ATF16V8CZ-12JC

Overview

The ATF16V8CZ-12JC is a high-performance Electrically Erasable CMOS Programmable Logic Device (PLD) utilizing Flash memory technology. It features a maximum pin-to-pin delay of 12 ns and a typical standby current of 5 µA. The device supports commercial temperature ranges (0°C to 70°C) with a 5V ±5% supply voltage. It includes eight configurable macrocells, each allocated eight product terms, and offers three operational modes: registered, complex, and simple. Key electrical characteristics include 200 mA latchup immunity, 2000 V ESD protection, and input/output pin keeper circuits that eliminate the need for external pull-up resistors.

Feature Summary

• High-speed performance with 12 ns maximum pin-to-pin delay
• Low-power operation featuring 5 µA typical standby current
• CMOS and TTL compatible inputs and outputs with internal pin-keeper circuits
• Reprogrammable via advanced Flash technology with 100 erase/write cycles

Applications

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

Procurement Notes

Verify the specific ordering suffix corresponds to the required package type. The 'JC' suffix indicates a 20-lead Plastic J-leaded Chip Carrier (PLCC) package. Confirm the speed grade matches system timing requirements, as this unit is specified at 12 ns. Ensure the application environment falls within the commercial temperature range of 0°C to 70°C. Check for RoHS compliance if lead-free materials are mandated by project specifications.

Selection Notes

Select this component when replacing legacy 20-pin PALs such as the 16R8 or GAL16V8. Choose the registered mode if flip-flop outputs are required; use complex mode for I/O functions with output enable control; or select simple mode for pure combinatorial logic without OE. Ensure the compiler software is configured correctly to match the desired architectural subset. Verify that the 5V ±5% supply tolerance aligns with the target system power rails.

Part Context

This device belongs to the ATF16V8CZ series of electrically erasable PLDs. It serves as a superset architecture capable of emulating various standard PAL devices. The series offers both commercial and industrial temperature variants, with speed grades ranging from 12 ns to 15 ns. The part integrates Flash memory, allowing for reprogramming without UV exposure, distinguishing it from earlier EPROM-based PLDs.

Replacement Considerations

Public confirmed substitutes include other ATF16V8CZ speed grades (e.g., -15JC) or Green package variants (e.g., ATF16V8CZ-15JU) if industrial temperature range is acceptable. Commercial parts may be used in industrial ranges by downgrading one speed grade and de-rating power by 30%. No direct cross-brand equivalents are documented in the source material.
