ATF22V10C-5JC - 500-Gate EE PLD, 10 Macrocells, 5ns | Microchip
N.º de pieza: ATF22V10C-5JC ✓ ActivoATF22V10C-5JC Descripción general
An EE PLD is a programmable logic device whose configuration memory is non-volatile and re-writable. Within the wider semiconductor hierarchy, ATF22V10C sits in the programmable logic family, which sits inside the broader logic IC and programmable logic device categories. A GAL22V10-style device maps a fixed sum-of-products architecture onto 10 macrocells, each with 8 product terms feeding an OR plane plus a configurable flip-flop. That structure makes the ATF22V10C a natural fit for glue logic, control decoding, address decoding and bus arbitration logic that must be re-worked late in a design cycle.
Key electrical features include a 5 ns minimum tPD, 10 macrocells of 500 total gates, a 28-pin PLCC footprint, an input latch feature that holds inputs at their previous logic states, and flash-based in-circuit re-programming. Unlike mask-programmed or OTP alternatives, the ATF22V10C can be updated on the assembly line, which shortens NPI schedules and eliminates disposal of obsolete programmed parts.
Technically, the ATF22V10C is architecturally compatible with the classic GAL22V10 JEDEC fuse map, so existing GAL22V10 pinouts, fusing tables and JEDEC third-party programmer support carry over directly. Microchip publishes the ATF22V10C as the recommended replacement for the GAL22V10, noting that AC and DC characteristics are very similar with only minor differences.
Typical applications include address decoding for memory and peripheral buses, control-plane state machines for industrial and instrumentation equipment, retrofit glue logic around legacy microcontrollers, ASIC prototyping, and interface logic in test and measurement equipment. The 28-pin PLCC package gives short, low-inductance leads that support both hand soldering and reflow at 5 V clock speeds.
When designing around the ATF22V10C, remember that its 10-macrocell architecture maps to classic GAL22V10 JEDEC equations; use a JEDEC-compatible programmer and verify the fuse map against the vendor library before taping out. Place a 0.1 uF decoupling capacitor at each supply pin and keep PLCC leads short to limit ground bounce on fast output transitions.

Aplicaciones típicas
ATF22V10C-5JC es adecuado para 6 aplicacións: Memory and Peripheral Address Decoding, Legacy Industrial Control and Retrofit Logic, Bus Arbitration and Control State Machines, ASIC and CPLD Prototyping Glue Logic, Test and Measurement Equipment Control Front-Ends, Security, Key and Access Control Panels.
Memory and Peripheral Address Decoding
The ATF22V10C-5JC's 10 macrocells and 500 gates are sized for classic memory-select and chip-enable decoding in 8-bit and 16-bit microprocessor systems. Each macrocell provides eight product terms for the AND array feeding a shared OR plane, which maps directly onto the JEDEC GAL22V10 equations that most legacy 8086/8051 peripherals were designed against. With a 5 ns propagation delay at 5 V, the decode path stays short enough to qualify as address valid in most asynchronous bus designs, while the 28-pin PLCC package keeps lead inductance low for clean outputs in long-cable industrial chassis. Because configuration is stored in electrically erasable flash, the decode map can be corrected at the production test stage without scrapping boards, which is a major practical advantage over OTP fuse devices.
Recomendado
Legacy Industrial Control and Retrofit Logic
Retrofitted industrial controllers often inherit a GAL22V10-class glue-logic section, and the ATF22V10C-5JC is the manufacturer-endorsed flash replacement for that part. Microchip guidance confirms the ATF22V10C family is pin-to-pin and JEDEC fusemap compatible with the GAL22V10, so existing boards, backplanes and connector pinouts can be preserved while moving from one-time fuses to electrically erasable flash. The commercial 5 V +/- 5% supply range matches legacy 5 V logic, and the 10 uA typical inactive-state dissipation suits always-powered machinery. In practice the biggest engineering win is field programmability: an integrator can update bitstream logic from a USB-connected programmer during commissioning rather than returning the board to a specialist programming house.
Recomendado
Bus Arbitration and Control State Machines
The ATF22V10C-5JC's fixed sum-of-products architecture with a configurable output flip-flop per macrocell is well suited to arbitration and sequencing logic that must settle deterministically. Ten macrocells can hold a request/grant chain, a priority encoder and an output-enable matrix for shared bus transceivers, all at the 5 ns propagation delay grade. The latch feature holds inputs at their previous logic states, which prevents bus contention during asynchronous grant handshakes where inputs may glitch. Operating from a single 5 V rail keeps the part compatible with classic TTL-level buffers and level shifters, and the 28-PLCC footprint matches the large through-hole legacy boards commonly found in test and instrumentation equipment.
