ATF16V8C-5JX - 5ns EECMOS PLD, 8 Macrocells | Microchip
料号： ATF16V8C-5JX ✓ 量产中ATF16V8C-5JX 概述
An EECMOS PLD is a member of the programmable logic device hierarchy, combining a configurable logic architecture with nonvolatile electrically erasable flash memory. Unlike a fixed-function logic gate array, the ATF16V8C allows the interconnections and registered output behavior to be programmed after manufacture. This family is based on the Atmel-proven EECMOS architecture and is positioned between simple fixed AND-OR logic and larger field-programmable gate arrays.
The ATF16V8C incorporates a superset of generic 16R8 architecture, allowing direct replacement for the 16R8 family and most 20-pin combinatorial PLDs. Its 5 ns speed grade supports demanding control logic, while the available 166 MHz maximum operating frequency provides a useful figure for high-speed system timing. An optional power-down input can be assigned to device pin 4; when enabled and asserted, output data and internal logic states are latched and held.
The ATF16V8C is specified for operation from 5 V, with industrial and commercial supply tolerances identified in the manufacturer documentation. The available product information identifies a commercial operating range from 0 C to 70 C and a standard-power 5 ns configuration. Its 20-pin PLCC package is suitable for legacy and industrial control systems where ceramic leaded-chip-carrier footprints and programmable logic are established requirements.
Typical uses include industrial controller address decoding, state-machine implementation, peripheral interfacing, signal qualification, and compact combinational control networks. The eight-output structure makes the device useful when a design needs several related Boolean functions without occupying a larger FPGA or microcontroller.
Designers should verify the programmed architecture, pin 4 power-down assignment, supply tolerance, and timing against the manufacturer datasheet before replacing a PAL or GAL device. PCB layouts must accommodate the PLCC-20 footprint, programming access, and the target system’s power sequencing. This page also consolidates verified pricing, source links, application guidance, and the constrained set of directly comparable drop-in devices.

典型应用
ATF16V8C-5JX 适用于 6 应用s: Industrial Controller Address Decoding, Compact State-Machine Control, Peripheral Interface Signal Qualification, Legacy PAL and GAL Migration, Data and Control Signal Routing, Low-Power Periodic Instrumentation.
Industrial Controller Address Decoding
The ATF16V8C-5JX fits compact industrial controller address-decoding and peripheral-selection logic because its 8 macrocells can provide 8 outputs, each with 8 product terms. The 5 ns propagation-delay designation supports tighter control timing than legacy 10 ns and 15 ns PAL devices, while the 5 V supply matches established industrial logic platforms. Each programmed output can implement a selected Boolean function, allowing multiple address or command conditions to be decoded without a microcontroller. Before adoption, engineers should verify the 0 C to 70 C operating range, the configured operating mode, propagation behavior for the selected path, and the PLCC-20 footprint on the target board.
推荐
Compact State-Machine Control
The ATF16V8C-5JX is suitable for small state-machine and sequencer logic where eight configurable outputs are more appropriate than a full FPGA. Its three software-configurable operating modes permit registered, combinational, and complex logic arrangements to be selected according to the design. The 5 ns timing class and 166 MHz maximum operating-frequency figure provide useful margin for clocked control paths. Because the PLD contains 8 macrocells with 8 product terms per output, the design should be checked against the exact product-term allocation required by each transition equation. Programming-file portability and pin-assignment verification are essential when replacing an older PAL or GAL implementation.
推荐
Peripheral Interface Signal Qualification
The ATF16V8C-5JX can qualify and route peripheral-control signals in legacy industrial equipment, using its 8 outputs and configurable product terms to implement handshake, interrupt-routing, and command-enable functions. Its 5 ns propagation delay is valuable where the system must combine signals and present a resolved control output within a short timing window. The optional pin-controlled power-down function can reduce supply current below 100 uA while retaining latched output and internal logic states, making it useful in periodically active equipment. Integration requires checking the programmed polarity of the power-down pin, output-state behavior during reset, and the available supply tolerance of the selected commercial or industrial speed grade.
推荐
Legacy PAL and GAL Migration
The ATF16V8C-5JX provides a migration path for equipment built around 16R8 devices and most 20-pin combinatorial PLDs because its EECMOS architecture implements a superset of the generic 16R8 arrangement. A 5 ns speed grade can improve timing margin relative to 10 ns or 15 ns legacy devices while preserving the familiar 20-pin PLCC format. Migration should not be treated as automatic: engineers must compare pin assignments, active polarity, registered versus combinable output behavior, product-term allocation, programming requirements, and timing across every signal path. A generated equivalence report and bench-level state testing are recommended before production substitution.
推荐
Data and Control Signal Routing
The ATF16V8C-5JX can implement data-routing and control-selection functions when a design requires several mutually related Boolean outputs but not the capacity of an FPGA. Its eight macrocells and eight product terms per output allow the engineer to encode routing equations while retaining nonvolatile flash-based configuration. The 5 ns speed class helps preserve timing margin in control paths, while the 166 MHz maximum operating-frequency value supports clock-related design evaluation. When the PLD sits beside higher-speed electronics, PCB signal-integrity and grounding practices remain important even though the device uses CMOS logic. Designers should also confirm that the selected programmed mode supports the intended registered outputs and that unused pins are handled according to the manufacturer guidance.
推荐
Low-Power Periodic Instrumentation
The optional pin-controlled power-down mode makes the ATF16V8C-5JX relevant to instrumentation that spends long intervals waiting for a measurement or operator action. When the function is enabled and the control input is asserted, total current falls below 100 uA, while output data and internal logic states remain latched. The device therefore combines a 5 ns operating speed with a low-power standby state instead of requiring a complete power removal. Implementers should assign pin 4 only after reviewing the configured architecture, verify that downstream loads do not prevent the intended current reduction, and account for power-up and reset behavior. The temperature grade and supply tolerance must also be checked against the instrument environment.

- Direct architectural migration path for common legacy PLDs （对比 ATF16V8C-5JC)
设计说明
Do not assume that any 20-pin PLD with equivalent logic capacity is automatically interchangeable. The ATF16V8C-5JX supports three software-configured operating modes, and pin 4 may be assigned as the power-down input. Compare the compiled fuse map, output polarity, registered-output behavior, product-term allocation, and power-down assignment against the original device before approving a substitution.
The optional power-down mode can reduce total current consumption below 100 uA while latching output data and internal logic states. Confirm that pin 4 is not required as a functional signal in the selected configuration, verify the programmed power-down polarity, and ensure downstream receivers do not impose a load that prevents the intended low-current state. The normal supply tolerance is grade-dependent: 5 V ± 10% for industrial ranges and 5 V ± 5% for commercial ranges.
Use the manufacturer PLCC-20 footprint and verify socket orientation, pin-1 marking, and component clearance on the assembly drawing. A PLCC socket may ease legacy-product maintenance but adds mechanical height and contact resistance; direct surface mounting requires a qualified footprint and assembly process. Since the complete verified pin list was not present in the supplied excerpts, engineers should use the official package drawing rather than infer pin locations from another PLD family.
The 5 ns speed class shortens the timing margin available in fast control loops, even though the ATF16V8C is a relatively low-speed CMOS PLD. Route clock, output-enable, and critical state-transition signals away from noisy switching nodes, provide a low-impedance return path, and keep the device close to a stable supply reference. Validate setup and hold timing in the configured operating mode rather than relying only on the 5 ns headline delay.
