ATF16V8C-7PI

Overview

The ATF16V8C-7PI is a high-performance electrically-erasable programmable logic device (EE PLD) manufactured by Microchip Technology. It utilizes EECMOS Flash memory technology and features an industry-standard architecture that emulates many 20-pin PALs. The component offers a maximum pin-to-pin propagation delay of 7 ns and supports a low-power pin-controlled power-down mode with current consumption below 100 μA. It operates within the industrial temperature range of -40°C to +85°C and is housed in a 20-lead Plastic Dual Inline Package (PDIP).

Feature Summary

• High-speed EE PLD with 7 ns maximum pin-to-pin delay.
• Pin-controlled power-down mode reduces supply current to less than 100 μA.
• CMOS and TTL compatible inputs and outputs with I/O pin keeper circuits.
• Reprogrammable via advanced Flash technology with 100 erase/write cycles.

Applications

• Direct replacement for 16R8 family and most 20-pin combinatorial PLDs.
• State machine initialization utilizing power-up reset features.
• Logic functions requiring complex, registered, or simple modes.

Procurement Notes

Verify the package type corresponds to the 'P' suffix, indicating a 20-lead PDIP. Confirm the speed grade '7' matches the required 7 ns timing specifications. Ensure the industrial temperature rating (-40°C to +85°C) aligns with system environmental requirements. Check for RoHS compliance status as per the specific manufacturing batch documentation.

Selection Notes

Select this component when replacing legacy 20-pin PAL devices with reprogrammable flexibility. The ATF16V8C-7PI is suitable for designs requiring industrial temperature stability and low standby power through the optional power-down feature. Consider the macrocell configuration options if complex logic emulation is necessary.

Part Context

This part belongs to the ATF16V8C series of Electrically Erasable Programmable Logic Devices. It is designed to provide a superset of generic architectures, allowing it to function as registered, complex, or simple logic devices depending on software configuration.
