ATF16LV8C-15SI

Overview

The ATF16LV8C-15SI is a high-performance Electrically Erasable CMOS Programmable Logic Device (EE PLD) manufactured by Microchip Technology. It utilizes Flash memory technology to provide reprogrammable logic with industry-standard pinouts compatible with many 20-pin PALs. The device features eight macrocells, each allocated eight product terms, supporting complex combinatorial and registered logic functions. Key electrical specifications include a maximum pin-to-pin propagation delay of 15 ns, an operating voltage range of 3.0V to 5.5V, and a typical standby current of 100 nA. It operates within the industrial temperature range of -40°C to +85°C.

Feature Summary

• High-speed performance with a maximum 15 ns pin-to-pin delay.
• Ultra-low power consumption featuring a programmable power-down mode reducing supply current to less than 5 µA.
• CMOS and TTL compatible inputs and outputs with I/O pin-keeper circuits eliminating internal pull-up resistors.
• Advanced Flash technology ensuring 100% testing, 20-year data retention, and 100 erase/write cycles.

Applications

• Direct replacement for legacy 20-pin PALs and 16R8 family devices.
• Complex combinatorial and registered logic function implementation.
• State machine initialization requiring power-up reset capabilities.
• Low-power embedded systems utilizing pin-controlled power-down modes.

Procurement Notes

Verify that the specific ordering code matches the required speed grade (-15) and package type (SOIC). Confirm the suffix indicates the Industrial temperature range (-40°C to +85°C). Ensure compatibility with existing design tools supporting the ATF16LV8C architecture before procurement.

Selection Notes

Select the ATF16LV8C-15SI when a 15 ns maximum delay is sufficient for the application timing requirements. Choose this part over the -10 variant if cost or availability favors the slower speed grade while maintaining the SOIC surface-mount package. Verify that the 3.0V to 5.5V supply range aligns with the system power rails.

Part Context

This component belongs to the ATF16LV8C series of EE PLDs, which emulate standard 20-pin PAL architectures. The 'SI' suffix specifically denotes the 15 ns speed grade packaged in a 20-lead Plastic Gull-wing Small Outline (SOIC) format, intended for industrial temperature applications.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the source material. Designers should verify architectural compatibility with other 20-pin PAL emulators if direct substitution is required.
