ATF16V8CZ-15PC - 15ns 5V EECMOS SPLD | Microchip Technology
MPN： ATF16V8CZ-15PC ✓ 啟用中ATF16V8CZ-15PC 概覽
An SPLD is a simple programmable logic device: a single monolithic IC containing AND/OR-style logic structures that are configured by the user for a specific combinational or registered logic function. In the broader semiconductor hierarchy, the ATF16V8CZ-15PC belongs to the programmable-logic family, combines PLD and FPGA attributes in function, and provides a compact alternative to a discrete gate array. Its 8 macrocells can implement multiple logic terms in one package, reducing board area and external component count.
Key features include 250 gates of logic capacity, electrically erasable Flash configuration memory, zero-power operation for the ATF16V8CZ family, 8 configurable I/O outputs, and a maximum of 16 input paths. The -15 suffix identifies a 15 ns device grade, and the -PC suffix identifies the commercial-temperature 20-pin PDIP configuration. A 5 microampere typical edge-sensing power-down mode and 25 microampere standby current support low-power system designs.
The ATF16V8CZ architecture consolidates several older 20-pin PAL device patterns and supports programmed operating modes selected automatically by development software. The device is suited to glue logic, control decoding, interface adaptation, and legacy product revisions where a compact, reprogrammable fixed-function alternative is preferable to maintaining a full FPGA or microcontroller. Its 20-pin through-hole package also simplifies inspection, prototyping, and hand rework.
Typical uses include industrial control interfaces, legacy peripheral adaptation, address decoding, alarm and interlock logic, and compact control subsystems. The electrically erasable architecture is especially useful during development because logic changes do not require new devices or socketed parts. A 5 V supply and 15 ns timing class fit systems that use legacy control buses rather than high-speed modern processor interfaces.
When laying out a board, keep the 5 V supply rail and ground return planes low impedance, and route the 20-pin PDIP footprint for straightforward through-hole assembly. Program the device with the manufacturer's logic-development software and verify unused macrocell configurations to prevent outputs from floating. Confirm the commercial operating temperature range against the system enclosure temperature before releasing the production design.
This page combines the manufacturer device description with distributor package and speed-grade data, practical PLD design guidance, and a pin-compatible comparison covering three same-footprint alternatives. It also identifies package and electrical details that engineers should confirm against the manufacturer datasheet before schematic release or production procurement.

典型應用
ATF16V8CZ-15PC 適用於 6 應用s: Industrial Control Glue Logic, Legacy Peripheral Interface Adaptation, Address and Command Decoding, Alarm and Interlock Logic, Programmable Test and Measurement Fixtures, Product Line Revisions and Legacy Retrofits.
Industrial Control Glue Logic
The ATF16V8CZ-15PC fits legacy industrial control boards that require compact combinational decoding between sensors, relays, and actuators. Its 250-gate capacity, 8 macrocells, up to 16 inputs, and 8 I/O outputs allow several interlock or decoding functions to be consolidated in one 20-pin PDIP package. The 15 ns speed grade and 12 ns maximum pin-to-pin delay suit moderate-speed control paths rather than high-bandwidth processor interfaces. Electrically erasable Flash configuration also allows firmware-style logic revisions during equipment maintenance without replacing the device.
Legacy Peripheral Interface Adaptation
The ATF16V8CZ-15PC is useful when a newer controller must communicate with older 5 V peripheral logic through handshake, chip-select, or signal-level translation functions. Its CMOS- and TTL-compatible inputs and outputs support mixed legacy environments, while 8 configurable I/O channels provide enough flexibility for bidirectional control signals. The 20-pin PDIP footprint simplifies retrofit work on older boards that use through-hole sockets. Confirm input thresholds, output drive capability, and timing against the connected peripheral before treating the PLD as a complete interface translator.
