ATF16V8B-15JC

Overview

The ATF16V8B-15JC is a high-performance CMOS electrically erasable programmable logic device (EEPLD) utilizing Flash memory technology. It features eight macrocells with eight product terms each, supporting registered, complex, and simple modes of operation. The -15 speed grade specifies a maximum pin-to-pin propagation delay of 15 ns and an input setup time of 12 ns. Designed for commercial applications, it operates within a 0°C to 70°C ambient temperature range at a nominal 5V supply voltage.

Feature Summary

• Emulates industry-standard 20-pin PAL architectures including 16R8, 16L8, and 10L8 families.
• Features advanced Flash technology allowing reprogramming with 100 erase/write cycles and 20-year data retention.
• Includes internal pull-up resistors on all inputs and I/Os to ensure known logic states when undriven.
• Provides hardware security via a single fuse that inhibits verify and preload functions upon programming.

Applications

• Direct replacement for obsolete 16R8 series PLDs in existing designs.
• Implementation of state machines requiring power-up reset initialization.
• General-purpose combinatorial logic and bi-directional buffering.
• PCI-compliant interface logic circuits.

Procurement Notes

Verify the ordering suffix 'JC' corresponds to the 20-lead Plastic J-leaded Chip Carrier (PLCC) package and Commercial temperature range (0°C to 70°C). Confirm the specific speed grade (-15) matches the required 15 ns timing constraints for the target system clock frequencies.

Selection Notes

Select this component when a reprogrammable solution replacing legacy 20-pin PALs is required. The -15 speed grade offers a balance between switching speed and power consumption compared to faster or slower variants. Ensure the design utilizes the standard pinout compatible with the PLCC-20 footprint.

Part Context

This part belongs to the ATF16V8B family, which includes low-power variants such as ATF16V8BQ and ATF16V8BQL. While the base ATF16V8B draws approximately 55 mA standby current, the BQ and BQL versions offer significantly reduced power consumption suitable for battery-operated systems.

Replacement Considerations

The ATF16V8B-15JI serves as the industrial temperature variant of this component, operating from -40°C to 85°C. Other speed grades within the same package include ATF16V8B-10JC and ATF16V8B-25JC.
