ATF22V10C-7XC - 5V 10-Macrocell 7.5ns PLD | Microchip
MPN： ATF22V10C-7XC ✓ 啟用中ATF22V10C-7XC 概覽
An electrically erasable programmable logic device, or EEPLD, is a semiconductor that stores a logic configuration in nonvolatile memory. It sits between fixed-function logic ICs and field-programmable gate arrays: unlike a conventional PAL or GAL device with fusible links, the ATF22V10C-7XC can be reprogrammed after its logic pattern has been established. Its 10 macrocells provide up to 500 gates for decoding, control, address mapping, interface conditioning, and other moderate-complexity logic.
Key features include a nominal 5 V supply, a 7.5 ns speed grade, 10 user input/output pins, and operation over the commercial temperature range. The 24-pin TSSOP package measures approximately 4.40 mm in body width, making the device suitable for compact PCB layouts where a larger DIP or SOIC package would be inconvenient. Electrically erasable Flash technology also eliminates the one-time programming limitation of fuse-based PLDs.
The ATF22V10C family supports multiple product-term configurations and operating modes for combinational, registered, complex combinatorial, and output-register functions. Its architecture is designed as a superset of the generic 22V10 architecture, supporting migration from compatible 24-pin combinatorial PLDs. The selected -7XC configuration provides a practical balance between operating speed and timing margin in 5 V digital control systems.
Typical applications include industrial control interfaces, peripheral decoding, bus arbitration, legacy bus adapters, keyboard or display controllers, and compact embedded control systems. It is particularly useful when a design needs several decode equations and registered outputs but does not justify the complexity, cost, or static power of a larger FPGA or microcontroller.
PCB design should preserve the device's supply and ground distribution, provide standard decoupling close to the power pins, and account for the 5 V operating requirement. Designers should also validate every programmed function and output state against the logic equations before releasing a production design. A programmable device changes configuration, not the PCB routing rules or the electrical limits of its package.
This page combines the device's core operating specifications, programming and pinout guidance, drop-in replacement considerations, application guidance, and practical PCB design notes to support faster engineering evaluation.

典型應用
ATF22V10C-7XC 適用於 6 應用s: Industrial Address Decoding, Legacy Bus Interface Control, Peripheral Chip Select Logic, Display and Keyboard Control, Embedded Control and Sequencing, Test and Measurement Control.
Industrial Address Decoding
The ATF22V10C-7XC is appropriate for industrial address decoding when the logic system needs several decode equations without allocating a microcontroller or FPGA. Its 10 macrocells provide up to 500 gates, and each output can be assigned 8 to 16 product terms, making the device suitable for selecting chips, peripherals, memory regions, and command strobes. The 7.5 ns propagation delay helps preserve timing margin in address-based control paths. Place the device on a 5 V logic rail, connect unused inputs to defined levels, and route the 24-pin TSSOP footprint with its datasheet-specified supply and ground pins. Commercial operation is specified from 0 °C to 70 °C.
推薦
Legacy Bus Interface Control
The ATF22V10C-7XC can implement command decoding, bus arbitration, and interface state logic for a legacy 5 V bus subsystem. Its 10 user I/O pins are sufficient for compact handshake, acknowledge, and control functions, while the 7.5 ns speed grade supports deterministic decisions between bus phases. The electrically erasable Flash architecture permits logic updates during design verification without replacing a fuse-programmed device. When interfacing the PLD with a microcontroller or peripheral, establish input and output drive expectations in the design, keep the common ground continuous, and test both asserted and deasserted states. Verify timing against the fastest bus edge rather than relying only on the nominal propagation delay.
推薦
Peripheral Chip Select Logic
The ATF22V10C-7XC fits peripheral chip-select and interrupt-routing logic where several qualified outputs must derive from common address and control events. Up to 10 macrocells and 8 to 16 product terms per output provide more flexibility than a basic dual decoder, while the 7.5 ns propagation delay keeps decode delays controlled. Implement the equations in the programming file, reserve sufficient output drive capability for each connected peripheral, and review whether any output requires registered behavior to prevent false selection during initialization. The 24-pin TSSOP package supports compact control boards, although its 0.173-inch body width still requires careful assembly planning between closely spaced components.
