ATF16V8CZ-15SC - 15ns 8-Macrocell EEPLD | Microchip
N.º da peça: ATF16V8CZ-15SC ✓ AtivoATF16V8CZ-15SC Visão geral
An EEPLD is an electrically erasable programmable logic device: a user-programmed logic IC that stores a Boolean function in nonvolatile internal memory. It belongs to the programmable-logic hierarchy, where a PLD sits above individual gate arrays and provides a compact implementation of multiple sum-of-products logic functions. The ATF16V8CZ architecture emulates many 20-pin PAL devices and most 20-pin combinatorial PLDs, simplifying migration from older fixed-logic designs.
The ATF16V8CZ uses eight output macrocells, with each output allocated eight product terms. Its architecture supports up to 16 inputs and eight I/O outputs, while its CMOS-compatible inputs and outputs allow operation with both CMOS and TTL logic families. Low-power operation is reinforced by a 25 µA standby-current specification and the family’s zero-power designation, which is useful in systems where inactive logic should not create unnecessary static demand.
Three operating modes are selected automatically by the programming software, allowing the same device architecture to implement registered, combinatorial, and complex logic functions. The ATF16V8CZ architecture incorporates a superset of the generic 16R8 architecture and supports direct replacement of the 16R8 family and most 20-pin combinatorial PLDs. This broad compatibility makes it useful for consolidating several small PAL implementations into one device.
Typical uses include industrial automation, consumer-equipment control, interface decoding, state-machine implementation, address decoding, and compact automotive control logic. The 15 ns device grade is particularly relevant when the logic path must operate close to the system clock while retaining the simple programming workflow associated with classic GAL16V8 and PAL-compatible devices.
Designers should assign each macrocell using the manufacturer’s software and verify the resulting pin assignments against the device programming file. The 20-SOIC package requires adequate board spacing, and unused inputs should be handled according to the datasheet’s stated input rules. The commercial-temperature ordering code should also be checked against the enclosure and system-temperature requirements before deployment.

Aplicações típicas
ATF16V8CZ-15SC é adequado para 6 aplicaçãos: Industrial Automation Control Logic, Address Decoding and Memory Control, Automotive Interface Logic, Consumer Equipment Control, State Machine and Protocol Assistance, Legacy PAL Consolidation.
Industrial Automation Control Logic
The ATF16V8CZ-15SC fits compact industrial control blocks that decode commands, enforce operating interlocks, or generate machine-control sequencing signals. Its 250-gate architecture and 8 macrocells allow multiple Boolean functions to be consolidated, while the 15 ns speed grade supports paths positioned near common industrial control-clock rates. According to the ATF16V8CZ manufacturer datasheet, the device supports up to 16 inputs, 8 I/O outputs, and CMOS- and TTL-compatible signals. Confirm that the SC ordering code meets the equipment’s ambient-temperature and qualification requirements.
Recomendado
Address Decoding and Memory Control
The ATF16V8CZ-15SC can implement address decode, chip-select generation, and qualification logic in systems that do not require a larger programmable-logic device. Up to 16 inputs support address and control decoding, while the eight configurable output macrocells can produce discrete control decisions. Its 15 ns propagation-delay grade provides useful timing margin for moderate-speed buses, and the 20-SOIC package simplifies assembly compared with larger PLDs. Validate the programmed equations, pin assignments, and setup and hold timing against the target memory interface before fabrication.
Recomendado
Automotive Interface Logic
The ATF16V8CZ-15SC is suitable for small automotive or mobile equipment logic blocks where compact decoding, latch, and control functions are required. The device combines up to 16 inputs with 8 I/O outputs in eight macrocells, allowing designers to replace several separate gate packages. According to the ATF16V8CZ manufacturer datasheet, the 15 ns grade supports higher-speed control paths, and 25 µA standby current is useful for low-power operating states. Validate automotive temperature, quality, and qualification requirements before using the commercial SC ordering code.
Recomendado
Consumer Equipment Control
The ATF16V8CZ-15SC can consolidate front-panel sequencing, mode control, indicator logic, and peripheral qualification in compact consumer equipment. Its 8 macrocells and eight I/O outputs provide enough flexibility for multiple Boolean subfunctions without using a larger programmable-logic package. The 15 ns device grade helps preserve margin in moderately timed control paths, while CMOS-compatible interfacing supports modern digital subsystems. The manufacturer datasheet also states that the architecture can emulate many 20-pin PAL devices, which can assist targeted migration from older designs.
Recomendado
State Machine and Protocol Assistance
The ATF16V8CZ-15SC is appropriate for auxiliary state machines, command sequencers, and protocol-handling logic when the design can be expressed as a sum of products. Eight macrocells with eight product terms per output provide predictable logic capacity, while three software-selected operating modes help implement combinatorial and registered functions. Its 15 ns speed grade reduces propagation delay relative to the 20 ns family option, making it preferable for clocked control paths that cannot tolerate additional delay. Program and simulate the complete design to verify illegal-state behavior.
Recomendado
Legacy PAL Consolidation
The ATF16V8CZ-15SC is useful when modernizing a PCB containing several 20-pin PAL or combinatorial PLD devices. According to the ATF16V8CZ manufacturer datasheet, the architecture incorporates a superset of the generic 16R8 family and can directly replace the 16R8 family and most 20-pin combinatorial PLDs. Eight macrocells and eight product terms per output allow logic to be consolidated, but each replacement still requires a careful comparison of pin polarity, registered outputs, feedback paths, and programming-file compatibility before PCB reuse is approved.

Notas de projeto
Treat the ATF16V8CZ-15SC as a 20-SOIC footprint and preserve the land pattern defined for the exact package drawing. Keep the device away from long, high-current switching paths and place its bypass capacitors near the supply terminals when the reference design specifies them. Because this PLD can be sensitive to board-level noise and timing margins, route clock and control signals away from switching-node copper and avoid unnecessary stubs on sensitive inputs.
Do not substitute the family name ATF16V8CZ for the complete ATF16V8CZ-15SC ordering code. The speed suffix, package suffix, and temperature suffix can change the delivered grade even when the PCB footprint remains 20-SOIC. During a replacement review, compare supply voltage, macrocell architecture, propagation-delay grade, pin assignments, output polarity, registered versus combinatorial behavior, operating-temperature requirements, and programming-file compatibility.
Assign the clock and output-enable functions in the design tool and confirm the resulting pin configuration against the physical board before programming production devices. A valid Boolean design can still fail in hardware if its pin assignments or feedback paths are incorrect. Simulate normal transitions, illegal states, and reset behavior, and confirm timing against the 15 ns device grade and the interface timing requirements of the surrounding logic.
The ATF16V8CZ-15SC operates from 5 V and can interface with CMOS and TTL-compatible logic. Follow the manufacturer’s supply recommendations and ensure that the 5 V rail remains within the device’s permitted operating limits under every transient condition. If the PLD sits near a switching regulator, follow the reference-layout recommendations for bypass placement and grounding to prevent supply noise from changing macrocell behavior or affecting timing margin.
