ATF16V8CZ-12XC

Overview

The ATF16V8CZ-12XC is a high-performance Electrically Erasable CMOS Programmable Logic Device (EEPLD) manufactured by Microchip Technology. It utilizes advanced Flash memory technology to provide reprogrammability with 100 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. Key electrical specifications include a maximum pin-to-pin propagation delay of 12 ns, a typical standby current of 5 µA, and operation over the commercial temperature range of 0°C to +70°C. It operates on a single 5V supply (±5%) and offers CMOS and TTL compatible inputs and outputs.

Feature Summary

• High-speed performance with 12 ns maximum pin-to-pin delay
• Low-power architecture featuring 5 µA typical standby current
• Advanced Flash technology enabling 100 erase/write cycles and 20-year data retention
• Universal architecture emulating various 20-pin PAL devices across three configuration modes

Applications

• Direct replacement for legacy 16R8 family and other 20-pin combinatorial PLDs
• Complex logic function realization in systems requiring low power consumption
• State machine initialization utilizing automatic power-up reset features
• PCI-compliant digital logic interface designs

Procurement Notes

Verify that the specific ordering suffix XC corresponds to the TSSOP-20 package as defined in the manufacturer's documentation. Confirm compliance requirements such as RoHS status, as standard packages may differ from Green (Pb/Halide-free) options. Ensure the design accounts for the commercial temperature range limits specified for this speed grade.

Selection Notes

Select the ATF16V8CZ-12XC when a 12 ns propagation delay is required within the commercial temperature range. This part is suitable for applications needing reprogrammability without the higher cost of EPROM devices. Consider the TSSOP-20 package constraints if surface mount assembly is necessary. Verify that the system voltage remains within the 5V ±5% tolerance for optimal AC characteristics.
