ATF16V8B-15JU

Overview

The ATF16V8B-15JU is a high-performance Electrically-Erasable Programmable Logic Device (EEPLD) manufactured by Microchip Technology. It utilizes advanced Flash memory technology and operates within an industrial temperature range of -40°C to +85°C. The device features 20 I/O pins, 8 macrocells, and a maximum propagation delay of 15 ns. It supports a supply voltage of 5.0V ± 10% with a typical standby current of 55 mA. Packaged in a 20-lead Plastic J-leaded Chip Carrier (PLCC), it emulates industry-standard 20-pin PAL architectures.

Feature Summary

• High-speed performance with 15 ns maximum pin-to-pin delay
• Flash-based architecture allowing reprogramming and 100 erase/write cycles
• CMOS and TTL compatible inputs and outputs with internal pull-up resistors
• Industrial temperature range operation (-40°C to +85°C)

Applications

• Direct replacement for legacy 20-pin PAL devices such as the 16R8 family
• Complex logic function implementation using configurable macrocells
• State machine initialization utilizing power-up reset features

Procurement Notes

Verify that the component matches the PLCC-20 package designation. Confirm the speed grade corresponds to the 15 ns specification. Ensure the ordering suffix indicates compliance with RoHS standards if required by the design specifications.

Selection Notes

Select this part when replacing standard 20-pin PALs requiring electrically erasable functionality. The registered mode supports clocked outputs, while complex and simple modes allow flexible combinatorial logic configurations. Verify software compiler compatibility for automatic mode selection.

Part Context

This component belongs to the ATF16V8B series of EEPLDs. It serves as a modern alternative to obsolete bipolar PAL devices, offering non-volatile Flash storage and lower power consumption compared to traditional EPROM-based PLDs.

Replacement Considerations

ATF16V8B-10JU provides a faster 10 ns speed grade in the same package.
