ATF16V8B-10JI

Overview

The ATF16V8B-10JI is a high-performance CMOS electrically erasable programmable logic device (PLD) manufactured by Microchip Technology. It utilizes Atmel’s Flash memory technology and features eight macrocells with registered, complex, or simple modes of operation. The device operates at a maximum pin-to-pin delay of 10 ns and supports a 5V supply voltage with ±10% tolerance for industrial temperature ranges (-40°C to +85°C). It provides 20 pins in a PLCC package, offering CMOS and TTL compatible inputs/outputs with internal pull-up resistors.

Feature Summary

• Industry-standard architecture emulating many 20-pin PALs
• High-speed performance with 10 ns maximum pin-to-pin delay
• Advanced Flash technology allowing reprogramming and 100 erase/write cycles
• CMOS and TTL compatible I/O with internal pull-up resistors

Applications

• Industrial control systems requiring reliable logic functions
• Replacement for obsolete 20-pin combinatorial PLDs
• Complex digital logic design using registered or combinatorial outputs

Procurement Notes

Verify the specific ordering suffix 'JI' corresponds to the Industrial temperature range (-40°C to +85°C) and 20-lead PLCC package as defined in the official Microchip ATF16V8B datasheet. Confirm that the component meets the required electrical specifications for your application environment before procurement.

Selection Notes

Select the ATF16V8B-10JI when an industrial temperature rating is necessary alongside a 10 ns speed grade. Ensure the design accommodates the 20-lead PLCC footprint. Consider lower power variants like the BQL series if system power constraints are critical, as this standard version draws up to 95 mA active current.

Part Context

This part belongs to the ATF16V8B family of high-performance EE PLDs from Microchip (formerly Atmel). The family includes commercial and industrial temperature variants, as well as low-power options (BQ and BQL). The ATF16V8B-10JI specifically targets applications needing robust industrial reliability with fast switching speeds.

Replacement Considerations

The ATF16V8B-10JI can directly replace most 20-pin PAL devices due to its superset architecture. Verify compatibility with existing programming tools and ensure the target application does not require higher speed grades than 10 ns.
