ATF16V8C-5XC

Overview

The ATF16V8C-5XC 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 provides eight macrocells, each with eight product terms, supporting registered, combinatorial I/O, or dedicated input configurations. It operates at a maximum pin-to-pin delay of 5 ns and supports a pin-controlled power-down mode reducing supply current to less than 100 μA. The device is housed in a 20-lead TSSOP package and complies with PCI standards.

Feature Summary

• High-speed EE PLD with 5 ns maximum pin-to-pin delay
• Eight macrocells with eight product terms per macrocell
• Pin-controlled power-down mode reduces current to <100 μA
• Internal input and I/O pin-keeper circuits eliminate floating pins

Applications

• Direct replacement for 16R8 family and most 20-pin combinatorial PLDs
• PCI compliant system logic design
• State machine initialization requiring power-up reset

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature range. The 'X' suffix indicates a lead-free, RoHS-compliant TSSOP package. Confirm availability status as older speed grades may be subject to obsolescence notices.

Selection Notes

Select this part for applications requiring direct compatibility with standard 20-pin PAL architectures. Ensure the design compiler software is configured correctly for the desired mode (registered, complex, or simple). Verify that the 5 ns speed grade meets the system timing requirements, noting that commercial devices operate within a 0°C to 70°C range.

Part Context

This component belongs to the ATF16V8C series of high-performance EECMOS programmable logic devices. The series offers various speed grades and package options, including PLCC, PDIP, SOIC, and TSSOP. The ATF16V8C-5XC specifically denotes the 5 ns speed grade in the surface-mount TSSOP package.

Replacement Considerations

The ATF16V8C-5JC is a commercial equivalent in the same package with identical electrical characteristics but potentially different manufacturing lot dates. For industrial temperature ranges (-40°C to 85°C), the ATF16V8C-7XI or ATF16V8C-7PI are recommended downgrades from the 'I' to 'C' device line.
