ATF16V8C-7JI

Overview

The ATF16V8C-7JI is a high-performance electrically erasable CMOS programmable logic device (EE PLD) manufactured by Microchip Technology. It features an industry-standard architecture that emulates many 20-pin PALs, offering a maximum pin-to-pin delay of 7.5 ns and a clock-to-output delay of 5 ns. The device operates within the industrial temperature range of -40°C to +85°C and utilizes a 20-lead Plastic J-leaded Chip Carrier (PLCC) package. It incorporates advanced flash technology for reprogrammability, includes a pin-controlled power-down mode reducing current to under 100μA, and provides 2000V ESD protection with 20-year data retention.

Feature Summary

• High-speed performance with 7.5 ns max input-to-output delay and 166 MHz internal feedback frequency
• Industrial temperature operation (-40°C to +85°C) in a 20-lead PLCC package
• Pin-controlled power-down mode reduces supply current to less than 100μA
• Advanced EE Flash memory technology with 100 erase/write cycles and 20-year data retention

Applications

• Direct replacement for standard 20-pin combinatorial PLDs and 16R8 family devices
• Complex logic function realization using configurable macrocells
• State machine initialization utilizing power-up reset features
• Low-power system designs requiring pin-controlled sleep modes

Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified suppliers. Confirm the specific ordering code ATF16V8C-7JI matches the required industrial temperature range and PLCC package. Check for RoHS compliance status as indicated in the datasheet revision history. Ensure programming equipment supports the extended JEDEC fuse file format if power-down features are utilized.

Selection Notes

Select the ATF16V8C-7JI when industrial temperature stability (-40°C to +85°C) is required alongside a 7.5 ns propagation delay. Choose this part over commercial variants if operating conditions exceed 70°C. The PLCC package is suitable for through-hole mounting. Consider the ATF16V8C-7JC if commercial temperature range suffices, noting that industrial versions may require de-rating if used in commercial environments.

Part Context

This component belongs to the ATF16V8C series of Electrically Erasable Programmable Logic Devices. Originally developed by Atmel Corporation, the product line was acquired by Microchip Technology. The series is designed to provide a flexible, reprogrammable alternative to one-time programmable PALs, featuring universal architecture support for registered, complex, and simple logic modes.

Replacement Considerations

ATF16V8C-7JU: Identical electrical specifications and speed grade but housed in a 20-lead SOIC package instead of PLCC.

FAQ

What is the maximum operating frequency for internal feedback?

The maximum operating frequency for internal feedback is 166 MHz.

How does the power-down feature affect output states?

In power-down mode, all output data and internal logic states are latched and held. Outputs previously in a high-Z state remain high-Z.

Can the ATF16V8C-7JI emulate standard 16V8 devices?

Yes, it can emulate many 20-pin PALs including 16L8, 16H8, 16P8, and others depending on the compiler mode selected.
