ATF16LV8C-15JI - 16V8 EE PLD, 15ns, 20-PLCC | Microchip
MPN: ATF16LV8C-15JI ✗ End of LifeATF16LV8C-15JI Overview
An EE PLD is a semiconductor logic device whose internal interconnection and Boolean functions are established by programming rather than by permanently wiring individual gates. The 16V8 designation identifies a device with eight outputs, and each output is allocated eight product terms. The three operating modes described for the ATF16LV8C family are selected automatically by software, enabling complex combinational and registered logic functions without the component count of a conventional gate-array design.
The ATF16LV8C-15JI combines a 3 V to 5.5 V operating input range with a 15 ns speed grade. The ATF16LV8C family also supports speeds down to 10 ns and includes a pin-controlled power-down option with approximately 5 uA current consumption. These features make the device useful for industrial control, interface translation, legacy peripheral support, and small embedded systems where a programmable logic block is preferable to a fixed gate network.
Its electrically erasable flash-memory implementation provides a practical balance between field programmability, deterministic logic behavior, and compact package size. The device is categorized as an EE PLD and is positioned between simple fixed gate logic and more complex programmable logic devices. Unlike a mask-programmed device, the ATF16LV8C-15JI can be configured for multiple logic functions during development, production, or field upgrades, subject to the programming and electrical requirements in the manufacturer datasheet.
Typical uses include address decoding, control-signal generation, data-routing logic, state-machine implementation, and replacement of older 20-pin PAL-style or combinatorial PLD circuits. The 8-macrocell architecture is especially suitable for small control blocks where a full FPGA or microcontroller would add unnecessary complexity. The 20-PLCC package allows the part to be used where leaded logic packages are preferred for hand soldering, prototyping, repair, or legacy board assembly.
For new PCB designs, verify the exact pin assignment, programming algorithm, timing limits, power-up behavior, and unused-pin treatment in the manufacturer datasheet. A PLCC footprint should also be checked for orientation, pad dimensions, and thermal requirements. When replacing an existing device, use the suffix and package carefully because speed grade, temperature grade, and packing code affect fit, qualification, and procurement.

Typical Applications
ATF16LV8C-15JI is suitable for 6 applications: Industrial Control and Automation Logic, Legacy Interface and Address Decoding, Data Routing and Signal Conditioning, Embedded Peripheral Control, Test and Measurement Equipment, Lighting and Display Control Logic.
Industrial Control and Automation Logic
The ATF16LV8C-15JI fits compact control blocks that require programmable Boolean logic rather than a full microcontroller. Its 8 macrocells and 8 product terms per output can implement interlock conditions, mode-control signals, alarm logic, and state transitions. The 3 V to 5.5 V operating range supports common industrial logic levels, while the 15 ns speed grade provides a defined timing class for legacy control boards. Use it when the design is a maintenance replacement or a small standalone controller whose logic must be reprogrammed during commissioning.
Recommended
Legacy Interface and Address Decoding
The ATF16LV8C-15JI can implement address decoding, chip-select generation, peripheral routing, and mixed-polarity control logic in older equipment. The family architecture is a superset of the generic 16R8 arrangement and most 20-pin combinatorial PLDs, making it useful when an existing board uses more than one logic function in a single package. Eight macrocells support several independent outputs, while automatic selection among three operating modes simplifies migration from simple combinational designs to configurations requiring registered behavior.
Recommended
Data Routing and Signal Conditioning
The ATF16LV8C-15JI is suitable for small data-routing and signal-conditioning networks where Boolean selection, gating, and format conversion are required. Its EECMOS electrically erasable flash-memory architecture allows configuration changes without a mask set, reducing development iterations compared with fixed combinational logic. The 15 ns speed rating is relevant when signals cross multiple logic levels or interface boundaries, although exact timing closure still depends on the programmed equations and the individual datasheet timing limits.
Recommended
Embedded Peripheral Control
In legacy embedded systems, the ATF16LV8C-15JI can generate peripheral enables, latch control signals, interrupt qualifiers, and protocol-related outputs around a microcontroller or processor. Its 8-macrocell capacity is sufficient for several small control functions without duplicating discrete gate packages. A key engineering consideration is preserving the original active-high or active-low output polarity during programming. For new mixed-signal systems, compare this PLD with a microcontroller when the control logic is likely to expand beyond the fixed 16V8 resource.
Recommended
Test and Measurement Equipment
The ATF16LV8C-15JI can implement control sequencing, mode selection, measurement-path routing, and front-panel logic in compact test equipment. Its electrically erasable configuration is valuable for product-family variants because multiple logic personalities can be supported without separate fixed-logic devices. The 3 V to 5.5 V range allows integration with conventional TTL or CMOS-compatible test boards, while the 15 ns speed grade helps preserve timing margins in control paths. Verify analog-interface isolation and unused-pin requirements separately from the digital logic function.
Recommended
Lighting and Display Control Logic
The ATF16LV8C-15JI can combine display-enable, lamp-control, blanking, and panel-sequencing functions in legacy lighting and display modules. Eight independently programmable outputs provide enough capacity for compact state machines and mutually exclusive mode logic without increasing the package count. The electrically erasable architecture allows firmware-independent configuration changes during product development or refurbishment. Choose it when the control pattern is stable and the design benefits from PLD replacement; use a microcontroller when dynamic lighting patterns or serial control are major requirements.

Key Differentiators
- Matches the documented 15 ns 16V8 legacy replacement class (vs ATF16LV8C-10JI)
- Retains the same 8-macrocell PLD architecture for direct logic-function migration (vs ATF16V8B-15JI)
- Supports compact 8-output programmable logic in the established 20-pin PLCC format (vs ATF16LV8C-15JC)
Design Notes
Do not treat every 16V8 PLD as electrically and logically interchangeable. Compare the ATF16LV8C-15JI with a candidate using the full ordering suffix, PLCC pinout, supply range, speed grade, temperature grade, output polarity, and programming architecture. In particular, the verified comparison material identifies obsolete ATF16LV8C and ATF16V8B variants, so a replacement should be validated against the manufacturer datasheet and the programmed equations used by the original equipment.
Decouple the supply pins at the device rather than relying on a distant bulk capacitor. Place the local ceramic bypass capacitor and any required bulk capacitance close to the PLCC power and ground terminals, and keep return current paths short. The ATF16LV8C family supports a pin-controlled power-down mode at approximately 5 uA, but normal operating current, input thresholds, and supply sequencing requirements must be taken from the exact manufacturer datasheet before power-state logic is designed.
Use a qualified 20-pin PLCC footprint and confirm pad geometry against the 9 x 9 mm package drawing. The PLCC format is leaded, but the device is assembled as a surface-mount component, so stencil design, solder-paste volume, placement orientation, and reflow profile all affect joint reliability. For repair-heavy legacy equipment, inspect socketed pins for oxidation, bent leads, and socket wear before attributing a failure to the PLD.
Analyze every configured output path against the 15 ns speed grade, including external load capacitance, fan-out, rise time, and any connector or long trace. The PLD can consolidate several formerly discrete logic functions, but consolidating functions can also concentrate timing and current demand on a single package. Preserve the original registered or combinatorial mode, output polarity, and pin assignment when migrating a programmed design to a replacement.
Compliance Information
No definitive RoHS, REACH, lead-free, halogen-free, or conflict-minerals declaration was identified for the exact ATF16LV8C-15JI ordering code.
