GAL22LV10C-10LJN

Programmable Logic Device Pld Overview

The GAL22LV10C-10LJN is a Simple Programmable Logic Device (SPLD) from the Lattice GAL®22V10 family, manufactured by Lattice Semiconductor Corporation. It features an E2CMOS technology with 10 macrocells and supports up to 22 input/output pins. The device operates at a maximum propagation delay of 10 ns and a maximum frequency of 125 MHz. It functions within a supply voltage range of 4.75 V to 5.25 V and consumes a typical operating current of 80 mA. The component is housed in a 28-pin PLCC package and is rated for industrial temperature ranges.

Programmable Logic Device Pld Feature Summary

• E2CMOS Technology: Non-volatile programmable logic offering high performance with low power consumption.
• High Speed: Maximum propagation delay of 10 ns and maximum operating frequency of 125 MHz.
• I/O Configuration: Supports up to 22 I/Os with 10 registered macrocells for complex logic implementation.
• Industrial Temperature Range: Designed for operation between -40°C and +85°C.

Programmable Logic Device Pld Applications

• Digital logic replacement for discrete TTL/CMOS circuits
• Address decoding and memory interface control
• State machine implementation in embedded systems
• Signal buffering and protocol conversion

Programmable Logic Device Pld Procurement Notes

Verify RoHS compliance status as older revisions may not meet current environmental standards. Confirm package integrity upon receipt, as PLCC packages are susceptible to pin bending during handling. Check for obsolescence notices or PCNs regarding manufacturing changes. Ensure programming equipment supports the specific voltage requirements for E2CMOS devices.

Programmable Logic Device Pld Selection Notes

Select this model when a 10-macrocell SPLD with 10 ns speed is required. Compare against GAL22V10 variants if higher voltage tolerance or different packaging is needed. Consider GAL16V8 variants for simpler logic needs with fewer I/Os. Verify that the 5V supply rail matches the system design constraints.

Programmable Logic Device Pld Part Context

This part belongs to the GAL22V10 series, a legacy line of Generic Array Logic devices. It serves as a drop-in replacement for older PAL/GAL components in existing designs. The 'C' suffix typically denotes commercial/industrial temperature grading, while 'LJN' indicates the PLCC package and tube packaging format.

Programmable Logic Device Pld Replacement Considerations

Direct pin-compatible replacements include other GAL22V10 variants with matching speed grades (e.g., GAL22V10C-10LP). Cross-reference with ispGAL22V10 for enhanced features, though pinouts may differ. Verify electrical characteristics match exactly before substituting in critical timing paths.
