ATF16V8CZ-15PC

Overview

The ATF16V8CZ-15PC 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% test coverage and 2,000V ESD protection. The device features eight macrocells, each allocated eight product terms, supporting registered, complex, or simple logic configurations. It operates within a commercial temperature range of 0°C to +70°C with a maximum propagation delay of 15 ns at a supply voltage of 5V ±5%. Key electrical characteristics include a typical standby current of 5 µA and CMOS/TTL compatible inputs and outputs.

Feature Summary

• High-speed performance with a maximum pin-to-pin delay of 15 ns
• Low-power operation featuring a typical 5 µA edge-sensing power-down mode
• Reprogrammable via advanced Flash technology with 100 erase/write cycles
• CMOS and TTL compatible I/Os with internal pin-keeper circuits

Applications

• Direct replacement for 16R8 family and most 20-pin combinatorial PLDs
• Emulation of industry-standard 20-pin PAL devices
• PCI-compliant logic interface designs
• State machine initialization requiring power-up reset functionality

Procurement Notes

Verify the package type corresponds to the 'P' suffix, indicating a 20-lead Plastic Dual Inline Package (PDIP). Confirm the operating temperature range matches the application requirements, as this specific part number is designated for commercial use (0°C to +70°C). Ensure programming equipment supports the ATF16V8CZ architecture and Flash memory specifications.

Selection Notes

Select this component when a reprogrammable solution replacing legacy 20-pin PALs is required in a through-hole DIP package. Choose the -15 speed grade if a maximum propagation delay of 15 ns is acceptable. Consider the industrial variant (-15PI) if operation below 0°C is necessary. Verify that the design utilizes the available eight macrocells and does not exceed the 15 ns timing constraints under commercial temperature conditions.

Part Context

This device belongs to the ATF16V8CZ series of EEPLDs, which supersede earlier ATF16V8C models with Green (RoHS compliant) packaging options. The 'Z' suffix denotes the inclusion of lead-free and halide-free manufacturing processes. The 'PC' suffix specifically identifies the commercial temperature range and PDIP package format within the broader ATF16V8CZ product line.

Replacement Considerations

Public confirmed substitute part numbers: ATF16V8CZ-15PI (Industrial Temperature Range, same package), ATF16V8CZ-15PU (Industrial Temperature Range, Green RoHS compliant, same package). Note that standard ATF16V8C parts may require de-rating for industrial temperatures.
