GAL22LV10Z-15QJ

Programmable Logic Device Pld Overview

The GAL22LV10Z-15QJ is a Simple Programmable Logic Device (SPLD) from the Lattice GAL22LV10Z series, manufactured by Lattice Semiconductor Corporation. It features an Electrically Erasable CMOS (E2CMOS) architecture with 22 input lines and 10 output lines, organized into 10 macrocells. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports a maximum propagation delay of 15 ns, corresponding to a maximum operating frequency of approximately 66.7 MHz. Packaged in a 28-pin PLCC (Plastic Leaded Chip Carrier), it is designed for surface-mount installation. The component is classified as a mature product and has reached end-of-life status.

Programmable Logic Device Pld Procurement Notes

This component is officially discontinued by Lattice Semiconductor. Availability is restricted to surplus distributors or secondary markets. Verification of part authenticity and lot traceability is critical due to the end-of-life status. Buyers should confirm RoHS compliance details, as older batches may not meet current environmental standards. Lead times vary significantly based on supplier inventory levels.

Programmable Logic Device Pld Selection Notes

Designers replacing this component should evaluate modern SPLDs or CPLDs from Lattice's current portfolios, such as the ispGAL or MachXO series, which offer enhanced programmability and lower power consumption. Compatibility checks must be performed regarding pinout mapping and electrical characteristics if substituting with other 22V10-compatible devices. Ensure that the replacement package matches the existing PCB footprint or plan for adapter solutions.

Programmable Logic Device Pld Part Context

The GAL22LV10Z-15QJ belongs to the GAL22LV10 family, representing a low-power variant of the classic GAL22V10 architecture. This series was widely used in legacy digital systems before being superseded by more advanced programmable logic technologies. The 'Z' suffix typically denotes specific power or speed grades within the E2CMOS lineup, while 'QJ' indicates the plastic leaded chip carrier package type.

Programmable Logic Device Pld Replacement Considerations

Direct pin-to-pin replacements are limited due to discontinuation. Potential substitutes include the GAL22V10D-15QPN or GAL22V10-15LD, though package differences (PDIP/CDIP vs PLCC) require board modifications. Modern alternatives like the Lattice ispGAL22V10 offer functional compatibility but may differ in electrical parameters and packaging.
