ISPGAL22V10C-15LJI

Programmable Logic Device Pld Overview

The Lattice Semiconductor ispGAL22V10C-15LJI is a discontinued in-system programmable GAL device manufactured using E²CMOS technology. It operates at a core voltage of 1.8V and features 10 I/Os with 22 inputs within a 28-pin PLCC package. The -15 speed grade indicates a maximum propagation delay of 7.5 ns and a maximum operating frequency of 166 MHz. Key electrical parameters include a typical standby current of 150 µA and an operating supply voltage range of 1.65V to 1.95V.

Programmable Logic Device Pld Feature Summary

• E²CMOS architecture providing high-speed performance (max 166 MHz) with low power consumption.
• In-System Programmability (ISP) via IEEE 1149.1 (JTAG) and IEEE 1532 standards.
• Configurable Output Logic Macrocells (OLMCs) supporting registered or combinatorial modes with individual product terms.
• 5V tolerant I/Os allowing interface with 3.3V, 2.5V, and 1.8V logic levels.

Programmable Logic Device Pld Applications

• DMA control logic
• State machine implementation
• High-speed graphics processing interfaces
• Software-driven hardware configuration

Programmable Logic Device Pld Procurement Notes

This component has been officially discontinued by Lattice Semiconductor under Product Change Notification (PCN) #09-10. Verification of the specific ordering suffix 'I' confirms it belongs to the Industrial temperature grade (-40°C to +105°C). Sourcing requires checking for legacy stock or authorized distributors holding remaining inventory, as new manufacturing is no longer available.

Programmable Logic Device Pld Selection Notes

Select this part for designs requiring 1.8V core operation with 5V tolerant I/Os in a 28-pin PLCC form factor. The -15 speed grade offers a 7.5 ns max delay suitable for moderate-speed synchronous logic. Ensure the design accounts for the Industrial temperature range if operating in harsh environments. Verify that the 10 I/O count and 132x44 AND array size meet the logic density requirements.

Programmable Logic Device Pld Part Context

The ispGAL22V10A family serves as a low-voltage successor to the older GAL22V10 series, offering functional compatibility while integrating ISP capabilities. The 'C' suffix denotes the 1.8V core voltage variant, distinct from the 3.3V ('V') and 2.5V ('B') versions. This specific device represents the intersection of low-power CMOS technology and traditional PAL/GAL architecture.

Programmable Logic Device Pld Replacement Considerations

No direct pin-compatible replacements are listed in the official datasheet due to the discontinuation of the entire ispGAL22V10A line. Designers must evaluate modern SPLD families or CPLDs from Lattice or other vendors, ensuring voltage level translation and I/O count compatibility.
