GAL22V10D-15LPNI Présentation
A PLD (Programmable Logic Device) is a digital integrated circuit whose logic function and interconnects are defined by the user after manufacture. Within the IC taxonomy, PLDs sit between fixed-function logic gates and full FPGAs: a PLD implements combinational and registered logic via a programmable AND/OR array with dedicated output macrocells, whereas an FPGA uses distributed look-up tables, block RAM and soft cores. The "22V10" naming convention means 22 inputs (12 dedicated + 10 feedback) feeding 10 macrocells with variable drive polarity — this generic footprint is supported across multiple vendors, including Lattice, Atmel/Microchip and AMD, giving designers drop-in second sources.
Key features of the GAL22V10D-15LPNI include 10 ns / 15 ns propagation delay grades, electrically erasable (E2CMOS) technology allowing 100+ reprogram cycles, in-system programmable architecture, a built-in security bit to lock the pattern, and low CMOS standby current with TTL-compatible I/O. The device is functionally and parametric compatible with standard bipolar and CMOS 22V10 devices, including the classic PAL22V10.
The GAL22V10D combines a high-performance CMOS process with Electrically Erasable (E2) floating gate technology. The 10 OLMCs are individually configurable as registered, combinatorial, or I/O with selectable output polarity, and feedback paths allow buried state machines. Unlike UV-erasable EPROM-based 22V10s, the E2CMOS cell can be erased electrically in-circuit, which simplifies prototyping and field upgrades.
Typical applications include address decoding and glue logic for microprocessor systems, state-machine and sequencer controllers, bus arbitration logic, peripheral interface adapters, and industrial control replacements of legacy bipolar PALs. Through-hole PDIP packaging suits legacy boards, test fixtures, and aerospace/industrial designs where DIP is preferred over surface mount.
When designing, remember the GAL22V10D-15LPNI requires a single 5 V supply (VCC = 4.75 V to 5.25 V) and the JEDEC-standard 22V10 fuse map. Use a Lattice-approved programmer (e.g., ispGAL22V10-compatible) to load the pattern; the security bit, once programmed, prevents readback of the device.

Applications typiques
GAL22V10D-15LPNI convient pour 6 applications: Microprocessor Address Decoding & Glue Logic, State-Machine & Sequencer Controllers, Bus Arbitration & Interface Logic, Legacy Industrial Control Replacement, Test & Measurement Fixtures, Aerospace & Defense Avionics (Legacy Sustainment).
Microprocessor Address Decoding & Glue Logic
The GAL22V10D-15LPNI's 12 dedicated inputs plus 10 macrocell feedback paths make it ideal for decoding the upper address bits of 8/16/32-bit microprocessor memory and I/O maps, with the 15 ns tPD comfortably fitting one CPU clock cycle at 33 MHz. Each of the 10 OLMCs can be configured as combinatorial or registered, enabling the device to replace multiple 74LS TTL decoder packages. The E2CMOS technology lets engineers iterate the decode map during prototyping without UV erasure, and the JEDEC-standard 22V10 footprint ensures the part fits existing through-hole DIP boards designed around the original PAL22V10.
Recommandé
State-Machine & Sequencer Controllers
With 10 OLMCs that can be configured as D flip-flops with feedback, the GAL22V10D-15LPNI implements Moore or Mealy state machines of up to 1024 states using the AND/OR array. The 83.3 MHz f_max and 15 ns tPD support high-speed sequencer timing in test equipment and industrial controllers. Industrial temperature grade (-40C to +85C) allows deployment in factory-floor equipment. The E2CMOS security bit locks the design into the device, preventing unauthorized pattern readback in production.
Recommandé
Bus Arbitration & Interface Logic
The 22V10 architecture's registered outputs and bidirectional I/O make the GAL22V10D-15LPNI well-suited for bus arbitration controllers, DMA handshaking, and legacy peripheral bus adapters such as ISA, STD, or VMEbus. The 5 V TTL-compatible I/O directly interfaces with classic peripheral ICs without level shifting. Pin-compatibility with the bipolar PAL22V10 means existing arbitration designs port without PCB changes, while gaining lower power consumption and re-programmability from the E2CMOS cell.
Recommandé
Legacy Industrial Control Replacement
Many industrial controllers designed in the 1980s and 1990s use PAL22V10 or GAL22V10 devices for I/O expansion, signal conditioning logic, and safety interlock decoding. The GAL22V10D-15LPNI provides a form-fit-function replacement for these legacy boards, with the industrial temperature grade suiting factory environments. Through-hole PDIP packaging supports hand-soldered repair and rework on existing equipment. When original PALs are obsolete, the GAL22V10D-15LPNI accepts the same JEDEC fuse map, simplifying field service.
Recommandé
Test & Measurement Fixtures
Through-hole DIP packaging is convenient for test fixtures, evaluation boards, and educational labs. The GAL22V10D-15LPNI plugs into standard 24-pin DIP sockets and is easily reprogrammed via commercial device programmers supporting the 22V10 JEDEC map. The 15 ns tPD allows construction of timing generators, pulse shapers, and custom waveform generators used in bench-top instrumentation. The industrial temperature grade ensures operation in lab and shop-floor environments.
Recommandé
Aerospace & Defense Avionics (Legacy Sustainment)
Many avionics and defense platforms certified in the 1990s and early 2000s contain GAL22V10D devices in through-hole DIP for flight control logic, cockpit display drivers, and navigation interfaces. The GAL22V10D-15LPNI supports sustainment programs maintaining these platforms. Industrial temperature grade (-40C to +85C) suits avionics bays. For new aerospace designs, modern rad-tolerant FPGAs such as the Microsemi RTG4 are recommended, but the GAL22V10D-15LPNI remains valuable for legacy sustainment and test equipment.

Notes de conception
The GAL22V10D-15LPNI requires a single 5 V supply on pin 24, with pin 12 tied to ground. Per the Lattice GAL22V10 datasheet, VCC must remain within 4.75 V to 5.25 V; operation below 4.75 V may cause AC parameter degradation and PROM cell reliability issues. Decouple VCC with a 0.1 uF ceramic capacitor placed within 5 mm of the supply pin, plus a 10 uF bulk capacitor on the board. The E2CMOS standby current is much lower than the original bipolar PAL22V10, but dynamic Icc scales with f_max and capacitive loading on outputs.
Place the GAL22V10D-15LPNI in a 24-pin PDIP socket (e.g., 3M 2400-series or Mill-Max) when used in development or field-serviceable applications, so the device can be removed and reprogrammed. For production boards, direct through-hole soldering is acceptable. Route all 10 OLMC outputs away from the dedicated input pins to minimize crosstalk. The 22V10 architecture has no internal pull-ups on inputs; unused inputs must be tied directly to VCC or GND to prevent floating-input oscillation that increases Icc and may trigger spurious output transitions.
Three common pitfalls with the GAL22V10D-15LPNI: (1) Attempting to program it with a PAL22V10 fuse map generated for a bipolar device — while pin-compatible, the JEDEC map format requires conversion via a Lattice-approved compiler (e.g., ispLEVER classic, or PAL-to-GAL conversion tools). (2) Forgetting the security bit — once programmed, the device cannot be read back, so always archive the original JEDEC file. (3) Mixing DIP and surface-mount footprints across the design — the GAL22V10D-15LPNI is a through-hole DIP; for SMT designs use GAL22V10D-15QJN (PLCC-28) or GAL22V10D-15QPN (TBD package code) variants.
