ATF16V8BQ-10PC - 10ns 8-Macrocell EEPLD | Microchip
MPN: ATF16V8BQ-10PC ✓ Hoạt độngATF16V8BQ-10PC Tóm tắt
A PLD is a user-programmable digital logic device. Within the product hierarchy, an EEPLD is a PLD that uses electrically erasable nonvolatile memory to store its configuration. The ATF16V8B family combines the flexible logic density of an EPLD with the familiar programming environment and package options associated with 20-pin PAL devices. The Q suffix identifies the electrically erasable and erasable-programming architecture described by the manufacturer datasheet.
The principal features of the ATF16V8BQ-10PC include 8 macrocells, 250 programmable gates, a maximum 10 ns propagation delay, and operation from a nominal 5 V supply. Each macrocell can implement a substantial product-term function, allowing several related Boolean equations to share a compact package. The device is available in a through-hole PDIP package for applications where through-hole assembly, prototyping access, or generous board spacing is preferred.
Its 83 MHz CMOS implementation supports the stated 10 ns speed grade while providing eight macrocell outputs and as many as 16 input functions through the device architecture. Programmed logic remains stored in nonvolatile memory, so the configuration does not require a programmer at every power-up. This makes the device useful for control, decoding, address translation, interface adaptation, and compact sequential-logic blocks that do not justify a larger programmable logic device.
Typical uses include industrial control logic, legacy peripheral interfaces, instrumentation signal routing, test fixtures, and compact embedded control boards. The ATF16V8BQ-10PC is particularly appropriate when an existing 20-pin PAL footprint must be retained while gaining electrically erasable reprogrammability and a 10 ns speed grade.
PCB design should preserve the standard 20-pin PDIP footprint, route the clock and output-enable signals away from sensitive inputs, and connect power and ground pins according to the manufacturer pin-description table. Validate the programmed equations, timing, and unused-pin states in hardware before production release.

Ứng dụng tiêu biểu
ATF16V8BQ-10PC phù hợp cho 6 Áp dụngs: Industrial Control Logic, Legacy PAL Interface Adaptation, Instrumentation Signal Routing, Address Decoding and Control, Test Fixture Sequencing, Embedded Peripheral Control.
Industrial Control Logic
The ATF16V8BQ-10PC suits compact industrial control blocks requiring up to 16 inputs, 8 outputs, and a 10 ns propagation delay. It can consolidate Boolean interlocks, state decoding, actuator-command logic, and discrete sequencing functions within eight macrocells. Electrically erasable configuration allows logic revisions during commissioning without replacing the IC, while the 20-pin PDIP package remains convenient for through-hole industrial controller boards. Validate operating-temperature limits, noise immunity, and grounding against the production enclosure before release.
Được đề xuất
Legacy PAL Interface Adaptation
The ATF16V8BQ-10PC is appropriate for adapting a legacy 20-pin PAL-style interface when the complete function fits eight macrocells and a 10 ns speed grade. Its architecture can emulate many 20-pin combinatorial PLDs while adding electrically erasable reconfiguration. A migration can therefore preserve the familiar through-hole footprint and simplify design iterations. Before substitution, verify each pin function, feedback path, output-enable polarity, and timing relationship against the original schematic and the manufacturer datasheet.
Được đề xuất
Instrumentation Signal Routing
For instrumentation and test systems, the ATF16V8BQ-10PC can implement decoding, mode selection, range routing, and control interlocks with an 83 MHz maximum clock frequency. The 10 ns propagation delay provides margin for moderate-speed control paths, while 8 macrocells consolidate functions that otherwise require multiple gate-level devices. Its nonvolatile configuration supports repeatable setup across units and rapid engineering changes. Keep sensitive analog and measurement paths physically separate from PLD switching and clock routing.
Được đề xuất
Address Decoding and Control
The ATF16V8BQ-10PC can consolidate address decode, chip-select generation, write-enable control, and mode-command logic when those functions require no more than eight macrocells. Its 10 ns speed grade is useful for moderate-speed peripheral control, and the electrically erasable architecture permits fixes without socketed components. A practical design should account for propagation delay, output skew, and simultaneous switching. Confirm that every decoded path fits the product-term and macrocell limits in the family datasheet.
Được đề xuất
Test Fixture Sequencing
The ATF16V8BQ-10PC can coordinate fixture step sequencing, relay-control interlocks, status decoding, and measurement-path selection in a compact through-hole design. Eight macrocells and a 10 ns propagation delay are sufficient for many low-to-medium-speed digital fixture routines, and nonvolatile configuration ensures identical behavior after power cycling. Use clean grounds, short return paths, and deliberate clock routing because long fixture wiring can increase susceptibility to coupling. Validate timing margins with the longest supported cable and relay configuration.
Được đề xuất
Embedded Peripheral Control
The ATF16V8BQ-10PC can act as a glue-logic controller between an embedded processor and discrete peripherals by handling ready/valid handshakes, interrupt qualification, and peripheral selection. The 83 MHz maximum clock frequency accommodates common low-speed control interfaces, while the 10 ns speed grade supports reasonably short combinational paths. Electrically erasable programming makes the controller convenient for board bring-up and firmware-related interface revisions. Confirm setup and hold timing at the connected microcontroller and observe output-enable requirements.

Ghi chú thiết kế
Place the ATF16V8BQ-10PC at the standard 20-pin PDIP footprint with pin 1 aligned to the package marker and the PCB notch. Confirm every net against the pin-description table in the Microchip ATF16V8B family datasheet. Maintain clearances between clock and output-enable routing and any sensitive analog or low-level signal paths. For a new board, leave accessibility for programming and in-circuit configuration if the chosen toolchain requires it.
Route the 5 V supply and ground connections directly to the appropriate package pins, then place the required bypass capacitors close to the IC. Keep the current return path short and avoid sharing a narrow return segment with unrelated switching loads. Use the capacitor values and voltage ratings specified by the manufacturer, and verify power sequencing if the ATF16V8BQ-10PC shares a supply rail with slower-starting logic.
Treat CLK and OE as timing-critical nets even though the device supports an 83 MHz maximum clock frequency. Route them away from output signals that switch simultaneously, minimize stubs, and use a ground reference where practical. In legacy instrumentation or fixture systems, account for connector and cable delays in addition to the device's 10 ns propagation delay. Validate the worst-case path with the intended peripheral and external loading.
Do not assume that every 16V8-family suffix is a physical drop-in alternative. Package, speed grade, architecture, temperature grade, and programmed equations must all match the target design. In particular, PLCC and TSSOP variants cannot be installed in a 20-pin PDIP footprint without PCB changes. For the ATF16V8BQ-10PC, use the ATF16V8B family datasheet to verify unused-pin treatment, output feedback, and programming behavior before committing to production.
