ATF16V8CZ-15SI

Overview

The ATF16V8CZ-15SI is a high-performance Electrically Erasable CMOS Programmable Logic Device (EEPLD) manufactured by Microchip Technology. It utilizes Flash memory technology to provide reprogrammability with 100% testing and 2,000V ESD protection. The device features eight macrocells, each allocated eight product terms, supporting registered, complex, or simple logic configurations. Key electrical specifications include a maximum pin-to-pin propagation delay of 15 ns, a typical standby current of 5 µA, and operation over an industrial temperature range of -40°C to +85°C. It operates on a 5V supply with ±10% tolerance.

Feature Summary

• High-speed performance with 15 ns maximum propagation delay
• Low-power consumption featuring 5 µA typical standby current
• CMOS and TTL compatible inputs and outputs with pin-keeper circuits
• Advanced Flash technology allowing 100 erase/write cycles and 20-year data retention

Applications

• Direct replacement for 16R8 family and most 20-pin combinatorial PLDs
• PCI-compliant system logic design
• State machine initialization requiring power-up reset functionality
• Applications requiring automatic power-down in slow clock systems

Procurement Notes

Verify the package type corresponds to the 'S' suffix, indicating a 20-lead Plastic Gull-wing Small Outline (SOIC) package. Confirm the 'I' suffix matches the required Industrial temperature range (-40°C to +85°C). Ensure the speed grade '15' aligns with the 15 ns timing requirements. Check for RoHS compliance if lead-free packaging is mandated, noting that standard parts may differ from Green options.

Selection Notes

Select this component when replacing legacy PAL devices such as the GAL16V8 or 16R8 families. Choose the ATF16V8CZ-15SI specifically for designs requiring SOIC surface-mount packaging within an industrial temperature environment. Consider the 15 ns delay for applications operating up to approximately 62 MHz in no-feedback mode. Evaluate the 5 µA standby current benefit for power-sensitive asynchronous systems.

Part Context

This part belongs to the ATF16V8CZ series of EEPLDs, which supersede earlier ATF16V8C models. The 'Z' suffix typically denotes specific manufacturing revisions or environmental compliance updates introduced around 2005. It serves as a drop-in architectural replacement for various 20-pin PAL devices, offering enhanced reprogrammability via Flash memory compared to traditional EPROM-based PLDs.

Replacement Considerations

Public confirmed substitute part numbers: ATF16V8CZ-15JI (PLCC), ATF16V8CZ-15PI (PDIP), ATF16V8CZ-15XI (TSSOP).