Address and Command Decoding
Address decoding is a strong application for the ATF16V8CZ-15PC because up to 16 inputs can feed programmable product terms across 8 macrocells. The device can generate chip-select or enable strobes for discrete memories, counters, and peripherals while consuming less board area than a bank of gates. Its 12 ns maximum pin-to-pin delay provides predictable combinational behavior, and electrically erasable configuration makes it practical to revise decode maps during board bring-up. Designers should still include external decode signals in the timing analysis and observe setup and hold requirements at the decoded loads.
Alarm and Interlock Logic
The ATF16V8CZ-15PC can implement compact alarm, inhibit, and safety-interlock functions where several discrete inputs must be combined before driving status outputs. Its 8 macrocells and 8 I/O outputs are appropriate for moderate channel counts, and the zero-power feature supports equipment that must retain configuration in a low-activity state. The 5 microampere typical edge-sensing power-down mode and 25 microampere typical standby current can reduce quiescent demand in monitoring subsystems. For safety-related equipment, review the applicable machine-safety requirements separately; PLD programming alone is not a functional-safety certification.
Programmable Test and Measurement Fixtures
The ATF16V8CZ-15PC is a practical choice for board test fixtures, interface conditioners, and legacy measurement adapters that need reconfigurable routing or stimulus control. Electrically erasable Flash allows a fixture to hold different logic configurations for several boards, reducing spare-part complexity. With 16 inputs, 8 I/O outputs, and 12 ns maximum pin-to-pin delay, the device handles low- and medium-speed control sequencing. The 20-pin PDIP package is easy to socket and replace in fixture hardware, although its 5 V supply requirement should be checked against modern low-voltage test equipment.
Product Line Revisions and Legacy Retrofits
The ATF16V8CZ-15PC supports cost-effective product-line revisions in which established 20-pin PLD boards require updated decoding or control behavior. Its reprogrammable configuration eliminates the need to relayout a board solely to change a logic equation, while the 250-gate capacity and 8 macrocells cover many legacy PAL patterns. Through-hole construction also eases inspection and rework in long-life equipment. For a replacement decision, verify the original part's pinout, macrocell organization, timing, and programming method rather than relying on the 16V8 family name alone.

設計說明
Do not treat every 16V8-family PLD as electrically or logically interchangeable. The ATF16V8CZ-15PC uses the ATF16V8CZ architecture and electrically erasable Flash configuration, while ATF16V8B and ATF16V8BQL devices have different organization and operating characteristics. Before replacing a part, compare the manufacturer pin-description table, macrocell map, AC timing, supply current, programming procedure, and configuration-file format. A shared 20-pin PDIP outline establishes mechanical compatibility, not functional equivalence.
The ATF16V8CZ-15PC operates from 5 V and specifies a 25 microampere typical standby current plus a 5 microampere typical edge-sensing power-down mode. In a low-power design, include the current drawn by every configured output and by the external 5 V regulator. Use the manufacturer's recommended supply bypass capacitors and place them close to the device's power and ground pins. Decoupling values should follow the ATF16V8CZ datasheet rather than a generic ceramic-capacitor rule.
The 20-pin PDIP footprint is straightforward to route, but signal integrity still depends on the rest of the board. Keep the 5 V supply trace short, provide a low-impedance ground return, and avoid routing high-current actuator or relay paths alongside the PLD's input and clock nets. For legacy systems with long interconnect traces, include propagation delay and input rise/fall time in the timing budget. Use the manufacturer package drawing for the final land pattern and drill dimensions.
Program unused macrocell outputs into defined states rather than allowing them to float, and verify that every configuration pin is handled by the programmer and board design. Because the ATF16V8CZ supports programmed operating modes selected automatically by software, a mismatched or outdated programming file can produce valid-looking but incorrect logic. Archive the exact JEDEC or programmer output with the hardware revision, then perform a power-up state test on the assembled board.
合規資訊
The ATF16V8CZ-15PC is identified as a commercial-temperature logic device, but no RoHS, REACH, lead-free, halogen-free, or conflict-minerals status is stated for this exact orderable part.
