ATF16LV8C-10JU

Overview

The ATF16LV8C-10JU is an Electrically Erasable CMOS Programmable Logic Device (EEPLD) manufactured by Microchip Technology. It features a high-performance architecture with a maximum pin-to-pin propagation delay of 10 ns and operates within a supply voltage range of 3.0V to 5.5V. The device contains eight macrocells, each allocated eight product terms, supporting complex logic functions. It includes a programmable power-down mode option that reduces supply current to less than 5 µA when activated. The component utilizes advanced Flash technology for reprogrammability and offers 2,000V ESD protection.

Feature Summary

• Maximum 10 ns pin-to-pin delay with 7 ns setup time and 7 ns clock-to-output delay
• Ultra-low power consumption with typical 100 nA standby current and <5 µA in power-down mode
• CMOS and TTL compatible inputs/outputs with I/O pin-keeper circuits
• Industrial temperature range operation from -40°C to +85°C

Applications

• Direct replacement for 16R8 family and most 20-pin combinatorial PLDs
• State machine initialization requiring power-up reset functionality
• Logic design utilizing industry-standard 20-pin PAL architectures

Procurement Notes

Verify the ordering suffix 'U' indicates Green Package options which are Pb/Halide-free and RoHS compliant. Confirm the package type corresponds to the 'J' suffix, representing a 20-lead Plastic J-leaded Chip Carrier (PLCC). Ensure the speed grade matches the -10 designation for 10 ns performance. Check for industrial temperature rating (-40°C to +85°C) compatibility with system requirements.

Selection Notes

Select this component for applications requiring low power consumption and high-speed logic processing within a 20-pin footprint. The ATF16LV8C-10JU is suitable where industrial temperature stability is required. Consider the 8 macrocell capacity for logic complexity. Verify interface compatibility with 3.0V to 5.5V systems. Evaluate if the specific PLCC package fits the PCB layout constraints.

Part Context

The ATF16LV8C series belongs to the EEPLD category, utilizing electrically-erasable Flash memory technology. This specific part number represents the industrial temperature variant with 10 ns speed grade in a PLCC package. It is part of a broader family including commercial variants and different speed grades like the -15 model. The device supersedes older PAL technologies while maintaining pin compatibility.

FAQ

What is the function of Pin 4?

Pin 4 can be configured as a programmable power-down control pin. When configured as such, setting the pin high drops supply current to less than 5 µA. If power-down is not needed, it functions as a logic input.

How does the power-up reset feature work?

Registers reset to the low state during power-up when VCC crosses the reset voltage (VRST). This ensures registered outputs are high on power-up, aiding state machine initialization, provided VCC rise is monotonic and clock signals remain stable.

What is the maximum operating frequency?

The maximum operating frequency depends on the feedback configuration. For no feedback, it is 83.3 MHz. With internal feedback, it is 50 MHz, and with external feedback, it is 45.5 MHz.
