device (PLD) manufactured by Lattice Semiconductor. It features a 3.3V architecture with 5V-tolerant inputs, allowing interface with standard 5V TTL devices. The device provides ten output logic macrocells (OLMCs) and supports reconfigurable logic via electrically erasable floating gate technology. Key electrical parameters include a maximum propagation delay of 10 ns, a typical operating supply current of 75 mA at 3.3V, and an operating temperature range of 0°C to +75°C. It utilizes a 28-pin PLCC package.

Programmable Logic Device Pld Feature Summary

• Low Voltage E2CMOS Technology: Operates at 3.3V with high-speed electrical erasure (<100ms) and 20-year data retention.
• 5V Compatible Inputs: Input buffers are compatible with 5V signal levels while maintaining a 3.3V I/O interface standard.
• Flexible OLMCs: Ten Output Logic Macrocells support registered and combinatorial modes with individually programmable polarity.
• Electronic Signature: Includes 64 bits of user-reprogrammable memory for identification or revision control.

Programmable Logic Device Pld Applications

• Glue logic for 3.3V systems interfacing with 5V components
• DMA control circuits
• State machine control
• High-speed graphics processing

Programmable Logic Device Pld Procurement Notes

This component is officially discontinued per PCN#09-10. Verification of availability requires checking secondary market distributors or authorized liquidation partners such as Rochester Electronics. Ensure that the specific ordering suffix 'LJ' corresponds to the conventional leaded PLCC-28 package, as 'LJN' denotes the lead-free variant.

Programmable Logic Device Pld Selection Notes

Select this part only if legacy compatibility with standard 22V10 fuse maps is required alongside 3.3V operation. The GAL22LV10C variant specifically supports 5V input tolerance, whereas the GAL22LV10D variant includes active pull-ups on all pins but lacks the explicit 5V input compatibility description in the same manner. Verify that the 10 ns speed grade meets the system timing requirements.

Programmable Logic Device Pld Part Context

The GAL22LV10 belongs to the GAL22LV10 family of Simple Programmable Logic Devices (SPLDs). It is functionally and parametrically compatible with bipolar and UVCMOS 22V10 devices. The 'C' designation indicates commercial grade performance, and the '10' specifies the 10 ns speed grade. The 'LJ' suffix identifies the 28-pin Plastic Leadless Chip Carrier (PLCC) package.

Programmable Logic Device Pld Replacement Considerations

No direct public substitute part numbers are listed in the provided documentation. As the entire GAL22LV10 product line is discontinued, designers must evaluate modern SPLD or CPLD alternatives from Lattice or other vendors that match the pinout and logic density requirements.
