GAL22V10D-10LP

Programmable Logic Device Pld Overview

The GAL22V10D-10LP is a discontinued Simple Programmable Logic Device (SPLD) from Lattice Semiconductor, utilizing E2CMOS technology. It features 10 macrocells and operates within a supply voltage range of 4.75 V to 5.25 V. The device specifies a maximum propagation delay of 10 ns and a typical operating current of 90 mA at 5 V. Designed for commercial applications, it functions reliably between 0°C and +75°C. The component is housed in a 24-pin Plastic Dual In-Line Package (PDIP).

Programmable Logic Device Pld Feature Summary

• E2CMOS Technology: Electrically erasable floating gate architecture with high-speed erase times under 100 ms.
• Flexible Macrocells: Ten Output Logic Macrocells (OLMCs) support registered or combinatorial I/O modes.
• Active Pull-ups: Built-in active pull-up circuits on all pins ensure defined logic states for unused inputs.
• Power Efficiency: Offers significant power reduction compared to bipolar devices, with typical currents ranging from 45 mA to 130 mA depending on speed grade.

Programmable Logic Device Pld Applications

• DMA Control Systems
• State Machine Control Logic
• High Speed Graphics Processing
• Standard Logic Speed Upgrades

Programmable Logic Device Pld Procurement Notes

This component has been officially discontinued by Lattice Semiconductor per Product Change Notification PCN#13-10. Availability is restricted to existing inventory or secondary market sources. Verification of the specific ordering suffix 'LP' confirms the PDIP package and commercial temperature rating. Buyers should confirm the authenticity and condition of any available stock due to the end-of-life status.

Programmable Logic Device Pld Selection Notes

Select this part only if legacy compatibility with standard 22V10 fuse maps is required. The -10 speed grade provides a 10 ns maximum delay suitable for moderate frequency applications up to 83.3 MHz. Ensure the design accommodates the commercial temperature range (0°C to +75°C) and the 5V logic levels. Consider modern CPLDs for new designs given the discontinuation.

Programmable Logic Device Pld Part Context

The GAL22V10D series represents Lattice's high-performance Generic Array Logic devices. The 'D' suffix indicates the use of E2CMOS technology, allowing for reprogrammability. This specific model belongs to the low-power variant family, balancing performance with reduced current consumption compared to standard bipolar equivalents.

Programmable Logic Device Pld Replacement Considerations

No direct pin-compatible replacements are documented in the provided source material. Designers may need to evaluate modern Lattice CPLDs such as the MachXO or CrossLink-N families, though these require schematic redesign and different packaging.

Programmable Logic Device Pld FAQ

What is the maximum operating frequency for the GAL22V10D-10LP?

The maximum clock frequency without feedback is 125 MHz. With internal feedback, it is 83.3 MHz, and with external feedback, it is 83.3 MHz.

How does the device handle unused inputs?

The GAL22V10D features active pull-ups on all pins, which pull floating inputs to a TTL high (logic 1). However, connecting unused inputs to Vcc or ground is recommended to improve noise immunity.

What is the function of the Electronic Signature feature?

The device includes 64 bits of reprogrammable memory for an electronic signature, allowing users to store user ID codes, revision numbers, or inventory control data independent of the security cell state.
