ATF16V8CZ-15SC

Overview

The ATF16V8CZ-15SC is a high-performance Electrically Erasable CMOS Programmable Logic Device (EEPLD) manufactured by Microchip Technology. It utilizes Flash memory technology to provide reprogrammability with 100,000 erase/write cycles and 20-year data retention. The device features eight macrocells, each allocated eight product terms, supporting registered, complex, or simple logic configurations. It offers a maximum pin-to-pin propagation delay of 15 ns and operates within a commercial temperature range of 0°C to +70°C. The component is housed in a 20-lead Plastic Gull-wing Small Outline (SOIC) package.

Feature Summary

• High-speed performance with 15 ns maximum propagation delay
• Low-power standby mode consuming typically 5 µA
• Reprogrammable Flash architecture with 100,000 erase/write cycles
• CMOS and TTL compatible inputs and outputs with pin-keeper circuits

Applications

• Direct replacement for 16R8 family and other 20-pin combinatorial PLDs
• PCI-compliant interface logic design
• State machine initialization and control logic
• General-purpose digital logic emulation

Procurement Notes

Verify the specific ordering suffix 'SC' corresponds to the 20-lead SOIC package and commercial temperature range as defined in the manufacturer's ordering guide. Confirm RoHS compliance status if required, noting that Green package options may carry different suffixes such as 'SU'. Ensure programming equipment supports the ATF16V8CZ architecture for reliable downloading and verification.

Selection Notes

Select this component when a 15 ns speed grade is sufficient for the application timing requirements. The commercial temperature range (0°C to +70°C) limits suitability for harsh environments; industrial variants (-40°C to +85°C) are available with suffixes like 'SI' or 'XI'. Consider the SOIC package constraints regarding PCB space and soldering profiles compared to DIP or PLCC alternatives.

Part Context

This part belongs to the ATF16V8CZ series, which supersedes earlier ATF16V8C devices. The 'CZ' designation indicates the use of Atmel/Microchip's electrically erasable Flash technology, distinguishing it from OTP or EPROM-based predecessors. The series provides architectural compatibility with standard PAL devices while offering superior reprogrammability and lower power consumption.

Replacement Considerations

ATF16V8CZ-15SI serves as the industrial temperature equivalent. ATF16V8CZ-15JU and ATF16V8CZ-15PU are RoHS-compliant replacements for PLCC and PDIP packages respectively. Verify pinout compatibility when substituting with older ATF16V8C variants.
