Product details
Overview
ATF16LV8C-10SC from Atmel is a reprogrammable EECMOS PLD with 8 macrocells, 10 ns maximum pin-to-pin delay, 3.0–5.5 V operation, and pin-controlled power-down mode (≤5 µA). It emulates 20-pin PAL architectures and serves as logic replacement in industrial control I/O expansion, legacy system upgrades, and embedded state machine implementations.
For engineers reviewing the ATF16LV8C-10SC datasheet, ATF16LV8C-10SC pinout, ATF16LV8C-10SC application, or ATF16LV8C-10SC equivalent, key selection factors include its 10 ns speed grade, 5 µA power-down current, Flash-based reprogrammability, 20-pin SOIC package, and compatibility with 16R8-family logic replacements.
Technical Context
The ATF16LV8C-10SC implements a generic PAL architecture with eight product-term-based macrocells, each supporting combinatorial or registered output modes. Its Flash-based configuration enables in-system reprogramming without UV erasure or external programming voltage.
It features automatic software-configured operation modes (combinatorial, registered, mixed), pin-keeper circuits eliminating external pull-ups, and a dedicated PD pin (Pin 4) enabling sub-5 µA standby when asserted high - with full functional retention upon wake-up.

| 9 (I9/OE) | Input / Output Enable | Configurable as general input or global OE signal controlling all I/O pins' tristate behavior |
| 10 (GND) | Ground | Primary reference for all digital and power domains |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF16LV8C-10SI | Same electrical specs and logic architecture, but rated for -40°C to +85°C industrial temperature range | Required for outdoor or factory-floor deployments where ambient exceeds 70°C | Select ATF16LV8C-10SI when operating outside commercial temperature limits; otherwise ATF16LV8C-10SC suffices |
| ATF16LV8C-10SU | Identical SOIC package and speed grade, but Pb/Halide-free/RoHS-compliant green packaging | Mandatory for EU/China export or medical-grade assemblies requiring halogen-free materials | Choose ATF16LV8C-10SU to meet RoHS 2011/65/EU and China RoHS II requirements without logic or timing trade-offs |
Compared with ATF16LV8C-10SI and ATF16LV8C-10SU, the ATF16LV8C-10SC offers identical logic performance and pinout in the commercial temperature range (0°C to 70°C), with non-green packaging - making it optimal for cost-sensitive, indoor, non-regulated industrial applications where extended temperature or environmental compliance is unnecessary.

FAQ
What is the maximum operating frequency supported by the ATF16LV8C-10SC?
The ATF16LV8C-10SC supports up to 71.4 MHz in external feedback configurations (1/(tS + tCO)), 83.3 MHz with internal feedback, and 83.3 MHz in no-feedback mode. These values derive directly from its 7 ns setup time (tS) and 7 ns clock-to-output delay (tCO) at the -10 speed grade, verified under 3.0–5.5 V supply and commercial temperature conditions.
Does the ATF16LV8C-10SC require an external programmer for configuration?
No - the ATF16LV8C-10SC uses on-chip Flash technology and supports in-system programming via standard JTAG or parallel interfaces. No external UV eraser or high-voltage programmer is needed; configuration can be updated in situ using Atmel's official development tools and compatible third-party programmers.
Can the ATF16LV8C-10SC operate reliably at 3.3 V supply voltage?
Yes - the ATF16LV8C-10SC is fully specified for 3.0 V to 5.5 V operation. At 3.3 V, it maintains its 10 ns pin-to-pin delay, 5 µA power-down current, and full I/O drive strength (8 mA sink, 4 mA source), as confirmed in DC and AC characterization tables across commercial temperature range.
Is the ATF16LV8C-10SC pin-compatible with older PAL devices like the 16R8?
Yes - the ATF16LV8C-10SC is architecturally and physically compatible with the 16R8 family and most 20-pin combinatorial PLDs. Its pinout matches standard 20-pin DIP/SOIC packages, and its logic emulation mode allows direct replacement without PCB modification, as documented in Atmel's application notes and ordering information table.
What happens to the outputs of the ATF16LV8C-10SC during power-up?
During power-up, the ATF16LV8C-10SC performs an internal asynchronous reset that drives all registered outputs low, resulting in high-impedance or high-level outputs depending on polarity configuration. This power-up reset occurs at ~2.5–3.0 V (VRST) and completes within 600–1000 ns (TPR), ensuring deterministic initialization for state machines and control logic.
