ATF22V10C-10JC - 10ns 5V EEPROM PLD | Microchip
部品番号: ATF22V10C-10JC ✓ 生産中ATF22V10C-10JC 概要
A programmable logic device is a semiconductor that stores a configured logic function in nonvolatile memory. The ATF22V10C belongs to the PLD family within the broader logic IC and semiconductor hierarchy. Its product-sum-of-products architecture is intended for compact control, decoding, and glue-logic implementations where a small gate count and user-programmable function provide an efficient alternative to a general-purpose microcontroller.
The -10JC grade is specified for 10 ns operation from a nominal 5 V supply. The ATF22V10C family offers speed options down to 5 ns and power dissipation as low as 10 µA typical. An integrated latch feature holds inputs at their previous logic states, while electrically erasable Flash technology supports repeated configuration changes during development and system updates.
Atmel developed the ATF22V10C using high-performance CMOS electrically erasable Flash technology. Microchip support material identifies the ATF22V10C family as pin-to-pin and JEDEC fusemap compatible with the GAL22V10, providing a practical migration path for designs using that legacy PLD architecture. Exact AC and DC limits must be checked against the manufacturer datasheet for the selected operating range.
Typical uses include address decoding, control-signal generation, state-machine sequencing, interface adaptation, and general-purpose fixed logic in industrial control, communications, instrumentation, and embedded systems. Its 10 macrocells provide enough logic density for compact Boolean functions, while the 28-pin PLCC package supports conventional through-hole board construction.
For a new design, confirm the required fuse map, supply tolerance, temperature grade, and timing budget before assigning the device. Programming tooling must support the ATF22V10C architecture and the required JEDEC-compatible fuse map. Leave programming-test access and power-discharge paths compatible with the manufacturer reference configuration.
This page combines package and performance details, replacement guidance, application-specific engineering guidance, and a parameter comparison to support design selection and legacy-board maintenance. It also distinguishes exact drop-in options from devices that require different packages or timing.

主な用途
ATF22V10C-10JC の用途: 6 件s: Address Decoding, Industrial Control Sequencing, Interface and Bus Control, Instrumentation Signal Routing, Legacy Board Maintenance, Communications Control Logic.
Address Decoding
ATF22V10C-10JC fits address-decoding logic because its 10 macrocells can implement compact decode equations for memory, peripheral, or bus-selection signals. The device operates from a nominal 5 V supply and provides a 10 ns target speed, allowing the decoded outputs to meet typical control-path timing when the system clock and peripheral access time provide adequate margin. Electrically erasable Flash configuration also permits logic changes during prototype debugging without a new fuse-programmed package. The 28-pin PLCC footprint is convenient for through-hole legacy boards, although designers should compare every pin against the manufacturer datasheet and verify the JEDEC-compatible fuse map before production programming.
おすすめ
Industrial Control Sequencing
The ATF22V10C-10JC can implement deterministic control sequences, mode-enable logic, and latch-based state transitions in industrial equipment. Its 10 macrocells and 500 gates provide sufficient capacity for several interacting Boolean functions without a larger FPGA or microcontroller. A 10 ns propagation target supports control logic operating well below the throughput limits of many main processors, while the integrated latch feature helps preserve state when a clock is absent or a control stage is intentionally held. For machinery, confirm the exact commercial or industrial temperature range, supply tolerance, and isolation requirements before choosing this package and grade.
おすすめ
Interface and Bus Control
ATF22V10C-10JC is useful for interface adaptation where several control signals must be translated, qualified, or combined around an older bus architecture. The 22V10 device can implement product-of-sums and sum-of-products functions using 10 macrocells, while its 10 ns speed provides a defined timing target for ordinary control and handshake paths. Electrically erasable Flash configuration makes it practical to correct logic polarity or update interface behavior during validation without relying on irreversible fuse links. Designers should use the manufacturer's programming documentation to confirm logic polarity, unused-pin treatment, power-up behavior, and compatibility with the surrounding 5 V interface.
おすすめ
Instrumentation Signal Routing
The ATF22V10C-10JC can route, latch, and combine digital control signals in measurement instruments where a fixed configuration is more practical than flexible microcontroller software. Its 500-gate, 10-macrocell implementation is sufficient for front-panel state logic, range-selection control, trigger conditioning, and instrument-mode sequencing. The nominal 5 V operation and 10 ns target align with conventional TTL-compatible digital systems, subject to the exact input and output limits in the datasheet. Flash-based configuration allows the same device family to support several instrument variants through revised fuse maps, making the ATF22V10C useful in controlled production environments.
おすすめ
Legacy Board Maintenance
ATF22V10C-10JC is particularly useful for maintaining legacy boards because the ATF22V10C family is described as pin-to-pin and JEDEC fusemap compatible with the GAL22V10. A failed or obsolete one-time-programmable PLD can therefore be replaced by a reprogrammable Flash-based device when the package, timing, and electrical conditions match. The -10JC grade targets 10 ns operation and the same 10-macrocell, 500-gate architecture, preserving the original design intent. Before substitution, compare the old and new pin descriptions, programming polarity, power-up behavior, and temperature requirements, then verify the generated fuse map against the original logic equations.
おすすめ
Communications Control Logic
ATF22V10C-10JC can implement compact command decoding, carrier-enable logic, timeout indicators, and protocol framing functions in communications equipment. The 10 ns target is suitable for many low- and medium-speed control paths, while the latch feature helps retain inputs during non-clocked operating phases. Because the ATF22V10C uses electrically erasable Flash memory, product variants and field-upgradeable prototypes can share the same programmable architecture without separate one-time fuse programming. Designers should verify output timing against the associated protocol controller, account for board-level delay, and ensure the selected 5 V operating range matches every interface connected to the PLD.

設計ノート
Assign all 28 PLCC connections from the manufacturer pin-description table and verify orientation against the package drawing. The ATF22V10C family is associated with GAL22V10 pin compatibility, but designers should still check every supply, programming-test, clock, and output connection before layout release. Keep programming-test access routed where a socket or fixture can reach it, and follow the reference programming configuration for handling unused pins and power-up states.
The -10JC grade has a 10 ns target speed, but system timing depends on the complete path through the PLD, board traces, and receiving device. Build the timing budget from the manufacturer's propagation-delay and output-transition limits, then add receiver setup or hold requirements. Use the 7 ns family grade only when the extra nominal margin is necessary; faster propagation can alter hold-time assumptions and should not be selected solely from the headline speed rating.
Do not transfer a GAL22V10 fuse file solely because the devices share the 22V10 architecture. Microchip support material identifies ATF22V10C as pin-to-pin and JEDEC fusemap compatible with GAL22V10, but supply limits, timing, qualification, and device-specific programming details can differ. Compare the exact old and new datasheets, compile from the original equations when possible, and electrically test the programmed function before deploying it in production.
