ATF16V8C-7JC

Overview

The ATF16V8C-7JC is a high-performance Electrically Erasable CMOS Programmable Logic Device (EE PLD) manufactured by Microchip Technology. It utilizes Atmel Flash memory technology to provide reprogrammability with 100 erase/write cycles and 20-year data retention. The device features a maximum pin-to-pin propagation delay of 7.5 ns and operates within a commercial temperature range of 0°C to +70°C. It supports a 5V ± 5% power supply and includes an optional pin-controlled power-down mode that reduces current consumption to less than 100μA. The component is housed in a 20-lead Plastic J-leaded Chip Carrier (PLCC) package.

Feature Summary

• Industry-standard architecture emulating many 20-pin PALs
• 7.5 ns maximum pin-to-pin delay for high-speed logic applications
• Advanced Flash technology enabling reprogramming and 20-year data retention
• Pin-controlled power-down mode reducing supply current to under 100μA

Applications

• Direct replacement for 16R8 family and most 20-pin combinatorial PLDs
• Complex logic function realization using configurable macrocells
• System power reduction through low-power standby modes
• PCI compliant digital logic interfacing

Procurement Notes

Verify the specific ordering code ATF16V8C-7JC against the manufacturer's official documentation to confirm package type and speed grade. Ensure compatibility with existing JEDEC fuse files if replacing standard 16V8 devices without power-down features. Confirm RoHS compliance status based on the manufacturing date and suffix requirements.

Selection Notes

Select this component when a 7.5 ns delay is required for commercial temperature environments. The PLCC package is suitable for through-hole mounting. Consider the power-down feature availability; if not needed, Pin 4 functions as a standard logic input. Ensure programming tools support the extended 16V8CEXT fuse file format if utilizing the power-down option.

Part Context

This part belongs to the ATF16V8C series of high-performance EE PLDs. It offers a superset of generic architectures, allowing it to emulate various 20-pin PAL devices across registered, complex, and simple modes. The 'C' designation indicates commercial temperature range operation, while 'J' specifies the PLCC package.

Replacement Considerations

ATF16V8C-7JU serves as an industrial temperature variant (-40°C to +85°C) with identical electrical characteristics.
