GAL22V10D-25LPN

Programmable Logic Device Pld Overview

The GAL22V10D-25LPN is a discontinued Simple Programmable Logic Device (SPLD) from Lattice Semiconductor, utilizing E2CMOS technology. It features 22 input/output pins and 10 output logic macrocells within a 28-pin Plastic Leadless Chip Carrier (PLCC) package. The device operates at a maximum propagation delay of 25 ns with a typical supply current of 75 mA. It supports commercial temperature ranges from 0°C to +75°C and requires a 4.75 V to 5.25 V power supply. The part includes an electronic signature for identification and active pull-ups on all pins.

Programmable Logic Device Pld Feature Summary

• E2CMOS Technology: Electrically erasable floating gate architecture allowing reprogrammability with high-speed electrical erase times under 100 ms.
• Output Logic Macrocells: Ten OLMCs provide flexible configuration for registered or combinatorial I/O modes with individual product-term control.
• Active Pull-Ups: Built-in active pull-up circuits on all pins ensure inputs float to a TTL high level when unconnected.
• Electronic Signature: Includes 64 bits of user-reprogrammable memory for identification codes or revision tracking.

Programmable Logic Device Pld Applications

• DMA Control
• State Machine Control
• High Speed Graphics Processing
• Standard Logic Speed Upgrade

Programmable Logic Device Pld Procurement Notes

This component is officially discontinued per Product Change Notification PCN#09-10. No new manufacturing is available. Verification of authenticity is critical as only legacy inventory or third-party stock may exist. Designers should confirm the specific lead-free PLCC package variant matches their existing footprint requirements before considering any remaining stock.

Programmable Logic Device Pld Selection Notes

Select this part only for maintenance of legacy systems requiring exact GAL22V10 compatibility. The -25 speed grade offers a 25 ns maximum propagation delay. Ensure the design utilizes the 28-pin PLCC form factor. For new designs, consider modern Lattice ispGAL alternatives or FPGAs, as this SPLD family lacks contemporary low-power features and secure boot capabilities found in newer architectures.

Programmable Logic Device Pld Part Context

The GAL22V10 series represents Lattice's high-performance Generic Array Logic devices based on E2CMOS processes. This specific model, GAL22V10D-25LPN, denotes the commercial grade, 25 ns speed, Low Power variant in a lead-free PLCC package. It maintains parametric and fuse-map compatibility with older bipolar and UVCMOS 22V10 devices while offering significantly lower power consumption.

Programmable Logic Device Pld Replacement Considerations

Direct pin-to-pin replacements are not explicitly listed in public documentation due to the discontinuation. Designers typically migrate to Lattice ispGAL22LV10 series for similar functionality with improved performance or modern CPLDs/FPGAs for scalable logic density.
