ATF16V8CZ-12PC

Overview

The ATF16V8CZ-12PC 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 100 erase/write cycles. 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 5V supply with ±5% tolerance.

Feature Summary

• High-speed performance with 12 ns maximum pin-to-pin delay
• Low-power architecture featuring 5 µA typical standby current
• CMOS and TTL compatible inputs and outputs with internal pin-keeper circuits
• Reprogrammable via electrically erasable Flash memory technology

Applications

• Direct replacement for industry-standard 20-pin PAL devices such as the 16R8 family
• Complex logic function realization in systems requiring low power consumption
• PCI-compliant digital logic applications

Procurement Notes

Verify that the specific ordering suffix PC corresponds to the 20-lead Plastic Dual Inline Package (PDIP). Confirm the device meets RoHS compliance requirements if lead-free packaging is necessary for the assembly process. Ensure the application environment remains within the specified commercial temperature range of 0°C to +70°C.

Selection Notes

Select this component when a 12 ns speed grade is required for commercial temperature operations. The PDIP package is suitable for through-hole mounting. Consider the -15PC variant if a slower speed grade allows for potential cost optimization or if system timing margins require less stringent delay specifications.

Part Context

This part belongs to the ATF16V8CZ series of EEPLDs, which are designed to emulate various 20-pin PAL architectures. The 'C' designation indicates commercial temperature range operation, while the '12' specifies the 12 ns speed grade. The 'P' denotes the PDIP package type, and 'C' at the end typically signifies standard commercial grading in this context.

Replacement Considerations

ATF16V8CZ-15PC is a slower speed variant within the same package and temperature range. ATF16V8B-15PU is an older generation EEPLD with similar functionality but different manufacturing technology and potentially different power characteristics.
