ATF22V10C-7JI - 10-Macocell 5V EE PLD | Microchip
MPN： ATF22V10C-7JI ✗ 停產ATF22V10C-7JI 概覽
An EE PLD is a semiconductor whose digital logic function is user-programmed through a configurable internal array. The ATF22V10C-7JI provides 10 macrocells, equivalent to approximately 500 gates according to distributor data. This makes it useful for implementing fixed combinational and registered logic, interfacing legacy systems, consolidating small amounts of glue logic, and providing compact control functions in industrial automation, consumer electronics, and telecommunications equipment.
Key characteristics include a 7.5 ns speed grade, operation from a 5 V input supply, surface-mount construction, and an industrial temperature grade. The family also provides an optional pin-controlled power-down function in which the PD control appears on pin 5 of the PLCC package. Electrically erasable Flash technology gives the device a different programming and update model from one-time-programmable fuse-based PAL and GAL devices.
The ATF22V10C architecture combines programmable input and output structures with dedicated clock and output-enable functions. The device can implement registered logic through its macrocell flip-flops while retaining the familiar JEDEC-compatible 22V10 logic arrangement. This architecture is intended for designs requiring more flexibility than a fixed gate array but less complexity than a modern FPGA.
Typical uses include industrial control logic, communication-interface decoding, address and command multiplexing, legacy peripheral adaptation, and compact system-control functions. Because the device is packaged in a 28-pin PLCC, it is particularly relevant to equipment upgrades that already use that footprint and JEDEC-compatible logic mapping.
When replacing an older GAL22V10 implementation, verify the programmed fuse map, pin-controlled power-down behavior, timing grade, temperature range, and supply requirements against the manufacturer datasheet. The PLCC footprint is suitable for surface-mount assembly, but exposed-pad thermal analysis is not applicable because this package does not contain an exposed thermal pad.
This product page consolidates verified source data, sourcing information, specification comparisons, and application-oriented design guidance. It also distinguishes documented drop-in alternatives from broader functional replacements and identifies the specific details that must be checked before substituting a legacy programmable-logic device.

典型應用
ATF22V10C-7JI 適用於 6 應用s: Industrial Control Logic, Legacy Communications Interface, Consumer Electronics Peripheral Control, Telecommunications Infrastructure Control, Address and Command Multiplexing, Legacy Equipment Retrofit.
Industrial Control Logic
The ATF22V10C-7JI fits compact industrial control blocks because it provides 10 macrocells, approximately 500 gates of logic capacity, and a 7.5 ns propagation delay at a 5 V input supply. It can consolidate state decoding, command qualification, interlock logic, and output-control functions that would otherwise occupy several conventional gate packages. The verified industrial temperature grade is useful in factory equipment, but the obsolete lifecycle status means designers should qualify replacement inventory carefully. A same-footprint ATF22V10C family option may be preferable when preserving a mature 28-pin PLCC control board.
推薦
Legacy Communications Interface
ATF22V10C-7JI is suitable for protocol decoding, signal multiplexing, and control sequencing in legacy communications equipment that uses a 5 V PLCC implementation. Its 10 macrocells can organize address decoding, command translation, and registered control paths, while the 7.5 ns propagation delay provides useful timing margin for moderate-speed logic. Electrically erasable Flash programming also allows controlled design revisions without changing the physical device. Engineers should verify the specific protocol timing, I/O direction assignments, and obsolete-part supply risk before deployment.
推薦
Consumer Electronics Peripheral Control
The ATF22V10C-7JI can implement dedicated control logic for consumer-electronics peripherals where several decode, latch, and sequencing functions must be consolidated on a small board. Its 10 macrocells and approximately 500-gate capacity are sufficient for auxiliary panel, keypad, display, or legacy I/O-control functions without requiring a microcontroller. The 5 V supply and 7.5 ns speed align with established mixed-signal peripheral designs. Because the component is obsolete, new consumer designs should assess lifecycle risk and avoid designing new dependencies where a current programmable-logic solution is available.
推薦
Telecommunications Infrastructure Control
ATF22V10C-7JI is applicable to small telecommunications infrastructure functions such as line-interface control, status decoding, and supervisory logic. The device combines a 5 V supply requirement, 10 macrocells, and a 7.5 ns propagation delay in a surface-mount 28-pin PLCC package, allowing it to fit established line-card and peripheral-control layouts. Electrically erasable Flash technology supports engineering updates, but obsolete lifecycle status requires a careful sourcing plan. Any replacement should be checked against the original fuse map, power-down behavior, and long-term availability requirements.
推薦
Address and Command Multiplexing
The ATF22V10C-7JI is well suited to address decoding, command multiplexing, and register-bank selection in legacy digital equipment. Ten macrocells allow input decode equations, registered outputs, and state transitions to be consolidated in one programmable device, while the 7.5 ns speed grade supports common control-path requirements. The J-lead PLCC package also permits replacement of through-hole-era logic on compatible surface-mount assemblies. Designers must confirm the exact 22V10 fuse map and output polarity because programming-file differences can alter system behavior even when the package and pin arrangement match.
推薦
Legacy Equipment Retrofit
ATF22V10C-7JI is useful when repairing or extending obsolete 22V10-based equipment without redesigning the surrounding PCB. Its 28-pin PLCC J-lead package and JEDEC-compatible 22V10 architecture make it easier to service boards designed around GAL22V10 or earlier Atmel 22V10 devices. The 5 V operation and 7.5 ns propagation delay fit the electrical assumptions of many legacy control cards. For a retrofit, first compare the programmed fuse map, temperature grade, pin-controlled power-down option, supply tolerance, and timing; these checks matter more than package identity alone.

設計說明
Do not select a substitute solely by package and macrocell count. Compare the exact fuse map, input and output assignments, clock configuration, output-enable behavior, and optional power-down function. Microchip states that the ATF22V10C family is pin-to-pin and JEDEC fusemap compatible with GAL22V10, but programming files and minor AC or DC differences still require verification. For ATF22V10C-7JI specifically, confirm whether PLCC pin 5 is used as PD before changing pull-up, pull-down, or unused-pin treatment.
The ATF22V10C-7JI operates from a 5 V input supply. Because the verified distributor data does not provide detailed current limits, AC parameters, or recommended decoupling values, use the manufacturer datasheet for operating-current and supply-noise requirements. Keep the 5 V rail within the device's specified operating range and provide local high-frequency bypass close to VCC and ground pins. The device's low-power behavior should not be inferred for the exact ordering suffix without reviewing its maximum and performance-current tables.
Use the 28-pin PLCC J-lead footprint and verify courtyard, lead pitch, orientation, and solder-profile requirements against the official package drawing before layout or replacement. The verified distributor description gives the body dimensions as 11.51 mm by 11.51 mm, but that dimension alone does not define the complete land pattern. PLCC parts are not leadless and do not require an exposed-pad thermal design; nevertheless, soldering still demands controlled lead coplanarity and adequate assembly-process clearance.
Treat the 7.5 ns speed rating as a device-family timing grade, not permission to use a 7.5 ns external clock without checking the complete datasheet timing table. Registered outputs, feedback paths, setup time, hold time, and propagation-delay variation can reduce system margin. For repairs involving GAL22V10D-7LJI, note that its documented 7 ns rating is faster by 0.5 ns, but that difference does not guarantee identical output behavior under every transition and loading condition.
合規資訊
The supplied verified data does not state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is not applicable to this non-automotive legacy PLD; the verified source identifies an industrial temperature grade rather than automotive qualification.