Recomendado
ASIC and CPLD Prototyping Glue Logic
During ASIC or CPLD bring-up, engineers frequently need a small amount of fix-up logic around a fast core that is faster to implement in a discrete PLD than in HDL. The ATF22V10C-5JC fills that role with a 5 ns tPD, enough for address remap, interrupt acknowledge and reset sequencer glue around an early prototype. Its electrically erasable flash means the fix-up can be changed in minutes when the silicon behaviour is revised, and the JEDEC GAL22V10 fuse map means many designers already own a compatible programmer and fuse table. The trade-off is capacity: 500 gates in 10 macrocells covers only modest fix-up logic, so anything larger should move to a small CPLD such as an XC9500 or Lattice MachXO.
Recomendado
Test and Measurement Equipment Control Front-Ends
In instrument control panels, the ATF22V10C-5JC can implement front-panel sequencing, relay drive decoding and status multiplexing where reliability matters more than density. Because the macrocell flip-flops can be clocked from an external strobe, the part can run a small synchronous sequence independent of the main microcontroller, isolating critical timing from the host bus. The commercial 5 V supply tolerance aligns with instrument backplanes that already carry regulated 5 V, and the 28-PLCC package is a drop-in match for the GAL22V10 sockets still found in many older analyzers and oscilloscopes. Electrically erasable flash also simplifies calibration logic revisions, since the instrument vendor can re-program boards in the factory without an OTP programmer.
Recomendado
Security, Key and Access Control Panels
Access-control and key-management panels often need a modest amount of combinational logic to combine reader inputs, validate credentials and drive lock solenoids, and this is exactly where the ATF22V10C-5JC's 500 gates fit. The part can decode reader protocols and generate qualified lock-release pulses with deterministic 5 ns delays and no external clock, while its 10 uA typical inactive dissipation keeps battery-backed panels from wasting standby charge. Security considerations are important here: electrically erasable flash can be read by an attacker with physical access, so this device should not hold long-lived cryptographic keys; it is better suited to control-path logic with keys held in a dedicated secure element. The PLCC package survives the reflow and rework cycles common in locking hardware manufacturing.

Notas de diseño
The ATF22V10C-5JC ships in a 28-PLCC (QCCJ) J-lead package with an 11.51 mm x 11.51 mm body and 0.4 mm pitch leads on a 1.27 mm center span. Place it on the solder side with adequate keep-out for the J-leads and provide a thermal via array under the package center to help heat spread from the 5 V CMOS core. Because PLCC leads are not self-aligning for wave solder, verify lead coplanarity and inspect for solder bridging between the closely spaced J-leads after reflow.
Decouple the single 5 V supply with a 100 nF ceramic placed within 2 mm of the VCC pin, and add a 1 uF to 4.7 uF bulk capacitor close to the device for di/dt margin on output transitions. Estimated supply current: a 5 V CMOS PLD with roughly 10 macrocells active typically draws on the order of a few tens of milliamperes at high toggle rates, so size the trace and plane for at least 50 mA to avoid droop-induced timing failures. Decouple any unused or configured-as-I/O VCC pins per the manufacturer's recommended pattern in the ATF22V10C(Q) datasheet doc0735.
PLCC J-leads are longer than leadless packages and add roughly 5 mm to 8 mm of trace inductance, which becomes a real issue when several outputs toggle simultaneously at high edge rates. Keep ground returns short, use an unbroken ground plane directly under the device, and avoid routing outputs adjacent to the clock or latch inputs. If the design includes a latch or flip-flop configuration, respect the setup and hold windows specified in the ATF22V10C(Q) datasheet, since the J-lead propagation adds delay that is not visible in the logic equations.
The most common mistake is assuming an ATF22V10C can be programmed like a generic GAL22V10 without checking the fuse map and the device family table in the programmer software. Microchip states the ATF22V10C is pin-to-pin and JEDEC fusemap compatible with the GAL22V10, but AC and DC characteristics show a few minor differences, so re-run timing analysis after substitution. Second pitfall: mixing speed grades. A 7 ns or 10 ns substitute changes worst-case path delays, which can break designs that were signed off against 5 ns tPD. Third pitfall: assuming flash content is secure - do not store cryptographic keys in the ATF22V10C.
Place programming-related test pads or a dedicated ISP header close to the device so the configuration can be updated without removing the board, and route these nets away from high-current switching nodes. Keep the 28-PLCC footprint compatible with the legacy GAL22V10 socket pattern so the same board can be populated with either device during transitions, and mark the PCB revision to indicate which family is fitted. Where the design ships through a tube pack, note the tube quantity of 26 pieces for standard PLCC handling and plan moisture handling per the packaging MSL marking.
Información de cumplimiento
RoHS, REACH, lead-free and halogen-free statements were not present in the verified web data for this legacy PLD family, so they are listed as unknown rather than assumed. AEC-Q100 is marked not_applicable because the ATF22V10C is a commercial/industrial logic device, not an automotive-qualified part; the ATF22V10CQ-5JC is the military-temperature variant and was not confirmed as AEC-Q100 qualified in the source data. Microchip's GAL22V10 replacement guidance identifies ATF22V10C/CQ/CQZ as the pin-to-pin, JEDEC fusemap compatible replacement for the GAL22V10.
