ATF22V10C-7JU - 10-Macrocell 7 ns PLD | Microchip | PLCC
MPN： ATF22V10C-7JU ✓ 啟用中ATF22V10C-7JU 概覽
A programmable logic device is a semiconductor whose internal logic connections are configured through programming rather than fixed during fabrication. The ATF22V10C belongs to the SPLD hierarchy, joining PAL-derived combinational logic with erasable nonvolatile configuration memory. Ten macrocells and 500 gates provide more integration than simple fuse-programmed devices while preserving predictable combinational propagation delays.
The -7JU ordering identifies the 7 ns speed option, industrial temperature construction, and 28-pin PLCC configuration. The device operates from a nominal 5 V supply, with a documented operating range extending from 4.5 V to 5.5 V. The ATF22V10C family also supports speeds down to 5 ns and standby or power-down dissipation as low as 10 uA typical, allowing designs to balance speed against standby power.
The electrically erasable Flash configuration memory distinguishes this device from one-time-programmable fuse-link PLDs. Logic can be revised during development without replacing the package, while the JEDEC-compatible fusemap supports predictable migration from GAL22V10-class designs. The optional pin-controlled power-down function provides another mechanism for reducing current in systems that do not require continuous logic evaluation.
Typical uses include industrial control logic, bus decoding, state-machine sequencing, peripheral interfacing, and compact embedded-control subsystems where a small PLD can consolidate multiple gates. The 28-pin PLCC package is suitable for through-hole board assembly and sockets, while the electrically erasable configuration supports engineering revisions and production programming.
Designers should compare propagation delay against the system timing budget, confirm absolute maximum and recommended operating voltages, and include pull-up or pull-down resistors where required by the selected configuration. The pin-controlled power-down function uses a dedicated PLCC pin and should be checked against the fuse map before PCB changes. This page combines manufacturer specifications, replacement analysis, application guidance, and drop-in comparison information for faster engineering evaluation.

典型應用
ATF22V10C-7JU 適用於 6 應用s: Industrial Control and State Sequencing, Bus Decoding and Address Selection, Peripheral Interface Logic, Embedded System Power Control, Instrumentation and Measurement Control, Legacy GAL22V10 Logic Consolidation.
Industrial Control and State Sequencing
The ATF22V10C-7JU fits compact industrial control logic where a controller needs deterministic combinational decoding or state sequencing without a large FPGA. Its 10 macrocells and 500 gates can consolidate multiple Boolean conditions into one programmed device, while the 7 ns speed grade provides more timing margin than the slower 10 ns and 15 ns family options. The device is placed between field-level inputs and downstream control circuitry, with programmed equations implementing interlocks, mode selection, and sequencing rules. Designers should validate every worst-case signal path against the 7 ns class and confirm the selected temperature suffix for the industrial environment.
推薦
Bus Decoding and Address Selection
ATF22V10C-7JU is useful for decoding bus, address, or enable signals into a limited set of control outputs. Its 10 macrocells can implement multiple sum-of-products terms, allowing several decode conditions to share one package rather than occupying separate gate logic. The 7 ns propagation-delay class is useful when the decode must settle within a short combinational interval. The same 28-pin PLCC outline also makes migration to compatible ATF22V10C speed grades possible when timing, availability, or lifecycle requirements change. Final routing should preserve signal integrity and account for package parasitics around high-fanout control nets.
推薦
Peripheral Interface Logic
The ATF22V10C-7JU can consolidate interface gating, command qualification, and data-route control around legacy peripherals. Its Flash-programmable configuration allows interface equations to be revised during development, while the 7 ns speed class helps minimize delay between a control request and the generated peripheral strobe or enable signal. This is particularly useful when a system needs a compact, fixed-function logic block between a processor and older peripherals. Engineers should map all inputs and outputs through the manufacturer pin-description table, include the required power-supply decoupling, and validate that programmed output states remain safe during reset and power-down transitions.
推薦
Embedded System Power Control
ATF22V10C-7JU can implement power-enable sequencing, reset qualification, and subsystem isolation signals in embedded equipment. Its optional pin-controlled power-down function allows the logic to reduce activity when the associated subsystem is not required, while the electrically erasable Flash configuration supports later design revisions without replacing the IC. The 4.5 V to 5.5 V operating range suits nominal 5 V systems, and the 28-pin PLCC package remains convenient for through-hole assembly. Designers must configure the power-down function correctly, control its PLCC input, and ensure every external rail has an independent defined state during startup and shutdown.
推薦
Instrumentation and Measurement Control
The ATF22V10C-7JU is suitable for fixed control functions in instrumentation, including range selection, mode interlocks, measurement gating, and trigger qualification. A 500-gate, 10-macrocell PLD provides enough logic to replace several conventional gate packages while keeping the implementation compact. The 7 ns class helps maintain predictable relationships between control strobes and acquisition paths. In such designs, separate sensitive analog or timing circuitry from noisy switching nodes, use a stable 5 V rail for the logic, and assign unused inputs according to the manufacturer recommendations. The programmed test vectors should cover boundary conditions at every range and mode transition.
推薦
Legacy GAL22V10 Logic Consolidation
ATF22V10C-7JU can support modernization of GAL22V10-class logic because Microchip identifies the ATF22V10C family as pin-to-pin and JEDEC fusemap compatible with GAL22V10 designs. This makes it useful when consolidating a legacy control or decode section into an electrically erasable Flash device that can be reprogrammed during maintenance. Compatibility still requires checking the old device's pin assignments, AC and DC limits, power-down usage, and programmed fuse map against the ATF22V10C datasheet. For new boards, the 7 ns grade offers additional timing margin over slower ATF22V10C options while retaining the familiar 28-pin PLCC mechanical format.

主要差異化特點
- Faster propagation-delay class within the ATF22V10C family (對比ATF22V10C-10JU)
- Substantially more timing margin than the 15 ns family option (對比ATF22V10C-15JU)
- Retains electrically erasable Flash configuration (對比ATF22V10C-7JI)
- Same nominal speed class with a distinct ordering suffix (對比ATF22V10C-7JC)
設計說明
Build the timing analysis around the 7 ns ATF22V10C-7JU speed grade rather than nominal system clock frequency alone. Include PLCC trace delay, input-buffer delay, output-buffer delay, setup requirements, and any downstream gate delay in each critical path. Slower ATF22V10C replacements can add 3 ns with the -10JU grade or 8 ns with the -15JU grade, which may break an otherwise narrow timing margin.
Provide a stable 5 V rail within the 4.5 V to 5.5 V operating range and place the required bypass capacitors close to the supply and ground pins. If power-down is enabled, control the PLCC power-down input carefully because its activation state depends on the programmed configuration. Ensure all signals connected to the PLD remain in defined states during reset, erase, programming, and shutdown so the external system cannot enter an unsafe or indeterminate condition.
Use the manufacturer PLCC pin drawing and footprint dimensions during PCB layout, especially for socketed or mixed-assembly designs. Keep programmed logic inputs and outputs away from high-current switching nodes, and route the power-down control as a deliberate signal rather than an incidental net. Confirm orientation against the package notch or pin-1 mark, then inspect solder joints and socket contacts because intermittent connections can appear as configuration or logic failures.
Do not assume that the 22V10 family designation alone guarantees an interchangeable substitute. Review the JEDEC fusemap, pin table, AC timing, DC limits, temperature suffix, and power-down configuration before replacing ATF22V10C-7JU. For legacy GAL22V10 migrations, Microchip describes the ATF22V10C as pin-to-pin and fusemap compatible, but minor AC and DC differences still require circuit-level review and complete test-vector validation.
合規資訊
