ATF16LV8C-10JC - 10ns 16V8 EECMOS PLD | Microchip Technology
部品番号: ATF16LV8C-10JC ✗ 生産終了ATF16LV8C-10JC 概要
A programmable logic device, or PLD, is a reconfigurable semiconductor used to implement digital logic functions that would otherwise require multiple gates, counters, decoders, or interface circuits. The ATF16LV8C family combines a compact 16V8 architecture with electrically erasable Flash memory, allowing the logic configuration to be programmed or rewritten after manufacture. Its architecture emulates many 20-pin PAL devices and supports registered, combinatorial, and complex logic configurations.
The ATF16LV8C-10JC provides 10 ns maximum pin-to-pin delay, corresponding to a stated 83.3 MHz performance figure for the 16V8 architecture. Its eight macrocells provide flexible product-term allocation for combinational and registered functions. CMOS- and TTL-compatible interfaces simplify integration with both modern low-voltage logic families and established TTL-based equipment.
Power management is particularly useful in portable or intermittently powered systems. The device offers a pin-controlled power-down mode with a maximum specified current of 5 uA, while typical standby current is 100 nA. These figures help reduce system consumption when the logic does not need to remain continuously active.
Typical applications include interface control, decoder and counter logic, industrial control panels, legacy peripheral emulation, glue logic, programmable address decoding, and compact control sequencers. The 20-pin PLCC package supports through-hole assembly and socket-based legacy system maintenance, while its Flash-based configuration supports nonvolatile reusable logic.
Designers should verify signal timing against the electrical characteristics for the actual operating voltage and temperature. Unused inputs should not float, power and ground connections should follow the datasheet pin-description table, and programming tools should be checked for device-family support. The ATF16LV8C-10JC is most appropriate when a compact, nonvolatile, 10 ns 16V8 PLD is required in a 20-pin PLCC footprint.
This page combines the manufacturer device description, cross-reference findings, package details, and practical engineering guidance to clarify where the ATF16LV8C-10JC fits in legacy control, interface, and programmable-logic systems.

Industrial Control Logic
The ATF16LV8C-10JC is suitable for compact machine-control logic that requires nonvolatile configuration, eight macrocells, and deterministic operation. Its 10 ns maximum pin-to-pin delay supports 83.3 MHz-class logic performance within the stated 16V8 architecture. Install it in the 20-pin PLCC footprint for decoding commands, coordinating interlocks, or sequencing actuators. The 5 uA maximum power-down current can reduce consumption when a machine is idle. For continuous-duty industrial service, verify the commercial temperature grade against the enclosure environment and review timing margins at the actual 3.0 V to 5.5 V supply.
おすすめ
Address Decoding
The ATF16LV8C-10JC can implement configurable address decoding and command qualification in legacy digital systems. Eight macrocells provide enough architecture for multiple product-term combinations, while the 10 ns pin-to-pin delay keeps decode propagation short relative to slower peripheral buses. The Flash-based configuration retains the logic map through power cycles and permits updates without a socketed fuse-based device. Place the PLCC close to the decoded circuitry, route outputs away from high-current switching nodes, and validate each decoded interval against the slowest participating peripheral.
おすすめ
Legacy Peripheral Emulation
The ATF16LV8C-10JC can emulate combinational, registered, or mixed logic functions formerly implemented by multiple 20-pin PAL devices. The 16V8 architecture emulates many common 20-pin PAL configurations, making it useful when restoring industrial or laboratory equipment. Its 10 ns maximum pin-to-pin delay preserves timing margins in older systems, and the electrically erasable configuration allows logic corrections without manufacturing a new mask. Before replacement, compare the original fuse map with the device's supported architecture and verify every registered output, feedback path, and pin assignment against the manufacturer tables.
おすすめ
Interface Control and Translation
The ATF16LV8C-10JC can combine interface qualification, command decoding, and control-signal generation in a single PLD. CMOS- and TTL-compatible inputs and outputs simplify connections between mixed legacy logic families. At a maximum pin-to-pin delay of 10 ns, the device provides useful timing margin for many control and status paths without introducing a separate microcontroller. Use the available I/O structure carefully to maintain required input and output levels, add suitable signal conditioning for long lines, and confirm that the power-down input remains in a defined state during normal operation.
おすすめ
Counter and Sequencer Logic
The ATF16LV8C-10JC supports programmable counter, sequencer, and state-machine implementations within its eight-macrocell 16V8 architecture. The 10 ns pin-to-pin delay helps constrain clock-to-output and combinational delays in compact control sequences. Because the configuration is nonvolatile, startup behavior can be deterministic and does not require an external configuration loader. Choose pin assignments and feedback loops according to the device's registered-output architecture, and validate timing at the highest intended clock rate, the lowest supply voltage, and the worst operating temperature for the selected qualification grade.
おすすめ
Battery-Powered Instrumentation
The ATF16LV8C-10JC can implement low-power measurement, control, and status logic where a 20-pin PLCC package and nonvolatile configuration are useful. Pin-controlled power-down limits the specified current to 5 uA maximum, while typical standby current is 100 nA, helping conserve energy when the instrument is inactive. Its eight macrocells can consolidate decoding and sequencing functions that otherwise require several CMOS packages. Evaluate total standby power including pull resistors and connected interface devices, and use the datasheet power-down truth table to prevent unintended logic states during wake-up and shutdown transitions.

主な差別化要因

設計ノート
The ATF16LV8C-10JC uses a 20-pin PLCC package intended for through-hole assembly or socket use. Confirm the PCB footprint, pin-1 orientation, and socket compatibility before layout release. Keep the device accessible if field reprogramming is expected, provide unobstructed clearance around the package, and follow the datasheet pin-description table for supply and ground connections rather than inferring positions from the family architecture.
Treat every external input and output according to the device's CMOS- and TTL-compatible electrical characteristics. Do not leave unused inputs floating. For long traces, slow edges, or noisy industrial wiring, use series damping, suitable pull devices, and appropriate input conditioning. Validate setup and hold timing at the actual clock rate and verify timing margins at the lowest intended supply voltage and worst environmental condition.
The stated 5 uA maximum power-down current applies to the ATF16LV8C pin-controlled power-down mode, not to the complete powered logic path. Use the manufacturer power-down truth table to define the pin state during normal operation and shutdown. Include external pull networks and connected devices in system-level standby calculations, and ensure the supply remains within 3.0 V to 5.5 V during startup, programming, and normal operation.
The 16V8 family supports several operating modes, so a replacement is not automatically interchangeable merely because the suffix and package appear similar. Confirm the supported fuse map, pin assignment, registered-output behavior, feedback topology, programming algorithm, and timing grade. For ATF16LV8C-15JC, the 15 ns speed grade is 50% slower than the 10 ns target, so it should be used only after a complete timing analysis confirms adequate margin.
