Product details
Overview
ATF16LV8C-10XU from Atmel is a reprogrammable 20-pin electrically erasable CMOS PLD with 8 registered outputs, 10 ns maximum pin-to-pin delay, 3.0–5.5 V supply operation, and pin-controlled power-down mode drawing ≤5 µA. It directly replaces 16R8-family PALs in industrial control logic, address decoding, and bus interface glue logic.
For engineers reviewing the ATF16LV8C-10XU datasheet, ATF16LV8C-10XU pinout, ATF16LV8C-10XU application, or ATF16LV8C-10XU equivalent, this device supports industrial temperature range (−40°C to +85°C), TSSOP-20 packaging, Flash-based configuration retention, and low-power registered logic synthesis with programmable output enable and clocked feedback paths.
Technical Context
The ATF16LV8C-10XU implements a generic 8-output, 8-product-term-per-output architecture with three configurable operating modes (combinatorial, registered, mixed) determined by software programming. Its logic array feeds into D-type registers clocked by a single global CLK input, with asynchronous OE control and optional PD pin for hardware-triggered ultra-low-power state.
It uses Atmel's Flash memory technology for nonvolatile configuration storage, enabling 100% factory testing, 20-year data retention, and 100 erase/write cycles. Input pins are 5V-tolerant, I/O buffers support CMOS/TTL levels, and pin-keeper circuits eliminate external pull-ups.

Equivalent & Alternatives
The following parts are listed as comparable options for similar PLD logic applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF16LV8C-10XI | Same silicon, PDIP/SOIC packages only (20P3/20S); no TSSOP option | Limited to through-hole or standard SOIC PCB footprints; lacks 4.4 mm TSSOP form factor | Select when legacy assembly lines require 0.300" wide packages or manual soldering compatibility |
| ATF16V8B-10XU | Lower-density variant (no power-down pin, 5 µA standby not guaranteed, 100 nA typical only) | Suitable for cost-sensitive designs where active power-down control is unnecessary | Choose when ultra-low-power sleep mode is not required and B-version qualification suffices |

FAQ
What is the maximum operating frequency supported by the ATF16LV8C-10XU?
The ATF16LV8C-10XU supports up to 71.4 MHz in external feedback mode (1/(tS + tCO)), 83.3 MHz in internal feedback mode, and 83.3 MHz in no-feedback operation. These values derive from its 10 ns pin-to-pin delay, 7 ns clock-to-output, and 7 ns setup time specifications under industrial conditions. The ATF16LV8C-10XU achieves these rates while maintaining full functionality across −40°C to +85°C.
Does the ATF16LV8C-10XU require external pull-up resistors on its I/O pins?
No, the ATF16LV8C-10XU integrates pin-keeper circuits on all I/O pins, eliminating the need for external pull-up resistors and their associated power consumption and board area. This feature is confirmed in the device's DC characteristics and functional description, and applies directly to the ATF16LV8C-10XU in both active and power-down states.
Can the ATF16LV8C-10XU be used in a 3.3 V-only system with 5 V-tolerant inputs?
Yes, the ATF16LV8C-10XU operates from 3.0 V to 5.5 V and features 5 V-tolerant inputs, allowing it to accept 5 V logic signals while powered from a 3.3 V supply. This capability is explicitly specified in the "Features" and "DC Characteristics" sections and applies to the ATF16LV8C-10XU without level-shifting components.
What is the guaranteed minimum number of erase/write cycles for the ATF16LV8C-10XU?
The ATF16LV8C-10XU guarantees a minimum of 100 erase/write cycles, as stated in the "High-reliability CMOS Process" section of its datasheet. This endurance rating applies to the Flash configuration memory and is validated across the full industrial temperature range for the ATF16LV8C-10XU.
Is the ATF16LV8C-10XU RoHS-compliant and halogen-free?
Yes, the ATF16LV8C-10XU is offered in green package options that are Pb/halide-free and RoHS-compliant, as documented in the "Ordering Information" and "Green Package Options" sections.
