ATF16V8CZ-15JC

Overview

The ATF16V8CZ-15JC is a high-performance Electrically Erasable CMOS Programmable Logic Device (EEPLD) manufactured by Microchip Technology. It utilizes Flash memory technology to provide reprogrammability with up to 100 erase/write cycles and 20-year data retention. The device features 8 macrocells, each allocated 8 product terms, supporting Registered, Complex, and Simple logic modes. Key electrical specifications include a maximum propagation delay of 15 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 (±5%) and offers CMOS/TTL compatibility.

Feature Summary

• High-speed performance with 15 ns maximum pin-to-pin delay
• Low-power architecture featuring 5 µA typical standby current
• Reprogrammable via electrically erasable Flash memory technology
• Supports Registered, Complex, and Simple logic configurations

Applications

• Replacement for legacy 20-pin PAL devices such as 16R8 and 16L8 families
• State machine initialization requiring power-up reset capabilities
• Systems requiring automatic power-down in slow clock or asynchronous applications

Procurement Notes

Verify that the specific ordering suffix 'JC' corresponds to the PLCC-20 package and Commercial temperature range (0°C to +70°C). Confirm RoHS compliance status, as standard packages may differ from Green (Pb/Halide-free) options like the -JU suffix. Ensure programming equipment supports the ATF16V8CZ architecture and Flash-based verification protocols.

Selection Notes

Select this component when replacing obsolete 20-pin combinatorial or registered PLDs. Choose the Registered mode if flip-flops are required; use Complex mode for I/O functions with output enable control; or use Simple mode for pure combinatorial logic without OE. Ensure the design accommodates the 5V ±5% supply tolerance and 15 ns timing constraints.

Part Context

This part belongs to the ATF16V8CZ series of EEPLDs, which supersede earlier ATF16V8B variants. The 'C' designation indicates the use of advanced Flash technology compared to the EEPROM-based B-series. The '15' denotes the 15 ns speed grade, and 'JC' specifies the Plastic J-leaded Chip Carrier (PLCC) package for commercial temperature operation.

Replacement Considerations

Direct architectural replacement for GAL16V8, 16R8, 16L8, and 16H8 devices. For industrial temperature requirements (-40°C to +85°C), consider the ATF16V8CZ-15JI variant. Note that the ATF16V8B series uses different memory technology and may require software recompilation.
