ATF16LV8C-10PC 10ns EECMOS PLD | Microchip Technology
부품 번호: ATF16LV8C-10PC ✗ 단종ATF16LV8C-10PC 개요
A programmable logic device, or PLD, is a semiconductor that stores a Boolean logic function as a configuration rather than implementing that function in fixed gates. The ATF16LV8C belongs to the simple PLD hierarchy, combining AND-array and OR-array logic resources with a registered output structure. It can replace 16R8-family devices and many 20-pin combinatorial PLDs when the design fits the available eight-output architecture.
Key features include a maximum propagation delay of 10 ns, CMOS and TTL-compatible inputs and outputs, a pin-controlled power-down mode with a maximum specified power-down current of 5 microamperes, and typical standby current of 100 nA. Software-selected modes allow the same physical device to implement multiple combinational logic arrangements. The 20-pin DIP package supports conventional through-hole assembly and prototype-board implementation.
The ATF16LV8C uses Atmel's EECMOS architecture with electrically erasable flash-memory technology for nonvolatile configuration. This permits a programmed logic function to be retained while allowing the device to be reprogrammed when a design revision changes the implemented equations. Eight product terms are assigned to each of the eight outputs, making the device appropriate for compact combinational control, decoding, and signal-routing functions rather than large sequential systems.
Typical applications include industrial control logic, interface decoding, legacy peripheral control, embedded system glue logic, and replacement of small PAL or combinatorial PLD designs. A 10 ns pin-to-pin delay makes the device suitable for control and decoding paths where compact implementation and legacy package compatibility are more important than the density or configuration flexibility of a larger FPGA.
When designing around the ATF16LV8C-10PC, verify every input and output assignment against the manufacturer's pin-description table and preserve the required programming-device interface and power conditions. The 10 ns speed grade is important when choosing a replacement because slower members of the same family are not automatically equivalent drop-in choices.
This page organizes the manufacturer's architectural details, verified package and speed information, practical application guidance, and replacement constraints into a design-focused reference for engineers maintaining programmable-logic-based equipment.

일반적인 애플리케이션
ATF16LV8C-10PC 적합 용도: 6 애플리케이션s: Legacy Industrial Control Logic, Interface Decoding and Signal Routing, Peripheral Control and Glue Logic, PAL and Combinatorial PLD Replacement, Test and Measurement Control Panels, Embedded System Support Logic.
Legacy Industrial Control Logic
The ATF16LV8C-10PC fits legacy industrial control boards that require compact combinational decoding, interlock logic, or command routing around an older controller. Its eight macrocells and eight product terms per output can consolidate small Boolean functions without replacing the installed control architecture. The 10 ns maximum pin-to-pin delay supports deterministic control paths, while the 20-pin plastic DIP package simplifies repair and prototype-board replacement. Electrically erasable flash-memory configuration permits controlled field updates when operating logic must be revised.

Interface Decoding and Signal Routing
The ATF16LV8C-10PC is useful for decoding address, command, interrupt, or handshake signals into fixed logic outputs. Eight outputs, each with eight product terms, provide enough capacity for compact combinational routing between a host controller and peripheral circuitry. The device's 10 ns pin-to-pin delay helps preserve margin in short control paths, while CMOS- and TTL-compatible interfaces align with established logic families. Its three software-selected modes make it possible to tailor the implemented equations to different board functions.
추천
Peripheral Control and Glue Logic
The ATF16LV8C-10PC can implement the fixed Boolean glue between a microprocessor and older peripherals, including latch enables, chip selects, reset qualifiers, and status multiplexing. Its electrically erasable configuration supports design revisions without replacing the device family, while the 20-pin DIP footprint matches legacy through-hole hardware. The 10 ns speed grade is suitable for many control and decode paths, although engineers should verify setup and hold timing in the complete system. Its pin-controlled power-down option can reduce consumption when the peripheral bank is inactive.
추천
PAL and Combinatorial PLD Replacement
The ATF16LV8C-10PC is appropriate for replacing 16R8-family logic and many 20-pin combinatorial PLDs when the original equations fit the device's eight-output, eight-product-term architecture. The manufacturer datasheet explicitly identifies this replacement capability, reducing the need to redesign around a larger programmable-logic device. A 10 ns maximum pin-to-pin delay provides a timing advantage over slower family grades, and electrically erasable flash memory allows configuration changes during maintenance. Existing boards can benefit from reduced obsolete-part exposure when compatibility checks pass.
추천
Test and Measurement Control Panels
The ATF16LV8C-10PC can implement front-panel state decoding, instrument mode selection, relay-command qualification, or interlock logic in test and measurement equipment. Eight outputs are sufficient for compact command distribution, and the 10 ns pin-to-pin delay supports fast control decisions. The through-hole 20-pin DIP package remains practical for serviceable instrument boards, while nonvolatile programmable configuration supports calibration of logic behavior without replacing the device. The pin-controlled power-down function can help limit standby consumption when an instrument enters a low-power state.
추천
Embedded System Support Logic
The ATF16LV8C-10PC can provide compact support logic around microcontrollers, including reset distribution, peripheral selection, alarm qualification, and multi-signal decode functions. Its electrically erasable flash-memory configuration allows the logic map to be updated during firmware qualification or field maintenance. The 10 ns delay is useful for short control intervals, and the 20-pin DIP format remains convenient for prototype carriers and legacy repair assemblies. For new dense designs, a CPLD or FPGA should be considered when sequential logic, more I/O, or higher configurability is required.

설계 노트
Do not treat every ATF16LV8C suffix as interchangeable. The -10PC ordering code identifies a 10 ns speed grade in a 20-pin plastic DIP package, while other suffix combinations can change speed or package. Confirm the ordering code, package drawing, pin names, programming interface, and AC limits together before approving a replacement. This is particularly important for older designs where the schematic may show only a generic ATF16LV8C designation.
Use the manufacturer's pin-description table to assign configuration-control and programming signals because some functions vary by operating mode. Preserve the required programming-device connections and avoid adding undocumented loading to I/O pins used during programming. For through-hole assembly, maintain adequate spacing around the 0.300-inch, 7.62 mm pitch DIP footprint and observe the package dimensions shown in the manufacturer drawing.
Decide whether the pin-controlled power-down function is required during the board's inactive state. The manufacturer specifies up to 5 microamperes in power-down mode and approximately 100 nA typical standby current, which can be valuable in battery-backed equipment. Ensure the controlling signal remains in a defined state at power-up and that external pull resistors do not create an unintended power-down condition.
