ATF22V10C-7JC - 500-Gate 7 ns EE PLD | Microchip Technology
料号： ATF22V10C-7JC ✗ 停产ATF22V10C-7JC 概述
An electrically erasable PLD is a user-programmable logic device whose configuration is stored in nonvolatile memory. In the broader semiconductor hierarchy, the ATF22V10C-7JC is a PLD, then a programmable logic device, then an integrated circuit, and finally a semiconductor. Its ten macrocells make it suitable for compact glue-logic implementations, pin mapping, control decoding, and other functions that can be consolidated into one device rather than implemented with multiple conventional logic ICs.
The verified product information identifies the device as a 22V10-series EE PLD with 500 gates, 10 macrocells, a 5 V operating supply, and a 7 ns speed designation. A separate distributor listing describes the propagation delay as 7.5 ns, so the two published figures should be checked against the applicable datasheet revision and test conditions before using the timing figure for a safety-critical design. The family documentation also describes electrically erasable flash memory, low-power operation, and speeds down to 5 ns across the broader ATF22V10C range.
The ATF22V10C architecture provides multiple product-term configurations for the ten output macrocells. Microchip documentation states that the family supports programmed operating modes and that related ATF22V10CZ and ATF22V10CQZ devices form a superset of generic 22V10 architectures. The ATF22V10C series also offers an optional pin-controlled power-down function; in the PLCC package, the power-down signal is identified at pin 5 in the manufacturer documentation.
Typical uses include industrial control logic, interface decoding, legacy peripheral emulation, counter or state-machine implementation, and compact control logic in otherwise discrete-logic systems. The 28-pin PLCC footprint is especially relevant to maintenance and redesign work involving boards designed around the classic 22V10 architecture. Its nonvolatile, electrically erasable configuration also supports repeatable engineering changes without a dedicated ultraviolet-erase step.
When designing around the ATF22V10C-7JC, preserve the manufacturer's pin assignment and programming-device requirements, and do not substitute a PLD solely because its gate count is similar. Verify the JEDEC fuse-map compatibility, supply voltage, macrocell product-term allocation, active levels, timing grade, and temperature designation against both the target and proposed replacement datasheets. The verified data does not supply exact package dimensions beyond the 28-pin PLCC identification, so mechanical drawings should be taken from the official package documentation.
This page combines the verified manufacturer and distributor information, genuine cross-reference candidates, application guidance, and pin-compatibility cautions rather than repeating raw catalog data alone. It also separates confirmed device facts from fields that remain unavailable, helping engineers evaluate this legacy PLD and any replacement before committing a board layout or production order.

典型应用
ATF22V10C-7JC 适用于 6 应用s: Industrial Control Logic, Interface and Signal Decoding, Legacy Peripheral Emulation, Counter and State-Machine Control, Instrumentation and Measurement Control, Data and Communication Equipment.
Industrial Control Logic
The ATF22V10C-7JC fits compact industrial control logic because it combines 10 macrocells with a 7 ns speed grade at 5 V. It can implement decoded control functions, interlocks, state-machine transitions, or discrete-logic consolidation without multiplying the number of conventional gate packages. The 28-pin PLCC format also supports board-level replacement within established 22V10 designs. Before deployment, verify the worst-case propagation path, output loading, industrial temperature limits, and the optional pin-controlled power-down behavior. Because this is a legacy programmable architecture, preserve the programmed fuse map and validate timing against the exact manufacturer datasheet rather than relying only on the distributor speed label.
推荐
Interface and Signal Decoding
ATF22V10C-7JC is appropriate for translating or qualifying signals between older logic domains when the design needs programmable decoding rather than a fixed gate network. Ten macrocells provide enough capacity for multiple decode and registered logic functions, while the 7 ns grade can support shorter combinational paths than slower 22V10 options. Engineers should confirm active-high and active-low conventions, input thresholds at 5 V, output drive requirements, and the proposed device's fuse map. The PLCC package and JEDEC-compatible 22V10 architecture can simplify maintenance replacement, provided timing and power behavior are revalidated rather than assumed from the family name.