推薦
Display and Keyboard Control
The ATF22V10C-7XC can perform scan sequencing, key-code translation, and display multiplexing in compact human-interface designs. Its 10 macrocells support moderately complex combinational and registered functions, and the 7.5 ns propagation delay is useful for scanning multiple inputs and generating deterministic control strobes. Program separate equations for scan state, row enable, and output gating, then validate transitions in a prototype before high-volume assembly. The device operates from a 5 V supply and must remain within its 0 °C to 70 °C commercial range. Its TSSOP footprint is suitable for compact boards, but designers should preserve clearance for programming or test access where that is part of the board plan.
推薦
Embedded Control and Sequencing
The ATF22V10C-7XC is useful as a companion logic device in embedded systems that require a small number of deterministic state or decode functions alongside a microcontroller. Its 10 macrocells can implement sequencing, latch controls, watchdog qualification, or signal conditioning while its 7.5 ns delay provides a defined response interval. Because the device is programmable, engineers can update the logic configuration during bring-up and then freeze the production programming file. Use the microcontroller for sequential software functions and the ATF22V10C for fixed hardware interlocks, ensuring every external output has a defined startup state. Confirm the 5 V interface levels and commercial temperature limit against the enclosure environment.
推薦
Test and Measurement Control
The ATF22V10C-7XC can implement fixed control logic for test equipment, including mode selection, range switching, relay sequencing, and status decoding. The 10 macrocells accommodate multiple Boolean functions, while the 7.5 ns propagation delay supports predictable control-path timing. In a measurement system, use registered outputs where relay or switch sequencing must remain stable during mode changes, and validate every power-up combination rather than only the intended operating path. The 5 V supply is compatible with many legacy logic boards, but noise-sensitive analog sections should retain separate filtering and grounding practices. Keep the commercial 0 °C to 70 °C operating limit in mind when positioning the controller near power stages or enclosed test equipment.

選型指南
設計說明
Use the 24-pin TSSOP land pattern and the exact pin-description table from the ATF22V10C manufacturer datasheet. Do not substitute a 24-pin SOIC or DIP footprint because all three packages contain 24 leads but have different lead spacing and body widths. Place input and output traces away from switching nodes, maintain a continuous ground reference, and follow the datasheet's supply and ground connection recommendations for the package.
The ATF22V10C-7XC operates from a nominal 5 V supply, with the commercial speed range specified at 5 V ±5%. Place standard bypass capacitance close to the supply and ground pins and keep the supply return path short. Confirm that downstream loads, pull-ups, and interface drivers do not create supply droop beyond the device's operating range. The family's low-power figures are useful for standby analysis but should not replace a worst-case active-power calculation for the implemented equations.
Avoid assuming that every 22V10-family device is a direct replacement. Confirm the package, speed suffix, temperature grade, power-down option, I/O assignments, and programming fuse map before substitution. A GAL22V10D comparison may share the generic architecture while using a different physical package or ordering code. Validate the programmed outputs with power-up, reset, and worst-case input-transition tests because a logically equivalent architecture does not eliminate timing or board-level differences.
Treat outputs driving clocks, chip selects, or bidirectional control lines as timing-sensitive even when the 7.5 ns propagation delay appears sufficient on paper. Keep programmed output routing short, avoid sharing narrow buses with unrelated high-current signals, and provide a defined state for every input that can float. If outputs control external loads, verify rise time, fanout, and voltage thresholds under the actual trace loading rather than relying only on the nominal logic delay.
合規資訊
The commercial ATF22V10C-7XC is not presented as an automotive-qualified AEC-Q100 device. RoHS, REACH, lead-free, halogen-free, and conflict-minerals status require confirmation for the exact ordering code and manufacturing lot.
