ATF16V8B-10JU

Overview

The ATF16V8B-10JU is a high-performance CMOS Electrically-Erasable Programmable Logic Device (EE PLD) manufactured by Microchip Technology. It utilizes Atmel’s Flash memory technology and features an industry-standard architecture that emulates many 20-pin PALs. The device provides 10 input pins, 8 I/O pins, and 8 macrocells with dedicated product terms. It operates at a maximum pin-to-pin propagation delay of 10 ns and supports a maximum frequency of 68 MHz in external feedback configurations. Designed for industrial applications, it functions within a temperature range of -40°C to +85°C using a 5.0V ± 10% power supply.

Feature Summary

• Industry-standard 20-pin architecture compatible with common PAL replacements
• High-speed performance with 10 ns maximum pin-to-pin delay
• Advanced Flash memory technology allowing reprogramming and 20-year data retention
• CMOS and TTL compatible inputs/outputs with internal pull-up resistors

Applications

• Direct replacement for legacy 16R8 family and other 20-pin combinatorial PLDs
• Industrial control systems requiring reliable programmable logic
• PCI-compliant interface designs

Procurement Notes

Verify the component matches the specific 10 ns speed grade and Industrial temperature rating (-40°C to +85°C). Confirm the package type is 20-lead Plastic J-leaded Chip Carrier (PLCC), designated as package code 20J. Ensure the part number suffix indicates RoHS compliance and lead/halide-free construction as specified in the ordering information table.

Selection Notes

Select this variant when a 10 ns delay is required for faster signal processing compared to the 15 ns version. The ATF16V8B-10JU is suitable for designs needing standard 20-pin footprint compatibility without low-power standby modes. Note that the BQL variants offer automatic 5mA standby but are distinct from the standard B series.

Part Context

This component belongs to the ATF16V8B family of EE PLDs. The '10' suffix denotes the 10 ns speed grade, while 'JU' identifies the 20-lead PLCC surface-mount package. This specific part is designed for industrial temperature ranges and replaces older commercial-grade options that have been obsoleted.

Replacement Considerations

The ATF16V8BQ has been replaced by the ATF16V8B and ATF16V8BQL series. When replacing legacy PALs, ensure the compiler software is configured for the correct emulation mode (Registered, Complex, or Simple) to match the target device's pinout and logic structure.