推荐
Legacy Peripheral Emulation
The ATF22V10C-7JC can support compact peripheral emulation when an obsolete GAL22V10-class logic function must be recreated on an existing board. Its 500-gate density and 10 macrocells cover typical address decoding, register-selection, and glue-logic functions, while the electrically erasable flash configuration permits repeatable design revisions without ultraviolet erasure. Microchip identifies the ATF22V10C family as pin-to-pin and JEDEC-fusemap compatible with GAL22V10 devices, but also warns that minor AC and DC differences exist. Validate power-up behavior, I/O levels, timing margins, and the programmed fuse map on every revision before using it as a maintenance replacement.
推荐
Counter and State-Machine Control
A 7 ns ATF22V10C-7JC can implement counters, finite-state machines, command sequencers, and peripheral-control logic where deterministic combinational paths are needed. The ten macrocells allow several state or output functions to be consolidated in one 28-pin PLCC, reducing inter-IC coordination compared with separate counter and decoder packages. Timing analysis must include the device's propagation delay, setup and hold requirements, clock skew, and the selected speed-grade limits. The verified sources disagree between a 7 ns speed designation and a 7.5 ns reported propagation delay, so the conservative figure should be used until the exact datasheet test conditions are confirmed.
推荐
Instrumentation and Measurement Control
ATF22V10C-7JC can be used in instrumentation for front-panel sequencing, status decoding, timing qualification, or isolated command routing around a larger controller. The 5 V supply aligns with conventional TTL and CMOS logic, and the 7 ns class provides useful timing margin compared with 10 ns and 15 ns family alternatives. However, measurement systems often demand precise thresholds, low noise, reference control, and fault containment that must be verified at the system level. Use the device for bounded digital logic rather than analog precision functions, and confirm supply tolerance, output loading, temperature behavior, and power-down state before insertion into a safety-sensitive instrument.
推荐
Data and Communication Equipment
The ATF22V10C-7JC is suitable for legacy communication equipment requiring programmable bus decoding, data routing, and control-signal generation. Consolidating these functions in one 500-gate PLD can simplify boards whose original design used GAL22V10-class devices. The verified Microchip support information specifically identifies ATF22V10C-family parts as pin-to-pin and JEDEC-fusemap-compatible replacements for GAL22V10, making the device relevant to equipment maintenance. Designers must still review differences in AC and DC characteristics, check whether the target uses the optional power-down pin, and reproduce the original fuse map or regenerate and validate an equivalent configuration.

设计说明
Do not assume that matching the 28-PLCC footprint and 22V10 name guarantees an exact substitute. Confirm the fuse map, power-down pin, active logic levels, supply limits, output timing, and temperature grade for both devices. Microchip specifically warns that GAL22V10 replacements have similar but not necessarily identical AC and DC characteristics. Preserve the original programmed configuration or regenerate and validate the logic before production use.
Use the official PLCC land pattern rather than deriving it from the catalog body size. Confirm pin 1 orientation against the package drawing and socket or solder-joint geometry before fabrication. The verified data identifies a 28-pin PLCC measuring 11.51 mm by 11.51 mm but does not provide a complete verified numbered pin table, so PCB pin assignment must be cross-checked against the official ATF22V10C(Q) datasheet and the package drawing.
Analyze every critical path using the conservative timing specification until the discrepancy between the 7 ns speed designation and the reported 7.5 ns propagation delay is resolved. Include macrocell product-term propagation, setup and hold requirements, clock uncertainty, output loading, and supply tolerance. For slower 10 ns or 15 ns alternatives, quantify the reduced timing margin and verify that the entire clock-to-output or input-to-output path still meets the system requirement.
Plan a stable 5 V rail and verify the device's actual operating and absolute-maximum supply limits from the exact datasheet. If the optional power-down input is used, account for its defined state on the PLCC package, which the manufacturer identifies at pin 5. Decoupling and rail-sequencing details are not present in the supplied excerpts, so they must be taken from the official application guidance rather than inferred from generic PLD practice.
合规信息
The verified data does not provide explicit RoHS, REACH, lead-free, halogen-free, or conflict-minerals statements for the exact ATF22V10C-7JC ordering code. This device is an industrial-temperature logic IC and is not presented as an AEC-Q100 automotive-qualified variant.
