ATF22V10C-5JX - 5ns 500-Gate EE PLD | Microchip Technology
MPN: ATF22V10C-5JX ✓ Hoạt độngATF22V10C-5JX Tóm tắt
A programmable logic device, or PLD, is a semiconductor whose digital function is defined by stored programming data rather than fixed logic. The ATF22V10C belongs to the simple PLD hierarchy: PLD > simple PLD > SPLD > electrically erasable PLD. Compared with a mask-programmed PAL device, its Flash-memory configuration can be changed during development, simplifying logic revisions, prototype corrections, and production programming workflows.
Key features include 10 macrocells, approximately 500 gates, a 5 ns speed grade, a 166 MHz stated maximum frequency, and 5 V operation. The electrically erasable Flash architecture retains the programmed function without continuous electrical rewriting. According to the manufacturer datasheet, power dissipation can be as low as 10 uA typical, making the device useful where low standby consumption is valuable. A pin-controlled power-down feature is also available, with the PD function located on pin 5 for PLCC packages.
The ATF22V10C-5JX is an older, compact CMOS PLD rather than a field-programmable gate array. Its 10 macrocells provide substantially less logic capacity than modern CPLDs and FPGAs, but the 5 ns speed class supports faster decision and decoding paths than slower SPLD grades. The main design trade-off is fixed logic capacity: complex state machines, wide arithmetic functions, and large parallel interfaces may exceed the available macrocells even when the propagation delay is suitable.
Typical applications include industrial control address decoding, peripheral-chip-select generation, asynchronous interface adaptation, embedded reset and power sequencing, test-fixture control, and compact legacy-controller support. Because the device is electrically erasable, it is especially useful for bridge or glue logic that must evolve independently of a larger system-on-chip. Its J-lead PLCC package also provides a practical surface-mount option for boards that cannot accommodate a through-hole DIP package.
Designers should confirm that the required Boolean equation set fits the 10 macrocells and should verify the JEDEC-compatible fuse map before replacing a GAL22V10 or designing a new board. Programming tooling and the correct ATF22V10C device family must be selected. The 5 V supply, 5 ns timing grade, and PLCC footprint should all be checked against the existing schematic and PCB library before procurement.
This product page consolidates manufacturer specifications, distributor pricing, package information, and verified replacement information. It also provides practical selection guidance for ATF22V10C speed grades and clearly distinguishes verified drop-in candidates from options that change speed grade, temperature grade, package, or device architecture.

Ứng dụng tiêu biểu
ATF22V10C-5JX phù hợp cho 6 Áp dụngs: Industrial Address Decoding, Peripheral Chip-Select Control, Embedded Interface Adaptation, Power and Reset Sequencing, Legacy Controller Support, Test and Measurement Fixture Control.
Industrial Address Decoding
The ATF22V10C-5JX fits industrial address decoding because it combines 10 macrocells, approximately 500 gates, and a 5 ns propagation-delay grade in a 28-pin PLCC package. It can decode I/O or memory-selection signals and generate chip-select or write-enable logic without consuming a complete microcontroller. The 166 MHz stated device frequency provides timing margin for address decoding at moderate system-clock rates. Before implementation, engineers must prove that the equations fit 10 macrocells and confirm the available operating-temperature grade against the industrial environment.
Được đề xuất
Peripheral Chip-Select Control
The ATF22V10C-5JX can generate chip-select, read-enable, and write-enable strobes for older peripheral buses where a programmable-logic solution is simpler than a microcontroller. Its 10 macrocells provide enough capacity for multiple decoded control functions, while the 5 ns speed grade helps preserve setup time at a 166 MHz-class internal operating point. The electrically erasable Flash configuration permits late design corrections without replacing the device. Final implementation requires pin-level verification from the manufacturer datasheet and a check that every decoded equation fits the device architecture.
Được đề xuất
Embedded Interface Adaptation
The ATF22V10C-5JX is useful for adapting a legacy interface to a newer control scheme because its electrically erasable configuration can implement combinational and registered glue logic without a fixed mask pattern. With 10 macrocells and a 5 ns speed grade, it can handle protocol qualification, signal translation, and state-transition assistance while the main controller manages higher-level behavior. The device is best suited to modest logic depth rather than complete protocol engines. Engineers should validate setup and hold timing against the exact 5 V operating conditions and the temperature grade selected for the product.
Được đề xuất
Power and Reset Sequencing
The ATF22V10C-5JX can implement deterministic reset release, power-enable sequencing, and fault-flag interlocks in a mixed-signal or embedded control system. Its 5 ns propagation-delay grade helps limit uncertainty in control paths, while the optional pin-controlled power-down function provides a direct way to reduce consumption when the surrounding system is inactive. The architecture is appropriate for a small number of sequencing states, not a large power-management controller. Logic equations and timing must be checked against the power rails and signals actually used by the board.
Được đề xuất
Legacy Controller Support
The ATF22V10C-5JX can support legacy controllers by generating status, interrupt, latch, and bus-cycle signals that would otherwise consume substantial microcontroller firmware and I/O resources. With 500 gates and 10 macrocells, it is well suited to bridge logic around GAL22V10-class or similar control structures. Microchip identifies the ATF22V10C family as pin-to-pin and JEDEC fusemap compatible with GAL22V10 replacements, which is useful in migration planning. The engineer must still compare exact package, temperature, timing, and programmed fuse data.
Được đề xuất
Test and Measurement Fixture Control
The ATF22V10C-5JX can consolidate fixture-control logic such as relay selection, measurement-enable signals, range selection, and status decoding. Its 5 ns speed grade permits short combinational paths, while electrically erasable Flash programming allows the same device to support multiple fixture configurations after verification. The 28-pin PLCC package provides a surface-mount J-lead option, although the library lacks a canonical PLCC-28 drawing. Designers should confirm every package pin, the fuse map, and the power-down state before integrating the device into automated test equipment.

Ghi chú thiết kế
Do not treat every ATF22V10C ordering code as an unconditional substitute. The target is explicitly ATF22V10C-5JX in a 28-pin PLCC package. Compare the complete suffix, package, temperature range, and supply conditions before substitution. The 5 ns family member is suitable only when the installed logic does not depend on undocumented differences between ordering codes.
Use the manufacturer package drawing rather than a generic PLCC symbol when creating or reviewing the PCB footprint. The verified package is 28-pin PLCC with J-leads and a body size of 11.51 mm by 11.51 mm. Confirm lead pitch, pad dimensions, courtyard clearance, and orientation directly from the datasheet because the supplied snippets do not provide a complete land pattern.
Validate both logic capacity and timing before selecting the device. Ten macrocells and approximately 500 gates may be insufficient for a complex state machine even though the 5 ns propagation delay appears fast. Build the Boolean equations, check product-term sharing and registered outputs, and simulate worst-case paths with realistic board and interface delays.
The manufacturer datasheet states that power dissipation can be as low as 10 uA typical. This value should not be interpreted as the active current for every configuration. Review the datasheet operating-current conditions, I/O loading, output state, and the optional PLCC pin 5 power-down function for the actual design. Ensure unused inputs are in valid states and that the board's 5 V rail meets required tolerances.
