ATF16V8C-7SU - 7ns 16V8 EECMOS PLD | Microchip Technology
부품 번호: ATF16V8C-7SU ✓ 활성ATF16V8C-7SU 개요
A programmable logic device, or PLD, is a semiconductor whose internal digital logic is configured for a specific function. The ATF16V8C belongs to the SPLD family, which sits between fixed logic gates and larger FPGAs. Its 16V8 architecture provides a practical way to consolidate multiple gates and combinatorial functions into one reprogrammable component, reducing board area while retaining reusable configuration memory.
The ATF16V8C uses Atmel's EECMOS process and electrically erasable Flash technology for nonvolatile, in-circuit reprogramming. According to the manufacturer datasheet, each of the eight outputs is allocated eight product terms. The architecture supports automatic configuration into three operating modes, allowing more complex logic functions than a basic fixed AND-OR array.
The ATF16V8C family supports speed grades down to 5 ns, while the ATF16V8C-7SU is identified as a 7 ns industrial-temperature, green-rated variant in the supplied distributor data. An optional pin-controlled power-down function can reduce supply current to less than 100 microamperes. The device also includes pin-keeper circuitry, helping preserve input states when the input buffer is disabled.
Typical uses include industrial control logic, interface decoding, state-machine implementation, peripheral glue logic, and compact embedded-control subsystems. Because the ATF16V8C architecture is described as a superset of generic 16R8 and many 20-pin combinatorial PLD architectures, it can simplify logic consolidation when board space and component count are important.
Designers should verify the configured fuse map, pin assignments, and power-down use of pin 4 before release. When power-down is enabled, output data and internal logic states are latched and held; otherwise pin 4 may serve as a logic input. This page combines verified manufacturer and distributor data with practical selection guidance, comparison information, and design notes.

일반적인 애플리케이션
ATF16V8C-7SU 적합 용도: 6 애플리케이션s: Industrial Control Logic, Interface Decoding, Embedded State Machines, Battery-Powered Instrumentation, Peripheral Interface Consolidation, Communication Control Logic.
Industrial Control Logic
The ATF16V8C-7SU fits compact industrial control logic where one programmable device can replace several gate packages. Its 8 macrocells, 8 user I/Os, 300-gate equivalent density, and 7 ns target speed provide useful timing margin for combinational decoding and control functions. According to the Microchip manufacturer datasheet, each output receives 8 product terms, while automatic mode configuration supports more complex logic than a basic fixed AND-OR array. The 20-pin SOIC package simplifies assembly, but designers must verify industrial-temperature requirements, power-supply levels, and the programmed fuse map before production release.
추천
Interface Decoding
The ATF16V8C-7SU can decode address, command, or peripheral-selection signals in a small embedded subsystem. Its 16V8 architecture provides eight user I/Os and eight outputs, each with eight product terms, allowing multiple Boolean decode equations to be consolidated in one nonvolatile device. The 7 ns speed grade is especially useful when decoded outputs must meet a defined sampling interval. According to the manufacturer datasheet, the architecture is a superset of generic 16R8 and most 20-pin combinatorial PLD arrangements, which helps reduce component count, but PCB designers should preserve pin 4's selected power-down or input function and verify every output after programming.
추천
Embedded State Machines
The ATF16V8C-7SU is appropriate for small embedded state machines and sequencing functions requiring reprogrammable nonvolatile logic. Its electrically erasable Flash configuration allows logic revisions without replacing the device, while the eight macrocells provide space for registered and combinational terms. The reported 7 ns timing grade helps constrain propagation between external events and state outputs. According to the Microchip manufacturer datasheet, pin 4 can optionally trigger a low-current power-down state in which output data and internal logic states are latched and held. That feature is useful in battery-operated or intermittently powered equipment when the state machine must resume predictably.
추천
Battery-Powered Instrumentation
The optional ATF16V8C-7SU power-down function makes the device relevant to portable instrumentation and intermittently powered modules. According to the Microchip manufacturer datasheet, enabling pin 4 as a power-down control and driving it high reduces total supply current to less than 100 µA while latching outputs and internal logic states. This allows a control section to remain resident without continuously driving the rest of the system. The trade-off is reduced active-mode flexibility while power-down is asserted, so the system must define wake conditions and ensure external loads do not defeat the intended low-power state.
추천
Peripheral Interface Consolidation
The ATF16V8C-7SU can consolidate peripheral glue logic around 8 user I/Os, including command qualification, chip selection, and status decoding. Its 20-pin SOIC package offers a compact surface-mount implementation, and the electrically erasable Flash architecture supports design revisions without changing the PCB. The manufacturer describes the device as a superset of several generic 20-pin combinatorial PLD architectures, supporting migration from simpler devices. Engineers should calculate worst-case timing from the 7 ns-class specification, include setup and hold requirements at connected peripherals, and validate the final fuse map because a package-compatible replacement does not guarantee identical configuration behavior.
추천
Communication Control Logic
The ATF16V8C-7SU can implement protocol framing assistance, command filtering, and data-routing control around communication peripherals. Its 8 macrocells and 7 ns target speed support compact, deterministic combinational functions at the interface boundary. According to the Microchip manufacturer datasheet, the three automatically selected operating modes and eight product terms per output provide more implementation flexibility than a simple 16R8 arrangement. When used beside a communication controller, the PLD should be assigned only functions whose timing can be proven from the complete datasheet. The 20-SOIC footprint aids routing, while pin-controlled power-down can reduce consumption during idle periods if system timing allows outputs to remain latched.

설계 노트
If pin 4 is configured as the power-down control, the manufacturer reports total current below 100 µA while output data and internal logic states are latched. Confirm that external pull networks, input devices, and attached bus nodes do not prevent the system from reaching the intended low-current state. If power-down is unnecessary, pin 4 may be used as a logic input, but the programmed configuration and hardware net must agree.
Do not treat a same-package replacement as automatically equivalent. Verify the numbered pin assignments, supply requirements, speed grade, macrocell architecture, product-term allocation, and programmed fuse map against the manufacturer datasheet. ATF16V8B-15SU is substantially slower than the ATF16V8C-7SU, and suffix differences may encode qualification or environmental attributes. Retain the original device's timing and configuration assumptions until the replacement is validated at system level.
Keep the 20-pin SOIC footprint within the bounds of a verified 20-SOIC assembly drawing and observe the manufacturer's recommended land pattern, solder-mask, and thermal-pad guidance if any. Pin 1 identification must remain unambiguous on the PCB because reversed orientation can place a configuration or clock signal on the wrong net. Before fabrication, compare the PCB pin-1 marker and package orientation against the selected package drawing and the manufacturer's numbered pin diagram.
The advertised 7 ns speed is not a complete system timing guarantee. Evaluate propagation delay under the intended output load, include setup and hold requirements of connected devices, and account for temperature and supply variation using the datasheet timing tables. For external clocked or registered functions, verify output skew and transition behavior in the actual board environment. Simulation and bench validation should use the programmed fuse map that will be used for production.
규정 준수 정보
The verified distributor data identifies the 7SU suffix as green-rated and industrial-temperature, but it does not provide explicit RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations. The listed industry, green, and temperature descriptors must not be treated as substitutes for formal compliance evidence.
